The Operating principle of jaw crusher:
The electric machine drives belt and belt gear and makes movable
jaw move from up and down by eccentric shaft. When the movable jaw
rises, the included angle between wrist plate and movable jaw,
which pushes movable jaw move towards fixed jaw, and at this time,
the material is crushed and disruptured. When the movable jaw moves
down, the included angle decreases, and the movable jaw plate
leaves the fixed jaw plate under the function of pull rod and
spring. The crushed material discharges below the crushing
cavity.
How to choose suitable crusher:
Material’s physical property, such as breakable, sticky, water
and sediment content and maximum feeding material size and so
on.
Product’s total production volume and grade required can be as
evidence of choosing crusher type and production capacity.
Technical-economic indicator. We have to make required quality
and quantity, simple operation, reliable work and maximum save
cost.
There is a good filling level inside crushing cavity, and the
material is got uniform crush, adding the product pushed out
forcibly, so the high production capacity is doable.
The material is tumble up and down, so it is very easy for
material to discharge in a cubic shape. The product’s quality is
better than the simple pendulum crusher.
Jaw crusher includes PE jaw crusher and PEX jaw crusher. PE jaw
crusher has a large feeding material size, so it is suitable to
coarse crush and primary crush; PEX jaw crusher owns smaller
feeding material size and smaller discharge cavity, so it is used
for second crush.
