· Jaw crushers using this method of compression are suitable for reducing extremely hard and abrasive materials. However, some jaw crushers employ attrition as well as compression and are not as suitable for abrasive materials since the rubbing action accentuates the wear on crushing surfaces. As a mechanical reduction method, compression is to be used if the material is hard and .
· 2 Jaw crusher parts especially jaw plates wear badly. Materials that need be crushed is irregular and with different hardness, so it will bring constant friction and stress to the jaw plates. At the same time, moveable jaw moves up and down in vertical direction, which leads to stronger friction between material and jaw plates thus damaging the surface of the jaw plates.
