摘　　要：简述了GPJ-120型加压过滤机的结构、工作原理及技术特点;为了解加压过滤机的脱水性能、降灰幅度和分级作用,对潘集选煤厂的GPJ-120型加压过滤机进行了工业性试验;结果表明,加压过滤机脱水率为93.86%,脱水性能良好;滤饼绝对降灰平均值为0.79个百分点;次生细泥绝对增量为2.21个百分点,该设备对煤粒的分级作用甚微。The structure,working principle and technical characteristics of GPJ-120 pressure filter are briefly described;industrial test of GPJ-120 pressure filter at Panji coal preparation plant has been carried out in order to understand the dewatering performance,ash reduction and classification of pressure filters;the result shows that the dehydration rate of the pressure filter is 93.86%,and the dehydration performance is good;the average absolute ash reduction of the filter cake was 0.79%;the absolute increase of secondary fine mud is 2.21%,which has little classification function for coal particles.
