Marcy® Double Roll Crushers

The Marcy Double Roll Crusher meets your requirements for intermediate crushing of friable rock or rock-like materials

Double Roll Crushers are useful for intermediate size reduction of hard to medium hard materials, such as rock or ore, after processing with a jaw crusher, for final reduction with a pulverizer. They also bridge the gap between laboratory and continuous production or pilot plant crushing capacities. Especially recommended for assay offices, metallurgical, soil and other commercial or industrial laboratories.

Application: mining industry, high capacity intermediate crushing

The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particles. The two rolls force the particles between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.

– High capacity intermediate crushing – Heavy duty equipment with minimal maintenance. – Final fineness easily set by setting gap between rolls
