A mobile crusher and screen is a portable system designed to crush and screen rocks, minerals, or construction waste into aggregates (sand, gravel, crushed stone). Mounted on wheels or tracks, these units eliminate the need for fixed installation and can be rapidly deployed to various sites. The crusher reduces large materials, while the vibrating screen classifies the crushed material by size.

Purpose

  1. Material Crushing: Reduces large rocks or concrete waste to desired sizes using jaw, impact, or cone crushers.

  2. Classification: Vibrating screens sort crushed materials by grain size (e.g., 0-5 mm sand, 5-20 mm gravel).

  3. Mobility: Processes materials on-site, reducing transportation costs.

  4. Recycling: Converts construction debris or mining waste into reusable materials.

How Does It Work?

  1. Transport & Setup: The plant is moved to the site via truck or self-propelled chassis and stabilized using hydraulic legs or tracks.

  2. Feeding: Raw material (rocks, concrete, ores) is loaded into the crusher via an excavator or feeder.

  3. Crushing Stages:

    • Primary Crushing (Jaw Crusher): Reduces material from ~1 meter to 10-20 cm.

    • Secondary Crushing (Impact/Cone Crusher): Further crushes to 2-5 cm.

    • Tertiary Crushing (Fine Crusher): Produces fine aggregates (0.5-2 cm).

  4. Screening: Vibrating screens classify materials into specific sizes.

  5. Storage/Transport: Sorted aggregates are conveyed to stockpiles or trucks.

Applications

  • Construction: Concrete production, road base layers.

  • Mining: Pre-processing of gold, copper, or coal ores.

  • Quarries: Natural stone processing for aggregate production.

  • Recycling: Reusing concrete, asphalt, or brick waste.

  • Disaster Recovery: Recycling post-earthquake or flood debris.
