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.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Rolls During the crushing operation, the two rolls rotate toward each other, resulting in crushing. The feed particle size determines the type of rollers used. Rollers with teeth are able to grip large particles, making it possible to crush blocks of considerable size in rolls of moderate diameter.

Crushing Rolls. Consist of two or more cylindrical roll that rotate between each other. Mainly force in reduction size compression; Differential speed is maintained to exert shearing forces on the particle. Roller surface smooth or can carry corrugation, breaker bars or teeth which can increase friction and facilitating the trapping of particle

Usually, roll crusher can be divided into three models according to the number of rolls: single roll crusher, double roll crusher and multi-roller crusher. Double roll crusher: The two rolls rotate in opposite directions, and the ore enters between the two rolls. Due to the frictional force, the ore is brought into the crushing space between

It will take larger than a 40-in. diameter roll crusher. A better solution would be to use a larger jaw crusher set at 1½ in., then a roll crusher from the Roll Crusher capacity Table above could be used. If the output of this crushing process should have less material of the +1-in. size, the larger crusher could be operated with a closed circuit.

Oct 18, 2015· Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the Rolls. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the

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. Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines.
