8. CRUSHER
A crusher is a machine designed to reduce
large rocks into smaller rocks, gravel, or rock dust.
The earliest crushers were hand-held stones,
where the weight of the stone provided a boost
to muscle power, used against a stone
anvil. Querns and mortars are types of these
crushing devices.

13. JAW CRUSHER
• A jaw or toggle crusher consists of a set of vertical
jaws, one jaw being fixed and the other being
moved back and forth relative to it by a cam or
pitman mechanism. The jaws are farther apart at
the top than at the bottom, forming a tapered
chute so that the material is crushed progressively
smaller and smaller as it travels downward until it is
small enough to escape from the bottom opening.

14. PRINCIPLE OF JAW CRUSHER
• This jaw crusher uses motor as its power.
Through the motor's wheels, the eccentric
shaft is driven by the triangle belt and slot
wheel to make the movable jaw plate move
by a regulated track. Therefore, the materials
in the crushing cavity composed of fixed jaw
plate, movable jaw plate and side-lee board
can be crushed and discharged through the
discharging opening.
