The effect of the ball size distribution on the milling rate of coal has been measured as a function of ball size distribution. The change in ball size distribution as affected by wear and ball top-up policy has been modelled. From this a best ball top-up policy can be recommended that will ensure a close approximation to the desired steady-state ball size distribution that gives the required PF size distribution for the …
The raw coal and lump coal are coarsely crushed by the crusher and crushed to 3mm to meet the feed size of the CWS ball mill. The cleaned coal obtained by flotation is mixed and stirred in a mixing tank by adding a certain proportion of water.
May 01, 2014 It is however clear that within the range explored the 30 mm ball is preferable to the standard 50 mm in current use. The two are compared further in the next section. The fact that they never use 30 mm balls probably indicates that all coals have a …
Ball Mills. Ball mills have been used for the preparation of coal–oil and conventional coal–water slurry fuels, also in large sizes up to a capacity of 50 tonnes of coal per hour (Austin et al., 1984).

These balls reduce in size as the mills operate and so the highest size ball is normally used for recharging. In earlier days, most of the ball mills had a single inlet and outlet, but now designers use both ends to feed coal and also for taking out pulverized coal.
Grinding balls such as Allmax grinding balls are extremely robust and have a long working life. With a grinding ball sorting machine from Christian Pfeiffer, their use becomes even more efficient. This is because the grinding balls can be precisely checked after passing through the sorting machine.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum’s volume so that the total volume of the drum is 50% charged.
