Screening 101 - Mineral Processing & Metallurgy

If, for instance, it is observed that 40 percent of the sample had passed through the 8-mesh testing screen and was retained on 10- mesh and another 40 percent had passed through 10-mesh and was retained on 14-mesh, an efficient production screening operation at 10-mesh would require the maximum in screen area, particularly as to length.

South Africa and coal - SourceWatch

In the case of South African coal, recent studies are suggesting production has already reached its peak, or soon will. Coal provides 70% of the country's energy supply, supports 90% of electricity generation, is used to make a quarter of the country's liquid synfuels using the process, and is a big earner of foreign exchange through exports to foreign users.

SCREEN CAPACITY CALCULATION - VIBFEM Home

A commonly used rule of thumb in determining the amount of water required calls for 5 to 10 gallons/minute per yard/hour. For 100 lb per cubic foot material 5 to 10 gallons/ minute per yard/hour equates to 3.7 to 7.4 gallons/minute per ton/hour. Insufficient water volume may turn fines to sticky mud causing blinding.
