“Computer Aided Design of Jaw crusher”

2010-5-14  Jaw crusher movement is guided by pivoting one end of the swinging jaw. and an eccentric motion located at the opposite end. [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws .For instance, a 22 x 30 jaw crusher has an opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square.

Study on Liner wear in Single Toggle Jaw Crushers: A

2017-7-9  A jaw crusher consists of a fixed jaw and a swing jaw. The swing jaw, which is inclined at an acute angle to the vertically fixed jaw, swings with the help of a pitman mechanism that is mounted on an eccentricshaft. The inertia force for crushing the material is provided by two heavy flywheels mounted at both sides of the eccentric shaft.

COMMINUTION - THEORY AND PLANT PRACTICE

2012-8-16  A Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a "V" alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the "V" aligned jaw plates is the crusher product size gap, or

Rittinger - an overview ScienceDirect Topics

The closed set of an operating jaw crusher was 125 mm. A continuous stream of ore was fed at the rate of 30 t/h. On an average, 10% of the ore was less than the set. The F 80 was 410 mm in size. The crusher was initially operated at 200 rpm at a reduction ratio of 1:4, but the toggle speed was to be increased. Calculate 1.
