Solutions & Process

Granite/Limestone Crushing Process

300-400TPH Granite Crushing Plant

Steps of the crushing plant

  • Unload the raw materials to the hopper.
  • Raw materials will flow evenly into vibrating feeder DN600*130, which feeds raw materials to jaw crusher PE-900*1200.
  • After crushing by jaw crusher PE-900*1200, the output from the jaw crusher goes to the first impact crusher PF1520 via belt conveyor B1200*25.
  • The output from impact crusher PF1520 goes to the first vibrating screen 2YD2470(screen mesh size 19mm, 25mm) via belt conveyors B1200*13& B1200*28.
  • After screening by the first vibrating screen 2YD2470, the +25mm materials return to the second impact crusher PF1320 via belt conveyor B1000*21.
  • The 19-25mm materials from the first vibrating screen 2YD2470 go to stockpile by the final product belt conveyor B800*20.
  • The 0-19mm materials from the first vibrating screen 2YD2470 go to the second vibrating screen 2YD2470(screen mesh size 6mm, 13mm) by belt conveyor B1000*23.
  • After screening by a second vibrating screen, can get 0-6mm, 6-13mm, and 13-19mm materials, will be sent to stockpiles by final product belt conveyors B800*20.

This 300-400TPH Granite crushing process is also fit for limestone crushing.
