What is a double-roll crusher?

The double-roll crusher is a mining machinery and equipment, mainly used to crush ore, rock, and other materials.

The double-roll crusher squeezes and crushes the material through two rollers rotating in opposite directions (one moving roller and one fixed roller), thereby achieving the crushing effect.

Features and advantages of double roll crusher

1. Small size and large crushing ratio: Double-roll crusher has the characteristics of small size and large crushing ratio, which can usually reach 5-8.

2. Low noise and simple structure: The equipment has low operating noise and simple structure, which is easy to maintain and operate.

3. Good crushing effect: The particle size of the crushed material is uniform, the over-crushing rate is low, and the quality of the crushed material is good.

4. Safe and reliable: The equipment has an overload protection function. When an overload occurs, it can automatically stop for protection to ensure the safety of the equipment.

Structure and composition of the double-roll crusher

Frame: The supporting structure of the double-roll crusher, usually welded from steel plates, with high strength and stability.

Roller: The core component, usually made of cast iron or steel plates, the surface can be processed into different shapes (such as raised gears or cams) as needed to increase the friction between the material and the roller and improve the crushing effect. The diameter and width of the roller can be selected according to different crushing requirements.

Transmission: It consists of motors, reducers, couplings and other parts to provide power to the roller so that it can rotate and crush materials.

Feed port and discharge port: Located at the top and bottom of the frame respectively, used for the entry and exit of materials. The size and shape of the feed port and discharge port can be designed according to different materials.

What Is The Working Principle Of The Double Roller Crusher?

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.

Application fields of double roll crusher

Double roll crusher is widely used in coal, metallurgy, mining, chemical industry, building materials and other industries, especially suitable for crushing raw coal (including gangue) in large coal mines or coal preparation plants. In addition, it is also widely used in construction, water conservancy projects, highway and railway construction, bridge construction and other fields, such as preparation of concrete aggregates and preparation of various specifications of stones.
