How does the crusher machine work? A double toothed crusher with less volume is composed of two toothed rollers which is installed in parallel and rotates in opposite directions. The two-toothed rollers adopt non-meshing and non-constant speed operation to strengthen the degree of occlusion, which ideally prevents the material from slipping thus improving the crushin

Other methods of compensating for roll deformation include continual varying crown (CVC), pair cross rolling, and work roll bending. CVC was developed by SMS-Siemag AG and involves grinding a third order polynomial curve into the work rolls and then shifting the work rolls laterally, equally, and opposite to each other.

Types of crusher depend on the feeding method. These are- Primary crusher, Secondary crusher and Tertiary crusher. The primary crusher is only for the breaking of large stones into pieces (this means primary crusher is not for the aggregate size material.). Examples of primary crushers are jaw crusher; hammer mill crusher and gyratory crusher.

Double roll crusher (also called twin roll crusher) is composed of two cylindrical rollers as the main working mechanism (Figure 1). When working, the two round rollers rotate in opposite directions, and the material (ore) is crushed by the friction between the rollers, which rolls the material into the crushing cavity formed by the two rollers.

All three roll crusher types have identical working principle, with only few small differences. It is very important to have the right type of roll crusher, because once a material enters a roll crusher and can not be crushed, the roll crusher might get some serious damages.

The drive is assembled on a base frame, which is connected with the roll crusher. The floating roll drive, also supported in pivoting mode, is connected with the floating roll rocker arm by a coupling rod. This ensures that a constant drive belt tension exists during the retraction movement of the floating roll, and during gap adjustment.
