Design of the kubaka grindng circuit using spi and . the kinross kubaka project is a gold mine located in the russian far east. the grinding circuit comprised of a 6.1 m diameter x 2.74 m long sag mill and a 4.1 m diameter x 5.5 m long secondary ball mill in closed circuit with cyclones was built using sag power index and bond ball mill work index testing to determine the grinding energy.

The only manipulated variable available in the closed milling circuit (ball mill 2) is the cyclone dilution water flow rate. Attempts to use this for density control were not successful. Because of the high magnetite concentration of the ore it was found that the actual density exceeded the required density, causing the density control loop to become unstable. If the operator did not intervene

18.07.2016· Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines. The coarse fraction is sent back to the mill

Closed Circuit Grinding VS Open Circuit Grinding. From a theoretical point of view, the ideal method of grinding would consist of a series of ball mills, each in closed circuit with a classifier and each so short that the ore in its passage through the mill would be struck only two or three times by the balls, any undersize produced being removed at once by the classifier ; in this way the

Closed circuit ball mill Basics revisited ScienceDirect. 1. 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

Based on experience acquired over the years and the investigative work conducted by F.C. Bond, it was established that the optimum circulating load for a closed ball mill – cyclone circuit is around 250%. This value is used as guideline for the design of new circuits as well as to assess the performance of existing circuits.

In a closed mill circuit the oversize particles are returned from the post milling processes to be remilled whereas with an open circuit the process has no feedback loop. In dry grinding systems, the material from conventional crushing and screening operations is subject to coarse and fine grinding primarily in roller mills or ball mills to reduce the material to the necessary product size
