Description FIELD OF THE INVENTION
The present invention generally relates to crushers and, more specifically,
to cone crushers.
BACKGROUND OF THE INVENTION
Cone crushers typically include a frame supporting a crusher head
and a mantle secured to the head. A bowl assembly including a bowl
and bowl liner are supported by the frame so that an annular space
is formed between the bowl liner and the mantle. In operation, larger
particles are fed into the annular space between the bowl liner
and the mantle. The head, and the mantle mounted on the head, gyrate
about an axis, causing the annular space to vary between a minimum
and a maximum distance. As the distance between the mantle and the
bowl liner varies, the larger particles are impacted and compressed
between the mantle and the bowl liner. Through a series of blows,
the particles are crushed and reduced to the desired product size,
and then discharged from between the mantle and the bowl liner.
Cone crushers are operable to reduce large aggregate into medium
sized aggregate particles, and to further reduce medium sized particles
to small sized aggregate particles. Cone crushers can be adjusted
in set up to provide the desired output for a given size feed. One
set up parameter that can be varied is the size and configuration
of the bowl liner used to crush the aggregate. The use of different
bowl liners for different desired aggregate outputs is generally
known. It is also known to provide a cone crusher with a locking
mechanism to fix a bowl liner to the associated bowl.
SUMMARY OF THE INVENTION
One of the problems with known bowl liner locking mechanisms is
that the mechanisms are not fully capable of accommodating variations
in bowl liner configurations due to manufacturing tolerances, imperfections
in materials, etc . . . . Such variations have heretofore been addressed
by the use of shims and the like placed between the components of
the locking mechanisms and the bowl liner. Alternatively, this problem
can be addressed by manufacturing and assembling bowl liners with
a high degree of precision. Such precision manufacturing and assembly
techniques required in prior cone crushers increases the overall
cost of known cone crushers.
Another problem associated with known crusher designs arises when
a first bowl assembly which includes a first bowl liner needs to
be modified so as to include a second bowl liner that is of different
size than the first bowl liner. An example of this problem is the
use of the crusher to perform a secondary crushing operation using
a secondary bowl liner and to subsequently perform a tertiary crushing
stage with a tertiary bowl liner that is sized differently from
the secondary bowl liner. In such a case, it is often necessary
to provide a second bowl that is appropriately configured and sized
to cooperate with the second bowl liner. This thus requires an inventory
of multiple bowls to be maintained, which increases the cost of
operating known crushers.
To overcome this problem associated with existing cone crushers,
the present invention provides a cone crusher which is adaptable
to be alternatively operable with bowl liners of differing sizes
and configurations. Also, the present invention provides a cone
crusher with a locking mechanism that is independently adjustable
between a bowl and a bowl liner so as to have the capacity to accommodate
slight variations in bowl liner configuration from nominal design
dimensions. The invention thus provides a cone crusher that has
the capacity to use bowl liners of varying sizes and configurations
without the need for prior precision manufacturing and assembly
techniques and without the need for shims and the like.
In one embodiment, the invention provides a cone crusher with an
adjustable bowl liner locking assembly for fixing a bowl liner to
a bowl.
In another embodiment, the invention provides a cone crusher adapted
to be alternatively operable with either a first bowl liner or a
second bowl liner. In this embodiment, the invention provides a
crusher including an adjustable locking means for alternatively
fixing either the first bowl liner or the second bowl liner to the
bowl.
In another embodiment, the invention provides a cone crusher adapted
to be alternatively operable with either a first bowl liner or a
second bowl liner, a locking mechanism for fixing the first and
second bowl liners in place, and a feed cone adapter which can be
used in conjunction with either the first bowl liner or the second
bowl liner. This feature of the invention is advantageous by the
elimination of an inventory of multiple feed cone adapters used
with different sized bowl liners.
More particularly, the invention provides a cone crusher including
a frame and a crusher head supported by the frame. The cone crusher
also includes a bowl supported by the frame in spaced relation to
the crusher head and a bowl liner having an inlet end and a locking
flange. The cone crusher also includes a bowl liner locking assembly
for fixing the bowl liner to the bowl in a surrounding relation
to the crusher head. The locking assembly includes a wedge member
providing a locking surface engagable with the locking flange, and
a first link connected to the wedge and engaged with the bowl, and
a second link connected to the wedge. The first and second links
each have adjustable lengths. By adjusting the lengths of the first
and second links, the wedge can be positioned to engage the locking
flange of the bowl liner and to accommodate deviations in the exact
position of the locking flange from the nominal design of the bowl
liner.
The cone crusher is adapted to be alternatively operable with either
a first bowl liner or a second bowl liner, the first and second
bowl liners each having an inlet end and a locking flange extending
therefrom, a bowl mounting surface and a respective predetermined
length extending between the inlet end and the bowl mounting surface.
The crusher includes a bowl having a bowl liner mounting surface.
The bowl also includes a mounting pocket located a predetermined
distance from the bowl liner mounting surface. The bowl also includes
a lock mount located at a second predetermined distance from the
bowl liner mounting surface. The first link of the locking assembly
is adapted to be received by either the lock pocket or the lock
mount.
When the first link is in the mounting pocket, the locking assembly
is mounted on the bowl in position to fix the first bowl liner to
the bowl. Alternatively, when the first link is in the lock mount,
the locking mechanism is mounted on the bowl in a position for fixing
the second bowl liner to the bowl. Thus, the crusher is capable
of using a first bowl liner, such as a secondary crushing stage
bowl liner with the locking mechanism in a first position on the
bowl, and also a second bowl liner, such as a tertiary stage bowl
liner, with the same locking mechanism located in a second mounting
position.
One feature of the present invention is that by providing an independent
fully adjustable locking assembly to secure a bowl liner to a bowl,
the cone crusher affords a greater degree of imprecision in the
manufacture of both the cone crusher and the bowl liners.
Another feature of the invention is the provision of a crusher
that can be used with multiple sizes of bowl liners with a single
bowl and locking mechanism.
Another feature of the invention is that the cone crusher includes
a single feed cone adapter that can be used in conjunction with
different sizes of bowl liners. This eliminates the need for having
multiple feed cone adapters for use with different sizes of bowl
liners.
Other features and advantages of the invention will become apparent
to those skilled in the art upon review of the following detailed
description, claims and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The drawings illustrate a cone crusher 10 embodying the invention.
As shown in FIG. 1 the cone crusher 10 includes a frame 12 a drive
system 14 (a portion of which is shown), and a crusher head 16 supported
by the frame 12 for gyration about a central crusher axis 18. The
head 16 is driven by the drive system 14 for gyration or eccentric
rotation about the axis 18. A mantle 20 is mounted on the outer
surface of the head 16 and provides a generally frustoconical crushing
surface 22.
The cone crusher 10 also includes an eccentric assembly 24 which
operates to laterally locate the head 16 and which determines the
eccentricity of the gyration of the head 16. While various suitable
constructions of the eccentric assembly 24 can be used successfully,
the preferred arrangement and construction of the eccentric assembly
24 provides the cone crusher 10 with a mechanism for varying the
throw of the crusher 10. The eccentric assembly 24 is fully disclosed
in U.S. application Ser. No. 08/173037 filed Oct. 14 1998 and
titled "VARIABLE THROW ECCENTRIC CONE CRUSHER AND METHOD FOR
OPERATING THE SAME"; which is incorporated herein by reference.
The cone crusher 10 also includes a counterweight assembly 26 to
counteract the forces resulting from the gyration of the head 16
and the eccentric assembly 24. While various suitable constructions
of the counter-weight assembly 26 can be used successfully, the
preferred arrangement and construction of the counter-weight assembly
26 includes a first counterweight 28 and a second counterweight
30. The arrangement and construction of the counterweight assembly
26 is fully disclosed in U.S. application Ser. No. 08/172987 filed
Oct. 14 1998 and titled "ECCENTRIC CONE CRUSHER HAVING MULTIPLE
COUNTERWEIGHTS", which is incorporated herein by reference.
The cone crusher 10 also includes an adjustment ring 32 which is
supported on the frame 12 and which supports a bowl assembly 33.
The bowl assembly 33 includes a bowl 34 and a bowl liner 36 such
as bowl liner 36A shown in FIG. 4 or alternatively bowl liner 36B
shown in FIG. 5. The bowl assembly 33 is moveable relative to the
adjustment ring 32 along the axis 18.
The bowl 34 is generally ring-shaped and surrounds the bowl liner
36. The bowl 34 includes an inner surface 38 an outer surface 40
an upper face 42 and a lower face 44. The outer surface 40 is threaded
and engages the adjustment ring 32. The inner surface 38 is generally
configured to receive the bowl liner 36 and to accept crushing forces
transferred from the bowl liner 36 to the bowl 34. The inner surface
38 includes (FIGS. 7 and 8) a generally cylindrical side wall 48
which extends downward from the upper face 42. For reasons discussed
below, the side wall 48 has therein a plurality of vertically extending
grooves or slots 50 which are circumferentially spaced apart about
side wall 48.
The inner surface 38 of the bowl 34 also includes an inwardly extending
shelf 52 that is located intermediate the upper face 42 and lower
face 44. The shelf 52 faces the upper portion of the bowl 34 and
is located adjacent the lower extent of the side wall 48. In general,
the shelf 52 defines the most narrow constriction or opening of
the interior space defined by the bowl 34. This opening or throat
limits the size of the bowl liner 36 that can be housed by the bowl
34 because the upper portion of the bowl liner 36 must be able to
pass by the shelf 52 during assembly of the bowl 34 and bowl liner
36.
The inner surface 38 of the bowl 34 also includes (FIGS. 7 and
8) a frustoconical portion 66 which tapers radially outwardly from
below the shelf 52 toward the lower face 44. The inner surface 38
of the bowl 34 also includes a bowl liner mounting surface 68 which
is located adjacent the lower face 44 and immediately below the
frustoconical portion 66. The bowl liner mounting surface 68 mates
with a portion of the bowl liner 36 supported by the bowl assembly
33 in a manner discussed below.
FIG. 9 illustrates a typical bowl liner 36 included in the bowl
assembly 33. The bowl liner 36 has opposite upper and lower ends
70 72 and a generally frustoconical, hollow body 74 extending between
the upper and lower ends 70 72. The upper end 70 of the liner 36
provides an annular, axially facing feed cone sealing surface 76
and defines an inlet 78 opening into the interior of the body 74.
The bowl liner 36 also has a locking flange 80 that extends radially
from the upper end 70 adjacent the feed cone sealing surface 76.
The diameter of the locking flange 80 is smaller than the size of
the opening defined by the shelf 52 on the bowl 34 so that the upper
portion of the bowl liner 36 can pass by the shelf 52.
As shown in FIG. 9 the underside 82 of the locking flange 80 provides
a wedging surface 84 which is used to fix the bowl liner 36 in position
relative to the bowl 34. For reasons discussed below, the bowl liner
36 is ramped or scalloped to provide a plurality of wedging surfaces
84.
The outer surface 86 of the bowl liner 36 extends between the ends
70 72 and provides a bowl mounting surface 90 located at a predetermined
distance L generally from the inlet end 70 and specifically from
the underside of the locking flange 82. The bowl mounting surface
90 extends around the entire lower end 72 of the bowl liner 36.
As discussed in detail below, and as shown in FIGS. 4 and 5 when
the bowl liner 36 is mounted on the bowl 34 the bowl mounting surface
90 mates with the bowl liner mounting surface 68 to form a cavity
94 between the outer surface 86 of the bowl liner 36 and the frustoconical
surface 66 of the bowl 34.
The cone crusher 10 also includes a filler ring 96 which occupies
the cavity 94 and bolsters the bowl liner 36 so that crushing forces
are transferred to the bowl 34.
As mentioned above, the cone crusher 10 is adapted to be alternatively
operable with either a first bowl liner or a second bowl liner.
This is desirable, for example, in crushing applications wherein
the crusher 10 is used alternatively to perform a secondary crushing
stage and a tertiary crushing stage. In the illustrated embodiment,
the crusher 10 is capable of using a secondary stage bowl liner,
shown in FIG. 4 as bowl liner 36A, as well as a tertiary stage bowl
liner which is shown in FIG. 5 as bowl liner 36B and which may differ
in size and configuration from the secondary bowl liner 36A.
More particularly, the liners 36A and 36B share a common overall
shape, but may have different dimensions and surface angles to provide
different crushing effects. Such variations are known in the art.
of particular relevance to the use of the bowl liners 36A and 36B
as components in the bowl assembly 33 however, are the respective
overall lengths L1 and L2 of the bowl liners 36A, 36B and how the
lengths L1 L2 of the liners 36A, 36B result in different alignments
with the bowl 34. Referring particularly to FIG. 9 a bowl liner
36 has a predetermined length L extending between the bowl mounting
surface and the underside of the locking flange. In the case of
bowl liner 36A shown in FIG. 4 the length L1 differs from (FIG.
5) the length L2 of the liner 36B.
In the context of the bowl assembly 33 the bowl liner mounting
surface 68 at the lower end of the bowl 34 engages and mates with
the bowl mounting surface 90 on the associated bowl liner 36 without
regard to the overall length L of the particular bowl liner 36 used
in the bowl assembly 33. As a consequence, the differences in length
L among bowl liners 36 result in the upper portions of the bowl
liners 36 being located differently relative to the upper portion
of the associated bowl 34. For example, in FIG. 4 the bowl liner
36A is positioned on bowl 34 and the locking flange 80 is located
above the shelf 52. In contrast, the locking flange 80 of bowl liner
36B (shown in FIG. 5) when mounted on the bowl 34 extends above
the shelf 52 but at a lesser degree. Thus, the respective wedging
surfaces 84 of the bowl liners 36A and 36B are aligned differently
with respect to the bowl 34 when each is made a component of the
bowl assembly 33.
In order to provide a crusher adapted to be alternatively operable
with either a first bowl liner having a first predetermined length
or a second bowl liner having a predetermined length different from
the first length, such as with bowl liners 36A and 36B, the crusher
10 also includes locking means 98 for alternatively fixing the first
bowl liner 36A and the second bowl liner 36B to the bowl 34. While
various suitable constructions of the locking means 98 can be successfully
used, in the illustrated embodiment, the locking means 98 includes
a plurality of lock pockets 100 formed in the bowl 34. As explained
below, the lock pockets 100 are positioned for receiving respective
locking assemblies 102 when the second bowl liner 36B is used as
a component of the bowl assembly 33.
More particularly, and as best shown in FIG. 7 the plurality of
lock pockets 100 are spaced apart and circumferentially positioned
around the annular shelf 52 on the bowl 34. Each lock pocket 100
is a recess in the shelf 52 and includes a cylindrical mounting
surface 108 and a pair of spaced-apart side walls 110.
The locking means 98 also includes a plurality of lock mounts 112
formed in the bowl 34 for receiving respective locking assemblies.
As explained below, the lock mounts 112 are positioned for receiving
respective locking assemblies 102 when the first bowl liner 36A
is used as a component of the bowl assembly 33. The lock mounts
112 are also spaced apart and circumferentially positioned around
the annular shelf 52 on the bowl 34 in alternating relation to the
lock pockets 100. Each lock mount 112 extends upwardly from the
shelf 52 and therefore is located closer to the upper face 42 of
the bowl 34 than the shelf 52 and lock pockets 100. In other words,
each lock mount 112 is located a greater distance from the bowl
liner mounting surface 68 than a corresponding lock pocket 100.
Each lock mount 112 provides a cylindrical mounting surface 114
which is spaced above the upper surface of the shelf 52. Each mounting
surface 114 is bounded by a pair of spaced-apart side ears 116.
The cylindrical mounting surface 114 and associated side ears 116
define therebetween a recess that has configuration similar to that
of the recess defined by each of the pockets 100. As shown in FIGS.
7 and 8 the side ears 116 each have bores extending therethrough,
thus affording use of the ears 116 as lifting lugs for handling
the bowl 34.
While any number of lock pockets 110 and lock mounts 112 can be
used for the particular bowl assembly 33 needed for a crusher 10
in the illustrated embodiment of the crusher, the locking means
provides a set of six lock pockets 100 and a set of six lock mounts
112 alternately arranged in spaced relation about the circumference
of the annular shelf 52.
The locking means 98 also includes (FIGS. 2 and 3) a plurality
of locking assemblies 102 which are mounted on the bowl 34 and which
engage the bowl liner 36 and the bowl 34 to fix the bowl liner 36
to the bowl 34 in surrounding relation to the crusher head 16. Each
of the bowl liner locking assemblies 102 are identical, and one
will be described in detail.
Each bowl liner locking assembly 102 includes (FIG. 2) a wedge
member 138 having a locking surface 140 and having extending therein
a pair of threaded bores. Each locking assembly 102 also includes
a first link 142 which is connected to the wedge member 138. The
first link 142 may be referred to as a T-bolt. The T-bolt 142 is
of a "T" shape and includes a threaded extension 144 which
is threaded into one of the bores in the wedge member 138. The T-bolt
142 also includes a generally cylindrical base section or mounting
piece 146.
Each bowl liner locking assembly 102 also includes a second link
148 which is connected to the wedge member 138. The second link
148 may be referred to as a T-pin or mounting pin. The T-pin 148
is of a "T" shape and includes a threaded extension 150
and a handle portion 152. The handle portion 152 mates with the
wedge member 138 such that the T-pin 148 is pivotally connected
to the wedge member 138. A spherical nut 154 and a jam nut 156 are
positioned on the threaded extension portion 150 of T-pin 148. A
locking washer 158 engages spherical nut 154 when the cone crusher
10 is assembled.
FIG. 4 shows a locking assembly 102 fixing bowl liner 36A to bowl
34. The cylindrical base 146 of first link 142 is situated in the
lock mount 112 and supports the wedge member 138 in position under
the locking flange of the bowl liner 36A. The second link extends
horizontally from the wedge member toward the slot 50. A locking
washer 158 overlays slot 50 and provides a seat for receiving the
rounded end of the spherical nut 154. Lock washer 158 may be tack
welded into position. It should be noted that locking washer 158
and slot 50 may be replaced with any suitable means, such as, for
example, appropriately arranged dimples or recesses formed in wall
48.
Because of the complementary shapes of the mounting piece 146 and
mounting surface 114 the first link 142 is pivotable with respect
to the receiving lock mount 112. The first link 142 and second link
148 are positioned so that the locking surface 140 of wedge member
138 engages the locking flange 82 of bowl liner 36. This engagement
tends to lift the bowl liner and pull the bowl mounting surface
at the lower end of the bowl liner 36A into engagement with the
bowl liner mounting surface of the bowl 34. As noted, the underside
of the locking flange 82 is preferably ramped so that the wedge
member 138 is seated on a wedging surface to more securely engage
the locking flange and so as to prevent axial and twisting movement
of the bowl liner 36 relative to the bowl 34 during crusher operations.
FIG. 5 shows a locking assembly 102 fixing the bowl liner 36B to
the bowl 34. In this arrangement the first link occupies the recess
defined by a lock pocket, with the result being that the wedge member
is held in a position lower than when the locking assemblies are
in the lock mounts. When the locking assemblies are in the lock
pockets, the locking assemblies are positioned to support a bowl
liner having a length L2 such as bowl liner 36B, which is shorter
than the length L1 of bowl liner 36A.
When the lock assembly is in a lock pocket, the second link 148
remains engaged with a slot 50 but at a position lower than when
bowl liner 36A is used. The first and second links 142 144 engage
and support the locking flange of bowl liner 36B so that the bowl
liner mounting surface and the bowl mounting surface are engaged.
Thus, the locking means provides a single locking mechanism 98 to
fix the bowl liners 36A and 36B in position relative to the crusher
head and mantle 20 so that the crusher 10 defines an annular space
through which aggregate passes.
The locking means 98 is also adjustable to accommodate deviations
in the size and configuration of the bowl liners 36A, 36B from their
nominal design dimensions. With reference to FIGS. 2 and 5 the
locking means 98 is independently adjustable through adjustment
of the length(s) of the first link 142 and/or the second link 148.
The wedge member 138 may be horizontally translated as the as the
relative to the bowl 34 as the T-pin 148 is threaded in or out with
respect the wedge member 138 and the spherical nut 154. The wedge
member 138 may be vertically translated relative to the bowl as
the T-bolt 142 is threaded in or out of the wedge member 138. As
a result, the camming action of the locking surface 140 can be adjusted
by lengthening or shortening the length of links to assure secure
engagement of the bowl liner 36 and the bowl 34.
With reference to FIGS. 1 4 and 5 the bowl assembly 33 also includes
an upper bowl ring weldment 160 which is fixed, typically by welding,
to the upper face 42 of bowl 34. The weldment 160 extends above
the upper face 42 of the bowl 34. The crusher 10 also includes a
feed cone 166 located concentrically within the bowl weldment 160
and through which aggregate material is fed into the crusher 10.
The feed cone 166 includes a cylindrical wall 168 having upper and
lower ends. The feed cone 166 also includes a locking flange 167
which extends radially outward from the upper end of wall 168 and
which overlays the top of the bowl weldment 160 to support the feed
cone 166 in position above the bowl liner inlet 78. The feed cone
166 also includes a lower flange 170 which extends radially inward
from the bottom of wall 168.
The crusher 10 also includes (FIGS. 4 and 5) a tubular feed cone
adapter 180 which is concentrically arranged within the feed cone
166. The feed cone adapter 180 overlaps the flange 170 of the feed
cone 166 and sealingly engages the inlet 78 of bowl liner 36 to
direct particulates fed into the crusher 10 from the feed cone 166
into the space between the bowl liner 36 and mantle 20. The feed
cone adapter 180 can be used in a first orientation, shown in FIG.
4 to sealingly mate with the upper end 70 of the bowl liner 36A,
and can be alternatively inverted into a second position, shown
in FIG. 5 to sealingly mate with the upper end 70 of the bowl liner
36B. These alternative orientations of the feed cone adapter 180
are needed because of the variation in respective positions of the
upper end 70 of the bowl liners 36A and 36B due to the differences
in their respective lengths L1 and L2.
More particularly, the feed cone adapter 180 has an elongated tube
having the opposite ends 182 184 and a flange 186 extending radially
from the tube. The flange 186 is located intermediate the opposite
ends 182 184 so that the ends 182 184 are spaced an unequal distance
from the flange 186. When the feed cone adapter 180 is in the first
position shown in FIG. 4 a sufficient length of the tube extends
toward the inlet 78 of bowl liner 36A and one of the opposite ends
182 engages a feed cone adapter seal 190 located on the feed cone
sealing surface 76 of the bowl liner 36A. The remainder of the tube
extends above the flange 186 into the feed cone 166. When the feed
cone adapter 180 is inverted, as shown in FIG. 5 a sufficient length
of the tube extends toward the inlet 78 of bowl liner 36B and the
other of the opposite ends 184 engages the feed cone adapter seal
190 located on the feed cone sealing surface 76 of the bowl liner
36B.
