A crusher is a heavy-duty industrial machine used to break stones, rocks, or ore into aggregates for construction and infrastructure.

Operation Principle:
Material is fed via a feeder into jaw, cone, or impact crushers. Mechanical forces break down large pieces which are then sized by vibrating screens and transported via conveyors.

Applications:

  • Concrete and asphalt production

  • Road, bridge, tunnel construction

  • Dam, port, airport infrastructure

  • Mining ore processing

  • Recycling of construction debris

Mobile Crusher

A mobile crusher integrates crushing and screening systems onto a wheeled or tracked platform.

Operation Principle:
Powered by diesel or electricity, feed material enters the bunker, moves to crushers, and then to integrated screens. Crushed material can be loaded directly onto trucks.

Applications:

  • Temporary construction and demolition sites

  • Mountainous or difficult-to-access regions

  • On-site mining/quarry operations

  • Road/rail maintenance and repair

Fixed Crusher

A fixed crusher is a permanently installed industrial crushing facility with high continuous production capacity.

Operation Principle:
Raw material from trucks enters primary crushers, followed by secondary crushers. Results are screened and separated before conveyor deposition. Automation streamlines the process.

Applications:

  • Major infrastructure projects

  • Concrete and asphalt plants

  • Industrial mining complexes

  • Port and airport developments

Differences Between Mobile and Fixed Crushers

  • Mobility: Mobile units are portable; fixed units are stationary.

  • Setup Time: Mobile deploys quickly; fixed requires weeks of construction.

  • Capacity: Fixed plants handle higher tonnage.

  • Cost: Mobile involves greater upfront cost but lower logistics expenses. Fixed is more economical long-term.

  • Flexibility: Mobile can relocate; fixed remains at one site.

River Sand Washing and Screening Plant

Function and Definition:
A facility designed to clean, classify, and dewater river-extracted sand into usable aggregate for construction.

Purpose:
Removes silt, clay, and fine particles to produce construction-grade, washed sand.

Operation Principle:
Sand enters a hopper, then passes through pressure water jets to wash off impurities. The washed sand goes through screens to classify sizes, and conveyors transport the cleaned product to storage or drying systems.

Applications:

  • Concrete and mortar production

  • Road and subgrade fill

  • Foundation and infrastructure projects

  • Landscaping and aquatic applications

  • Prefabricated concrete block production
