PRODUCT FEATURES
Product features
Roll diameters and widths are dictated by the feed size, product size, and capacity. The rule of thumb for the Double Roll Crusher’s ratio of reduction is 4:1.
Stable Performance
The simplified design gives these units excellent reliability and requires very little maintenance.
Quality Assurance

With a variety of roll surface designs, this crusher is capable of producing a much finer product.

Optimal Design
The crushers are designed with built-in tramp relief that allows for the passing of uncrushable objects while remaining in continuous operation and returning to the initial product setting.
Differentiated design

Since each machine is custom engineered, roll elements and tooth patterns are selected depending on each unique application.

APPLICATION
Application
Double Roll Crushers typically follow a primary or secondary crusher and are used for secondary and tertiary reduction of various minerals.
Applicable materials
Coal, clean coal, limestone, gypsum, trona, shale, bauxite, oil shale, coke, salt, lime, glass, kaolin, brick, shale, and wet, sticky feeds. They are one of the most widely used crushers in the mining industry and have numerous advantages.

Working principle
Working principle

The materials to be crushed fall from the feeding mouth to the space between the two rolls. After being squeezed and crushed, the final products will naturally fall. When there are too hard materials or materials that cannot be crushed, the rolls of the roller crusher will automatically withdraw under the effect of a hydraulic cylinder or spring to increase the gap between the rolls, and the too hard materials or the materials that cannot be crushed will fall. Thus protecting the machine from being damaged. There is a certain gap between the two rolls that rotate in the opposite direction, and the maximum discharging granularity of the final products can be controlled by changing this gap. A double roller crusher's the materials by relying on the two round rollers rotating in the opposite direction, and a four-roll crusher crushes the materials by relying on the two pairs of round rollers rotating in the opposite direction.
