Analysis of optimizing separation indexes of small clean coal based on the principle of optimal yield in second separation zone of Taixi coal preparation plant

To make good use of rare anthracite in Taixi and maximize economic benefit,improve quality of blended product,based on the principle of optimal yield,method of matching different small clean coal from different separation zone,was analyzed by calculation and then separation indexes were optimized in second separation zone of Taixi coal preparation plant. The results show that blended clean coal is increased by 0. 5%.
