A vertical shaft impact crusher features a split tub such that
the upper portion carrying the anvil ring and anvils can be removed
as a unit and inverted on the ground for fast and easy anvil removal.
The upper tub portion can also be rotated relative to the lower
portion in order to even out anvil wear quickly and effectively.
An apparatus for crushing multi cavity medication cards wherein
each cavity serves as a receptacle containing individual doses of
medication such as, for example, pills or tablets. The apparatus
includes a frame with a reciprocally movable platen and changeable
medication card support plates mounted below the movable platen.
Dependent upon the configuration of the card to be crushed, a crusher
plate is attached to the platen having protrusions formed thereon
to engage each of the cavities of the card. The card support plate
may be of a substantially solid construction for crushing pills
contained within each cavity of the card, or may be apertured so
as to permit expulsion of the medication from the card as the card
The disclosure relates to an improved rotating impeller table for
a secondary impact crusher comprising a side discharge port containing
housing incorporating dove tailed abrasion resistant wear elements
disposed on the external cylindrical wall thereof. The dovetailed
wear elements overlap and are supported by removable lower edge
wear liners which also protect the outer edge area of the lower
part of the housing. A removable top liner retains the dove tailed
elements in position and protects the upper part of the housing
from abrasion. A removable and repositionable wear ring fits within
an annular opening in the top of the housing and may be repositioned
at least three times to essentially triple its wear life. Upper
and lower centrufugally locking flat and ramped liners are disposed
within the housing on its upper and lower ends. Parallel planar
vertical walls, deflection plates and pins adjacent the side discharge
ports on the housing are uniquely structured and positioned to give
extended wear and optimum results.
A novel bearing construction for use in a cone crusher and the
like in which an eccentric rotating in a frame and a crushing head
gyrating in the inner periphery of the eccentric are movable up
and down by hydraulic pressure. A cylindrical socket inserted in
a sleeve of the frame is slidable up and down while the crushing
head is supported by the upper part of the socket and the eccentric
is supported by the lower part of the socket so that the bearing
are prevented from wear and trouble during operation.
