How does a small jaw crusher affect the wear of Crusher liners?

Using a small jaw crusher, the wear of the crusher liners has been studied for different settings of the crusher. The experiments have been carried out using quartzite, known for being very abrasive. Crushing forces have been measured, and the motion of the crusher has been tracked along with the wear on the crusher liners.

Do Crusher liners wear?

Crushing forces have been measured, and the motion of the crusher has been tracked along with the wear on the crusher liners. The test results show that the wear mechanisms are different for the fixed and moving liner. If there were no relative sliding distance between rock and liner, Archard’s model would yield no wear.

How do liners affect the performance of a crusher?

The properties and performance of the crusher are strongly dependent on the stroke and bed thickness. Because of wear, these geometric quantities will change during the life of the liners. In turn, when the geometry of the liners changes, the performance of the crusher will change. With very few exceptions, this will be a detrimental effect.

How does wear affect the design of a crusher?

The geometry of the crusher will change because of wear. Being able to predict the worn geometry will help optimising the design of the new crusher for improved performance throughout its lifetime. Current research and knowledge in the field of wear is very extensive.

What causes a jaw crusher to harden?

There are various explanations for this strain-induced hardening; but the major mechanisms that drive the transformation are twinning and slipping of dislocations ( El Bitar and El Banna, 2000 ). The small jaw crusher was used to study the wear as a function of force (i.e. pressure) and motion.

How do you measure the wear of Crusher liners?

The forces were registered and the motion of the crusher was measured by recording a signal indicating the eccentric angle of the main shaft. Wear of the liners was measured on a 13 by 8 grid with 10 mm spacing on each liner. The average wear on each level in the downward direction was computed.
