| Abstract: | the separation low limit of large diameter dense medium cyclone on the high side that result in high ash content in fine clean coal,and the separation upper limit of flotation column on the low side that leading to the lost of clean coal,which both reducing the clean coal yield.To stable the product index and increase the yield of clean coal,the paper researched the processing and recovery technology in No.2 branch of Taixi coal preparation plant. |
