Features

High crushing efficiency
The double roll crusher adopts the double-roller extrusion crushing principle. The crushing cavity is deep and has no dead zone. The materials can be fully and effectively crushed in the crushing cavity, so it has high crushing efficiency.

Adaptable
The double roll crusher is suitable for various environments and usage scenarios and can operate stably whether indoors or outdoors. In addition, it can handle wet and dry materials without being affected by the moisture content of the materials.

Controllable granularity
The roller gap of the double roll crusher is adjustable, and the discharge particle size can be adjusted as needed to meet different production needs.

Energy saving and environmental protection
During the crushing process of the roller crusher, there is little dust pollution and low noise, which complies with environmental protection standards. In addition, its low energy consumption saves users energy costs.

Sufficient Supply of Spare Parts, Worry-free Operation
Dingbo is the manufacturer, we take responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.

Working Principle

The double-roll crusher performs crushing operations through rollers. The material enters between the rollers from the feed port and is crushed by extrusion. When the roller seats rotate towards each other, the material is rolled between the two rollers under the action of the friction force on the roller surface and its own gravity and is subjected to extrusion, impact, shearing, and kneading from the rollers. When the action of these forces is greater than the aggregation force between the crystal lattices of the object, the material breaks into small pieces and the purpose of crushing is achieved.
