Hammer grinders are intended for crushing mineral and technological raw material with average hardness up to 7 units as per Mohs scale and temperature of fusion not less than 250°С, with humidity up to 8 % at which there is no sealing of grid-iron lattices..Grinders can be installed both indoors and on the open area under a shed.
Raw material continuously moves through the loading hopper. Crushing occurs due to impact of raw material about hammers, baffle plates of reservations and grid-iron lattices. The ready product spills through apertures in a lattice.
Grinders perfectly have recommended themselves in production of building materials, ceramics, asphalt filler and concrete as well as in crushing glass, rubble, chalk stone (waterless), dolomite, chamotte, waterless metals salts.
As well as in other grinders productivity falls with increase in a degree of crushing and the specific power consumption grows.
Depending on physical properties of a material (hardness, humidity, granulometric size composition of influent and effluent material, etc.), technical characteristics and design features of grinders can vary.
