A mobile crusher is a portable crushing and screening plant used to process rocks, minerals, and construction debris. Unlike stationary plants, mobile crushers offer high mobility and flexibility, making them ideal for construction, mining, infrastructure projects, and recycling applications.

Mobile crushers are usually mounted on wheeled or tracked systems, allowing them to be easily transported between job sites.

Stages of Mobile Crushing Process

Mobile crushers perform step-by-step crushing processes to produce aggregates of different sizes. The stages are as follows:

1. Raw Material Feeding

Materials such as stones, minerals, or concrete are loaded into the feeding hopper using loaders or excavators. Vibrating feeders regulate the material flow to the crusher.

2. Primary Crushing

Large rocks or minerals are initially crushed in the primary crusher. Commonly used crushers:

  • Jaw Crushers: Used for hard and large rocks.
  • Impact Crushers: Suitable for medium-hard materials.

3. Secondary Crushing

The crushed material is further reduced in size using secondary crushers, such as:

  • Cone Crushers: Best for breaking hard rocks into smaller pieces.
  • Secondary Impact Crushers: Suitable for softer or medium-hard materials.

4. Screening and Classification

Crushed material is separated into different sizes using vibrating screens. The aggregates are classified according to the required grain size.

5. Recycling and Washing (Optional)

For recycling applications, mobile crushers may include magnetic separators or washing units to clean materials.

6. Stockpiling and Transportation

Finally, the processed materials are stored via conveyor belts or prepared for transportation.
