Double-roller Crusher/stone Making Machine/2-roller Crusher

We are offering double-roller crusher/stone making machine/2-roller crusher.introduction to 2-roller crusher
2-roller crusher(toothed roller crusher) bite material into crushing area through roller friction, material was crushed by squeezing and fracturing of machine. When it is used in coarse crushing or crushing ratio increases, roller surface are usual teeth or groove in order to increase fracturing effect. Crushing machine from huashengming use high manganese steel casting roller surface which is through heat treatment.
working principle of 2-roller 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. 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.
features of 2-roller crusher
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. Coal is probably the largest user of roll crusher currently. Coal plants will use roll crushers, either single roller or double roller. Usually, this crusher will have teeth or raised forms on the face of the roll. (double teeth roller crusher used for minerals and metal ores have smooth faced rolls.)
4. Besides, this roller is easy to operate, low in consumption, stable in running and simple in fabrication.
5. It is stable operation, easy maintenance, low cost, output size adjustable. .
