With the increase of pressure of raw coal into washing in coal preparation plant, coal sorting has become an important link. Aiming at the problems of insufficient processing capacity, low sorting efficiency and poor iron filings recovery rate of traditional raw coal sorting equipment, we have achieved good results by developing intelligent self-control two-stage combination raw coal sorting device and conducting experimental research in coal preparation plant. The results show that the intelligent self-control raw coal sorting device has significant improvements and advantages in all technical indexes, the equipment processing capacity is increased by 12.2%, the sorting efficiency is increased by 10.6%, the energy consumption is reduced by 6.7%, and the iron filings recovery rate is increased by 13.4%. It provides a sustainable, cost-effective solution for the coal industry.
