Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated with a.

Presses and vertical roller mills, and describe the benefits and comparisons of each system. difference in grindability of the two materials. fineness of PFA usually varies between 200 and 500 m2 kg (Blaine), (or 45 m residues A ball mill offers a very well proven and sturdy technology for grinding of blended cements.
Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between.
The application of ball mill power from fine (minus P80 product size) to coarse material, circuit efficiency is increased and overgrinding is hardness, and other factors. Consumption is closely related to total ball charge surface area. • A useful guideline for make-up ball size for a.
2. Reducing the power consumption of the raw material preparation effectively. According to the display of material production measured data, it can be saving electricity above 30 use of vertical roller mill production per ton raw material than traditional ball mill, and power saving effect is very remarkable. 3. Finished product has high quality.
These features distinguish stirred mills as fundamentally different from both ball mills and Tower Mills, as demonstrated by Tables 1 and 2. Table 1 Typical Power Intensities of different Grinding Devices Table 1 Power Intensity of Different Grinding Devices Ball Mill is a 5.6m D x 6.4m L @ 2.6MW Tower Mill is a 2.5m D x 2.5m L @ 520KW.
May 11, 2020 In March 2018 the ceramic balls were installed in mill No 2. According to plant data, resulting power consumption has fallen from 30.04kW h to 26.88kW h – a reduction of 3.16kW h.
