Technical transformation practice of double-channel fine-screen in Tangkou Coal Mine
Combined with the reality of Tangkou coal mine coal preparation plant production,in view of the problems of the high recovery pressure of the sieve,the unstable operation of the magnetic separation machine,and the excessive ash content of the crude refined coal products caused by the poor mud removal effect of the downstream high-frequency sieve,using double channel sieve on the original temperature removal,After the production,the efficient recovery of the medium and the recovery link are realized,the stable operation of the system is realized,and the classification index of crude cleaned coal ash is controlled.The consumption index of crude coal sludge system was reduced by 0.2 kg/t,the yield of total cleaned coal was increased by 1.74%,and the economic benefit was significant.
