Coal Preparation Plant Conveyor

A coal preparation plant is a raw coal production line to get clean coal and remove coal gangue. In a coal preparation plant (CPP), belt conveyors play a crucial role in transporting coal and other materials throughout the various stages of the coal processing and handling system. The primary objective of a CPP is to process raw coal to meet quality specifications and prepare it for transportation.

Properly designed and maintained conveyor systems contribute to the continuous flow of materials, ensuring that the coal meets quality specifications for various industrial applications.

Raw Coal Handling ystem

• Belt Conveyor from Mine to Plant:
  Raw coal is transported from the mining site to the coal preparation plant using belt conveyors. These conveyors can cover short to long distances, depending on the location of the mine.
• Receiving Hoppers:
  At the plant, raw coal is often deposited into receiving hoppers, and belt conveyors facilitate the transfer of coal from these hoppers to the processing equipment.

Coal Crushing and Screening

• Conveyor to Crushing Unit:
  Raw coal is fed into crushers to reduce its size. Belt conveyors transport the crushed coal to the sizing equipment.
• Belt Conveyor to Screens:
  After crushing, the coal may be sent to vibrating screens for further sizing. Belt conveyors move the sized coal to the next stage of processing.
• Conveyor to Screens and Cyclones:
  Screens and cyclones are used to separate coal particles based on size and density. Belt conveyors are employed to transport coal to and from these screening and classification units.

Washing and Cleaning

• Belt Conveyor to Washing Units:
  Coal that requires washing to remove impurities is conveyed to washing units using belt conveyors.
• Belt Conveyor to Cyclones:
  In some cases, heavy media cyclones are used for coal separation based on density. Belt conveyors transport the coal to and from the cyclone units.
• Washed Coal Conveyance:
  After the washing process, the cleaned coal is transported to subsequent processing stages or storage using belt conveyors.

Dewatering and Final Product Handling

• Belt Conveyor to Dewatering Screens:
  Dewatering screens are used to remove excess water from the coal. Belt conveyors transport the dewatered coal to the next processing stage.
• Conveyor for Final Product:
  The final clean coal product is transported via belt conveyors to stockpiles or directly loaded onto trains or trucks for transportation to end-users.
