ABSTRACT

The handling and storage of materials constitutes a major function in all Mineral Beneficiation plants. Angle of repose is defined as the included angle formed between the edge of a cone shaped pile formed by dropping the material from a given elevation and the horizontal. Tackiness is the tendency of a material to stick to surfaces on which it is deposited and to cling to adjacent particles. A rough test for tackiness is to try to form a ball of the material by rolling it between the palms of the hands. The materials like coke and foundry sand will wear hoppers, chutes, screw feeders and conveyors, and pneumatic handling systems. When corrosive materials are processed, they must be handled in equipment with contact surfaces of alloy steel, special plastics or coated with corrosion resistant paint. Materials that have an inherently high percentage of moisture may pose a handling problem.
