Industrial Double Coal Roller Crusher Machine Engaged in Manufacturing Crusher for 18 Years

1. Manda Machinery Plant engaged in manufacturing crusher for 18 years.

2. It applies to cement, chemical industry, electric industry, metallurgy, construction, refractory material etc.

3. It is usually used in middle and fine crushing stage to crush medium hardness materials including wood,limestone, furnace slag, coke, coal, steel slag, salt, shale, good used in all kinds of ore, stone, rock fine crushing.

Double Roll Crushe Working Principle:

1). The materials to be crushed fall from the feeding mouth to the space between the two rolls.

2). After being squeezed and crushed, the final products will naturally fall.

3). 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,

4). 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.

5). Double roller crusher's 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.  

Double Roll Crusher Advantages

1. It gives a very fine product size distribution and produces very little dust or fines.
2. It is effectively used in minerals crushing where the ores are not too abrasive and it is also used in smaller scale production mining of more abrasive metal ores, such as gold.
3. Besides, this roller is easy to operate, low in consumption, stable in running and simple in fabrication.
4. It is stable operation, easy maintenance, low cost, output size adjustable.
