A mobile crusher is a portable crushing and screening plant used to crush rocks, minerals, or construction waste on-site. It is mounted on wheels or tracks, allowing it to be transported easily between locations.

2. What Is Its Function?

  • Crushing large rocks in quarries

  • Recycling concrete and asphalt from demolition projects

  • Reducing ore size in mining operations

  • Producing aggregate for road construction and infrastructure

3. How Does It Work?

  • Raw material is fed via a feeder bunker.

  • The material passes through a crusher (jaw, impact, or cone).

  • Crushed material is screened using vibrating screens.

  • Final product is discharged through conveyor belts.

4. Fields of Application

  • Quarrying

  • Road and infrastructure works

  • Demolition waste recycling

  • Mining and aggregate processing

5. What is a Stationary Crusher?

A stationary crusher is a fixed crushing and screening system installed at a specific site. It is used for high-volume, continuous production applications.

6. What Is Its Function?

  • Large-scale material processing

  • Continuous operation with high capacity

  • Used in industrial mining and major quarries

7. How Does It Work?

  • Raw material is delivered to the hopper by trucks or loaders.

  • Material passes through primary, secondary, and sometimes tertiary crushers.

  • Vibrating screens separate the final products by size.

  • Material is conveyed to stockpiles or loading zones.

8. Fields of Application

  • Industrial-scale mining

  • Large-scale quarries

  • Asphalt and concrete production plants

  • Mega infrastructure projects

9. Differences Between Mobile and Stationary Crushers

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

  • Setup Time: Mobile crushers are quickly deployed; stationary ones need more time.

  • Capacity: Stationary units often support higher production volumes.

  • Cost: Stationary units have higher upfront costs but are more efficient for long-term use.

  • Usage Scope: Mobile is ideal for small to mid-size jobs; stationary suits large, ongoing projects.

10. What is a Secondary Impact Crusher Blow Bar?

A blow bar is a wear part of the rotor in a secondary impact crusher, designed to break material by striking it with high-speed rotation.

Purpose

  • Achieves desired grain size in the second crushing stage

  • Breaks down previously crushed material into finer pieces

  • Increases impact efficiency

How It Works

  • The rotor spins at high speed.

  • Attached blow bars hit the material forcefully.

  • Material fractures upon impact and is broken down.

Applications

  • Quarries

  • Recycling plants

  • Mining operations

  • Asphalt and concrete production
