Ultra Fine Coal Cleaning - 911metallurgist

The float coal products were washed with acetone and dried in an oven at about 105°C for five hours to remove the residual liquid. The clean coal was dry-ground to very fine sizes in a stainless steel attritor. The cumulative weight of the size below 25 microns was 50% for the Upper Freeport coal and 75% for the Pittsburgh No. 8 coal.

Build an Ultra-fine Grinding Mill - 911metallurgist

Silica sand is a viable alternative for steel shot in fine grinding of coal. In addition to the low costs of silica sand, there are also the benefits of low specific energy consumption and wear associated with the use of silica sand. However, the unit capacity of a mill may be reduced slightly when silica sand is used as a substitute for steel ...

Dewatering of Ultrafine Coal by Filtration

Dewatering of a -0.5 mm fine coal has been studied extensively. Deep cleaning requires however fine grinding, and dewatering of such ultrafine products presents a great challenge. Several coal samples finely ground and characterized by different wettabilities have been used in the filtration tests. Vacuum and press filters have been employed.
