摘　　要：新型高效圆形离心浮选机充分发挥了湍流射流及离心—重力力场的作用，使其在矿浆充气、气泡矿化、浮选槽内矿浆流动形式、给料方式等方面独具特色。消除了常规浮选机中矿浆在浮选槽内的内循环，取消刮泡机构，降低了能耗，减轻了维修量。操作简便、入料级比宽，易于集中控制。实验室研究和工业性运行实践表明，该机在合适的工况条件下，可获得较好的分选指标，对于烟煤其可燃体回收率可达９０％左右，处理量可通过改变相应结构控制，处理干煤泥量可达２８～３０ｔ／（ｈ·ｍ３）。适用于各类规模的选煤厂。The circular centrifugal flotation cell which is developed by Clean Coal Technology Institute of Heilongjiang Mining Institute is a new type and equipment for fine coal benefaction. The circular centrifugal flotation cell has many originalities on the pulp aeration, air bubble mineralization, air pulp flow format in the ring shaped tank of the cell, feed method ect, due to the results of fluidics and turbulence and the action of centrifugal and gravitational force ect. By eliminating the recirculation and the froth paddle skimmers in the routine cell, the structure is simplified, the power is reduced, the maintenance is lightened, to realize easy operation, wider sized fraction, and easy automatic control. The laboratory exploration and the commercial tests show that expected separating index are controlled under the suitable condition, such as the combustible material recovery for the bituminous is about 90%, the capacity range from 2.8-3.0 t dry coal/h.m3. In additional, it is suitable application for any scale coal plant application through varying relevant parts.
