Computer aided design of jaw crusher

Garnaik, Sobhan (2010) Computer aided design of jaw crusher. BTech thesis.



Due to their simple design and easy maintainability jaw crushers are widely used as primary size reduction equipments in mechanical and mining industries. As jaw crushers break minerals & ores of high strength and the economy of many industries depends on its performance; it is essential to improve the efficiency of the present design. The kinematic analysis of single toggle jaw crusher shows that the forces on the moving jaw plate at different crank angle are different and hence power generated varies with crank angle. One way to increase the efficiency is to store the energy in a flywheel when the supply is more than the rate of consumption and to utilize the same when the supply falls down. Hence efforts are made to design a flywheel to minimize the wastage of power and to improvise the performance parameters of single toggle jaw crusher.

Jaw plate wear has considerable affect on the life of jaw Crusher which is caused by the slipping motion between the fed material and the jaws. This wear is predominantly serious in the fixed plate and hence the liners of the fixed jaw should be properly chosen. In addition to this the toggle bar which acts as a safety lever has to be precisely designed. The design aspects of flywheel, spring of tension bar and toggle bar are discussed in this paper.
