Standard-Duty Quad Roll Crushers are the lightest-duty Quad Roll Crusher and are designed to perform two-stage reduction on soft materials such as clean coal, salt, lime, coke, glass, etc. This model is powered by a single motor and features an inter-stage V-belt drive between the primary and secondary stages of crushing.
The floating roll enables the crusher to release tramp metal and adjust the gap by the hydraulic supported gap setting system. Adjustment of the gap The hydraulic system allows one roll to react to overload incidents by retracting and letting tramp metal or overloading material pass through the gap.
Roller crusher is widely used in solid and block material pulverizing. Roll gap between the rollers is usually adjusted to satisfy the particle size of output material. In order to realize convenient adjustment, a roll gap control scheme based on electro-hydraulic technology is designed and optimized.
It is at this point where a Double Roll Crusher must be used instead of a Sizer. The design of the Double Roll Crusher allows for a finer adjustment and therefore a finer product size. Cost. With the design differences also comes cost differences. The Double Roll Crusher is the more cost-effective option of the two.
Eccentric Roll Crusher ERC® ... Our single-step roller crusher consists of two rollers with cast bosses. One of the roller shafts is adjustable while the other has a fixed position, supplied by a flywheel. ... The motor power is transmitted through a gear drive and two cardan shafts allow adjustment of the space between the rollers. Both ...
Otte observed that the operational density of roll crushers is low (0.25–0.6 t/m 3). 6.5. Power Consumption of Roll Crushers. Within the same reduction ratio the power consumption of roll crushers varies widely. The power required could be expressed by the general equation (6.8) P = capacity × reduction ratio × work index

The rolls provide toothed patterns suited to the feed material. Single Roll Crushers generally handle larger feed sizes at higher reduction ratios in higher capacities. These machines are also great as lump breakers. Double Roll Crushers. Double roll crushers reduce primarily through compression, although toothed rolls provide some shear.
