我厂在开滦煤炭科学研究所的协助下,自1975年10月应用X—1型压滤机回收细粒高灰煤泥以来,实现了煤泥厂内回收和洗水闭路循环。到1977年10月底共进行了2469个压滤循环,回收煤泥14265吨。压滤效果一直良好,从而保证了重介选煤车间的正常用水。有关我厂煤泥水的工艺流程、压滤机的结构、处理量的计算方法等,《选煤技术》一九七六年第三期中已较系统刊载,这里仅对两年多来我厂使用压滤机的情况 With the assistance of Kailuan Institute of Coal Science, our factory has realized the closed-circuit recycling in slime plant and water washing since the application of X-1 type filter press to recover fine-grained high-ash slime since October 1975. By the end of October 1977, a total of 2469 pressure filtration cycles were carried out to recover 14,265 tons of slime. The pressure filtration effect has been good, thus ensuring the normal use of heavy medium coal preparation plant. About our plant slime water process, filter press structure, processing capacity calculation method, “coal preparation technology” in 1976 the third period has been more systematically published here only for more than two years I plant use Filter press situation
