Description

Description of Double roll crusher
 

Double 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. Roll crushers have a theoretical maximum reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines. Rolls crushers are effectively used in minerals crushing where the ores are not too abrasive and they are also used in smaller scale production mining of more abrasive metal ores, such as gold. Coal is probably the largest user of roll crushers, currently, though. Coal plants will use roll crushers, either single roll or double roll, as primary crushers, reducing the ROM coal. Usually, these crushers will have teeth or raised forms on the face of the roll. (Roll crushers used for minerals and metal ores have smooth faced rolls.)

Working principle of Double roll crusher
 

A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.

Performance advantage of Double roll crusher
 

1. The crushing of the roller crusher is relatively large. When a large crushing ratio is required, the roller crusher can be equipped with an adjustable crushing bar under the two rollers.
2. The roller crusher has a simple structure and a modular structure, which can be installed separately or in combination.
3. It adopts combined crushing instead of impact and striking to break, and does not cause secondary crushing, so the over-grinding rate is extremely low.
