mineral processing technology and mineral processing equipment

In mineralprocessing plant , Dewatering by using Tube Presses represents the highest energy level of mechanical upgrading of minerals. If further upgrading is required we have to use thermal processing. Thermal processing is normally classified according to operating temperature. Thermal low ( 100-200° C) Used for drying - evaporating of liquids from solids - drying Type of equipment • Direct Heat Rotary Dryers • Indirect Heat Rotary Dryers • Steam Tube Dryers • Indirect Heat Screw Dryers (Holo-Flite R ) • Fluid Bed Dryers Thermal medium (850 -950°C) Used for calcining, clay swelling, limestone burning and foundry sand burn out Type of equipment • Direct Heat Rotary kilns • Indirect Heat Rotary kilns • Vertical Kilns • Fluid bed Kilns Thermal high (1300-1400°C) Used for pelletizing of iron ore concentrates and petroleum coke calcining Type of equipment • Direct heat rotary kiln Thermal processing basics Thermal processing is expensi...
