Grinding Material Comparison. Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and ...

Large receiving opening per dollar of investment. Shape of receiving opening favourable for blocky feed. This, plus point 1, give the jaw a definite advantage over the gyratory, except in the very large sizes, for handling rock of massive formation. The jaw crusher is more easily adjusted, to compensate for wear of liners.

Roll Crushers are compressiontype machines, so output gradation is controlled mainly through the gap setting between the rolls. A wider setting results in a coarser product. A wider setting also provides greater throughput. Single Roll Crushers feature a lowspeed crushing roll that crushes material against a curved crushing plate.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
