Application of the ultrahigh-capacity heavy medium cyclone at Huaibei Mining Company

In order to further extend the upper size limit of raw coal feed of the existing H.M. cyclone and tackle the problem regarding the heavy impact on hourly capacity of the cyclone exerted by the high content of dirt in raw coal, a super S-3GHMC870/410 H.M. cyclone is applied in the 1^# system of the plant's west section in replacement of the two 3GDMC1300/920A gravity-fed 3-product versions originally used. Industrial test shows that the super version can operate with a host of attractions, such as high separation sharpness, further reduced lower size limit of separation, high raw coal treating and deshaling capacities, and noticeably reduced power consumption, and its use can also lead to much simplification of existing washing system. The successful application of the cyclone well demonstrates its huge potential and broad prospect for widespread industrial application, and promotes its application later in the renovation of the plant's 2^# and 3^# systems, Guobei plant and Qinan plant.
