Generally speaking, the suitable density is close to 80% when feeding size is large and circulating load is high. 4. Ball mill rotating speed: when grinding ball adding rate remains constant, the useful power of ball mill varies with the rotating speed, therefore, production efficiency will also be influenced. Ball mill rotating speed need to ...

The circuit was characterised by a high circulating load around the ball mill, with a bank of 20 inch (CAVEX 500) cyclones generating a coarse overflow P80 size of around 200µm to 220 µm which reported to the leach circuit.
Circulating Load Ratio - Scribd- Circulating Load Calculation In Ball Mill,Natasha Chandri Egieara Mineral Processing 1306436741 Circulating Load Ratio Circulating load ratio (CLR) is defined as the ratio of the amount of solids going through the ball mill divided by the amount of solids going through the circuitA New Macrophenomenological Concept of ComminutionA New Macrophenomenological ...
ore per day in six overflow ball mills. The concentrate is transported to a smelter a few miles away. The crushed ore from primary and secondary ores is conveyed into bins. The ore from the bins is fed into the ball mill using a conveyor belt. The ball mill grinding circuit is illustrated in Figure 2. % Solids 78.9 Circulating Load 474% Advance ...
The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding.

Definition of circulating load i. In mineral processing, use of a closed circuit to check mineral issuing from a specific treatment and to return to the head of the treatment those particles that do not satisfy the maintained conditions for release to the next stage of treatment.
benefits of circulating load. Figure 2. Effect of circulating load and classification efficiency on milling circuit capacity [10] 2. Mathematical model ¨ The grinding kinetics in the ball mill follows first order grinding law which states that the rate of production of fines (D) is
CONCLUSION The circulating load and classification efficiency can have a significant effect on the performance of both closed ball mill and HPGR circuits. This is a well-known fact for ball mill circuits that has been recognised for almost 100 years. For HPGR circuits the knowledge is more recent, and is still being investigated.

A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in .
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 .

Circulating load formula in ball mill klabrickellparents com015 08 10 calculation of circulating load with in ball mill circulating load calculation formulahere is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit calculating circulating load ball mill macimpianti.
In order to maintain the same flow gradient, the load inside the mill increases and the mill draws more power. In turn, this leads to a higher rock to ball ratio, resulting in insufficient grinding energy and a further increase in load inside the mill. Pebbles flow-back
flow, which is the fresh feed to the second ball mill. If circulating load in the second ball mill is kept constant, any variation in the fresh feed will ultimately be reflected in the product particle size of Cyclone 2. Water addition to Cyclone 1 feed sump therefore not only controls the Cyclone 1
Sep 07, 2011· Re: VRM and ball mill circulating load. Mainly in USA, the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines & it can be calculated by : Coarse return TPH X 100 / Mill output TPH.Normal range of cirulating load in a conventional close circuit ball mill is around 100-200%.
