Roller Crusher

Roller Crusher made by EMCC (Shanghai) is suitable for various kinds of hard middle hard and soft solid materials ( with no more than 200 mpa compressive strength) fine grinding and ultra fine grinding operation widely used in mining

This protection spring is set at the either head of two movable rollers; the working pressure is designed according to the compressive strength of crushing materials. When the Crusher works this protection spring device has no action on the whole but if the crusher encounters hard metal pieces the protection spring can quickly retreat and it will quickly return to its original position after the hard metal pieces fall.

It adopts high manganese steel 2 Mn13 chromium cast steel structure and then after the machine finishing its roughness can reach above 6.3 applicable to crushing materials with fineness demand for 80 mesh to 3 mm below.

It uses 45 # steel casting structure after machine finish machining and heat treatment. Its surface adopts special alloy wear-resistant steel material overlaying weld with high strength high wear resistance suitable for the fineness requirement for 3 to 30 mm in secondary and fine crushing work.

Feed particle size is large a small particle size the variable multistage crush for the level of fragmentation the full realization of a broken top low cost operation two broken. It can reduce 35% of the cost it is a low energy consumption low investment of equipment.

1 Four-roller Crusher
4 PG series roller crushers use high extrusion pressure and ground shearing force created by the two sets of individually driven grinding rollers through relatively rotating. When materials enter in V-shaped crushing cavity formed by two grinding rollers they will be crushed by two grinding rollers. Small particles after being crushed will be along the tangent of the rollers. Through the clearance of two grinding rollers the material will be extruded and sheared for the first time (coarse crushing) and then again go into the roller below for second extrusion and tooth grinding(fine crushing) . The ideal particles will finally discharge.

2 Double-Roller Crusher
2 PG series roller crusher is mainly composed of frame transmission device crushing roller adjustment device and spring safety device etc. Through the motor triangle pulley drive gear to rotate the roller two rollers relatively rotate. The Ore enters into the crushing space between two rollers due to the effect of friction and will be squeezed and crushed.
Crushed material will discharge through the gap between the two rollers under the action of gravity. The minimum distance between the two rollers is the discharging mouth width.

• Production capacity : 1-120 t/h
• Processable Material : such as glass quartz sand iron ore cement coal coke steel slag coal gangue pebbles limestone silica concrete chemical raw materials and other solid materials with fairly hardness.
• Range of Application : it can be used for intermediate crushing and fine crushing in metallurgy mining chemical industry cement construction refractory materials and ceramic industries etc.

Roller Crusher made by EMCC (Shanghai) is suitable for various kinds of hard, middle hard and soft solid materials ( with no more than 200 mpa compressive strength) fine grinding and ultra fine grinding operation, widely used in mining, cement, thermal power, metallurgy, building materials, chemical industry, etc.
