离心式脱水机在三个选煤厂使用两年后,实践证明,其性能比其它许多脱水装置好(包括圆盘式过滤机)。粒度在-0.5毫米(32网目)的极细颗粒的部分,在鲁尔煤矿公司的RAG选煤厂五年间已从平均的15％增加到20％,因而需要脱水的精煤或煤泥量也就相应增加,为降低出售煤的 After two years of operation at three coal preparation plants, centrifugal de-watering machines proved to be better than many other dewatering units (including disc filters). The fraction of very fine particles with a particle size of -0.5 mm (32 meshes) has increased from an average of 15% to 20% over the five years at Rue Coal’s RAG coal preparation plant and thus requires the removal of clean coal or slime It will be a corresponding increase in order to reduce the sale of coal
