Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12). Parallel mill circuits increase circuit flexibility, since individual units can be shut down or the feed rate can be changed, with a manageable
Dec 26, 2015 In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock ( geometallurgy ) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
In all the ore mining beneficiation and concentrating processes, including gravity separation, chemical, froth flotation, the working principle is to prepare fine size ores by crushing and grinding often with rock crushers, rod mill, and ball mils for the subsequent treatment.

For crushing no grinding media is required, the ore size is reduced by external forces applied by the crusher. Dry crushing but wet grinding. Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling.
relative to their length, typically in the ratio or 2 or 2.5 to 1. AG mills employ ore as the grinding media. However, one the challenges with AG mills is that properties, such as hardness and abrasiveness, of the ore can vary, resulting in inconsistent grinding behaviour. The addition of steel grinding balls rectifies this situation.
Rod Mills (Heavy Duty Grinding) these rotating mills use rods for media causing friction and attrition between steel rods and ore particles. Rod mills can accept feed up to approximately 50 mm. (2 in.) and produces the product in the range of 3000 to 270 mm. More. suitable for breaking up large pieces of ore due to the heavy weight of the rods.
