Descriptions:

The double roller crusher is a popular choice of soft to medium-hard rocks and ores in the mining industry, designed to crush coal in large coal mines and coal preparation plant. 

What Is a Double Roller Crusher?

Double roller crusher is a type of crusher that features two parallel and toothed rollers rotating in opposite directions. It is applied to crush various medium hardness rocks such as limestone, slag, coal, clay, scoria, etc. It is also capable of handling wet, sticky materials.

Twin roller crusher machine crushes the materials usually for primary or secondary crushing applications. The sensor as an overload protection device can ensure the double roller crusher safe and reliable.

What Is Double Roller Crusher Used For?

CFTC double roller crusher is a type of highly efficient crushing machine, used in various industries, especially in large coal preparation plants.

• Coal Mining

• Aggregate

• Metallurgy

• Building Materials

• Refractory Materials

• Cement Processing

• Electric Power

• Ceramics and Glass

• Expressway

What Are the Features of Double Roller Crusher?

1. Strong applicability, capable of crushing dry, wet, and, sticky materials.

2. Dual rollers allow for efficient crushing of materials by exerting compressive force from both sides.

3. High crushing ratio improving the capacity and quality of the final products.

4. Crushing the materials absolutely with an advanced hydraulic control system.

5. Overload protection device ensuring safe and reliable operation.

6. Big discharged open, material discharged easily, and big capacity.

What Are the Parts of Double Roller Crusher?

A double roller crusher typically consists of the following main parts: fixed roller, moveable roller, machine frame, screw, turning direction, compression spring, oil cylinders, etc. The double roller crusher is relatively easy to install and operate.

Some of the vulnerable parts of a double roller crusher mainly include two rollers, roller shafts, and triangular belt. It is simple to change the tooth plate and tooth rings. By monitoring the vulnerable parts, the service life of the roller crusher machine can be maximized.

How Does Double Roller Crusher Work?

The working principle of a double roller crusher is mainly using the wear-resistant toothed roller to break the raw material through high-speed rotation.

The raw material enters the roller crusher and is crushed thoroughly by the rotating rollers. The two rollers force the particles between their surface into the ever smaller gap area, and the particles fracture from the compressive forces presented by the rotating rollers.
