Grinding control strategy on the conventional 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,

Ball Mill Operation -Grinding Circuit Startup & Shutdown

Feb 01, 2016 Ball Mill and Grinding Circuit Emergency Shutdown. In the event of an emergency, the mill feed conveyor is shut down individually or by stopping the operating cyclone feed pump. The ball mill must be shut down separately. All equipment shutdowns are performed locally or from the MCC located in the mill control room.

Ball Mill Cyclone overflow P80. Grinding

I would like to know the effect of ball mill cyclone overflow density on P80 of 150um. I ask this because at either higher or lower densities, you can get your P80 @ 150um (at least 80% passing 150um). Kindly advise on what densities would you get the P80 best for floating c

Ball Mill Circulating Load Mineral Processing & Metallurgy

Oct 09, 2015 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. That is, for every incremental increase in circulating load of

Grinding Circuit an overview ScienceDirect Topics

The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed

DENSITY IN THE GRINDING CIRCUIT WHITEPAPER

produced by the ball mill, so the cyclone overflow allows a lot of these middle size particles to escape the grinding circuit. This results in a decrease of material that the ball mill would have to grind, which lowers its efficiency. Also, unwanted particle sizes are leaving the grinding circuit to next process stages.

Then the circulating load ratio is equal to 'A' divided by 'B', the number of passes through the mill needed to generate the total amount of new circuit product. Example: A ball mill circuit product (cyclone overflow) contains 80% passing 75 um (200 mesh). The circuit feed (from the previous stage of size reduction) contains 20% passing 75 um.

cyclone performance on ball grinding mill

Ball Mill Grinding Circuit The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators.
