Ball Mill (Ball Mills Explained)

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.

Semco Carbon Graphite Machining

First, synthetic graphite should be machined dry without the use of liquid coolants. The use of coolants when working with graphite will produce an abrasive slurry when the coolant combines with the fine bits of graphite chips and dust. The coolant fluid will also permeate the graphite material through the open porosity of the material.
