| Abstract: | Tests of coal slime dewatering were carried out with a laboratory filtering centrifugal device. The functions of cake filtering in the centrifuge and the factors determining the recovering of ultra-fine powders were studied. The mechanism and effect of centrifugal filtering, dynamic cake, and centrifugal factor gradient were also analyzed. The results show that these factors are significant for improving the centrifugal dewatering of coal slime. |
