The present invention is a mobile crusher and a method for controlling
the same, wherein the most suitable amount of crushed substances
can be always secured so as to obtain crushed substances having
a desired particle size distribution. To this end, the crusher mechanism
includes an actual rotational speed changing means (1 2 3); an actual
rotational speed detecting means (4); a rotational speed setting
means (7) for setting at least one target rotational speed Nm for
the crusher mechanism (13) and for setting, for each target rotational
speed Nm, a rotational speed Na indicating a starting of supplying
raw materials and a rotational speed Nb indicating a stopping of
the supplying of raw materials; and a control means (6) for controlling
the crusher mechanism such that an actual rotational speed N coincides
with the target rotational speed Nm, starting the supplying of raw
materials from a raw material supply device (14) when the actual
rotational speed N increases to a rotational speed Na, and stopping
the supplying of raw materials when the actual rotational speed
N decreases to the rotational speed Nb.
A can crusher and storage system is provided including a piston
housing having a first face, a second face, and a periphery formed
therebetween defining an interior space. The piston housing has
an inlet formed in the periphery thereof adjacent the first face.
A thin rectangular outlet is formed in the periphery of the piston
housing between the inlet and the first face and is further situated
opposite of and offset from the inlet. Next provided is a piston
assembly situated within the interior space of the piston housing
for crushing cans situated within the inlet upon the actuation thereof.
A control assembly is provided for selectively actuating the piston
A self-propelled stone crusher includes systems designed to operate
the various machine functions by remote control (30), for operating
on open ground or inside trenches, collecting and crushing rocks
and stones which are then unloaded and levelled behind the machine.
The chassis (3) of the machine is hinged to a shaft (11) integral
with a crawler support structure (5) so that the machine can be
tilted to a greater or lesser extent, depending on the lie of the
land, and the crusher has a hammer mill (10) at the front, the perimeter
of which is formed by a grid consisting of a number of bars (25),
the distance between which varies, depending on the required particle
size of the crushed material.
A conical crusher having a rigidly supported outer frustoconically
shaped crushing member and an inner conical crushing member supported
on a wobble mechanism which is in turn supported by air bellows.
The air pressure in the air bellows is regulated to adjust the spacing
between the inner and outer crushing members, and therefore the
particle size of the crushed material. The inner and outer crushing
members are readily replaceable. The outer crushing member is a
single piece bowl/bowl liner component.
