Roll speed differential is the difference in rotational speed between the two rolls in a pair and is one of the biggest reasons roll crushers produce a grind with a lower standard deviation than hammermills. The differential creates a shearing effect between the rolls that cuts the material rather than squishing it.

Crushing 'Comminution' is the term used to define the process that reduces materials (especially mined ore).It is the action of reducing a material to minute fragments or particles.The process is typically achieved in mining operations through stages of crushing and milling. In the past, mining activities were arduous and labour intensive.

Check whether the oil pump, cooler and filter work well. The scavenge oil must be lower than 60℃. Check the drain of the water seal. If there is no water in the water seal, the crusher must stop running. Pay attention to the sound of engine and gear, and check whether the working current of the motor is normal.

This allows production of a consistent product as well as efficient, reliable operation of the crusher. Choke feeding is important for ™b to maintain approximately 10–15% of material finer than the closed-side setting in the feed to assist the crushing action. More than 10–15% will likely cause ring bounce due to the pressures in the …
