Aluminum ore crushing overcomes mud problem

Special | LZZG

Sand and gravel sieve can sift many materials, such as ore, aluminum powder, copper powder, sand, ore, alloy powder, sand, stone, abrasive powder, refractory material, limestone, quartz sand, and other materials. The hydraulic mud desiler has a mud cyclone desander, which first pumps the mud into a funnel container by a sand pump.

Crusher

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.
