Scene:
double roll crusher is specially used to process various materials with medium hardness, such as coal, limestone and slag. The equipment relies on two rollers rotating in opposite directions to carry out crushing operations and is widely used in mining, metallurgical production, chemical industry and other fields.
granite

Granite is a coarse-grained (phaneritic), intrusive igneous rock composed primarily of quartz, alkali feldspar, and plagioclase.

PropertyValue / Description
NameGranite
Density2.6 – 2.8 g/cm³
Mohs Hardness6 – 7 (high hardness, close to quartz at 7)
Compressive Strength100 – 300 MPa (some high-quality granites exceed 300 MPa)

Rollers: two parallel mounted rollers, the surface can be smooth or with teeth, usually made of high manganese steel or other wear-resistant materials.
Transmission device: including motor, reducer and coupling, driving the rollers to rotate.
Adjustment device: used to adjust the roller spacing and control the particle size of the output material.
Frame: supports all components to ensure stable operation of the equipment.
Safety device: such as overload protection to prevent equipment damage.

Processing materials of double-roll crusher

Double roll crusher in mining field

Double-roll crusher is widely used to crush ores, coal and other resources of various hardness, providing suitable particle size materials for subsequent smelting and processing.

Metallurgical industry

This equipment is often used to treat solid wastes such as slag and coke, realize the effective recycling of resources, and optimize the production process.

Chemical production

Double-roll crusher plays a key role in crushing various chemical raw materials, ensuring that the raw materials meet the ideal particle size requirements, which is convenient for subsequent chemical reactions and processing.

Building materials industry

It is often used to process raw materials such as limestone and gypsum, and provide standard fine crushed materials for the manufacture of cement, gypsum board and other products.

Simple and clear structural design: The components are tightly connected, making maintenance more convenient and quick.

High-efficiency crushing capacity: High crushing ratio can ensure that the particle size of the crushed material is more uniform and consistent, improving product quality.

Relatively low operating energy consumption: At the same time, high crushing efficiency helps to reduce production costs and improve economic benefits.

Flexible and adjustable particle size: The equipment has strong adaptability and can flexibly cope with a variety of materials with different hardness and properties to meet diversified production needs.
