Ball Mill for Gold Mine in Zimbabwe

Gold Grinding Operation

Gold grinding is a unit process used in a broad range of industrial application to produce fine particles. In recent years,the product size specifications for advanced materials have become extremely fine, some times approaching the nanosize range. However, it is very difficult to produce particles in this size range by grinding and, moreover, ultrafine is expensive due to low mill capacity and high energy consumption.

In this plant, grinding circuit consists of pregrinding with an open rod mill and finish grinding with a ball mill in closed circuit with hydrocyclones and followed by a thickeiner. The ore is very abbrasive and hard to grind. Also grain size is 1-3 micron. This fine grain of gold size sometimes causes descent of gold recovery.

Ball Mill for Gold Mine

Ball mills are constructed with replaceable liners composed of high-strength chromemolybdenum steel bolted onto the mill shell. The grinding face of the liner is ribbed to promote mixing. The liners require extensive maintenance and must be replaced regularly.

The ball mill works by tumbling the ore against free steel balls and the lining of the mill. It is a versatile grinding mill and has a wide range of applications. The mill can vary in size from small batch mills up to mills with outputs of hundreds of tonnes per hour. They are the most widely used of all mills. Small hand operated ball mills are used for preparation of ore, sand and gravel.

Wet Ball Mill Supplier

The wet ball mall is the key piece of equipment for grinding the ore after the crushing process completes. To use a wet ball mill appropriately, it is important to match the viscosity of the batch to the material being ground. Low-viscosity batches excessively wear the wet ball mill, while high viscosity batches prevent the material from being ground correctly.
