A fixed crushing and screening plant is a stationary system used in quarries, mining, and construction industries to break down large rocks and ores into smaller pieces and classify them using screens. It is commonly used for processing hard stones, limestone, basalt, dolomite, granite, and ores.

Working Principle:

Fixed crushing and screening plants consist of several key components, and the process includes the following steps:

  1. Feeding Unit: Raw material is introduced into the plant via a hopper or vibrating feeder.
  2. Primary Crusher: Large rocks and stones are initially broken down using a jaw crusher or impact crusher.
  3. Secondary Crusher: The reduced material is further processed using a cone crusher or secondary impact crusher.
  4. Tertiary Crusher (Optional): If finer material is needed, a tertiary impact crusher is used.
  5. Screening Unit: Crushed material is classified into different sizes using vibrating screens.
  6. Belt Conveyors: Processed material is transported to storage areas or directly used for production.

Advantages:

  • High Capacity and Efficiency: Capable of processing large volumes of material.
  • Quality and Homogeneous Output: Screening ensures the desired size of material is obtained.
  • Low Operating Costs: Since it is a stationary system, maintenance and fuel costs are lower compared to mobile plants.
  • Environmentally Friendly: With fewer moving parts, it generates less noise and dust emissions.

These plants are ideal for large-scale projects and are suitable for businesses that require long-term production.
