A crusher is an industrial machine used to reduce large rocks, stones, or ore materials into smaller, usable sizes. It is essential in construction, mining, road building, and recycling industries.

Purpose:
Crushers produce aggregate required for infrastructure projects like concrete, asphalt, and road base by breaking down large rocks.

How It Works:
Raw material is fed into crushers via a hopper. It is then crushed using mechanical force – compression, impact, or shear – and classified by vibrating screens into various sizes.

Usage Areas:

  • Highway and bridge construction

  • Dam projects

  • Concrete plants

  • Mining operations

  • Construction waste recycling

What Is a Mobile Crusher?

A mobile crusher is a compact, portable crushing unit mounted on a chassis or track. It can be transported from one site to another with ease.

Purpose:
Ideal for temporary construction projects or remote areas. Eliminates the need for fixed infrastructure.

Working Principle:
The unit integrates feeding, crushing, screening, and conveying systems. Material is processed on-site and can be immediately reused or transported.

Application Fields:

  • Roadworks in remote areas

  • Mining exploration sites

  • Urban demolition

  • Emergency repair operations

  • Temporary aggregate supply

What Is a Fixed Crusher?

A fixed crusher is a large-scale stationary plant designed to handle high volumes of material consistently over time.

Purpose:
Used for continuous, large-capacity aggregate production in fixed locations.

Working Process:
Includes a series of crushers, vibrating screens, and conveyors installed permanently on-site. Fully automated for efficiency.

Where It Is Used:

  • Mining sites

  • Dams and bridges

  • Large-scale concrete production

  • Industrial construction projects

Differences Between Mobile and Fixed Crushers

  • Mobility: Mobile units can be moved; fixed units remain stationary.

  • Setup Time: Mobile crushers are quicker to deploy; fixed plants require detailed site preparation.

  • Capacity: Fixed crushers generally offer higher throughput.

  • Flexibility: Mobile systems offer multi-site usability; fixed systems are dedicated.

  • Cost: Mobile systems may have higher initial cost but offer savings in logistics.

What Is a Mineral Grinding Plant?

A mineral grinding plant is an industrial facility that processes ore into fine particles to allow for further metallurgical treatment or material usage.

Purpose:
Fine grinding is necessary to liberate valuable minerals from ore for separation and purification.

How It Works:
Pre-crushed ore is fed into grinding mills like ball mills or vertical mills. The rotating action grinds the material into powder. Classifiers then separate particles by size.

Used In:

  • Precious metal mining (gold, copper, iron)

  • Cement manufacturing

  • Ceramic and glass industries

  • Coal processing

  • Chemical industry
