Ore washining and water treatment
In mineralprocessing , Washing , mainly used in the enrichment process of industrial minerals, coal,aggregates, sand and gravel, normally with the products in solid form. (size = 1 mm and coarser). Log washers Single or double shaft log washers are used for washing of gravel. Contaminated material is fed at the trough bottom and is transported upwards by blades in abscrew pattern due to friction between the material. Effluent in slurry form leaves via an overflow weir. Wet screens Water spraying can be used to wash materials on a screen regardless of hole size in the screening media. If the hole size is 20 mm or less, water spraying increases the capacity (inversely proportional to the hole size). Aquamator separator The Aquamator is developed for efficient washing of waste material of lower densities like coal, wood etc. Used mainly for gravel, chippings and demolition rubble. The water and feed form a bed with a density high enough ( SG range1.2-1.6) enabling l...
