A crusher is an industrial machine designed to break down large materials like stones, rocks, or ores into smaller, manageable pieces. These machines play a key role in various sectors, particularly in construction and mining.

Purpose:
Crushers convert raw materials into aggregates, gravel, or sand suitable for building and road construction. They are also useful for recycling old materials like concrete or asphalt.

How it Works:
Crushing is performed through mechanical systems such as jaw, impact, or cone crushers. Once the material is crushed, it passes through vibrating screens that separate it into different sizes. The type of crusher and screen depends on the material hardness and final product requirement.

Common Uses:

  • Quarries

  • Road construction

  • Concrete and asphalt plants

  • Mining sites

  • Waste recycling facilities

What is a Mobile Crusher, What is its Purpose, How Does it Work, and Where is it Used?

A mobile crusher is a portable crushing and screening system that can be moved directly to the worksite. Its compact and mobile structure makes it ideal for short-term projects.

Purpose:
It performs material crushing and sorting directly on-site, reducing transport costs and processing time. It's widely used in recycling and small mining operations.

How it Works:
It consists of a crusher, motor, screen, and conveyors all mounted on a chassis. Usually powered by a diesel engine, it is quick to install. The material is fed into the crusher, then separated by screens into different sizes.

Applications:

  • Temporary construction sites

  • Road maintenance

  • Recycling operations

  • Small-to-medium mining areas

What is a Stationary Crusher, What is its Purpose, How Does it Work, and Where is it Used?

Stationary crushers are permanent installations designed for high-volume, long-term production. These are suitable for large industrial operations.

Purpose:
They enable continuous, large-scale processing of stone or ore. They are cost-efficient in the long run due to their high production capacity.

How it Works:
Set up on a fixed foundation, these plants use multiple crushers and screens. Material is fed through a feeder, crushed, screened, and then transported for storage or further processing.

Uses Include:

  • Large-scale quarrying

  • Mining industries

  • Infrastructure projects

  • Industrial aggregate production

Differences Between Mobile and Stationary Crushers

Mobile crushers offer flexibility, are easy to move, and require minimal setup time. In contrast, stationary crushers are more powerful, designed for long-term use, and provide higher productivity.

In Summary:

  • Mobile: Portable, fast setup, cost-effective for short-term use

  • Stationary: High capacity, long-term investment, more space and infrastructure needed

What is a Coal Crushing and Screening Plant, Its Purpose, How it Works, and Where it is Used?

A coal crushing and screening plant prepares raw coal by reducing its size and sorting it for different industrial uses.

Purpose:
It improves coal usability for transport, combustion, or processing. It also helps in removing oversized or unusable materials.

How it Works:
Coal is first crushed into smaller fragments, then passed through screens to classify it based on size. The system can be automated for efficient operation.

Applications:

  • Thermal power plants

  • Steel factories

  • Cement production

  • Industrial heating systems
