Introduction:
Hebi Coal & Electricity Co., Ltd. sought to modernize the outdated coal production system at their Third Mineshaft, initially established in 1957. The original system relied on screening and hand sorting, followed by crushing and mixing with screened slack coal before sending it to the coal preparation plant. To address inefficiencies and high Reject content, Hebi Coal & Electricity Co., Ltd. integrated advanced dry sorting technology from HPY Finlay.
Project Overview:
Location: Hebi Coal & Electricity Co., Ltd. – Third Mineshaft
Initial System: Screening and hand sorting, followed by crushing and mixing
Issue: High Reject content causing blockages and affecting production efficiency
Modernization Details:
Processing Capacity: 1.20 Mt/a
Processing Particle Size: Pre-reject Reject from 50-300mm raw coal
Machine Used: 1 FHG-1400-X Golden Coal Series dry coal sorting machine
Single Machine’s Processing Capacity: 115-160 t/h
Performance and Results:
System Processing Result:
Coal in Reject: <1%
Reject Discharge Rate: >95%
Benefits of the Renovation:
Improved Efficiency: The addition of the FHG-1400-X Golden Coal Series dry coal sorting machine has significantly enhanced the quality and efficiency of the coal preparation process.
Reduced Blockages: The advanced dry sorting technology effectively reduces Reject content, minimizing blockages in the mixing tank and cyclone.
Enhanced Production: The modernized system ensures stable production with high-quality coal output and efficient Reject rejection.
Conclusion:
The integration of HPY Finlay’s dry coal sorting machine into Hebi Coal & Electricity Co., Ltd.’s production system has successfully addressed the inefficiencies of the old system. By adopting state-of-the-art dry sorting technology, Hebi Coal & Electricity Co., Ltd. has improved its coal preparation process, ensuring higher efficiency and better coal quality.
