Crushing and screening plants are facilities designed to break large rocks, ores, and minerals into smaller sizes to be used in various industries such as construction, infrastructure, cement, and asphalt production.

2. Production Stages

A typical crushing and screening plant consists of the following stages:

2.1 Feeding

Large rocks or raw materials are transported to the crushing plant via trucks or feeders to ensure even distribution.

2.2 Primary Crushing

The raw material is initially reduced in size using primary crushers, such as:

  • Jaw Crushers: Used for hard and abrasive materials.
  • Impact Crushers: Suitable for medium-hard materials.
  • Gyratory Crushers: Ideal for high-capacity crushing.

2.3 Secondary Crushing

The crushed material is further reduced using secondary crushers, such as:

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

2.4 Tertiary Crushing

This stage ensures that the material is crushed into smaller sizes using:

  • Tertiary Impact Crushers
  • Vertical Shaft Impact Crushers (VSI)

2.5 Screening and Classification

Crushed materials are classified into different sizes using vibrating screens.

2.6 Washing and Cleaning (Optional)

Some plants include washing processes to remove dust and impurities.

2.7 Stockpiling and Transportation

Finally, the processed materials are transported via conveyor belts for storage or direct shipment.
