Big news! Recently, Shenzhou IDS intelligent dry separator in the Gaoyang Coal Mine of Shanxi Coking Coal Group created another legendary “excellent performance”: after preparation, the sampling rate of gangue with coal was “0”, setting a new record for preparation accuracy in the field of intelligent dry preparation technology.




Project overview

Gaoyang Coal Mine belongs to Shanxi Fenxi Mining (Group) Co., LTD, 200-50mm large coal is originally discharged by vibro-assisted jigging, due to the backward discharge process, the coal carrying rate of gangue in the stone is 5-8%. In April 2023, Gaoyang Coal Mine purchased two IDS-2000A intelligent dry separators from Tangshan Shenzhou Machinery Group, which replaced the original vibro-assisted jigging sorting system. After the equipment was put into use, the hourly selection amount could reach more than 400 tons.


Selection index

The coal rate of gangue: the average is less than 0.5%, the lowest as 0, more than 4000 tons of gangue can be discharged every day, reducing the loss of clean coal 200-300 tons. After the operation of Shenzhou intelligent dry selection system, the cost has been greatly reduced, and good economic benefits have been created for coal mines. 


Intelligent dry separator

Shenzhou intelligent dry separator can be used for 25-100mm and 50-300mm particle size coal preparation. It can achieve intelligent identification of gangue, intelligent blowing, and the whole preparation process without manual labor. It is featured on high preparation accuracy, high degree of intelligence, simple process flow, etc., and brings great value to preparation applications such as pre-discharge of gangue from coking coal, thermal coal quality improvement, underground “picking-preparation-charging” integration, coal disposal, and dirty mixed coal recycling. Currently, this model has obtained radioactive isotope and radiation devices exemption.

Shenzhou's intelligent dry preparation technology, started up in 2008, has now been successfully applied in major coal-producing provinces and regions such as Shanxi, Inner Mongolia, Heilongjiang, Ningxia, Guizhou, Xinjiang, and Hebei. Average measured application data: the rate of gangue with coal is less than 1%, and the gangue discharge rate is greater than 95%. 

Gangue with coal is "0"! Shanxi Coking Coal Group's IDS intelligent gangue sorting index refresh industry record!
