Double Roll Crusher

Double Roll Crusher

double roll  crusher is widely used for secondary and fine crushing in the industry of mining, building materials, chemical industry, metallurgy and so on. It can crush materials in middle hardness such as rocks, ore, coke, lump coal, slag, mineral slag, cement clinker, fireproof materials, and so on.

The feed material of double roll crusher

Raw materials, secondary raw materials and by-products such as coke duff, coal, rock, fireclay,fertilizer, salt, glass and similar products.

The work process of double roll crusehr

The crushing rolls are driven individually and directly by means of electro-motors or with coupling and gears, counterrotating via V-belts. The material is fed into the machine by means of conveyors while it is spread over the whole width of the roll. The roll diameter grants an optimum angle of entry. The careful adjusting of the roller speed towards the falling speed of the feeding material guarantees a gentle grinding process with a minimum of wear and tear

Double roll crusher has two wear-resistant rollers. The two rollers turn relative together to make high pressure to crush the material. The material is entered into the space between the two rollers, suffered both extrusion and shear force. In the crusher rolling, cutting and  grinding, it is crushed into the required size and then discharged by the transport equipment.

the special characteristics of smooth roll crusher

The roller shells are wearing parts, and are therefore connected to the roller shafts by roller discs and braced with tie rods. This effective assembly method makes the constant reutilization of the supporting roller structure and the quick replacement of worn roller shells possible.

The roller shells are made of highly wear-resistant cast alloys. The possible efficiency is between 60 and 70 per cent of the cover thickness. In order to facilitate maintenance, the smooth roller shafts are arranged in labyrinth-sealed plummer blocks with lubricated, amply dimensioned spherical roller bearings.

Depending on the hardness of the feeding material,a machining of the roller surface at different intervals is necessary. This can easily be done by an optional machining device. Thus the installed rolls can be exactly cylindrically turned.
