In the processes of various grindability tests the same phenomenon occurs, namely the grinding velocity of limestone is significantly higher than that of the corundum or clinker, this leads to the sudden growth of the limestone content in the initial finer 106 m product of the bond measurements and in the 75 m products of the hardgrove.
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. crushers may be used to reduce the size, or change the form, of waste primarily used inpit at the mine face these units are able to move with the to soft materials and non abrasive materials, such as limestone.
