Roller Crusher

Feed Size: ≤25 - ≤100 mm

Processing Capacity: 5 - 100 t/h

Processible Materials: Limestone, slag, coke, coal, salt, chalk, gypsum, alums, brick, tile, etc.

Application Range: To crush medium and high hardness materials in the industries of cement, electricity, chemical engineering, metallurgy, construction materials and refractory matter.

Brief Introduction:

Roll crusher (or roller crusher, teeth roll crusher, double roll crusher) is mainly used for secondary crushing or tertiary crushing of raw materials such as coal, coal gangue, coke, limestone, sulfur ore, phosphate rock and other materials. Its crushing way is roll extrusion, and the compression strength of to-be-broken material does not exceed 80PaM.

Application:

Roller crusher is mainly used for general crushing and fine crushing of ores and rocks with high and medium hardness in mineral processing, chemical, cement, refractory, abrasives, building materials and other industrial sectors.

Characteristics:

1.High productivity and high efficiency.

2.Compact structure, light weight, small size,

3. Operation and maintenance are more convenient.

4. Well sealed, less dust, low noise.

5. Long life expectancy.

6. Simple and reasonable structure, low operating cost, smooth operation

7. Energy saving.

Roller Crusher Working Principle:

The materials to be crushed fall from the feeding mouth to the space between the two rolls, after being squeezed and crushed, the final products will naturally fall. When there are too hard materials or materials that cannot be crushed, the rolls of the roller crusher will automatically withdraw under the effect of hydraulic cylinder or spring to increase the gap between the rolls, and the too hard materials or the materials that cannot be crushed will fall down, thus protecting the machine from being damaged.

There is a certain gap between the two rolls that rotate at the opposite direction, and the maximum discharging granularity of the final products can be controlled by changing this gap. Double roll crusher crushes the materials by relying on the two round rollers rotating at the opposite direction, and four-roll crusher crushes the materials by relying on the two pairs of round rollers rotating at the opposite direction.

The Inner Structure of Roll Crusher:

The main structure of the wheel gearing is composed of fixed roll, movable roll, drive shaft, machine box, chassis, cover piece and long gear cover. The motive power of the machine comes from the V-belt pulley of the electromotor, and a pair of middle reduction gear will make the fixed roll rotate, and then a pair of long gear drive on the other side of the fixed roll will drive the movable roll, and the two rolls perform relative movement to squeeze the materials.
