450-1200 TPH Double Roller Crusher Soft Rock Crushing Simple Structure

Applicable Scope Of Double Roller Crusher

The Double Roller Crusher can be used in coal, electric power, cement, environmental protection and other industries, and the compressive strength of materials is less than 125-175MPa, such as raw coal, limestone and other brittle block materials.

Working Principle

Two Rotating Rollers: A roller crusher consists of two cylindrical rollers that rotate in opposite directions. The rollers are typically mounted on a sturdy frame and can be arranged in a parallel or staggered configuration.

Material Feed: The material to be crushed is fed into the top of the crusher between the two rollers. It can be fed by a conveyor belt, depending on the specific setup.

Crushing Action: As the rotating rollers move, they compress the material between them. The material is drawn into the gap between the rollers and is subjected to both compressive and shearing forces. The compressive force exerted by the rollers crushes the material, while the shearing force breaks it apart.

Size Reduction: The material is crushed and broken into smaller particles as it passes through the gap between the rollers. The size of the final crushed product is determined by the gap between the rollers, which can be adjusted to control the desired output size.

Discharge: Once the material is crushed to the desired size, it exits the crusher through the bottom discharge opening. The crushed material can then be further processed or conveyed for subsequent use or storage.

Optional Features: Some roller crushers may have additional features to enhance their performance or ease of operation. These can include adjustable gap settings to control the output size, a feeding mechanism to ensure a consistent flow of material, and safety devices to prevent damage due to overloading or tramp material.

Maintenance

1. Bearing

Crusher bearings bear the full load of the machine, so good lubrication has a great bearing life, which directly affects the service life of the machine and the operating rate, thus requiring the injection of lubricant must be clean, the seal must be good.

2. The newly installed wheel hoop is prone to loosening must be checked frequently.

3. Pay attention to the normal work of all parts of the Double Roller Crusher.

4. Pay attention to check the degree of wear and tear of easy-to-wear parts, always pay attention to the replacement of worn parts.

5. Put the active device of the bottom frame plane, should go out of dust and other things to avoid the machine can not crush the material when the active bearing can not move on the bottom frame, resulting in serious accidents.

6. The bearing oil temperature rises, should immediately stop to check the cause to eliminate.

7. If there is impact sound when the rotating gear is running, stop immediately to check and eliminate.
