[A method of separating solid particles according to size alone is called screening]
In the crushing section, the ore as it comes from the mine is broken down dry to a size suitable for the wet grinding machines ; these can, if necessary, be made to take lumps of 2 in. size, but they work much more efficiently if their feed is 189; in. or less.

Machine Coolant Cleaning Systems Carbide Processors
Machine Coolant Cleaning Systems Contaminated machine coolant are directly responsible for 70% to 90% of machine tool wear and failure. A filter system that removes contaminants as they are generated helps keep machine coolant operating at peak performance.
