Overview

Hongji Roller Crushers are compression type crushers, and were once widely used in mining. They have, within the last 10 or so years, fallen into dis-favor among mining and processing companies. The probable reason is because the large mines require very large crushed product output with minimal cost, makes the roll crusher uncompetitive. The roll crushers are not nearly as productive as cone crushers, with respect to volume, and they do have a little higher maintenance associated with them. Roll crushers do, however, give a very close product size distribution, and if the ore is not too abrasive, they do not have high maintenance costs. Roll crusher is mainly used for the crushing of medium or lower-hardness mines and rocks with medium or lower rigidity in mine selection, chemicals, cement and building materials industrial production.

1) Roller crusher equipment is equipped with grinding system, which can not only enhance the production capacity of the equipment, but also can reduce energy consumption.

2) Roller crusher is equipped with scientific design, simple structure, small footprint and easy operation.

3) The machine¡¯s internal dust-proof plate has good tightness, which can help to avoid the small splash dust or materials.

4) Roller crusher has good wear resistance. Wear liners adopt the most advanced wear-resistant materials which have long service life and are not easily damaged.

5) Roller crusher has good security guards and strong self-protection ability, which prevents the crushing chamber from being damaged by material of high hardness.

6) Roller crusher has the advantages of energy saving and environmental protection, strong crushing capacity and the size can be adjusted.

7) Roller crusher is featured with low noise and high efficiency.

Roller crusher structure

These series roller crusher is mainly composed of body, chassis, crushing rollers (fixed roll and moveable rolls), transmission shaft, spring safety device and gear encloser.

Roller Crusher working principle:

There are two cylindrical rollers horizontally installing on mutually parallel racks, where one of the roller bearing is movable and the other roller bearing is fixed. Driven by electric motor, the two rollers do opposite rotation, which produces downward acting force to crush materials between two crushing rollers; broken materials that are in line with the required size are pushed out by roller and discharged from the discharging port.
