摘要

为检测新一代S-FHMC型超级煤泥重介质旋流器的工艺效果,对其进行了两次中试及工业性试验;中试结果显示:分选0.25～0.10 mm粒级两次试验的可能偏差E为0.078 kg/L、0.074 kg/L,说明分选下限已达0.1 mm;数量效率达到95%;处理能力提升60%以上;S-FHMC50型超级煤泥重介质旋流器在临涣选煤厂的工业性试验中,分选0.25～0.10 mm粒度可能偏差E值为0.075 kg/L,数量效率高达98.14%,处理能力480 m~3/h,较同直径的传统煤泥重介质旋流器提升70%以上。
        In order to test the process effect of the new generation of S-FHMC super heavy medium cyclone for slime,two pilot tests and one industrial test were carried out. The results of the pilot tests showed that for the 0. 25 ～ 0. 10 mm slime,the probable error values are 0. 078 kg/L,0. 074 kg/L separately for two pilot tests,indicating that the lower limit of separation for super heavy medium cyclone has reached 0. 1 mm. The organic efficiency has reached 95%. The capacity has increased by more than 60%. In the industrial test of SFHMC50 super heavy medium cyclone for slime in Linhuan Coal Preparation Plant, the probable error value of 0. 25 ～0. 10 mm is 0. 075 kg/L. The organic efficiency is up to98. 14%. The capacity is 480 m3/h. Compared with the capacity of traditional heavy medium cyclone for slime, the capacity of super heavy medium cyclone is increased by more than 70%with the same diameter.
