Exceptional crushing capacity with minimum power consumption is
obtained by unique moveable jaw principle. The upper end of the
jaw travels in a circular path driven by the eccentric shaft.
The lower end oscillates through a short arc described by the
toggle. The resultant jaw action is a forward and downward motion
relative to the stationary jaw that crushes the sample and forces
Heavy bronze bearings are sealed against dust and dirt and are
lubricated by grease cups, so that no special greasing tools are
required. Bearings may be taken up for wear, reversed on the shaft
for more wear, and after long service, easily replaced.
the Chipmunk Crusher is easily accomplished. The stationary jaw is
easily lifted out of the frame to completely expose the inner parts
for thorough brushing. Dropping the cam-lock handle anchors the jaw
securely in position.
The discharge opening between jaw can be adjusted to control crushed
particle size by turning a hand wheel on the side of the crusher.
The adjusting mechanism consists of wedge blocks operated by a screw.
The blocks transmit crushing force from the jaw to the frame relieving
all strain on the adjusting screw itself.
