A mobile crusher is a portable machine designed to crush and screen rocks, minerals, and recyclable materials. Unlike stationary crushing plants, mobile crushers can be easily relocated and quickly adapted to different projects. They are commonly used in construction, roadworks, mining, and recycling industries.

These machines are typically mounted on a tracked or wheeled chassis, making transportation between and within job sites effortless.

Mobile Crusher Working Process

Mobile crushers perform crushing and screening operations in sequential stages:

1. Material Feeding

Materials like rocks, minerals, or concrete are loaded into the feeding hopper using loaders or excavators. The vibrating feeder ensures a consistent material flow into the crusher.

2. Primary Crushing

Large rocks and stones undergo an initial reduction in size. Common primary crushers include:

  • Jaw Crushers: Suitable for high-hardness materials.
  • Impact Crushers: Used for softer and medium-hard materials.

3. Secondary Crushing

The material from the primary crusher is further reduced using secondary crushers, such as:

  • Cone Crushers: Best for hard and abrasive rocks.
  • Secondary Impact Crushers: Used for medium-hard materials.

4. Screening and Sizing

Crushed materials are sorted into different sizes using vibrating screens, ensuring proper classification based on grain size requirements.

5. Washing and Cleaning (Optional)

For recycling projects or dusty materials, mobile crushers can be equipped with washing units or magnetic separators.

6. Stockpiling and Transport

Finally, the processed material is conveyed to stockpiles or directly loaded for transportation.
