High recirculating loads in Ball Mill Circuits Grinding ...

The ball mill has higher circulation load, it generates only 30 35% of actual fines you require to be called as product. If your product size needed is passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. The rest is oversize which has to be ground again.

PDF Intelligent optimal control system for ball mill grinding process

The ball mill grinding process is mainly composed of a ball mill, a hydrocyclone cluster, a sump, a slurry pump and an ore bin. The schematic diagram of this process is shown in Fig. 1. Fig. 1 Schematic diagram of ball mill grinding process. The variables of this process shown in Fig. 1 are explained as follows: W

Ball Mill Circulating Load 911 Metallurgist

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.

PDF Cement grinding Vertical roller mills versus ball mills

get a cement quality that is similar to the quality of cement ground in a ball mill. There are a number of ways to adjust the inclination of the particle size distribution curve for cement ground in an OK mill. In order to reduce the circulation factor, the grinding track on the grinding table has an upward curved shape that helps to retain a ...

NEW PRODUCTION RATE OF MILL BASED ON NEW BLAINE SIZE Formula 1

You can calculate the new production rate of ball mill based on the new blaine size, you just need to input following parameters: 1. Old Production rate. 2. Old Blaine. 3. New Blaine. you can also calculate the following mill calculationClick Below. 1.

Cement grinding Vertical roller mills VS ball mills

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied.
