Recycled Crushed Glass In Concrete - Crushing Glass Uses

Modern gold operations with grinding circuits include a SBM mill and Ball mills whose operation is critical for the gold recovery process. The control of the ore reclamation system from stockpile and grinding circuit at the gold mining equipment are key aspects for the efficient performance of the operation. The purpose of the reclamation from stockpile and grinding circuit is to reclaim crushed ore from the stockpile and grind the ore to a size small enough to liberate the free gold and gold-bearing minerals in the crushed ore.

The term SBM mill is an acronym for semiautogenous grinding mill. The term autogenous grinding mill means that all of the grinding action is performed by the ore particles tumbling into one another. The size reduction is accomplished by the action of ore crushing and grinding other ore particles. In fully autogenous mills, there are no grinding media. In semiautogenous mills, a portion of the grinding is autogenous and a portion is performed by grinding media.

The recycled crushed glass is reclaimed from one or two stockpiles and the number of stockpiles is based on plant size and complexity of ore body. Basically a stockpile is equipped with apron feeders that discharge onto a SBM mill feed conveyor. A dust suppression system is used in the reclaim system and the dust is suppressed at each transfer point of crushing glass uses from the apron feeder onto the feed conveyor. The crushed ore is fed into the SBM mill for grinding by the SBM mill mobile belt conveyor. On its way the reclaimed glass passes over a belt scale installed on the SBM mill feed conveyor. The scale is important not only for plant metallurgical accounting but also because it is used in controlling the vibrating feed rate to the SBM mill.

Hydrocyclone are fed with SBM mill discharge, ball mill discharge, and water used for density control from the hydrocyclone feed pump. The overflow from the hydrocyclone goes to the leaching process (e.g. Carbon-in-Pulp, Carbon-in-Leach) or flotation circuit. The underflow from the hydrocyclone goes to the ball mill feed box. The ball mill for sale works in closed circuit with the hydrocyclone to grind the underflow.
