Description
The jaw crusher is mainly used as coarse and medium crushing
machine in the mining, building materials, infrastructure and other
sectors, and is categorized into large, medium and small type
according to feed port width size, large type refers to feed port
width above **0mm, medium type refers to the feed port width
ranging from **0mm to **0mm, and small type refers to the feed port
width below **0mm. Jaw crusher features simple structure, easy
manufacture and reliable operation.
The working part of jaw crusher consists of two jaw plates, namely
the stationary jaw vertically (or the upper end slightly inclined)
fixed on the front wall of the body and the movable jaw at an
inclined position, forming the crushing cavity (working cavity) of
large top and small bottom. The movable jaw plate makes periodic
reciprocating motion in opposite to the stationary jaw plate,
sometimes separated and sometimes close. When separated, the
material enters the crushing cavity, and the finished product is
discharged from the lower part. When close, the material which is
arranged between the two jaw plates is crushed under the action of
squeezing, bending and splitting.
The jaw crusher can be categorized into simple swing type jaw
crusher, complex swing type jaw crusher and composite swing type
jaw crusher according to the swing mode of the movable jaw
plate.
