A crusher is a machine designed to reduce large rocks, ores, or construction waste into smaller pieces. It is used in aggregate production (sand, gravel), recycling projects, or mining to process raw materials into manageable sizes.

2. What is a Mobile Crusher?

A mobile crusher is mounted on a wheeled or tracked chassis, making it portable. Unlike stationary crushing plants, it can be easily transported to different project sites for on-site crushing. Mobile crushers can be equipped with various crushing mechanisms, such as jaw crushers, impact crushers, cone crushers, or vertical shaft impactors (VSI).

3. How Does It Work?

  1. Feeding: Material is loaded into the hopper using an excavator or loader.

  2. Crushing: The material is transferred to the crushing unit. For example, in a jaw crusher, it is compressed between fixed and movable jaw plates.

  3. Screening: Crushed material is sorted by size using vibrating screens.

  4. Conveying: Screened products are transported via conveyor belts to stockpiles or directly to the site.

4. Purpose

  • Aggregate Production: Produces sand and gravel for roads, concrete, or asphalt.

  • Recycling: Converts construction waste (concrete, bricks) into reusable materials.

  • Mining: Reduces ores to processable sizes.

5. Applications

  • Mining Industry: Gold, copper, or coal mines.

  • Construction Projects: Highways, dams, or residential buildings.

  • Waste Management: Recycling urban demolition debris.
