Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today's global markets, expanding mining groups are trying

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%.
"The circulating load ratio is necessary to determine the capacity of the ball mill initially. Once the ball mill is installed, you cannot change its capacity" The underflow is circulated into the ball mill as shown in the figure "The underflow is not a waste; it is further sent to the ball mill operation for further recovery of the ...
ball mill circulating load calculation circulating load Circulating load calculation in grinding circuits The circulating load can be defined as a process flow mass or volumetric of a given material. Get Price; What Is Vertical Roller Mill.
Additionally, lingering confusion about basics such as the relationship between circulating load ratio and ball mill circuit performance makes the optimisation objective seem nebulous to both plant metallurgist and designer.Some of this confusion can be eliminated by taking a step back from the overwhelming detail of sharpness of separation ...
Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed …
Highlights Circulating load and classification efficiency effect on ball mill capacity revisited. Relative capacity model introduced and validated. Relationship between circulating load and classification efficiency verified by industrial data. Existing fine screening technology could increase ball mill circuit capacity 15–25%.
Circulating Load In Ball Mill Video. 1 copper mountain overview on the grinding mills mill and two 24 x 395 ball mills will be briefly discussed all three mills the accuracy of the load sharing between the two motors normal operation after starting lower torque limitation eg 110 of rated torque on switch off the ball mills and therefore most likely will end up sometimes with either recirculating.
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 order to move closer to the exact solution.

Some of this confusion can be eliminated by taking a step back from the overwhelming detail of sharpness of. separation curves, circulating load ratios, cyclone feed pressures, vortex and apex sizes ...
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.
Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably …
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 …
Circulating Load Calculation Formula. Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill

Further simulations based on flowsheet modification options showed that a second ball mill (series configuration) can help to achieve the desired product fineness as well as an increase of throughput from 618 t/h to 780 t/h. Although the circulating load increases to approximately 500 % in this configuration, it is outweighed by the benefits.
