An Aggregate Crushing, Washing, and Screening Plant is an industrial facility designed to process natural stones and rocks into various sizes of clean, classified aggregates. It consists of machinery that crushes large rocks, washes the resulting material to remove dirt and impurities, and sorts it into predefined sizes using screens.

These plants are typically found in:

  • Quarries

  • Mining sites

  • Construction project areas

 WHAT IS ITS PURPOSE?

The main objective is to produce high-quality aggregates used in:

  • Concrete and asphalt production

  • Road base and subbase layers

  • Drainage and water filtration systems

  • Railway ballast

  • Structural foundations

 HOW DOES IT WORK?

1. Crushing Section

Large boulders are fed into crushers (jaw, cone, or impact crushers), where they are broken down into smaller, manageable pieces.

2. Washing Section

The crushed material is passed through log washers, hydrocyclones, and screw washers to eliminate:

  • Dust

  • Clay

  • Silt

  • Organic matter

Washing ensures the final product meets concrete or asphalt quality standards.

3. Screening Section

The washed aggregates are transported to vibrating screens that sort the material into various sizes (e.g., 0–4 mm, 4–12 mm, 12–25 mm, etc.).

4. Stockpiling and Dispatch

The sorted aggregates are sent via conveyors to designated storage piles and then loaded into trucks for delivery.

 WHERE IS IT USED?

  • Concrete batching plants

  • Asphalt production plants

  • Large-scale civil engineering projects

  • Highway and railway construction

  • Dams, tunnels, and bridges

  • Industrial prefab production

  • Open-pit mining operations
