Background
Yongtai Energy Group Co., Ltd.: The only listed private enterprise in the coal sector, the intelligent dry separation system was publicly tendered and purchased in March 2025, and DRX intelligent mineral separation equipment won the bid.
Coal sorting plant requirements:
1. Production capacity
The screening system is designed to produce 800 t/h of raw coal, and the sorting system is designed to produce no less than 200 t/h.
2. Coal quality characteristics
The yield of 50-300 mm particle size in the raw coal is 25%, and the gangue content in the lump coal is 70-80%.
3. Modification process and requirements
An intelligent dry sorting system is proposed to replace the manual sorting system to process large lumps of raw coal larger than 50 mm. After screening, the raw coal above the screen enters the intelligent dry sorting machine, while the coal below the screen enters the fine coal transfer conveyor. After the sorting machine, a small vibrating screen is added for secondary recovery of coal adhering to the gangue surface. After screening, the gangue falls to the ground, and the clean coal after selection can be dropped to the ground via a flap control or transferred to the fine coal conveyor via a belt conveyor.
