A crusher is a heavy-duty industrial machine used to reduce rocks, stone, or ore into aggregate sizes for construction and infrastructure projects.

Operation Principle:
Material flows from a feeder into the crusher (jaw, cone, or impact). After mechanical crushing, material is sieved for size consistency and transferred via conveyors to stockpiles.

Applications:

  • Production of concrete, asphalt, and fill material

  • Infrastructure works: roads, bridges, tunnels

  • Dam, port, and airport construction

  • Mining ore processing

  • Construction waste recycling

2. Mobile Crusher

A mobile crusher integrates crushing and screening on a transportable chassis, enabling immediate on-site operation.

Operation Principle:
Powered by diesel or electric engines, material is fed into the machine, crushed, screened, and then directly loaded onto trucks. Setup time is minimal.

Applications:

  • Temporary construction, demolition, and recycling

  • Remote or difficult-to-access areas

  • On-site quarry and mine operations

  • Maintenance and repair work

3. Fixed Crusher

A fixed crusher is a stationary plant established for large-scale, long-term aggregate production.

Operation Principle:
Trucks deliver material to the primary crusher, followed by secondary crushing stages. Vibrating screens sort outgoing product sizes; conveyors manage material flow. Automation optimizes throughput.

Applications:

  • Mega infrastructure projects

  • Concrete and asphalt plants

  • Industrial-scale mining

  • Bulk material stock preparation

4. Differences Between Mobile and Fixed Crushers

  • Mobility: Mobile units can be relocated; fixed units are stationary.

  • Commissioning Time: Mobile is operational within minutes; fixed requires weeks to install.

  • Throughput: Fixed plants handle higher daily tonnage.

  • Investment Cost: Mobile costs more upfront but saves transport; fixed is more cost-effective over time.

  • Operational Flexibility: Mobile units shift between sites; fixed systems serve a single location.

5. Marble Crushing and Screening Plant

Definition and Purpose:
Transforms quarried marble into specified granule sizes for decorative and structural applications.

Operational Sequence:

  • Raw marble is fed into a crusher via bunker or loader.

  • Primary crushing uses jaw or cone crushers.

  • Secondary crushers reduce marble to precise aggregate sizes.

  • Vibrating screens sort the crushed marble by size.

  • Conveyors direct sorted product to storage or direct use.

Applications:

  • Customized marble aggregate for cladding, flooring, landscaping

  • Interior and exterior finishes

  • Landscaping and mosaic applications

  • Fillers in cement, ceramics, and construction materials
