摘　　要：为进一步提高煤泥浮选效果,降低浮选药剂用量,马头洗选厂采用重力流态式矿浆预处理器对浮选系统的矿浆预处理设备实施了技术升级改造。文章介绍了重力流态式矿浆预处理器的结构、工作原理、技术特点及其在马头洗选厂的应用效果。实践表明:该矿浆预处理器投入使用后,在浮选处理能力提高12.18%、浮选完善指标提高3.18个百分点的情况下,捕收剂和起泡剂耗量分别降低31.78%和11.41%,浮选精煤灰分合格率从70%提高到90%。Technical upgrading work is made on the pulp preprocessing unit of the plant~ flotation system through the use of gravity-flow preprocessor for further improvement of flotation performance and reduction of consumption of agents. The paper presents an introduction to the structure, working principle, technical features of the gravity-flow pulp preprocessor, and the effect of its field application at the plant. Practice shows that the application of the pulp preprocessor has achieved the remarkable effect as follows： in addi- tion to an increase of the capacity of the flotation system by 12. 18% and a rise of the flotation perfection index by 3. 18 percentage points, the consumptions of collector and frother are reduced respectively by 31.78% and 11.41% , and the qualification rate of ash of concentrate is increased from 70% to 90%.
