Coal Preparation Technique with Heavy Medium Recovery System Jointly Applied to Lump Coal and Fine Coal

TANG Li-gang;CHEN Hui;LI Min;ZHANG Xin-long;Department of Mining and Design,Tiandi Science and Technology Company Limited;China Mining Industry International Engineering Design and Research Institute Company Limited;  
According to system complicated and high difficult management existed in the lump coal heavy medium separator and the fine coal heavy medium cyclone preparation technique,coal preparation technique was provided based on heavy medium recovery system jointly applied to lump coal and fine coal. The lump refuse and clean lump coal would both run into fine heavy medium removing system and with an adjustment of water refilling quantity and bypass flow quantity of qualified medium,an independent adjustment on the separation density of the lump coal and fine coal system could be realized. The technique was applied to the design and production of Xinyao Coal Preparation Plant. The results showed that ash content of the cleaned lump coal and cleaned fine coal both was 5% ~ 6%,moisture content was 12%and 15% individually and the separation system was stable in operation. Meanwhile,heavy medium removing screen of cleaned lump coal,heavy medium removing screen of lump refuses and dilute medium barrel were eliminated and the investment would be reduced. The coal preparation technique with heavy medium recovery system jointly applied to lump coal and fine coal could have good suitability to the steam coal separation and could provide basis to the promotion in the coking coal preparation plant.
