crusher. Primary Crusher — The first crusher in a crushing system into which material is fed. Succeeding crushers in the system are referred to as secondary or tertiary crushers. Product — Output from the crusher. Reduction Ratio — The ratio of the top size of input material to the top size of crusher discharge.

Easy maintenance & low wear. The main wear parts of the jaw crusher are its fixed jaw, moving jaw and cheek plates which can be changed easily and quickly. In contrast to impact crushers, jaw crusher wear parts have a comparatively long service life but jaw crushers cannot achieve the same reduction ratio on material.

The Bond Abrasion Index is a measure of how readily a rock sample will wear away steel that comes into contact with it. It is conventionally used to estimate the liner and media wear rate in rod mills, ball mills and crushers. This is a batch test and returns a result in units of grams (the amount of metal that wears off the test coupon).

The coefficient is known as a wear coefficient and is frequently used to compare the material wear resistance[2,3]. Most of the times, it is estimated experimentally. Although the Archard’s equation was developed for the adhesive wear, it is widely used for modeling of abrasive, fretting and other types of wear[4].
