**Function:** Dense Medium Cyclones (DMCs) are critical in mineral processing for separating particles based on their density. The cyclone creates a centrifugal force by feeding the slurry into the cyclone tangentially, causing the dense particles to move toward the wall and the lighter ones to stay closer to the center.

When the cyclone returns ore to the ball mill, both the total volume of ore and the slurry density increase in the grinding circuit. This recycled ore is referred to as the circulating load. If the grinding process becomes less efficient, the circulating load will continue to rise until it exceeds the circuit's handling capacity.

One of the more robust heuristics in mineral processing is that liberation by size remains approximately unchanged across a comminution circuit. As discussed in the introduction, such a heuristic has been tested widely in the mineral processing research, but except for the work of Mainza et al. (2004), the classification principle was not ...

Most mineral and coal processing plants are forced to size their particulate streams in order to maximize the efficiency of their unit operations. Classifiers are generally considered to be more practical than screens for fine sizing, but the separation efficiency decreases dramatically for particles smaller than approximately 150 µm.

Mill ball load can be reduced from 35 per cent to 30 per cent according to simulation results. This modification reduces specific energy consumption of the ball mill by approximately 10%. The TBS can be used as an alternative and more efficient classifier to further improve the classification efficiency of close circuit grinding operations.

Cyclones are generally used in most mineral processing plants to classify the ground product of the mills in preparation for downstream processes such as flotation and leaching. Cyclones are generally considered to be more cost effective to classify particles due to their lower footprint, higher utilisation and lower capital and

For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load ratios and circulating load tonnage on tons/day or tons/hour.

Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).

Alloy Cyclone Size and number of units The size and number of cyclones required for your application depends on the material you are treating and your process objectives. In many applications, a single cyclone will provide the capacity you need. In general, a larger cyclone has higher capacity and a smaller cyclone recovers a finer particle size.
