Power consumption for ball mill for gold

Power consumption for ball mill for gold

Feb 13, 2017 In a pebble mill the pebble consumption ranges from 3—15 % and the charge has to be controlled automatically to maintain uniform power consumption. The volumetric density of a rod and a ball charge is around 4.9 ton/m (310 lb/cu.ft) corresponding to 37 % void space

    May 08, 2017 1 – 1.01/1 – 0.4 = 1.5. Thus, the power to drive a rod mill, without a powder charge, will be given approximately by. PR = 1.5PB …………….. (3.24) where PR is the power to drive the rod mill and PB is the power to drive the corresponding ball mill, as calculated from the foregoing formulae

  • The effect of processing parameters on energy The effect of processing parameters on energy

    grinding media (steel balls) on power requirements and energy consumption of a ball mill. With constant mass of the steel balls (20, 30 and 40 kg), the agitator shaft speed was increased from 10 to 100% of the maximum speed, which corresponds to a speed of 50 rpm. The power consumption (W) was recorded upon which milling energy consumption

  • power consumption for ball mill power consumption for ball mill

    High pressure roller press as pregrinding to ball mill Specific power consumption decreases by about 10 Reductions in specific energy consumption in the range of 724 kWhtcement 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

  • Charge behaviour and power consumption in ball mills Charge behaviour and power consumption in ball mills

    Aug 01, 2001 The specific power consumption for these two ball shapes is shown in Fig. 16. For N≤75% there is no change in the mill power draw. This occurs because the center of mass of the charge is little changed by the particle shape at these speeds. At intermediate speeds, the power draw for the non-circular balls falls off rapidly

    Consumption Typical power requirement of finished ball mill Example: Total consumption 3333 kW, 104 t/h product = Total Power Consumption = 32,0 kWh/t Mill Power Consumption = 27,5 kWh/t (85,8 %) Energy consideration in cement grinding

  • Optimization of mill performance by using Optimization of mill performance by using

    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

  • CALCULATION OF THE POWER DRAW OF DRY CALCULATION OF THE POWER DRAW OF DRY

    Key words: power draw, cement, dry grinding, ball mill INTRODUCTION Energy is the most important cost item in a cement plant. About 60% of the electricity consumption for cement production is used for grinding the raw material and cement clinker (Zhang et. al., 1988). Annual cement production is

  • Fine Grinding as Enabling Technology – The IsaMill Fine Grinding as Enabling Technology – The IsaMill

    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

  • Spiral Classifier - Mineral Processing Spiral Classifier - Mineral Processing

    Compared with hydrocyclone, the power consumption is lower. 7. The main disadvantage is that the classification efficiency is low, the equipment is bulky, and the floor space is large. Due to the limitations of equipment specifications and production capacity, it cannot generally form a closed circuit with a ball mill of ф3.6m or more
