Gaoyang Coal Mine belongs to Shanxi Fenxi Mining (Group) Co., Ltd., 200-50mm large coal originally used dynamic screen jigging for gangue discharge, due to the backward gangue discharge process, the gangue coal rate is 5-8%. In April 2023, Gaoyang Coal Mine purchased two IDS-2000A intelligent dry separators from Tangshan Shenzhou Machinery Group to replace the original dynamic screen jigging and sorting system. After the equipment is put into use, the hourly input volume reaches more than 400 tons.
Sorting indicators
Gangue coal rate: less than 0.5% on average, as low as 0, more than 4,000 tons of gangue can be discharged per day, reducing the loss of refined coal by 200-300 tons. After the Shenzhou intelligent dry coal preparation system was put into operation, the cost was greatly reduced, creating good economic benefits for the coal mine.
On November 9, 2023, the coal rate of the sampled gangue of the selected product was "0", which refreshed the record of sorting accuracy index in the field of intelligent dry separation technology.
