Recent developments on effective fine grinding . – pure.ltu.se. conventional comminution devices like tumbling ball mills. 2.1 Roller . total specific energy consumption of the comminution system is 20 to 50 % less . roller press and the effect of roller press grinding on the energy consumption of the …

I totally agree with you that the low charge rate directly affects the grinding efficiency, but in here there is another thing we have, that shouldn’t be overlooked, it is the power consumption, at low charge rates below 20% the power consumption increase by 6-15% for the ball mills.

Mill (grinding) Wikipedia. W is the work index measured in a laboratory ball mill A SAG mill with a 44′ (13.4m) diameter and a power of a 30 to 50% lower specific energy consumption, .

In determining the proper mill size required to meet a targeted production rate, many factors . degree with respect to specific power consumption (kWh/ton) and product . efficiency including ball size distribution, mill length to diameter ratio,.

· Specific power consumption- high for ball mill and Low for VRM Maintenance costs- high for VRM and low for Ball mill Process control/process technology- ball is operation friendlt and simple in operation but VRM requires some PID or control technology.

the specific power consumption of a ball mill is higher than that of a vertical roller mill (VRM) carrying out the same oper – ations by a factor of between 1.5 and 2, depending on the degree of optimisation of the ball mill. Fig. 1 illustrates this

In order to evaluate the effects of ball mill loading on specific power consumption and production it is necessary to discuss the actual design basis upon which the equipment sizes in a mill system are selected. a closed circuit system involving a ball mill and a high efficiency separator (HES) will be evaluated.DESIGNING THE RIGHT MILL SIZE .

Below 30 microns, the advantages of a horizontal stirred mill become dramatic and below a certain point, the horizontal stirred mill is the only choice as a ball mill cannot produce a 10 micron product at any practical power consumption.

High pressure roller press can be introduced as a pre-grinding step for the ball mill, in order to decrease specific power consumption in finish grinding and/or to increase the output of finish mill.
