The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns. The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns. The Center-Periphery Discharge mill has feed reporting from both ends and the product.

Precautions Of Ball Mill Usage Fote Machinery(ftm)

The CL-5 Stirred Vertical Ball Mill for Limestone Grinding is a smaller version of the production sized CL Series Mills. It is ideal for research, scale-up and small-scale production. This mill will process in the range of 200-500 pounds of limestone per hour and is equipped with a variable frequency drive (VFD) and a 15 horsepower inverter.A feature of ball mills is their high specific energy consumption. A mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, that is, during the grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity.

And specific power consumption on the main drive (see Figure 1). Specific power consumption can be also reduced by using wet slag in an intergrinding process. A material containing 40 per cent slag with a moisture content of 3.2 per cent shows power consumption during intergrinding comparable to power use during separate grinding (see Figure 2).Specific power consumption decreases by about 10 . Reductions in specific energy consumption in the range of 7-24 kWh t-cement are reported (LBNL, 2008) Power consumption per ton of cement can be reduced by 8 ~ 12 kWh, representing 15 to 30 saving over a traditional ball mill system. System output can be increased by than 100 .

Ball Mill Design Power Calculation

Planetary Ball Mills are used wherever the highest degree of fineness is required.In addition to well-proven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying.The extremely high centrifugal forces of a planetary ball mill result in very high pulverization.Three types of tests are available for mill power determinations. In most cases one of two bench scale tests is adequate. First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr t) to grind from the design feed size to the required product size.
