Crushed stone, commonly known as "gravel" or "aggregate", is a type of construction material produced by crushing large rocks (like granite, basalt, limestone) into specific sizes. It is screened to achieve uniformity and is a vital component in many civil engineering and infrastructure applications.

 WHAT IS CRUSHED STONE USED FOR?

Crushed stone serves as a structural base for many construction applications. It is widely used in:

  • Concrete production (as coarse aggregate)

  • Road construction (base and surface layers)

  • Railroad ballast

  • Drainage systems

  • Landscaping and gardening

  • Foundations and backfill

  • Industrial flooring and pavement applications

 HOW DOES CRUSHED STONE WORK?

Crushed stone acts as a stabilizing component. In concrete or asphalt mixes, it combines with binders like cement or bitumen to provide strength and durability. In railway construction, it stabilizes the track, provides drainage, and absorbs vibrations.

WHERE IS CRUSHED STONE USED?

  • Ready-mix concrete plants

  • Highway and road projects

  • Railways and metros

  • Drainage infrastructure

  • Retaining walls and foundation works

  • Landscaping and hardscaping

 WHAT IS A CRUSHED STONE PLANT?

A crushed stone plant is an industrial facility where large stones are mechanically processed into various aggregate sizes. These plants consist of feeders, crushers, screens, conveyors, and stockpile areas. Some advanced systems also include washing units.

 WHAT IS A CRUSHED STONE PLANT USED FOR?

The main function of a crushed stone plant is to produce aggregates for use in construction and infrastructure development. It supplies raw materials to concrete plants, asphalt facilities, and railway projects.

HOW DOES A CRUSHED STONE PLANT WORK?

  1. Feeding: Raw materials are loaded into a feeder.

  2. Crushing: Jaw, impact, or cone crushers reduce stone sizes.

  3. Screening: Vibrating screens separate materials into defined sizes.

  4. Stockpiling: Final products are conveyed to stock areas.

  5. Washing (optional): Dust and fine particles are removed for higher purity.

 WHERE IS A CRUSHED STONE PLANT USED?

  • Quarry operations

  • Concrete and asphalt producers

  • Railway construction material supply

  • Major infrastructure projects

  • Mobile or on-site installations for remote projects
