the feed are wasted. As a result, the mill unit operating cost increases directly by the amount of the dilution factor. For example in a project whose processing cost has been estimated at 18/t,a 10% dilution means spent processing waste in the mill for every tonne of feed. For a 30,000 tonne a
Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravityfed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
