Bluestone roller crusher: ideal for efficient crushing

In mining, metallurgy, building materials and other industries, crushing equipment is an indispensable and important tool.Among them, the roller crusher has its unique advantages and performs well when crushing hard materials such as bluestone.This article will introduce in detail the working principle, characteristics and application of bluestone roller crusher to help readers better understand this equipment.

1. The working principle of bluestone roller crusher

A counter-roller crusher, also known as a double-roller crusher, is a kind of crushing equipment that uses two opposite rotating rollers to crush materials.Its working principle is relatively simple: the material falls vertically into the crushing chamber from the upper part of the crusher, and is squeezed and broken by the strong pressure generated between the two rollers.Most of the broken material has become powdery, and a large number of cracks have been produced inside the remaining small granular material, thereby achieving the crushing effect.

2. The characteristics of bluestone roller crusher

Efficient crushing: The roller crusher has the advantages of small size, large crushing ratio (generally 5-8), low noise, simple structure, and easy maintenance.Its crushing capacity is large, and a limited-range hydraulic coupling is used between the motor and the reducer to prevent power overload, sensor overload protection, safe and reliable.
Uniform particle size: By adjusting the gap between the two rollers, the particle size of the discharge can be accurately controlled to ensure that the particle size of the broken material is uniform and the over-crushing rate is low.
Strong applicability: The roller crusher is suitable for a variety of materials, including bluestone, coal, iron ore, quartz stone, etc.Especially in the coal industry, the use of this machine to crush raw coal only needs to go through iron removal, impurity removal, and gangue removal, which can be directly broken, simplifying the coal preparation process and reducing investment and production costs.
Easy maintenance: the equipment is equipped with a dust-proof plate inside, which has good sealing performance, avoids the splashing of fine materials after crushing, has less dust and low working noise.At the same time, the roller surface is wear-resistant, has a long service life, small maintenance volume and low cost.

3. Application of bluestone to roller crusher

Bluestone roller crushers are widely used in mining, metallurgy, building materials, chemical industry, electric power and other industries.In cement, refractory materials, coal mines and other industries, it is mainly used for coarse and intermediate crushing of brittle bulk materials.Especially when dealing with hard materials such as bluestone, the roller crusher performs well and can efficiently crush bluestone into the required particle size.

In addition, bluestone roller crushers are also suitable for artificial sand making, mining fine crushing, crushing raw materials in the ceramic industry and other fields.Its strong crushing ability and precise particle size control make it have wide application prospects in these fields.

4. Maintenance and maintenance of bluestone roller crusher

In order to ensure the normal operation and extend the service life of the bluestone roller crusher, regular maintenance and maintenance are required.The following are some key maintenance and maintenance measures：

Strengthen iron removal work: Iron removal devices should be installed before the crusher to prevent non-broken objects (such as drill heads, etc.) from falling into the double rollers and damaging the crusher.
Regular inspection and adjustment: Regularly check the lubrication parts of the equipment, refuel on time, and keep the equipment in good lubrication condition.At the same time, according to the hardness and particle size changes of the material, adjust the spacing of the crushing rollers in a timely manner.
Deal with clogging faults in a timely manner: When the material clogs the crushing space, it should be stopped for treatment, and mining should not be carried out during operation.
Regular shutdown and maintenance: After the crusher is in operation for a long time, due to the large wear on the roller surface, the product particles will be too fine.At this time, it should be shut down for maintenance, adjust the ore discharge port or replace severely worn parts.
