Abstract in determining the proper mill size required to meet a targeted production rate, many factors are evaluated including length to diameter ld ratio, individual compartment lengths, rotational velocity, liner type, ball gradation and percent filling degree. this paper examines the effects of changing mill filling degree with respect to specific power consumption kwhton and.
Re vrm vs ball mill for cement grinding. specific power consumption- high for ball mill and low for vrm maintenance costs- high for vrm and low for ball mill process controlprocess technology- ball is operation friendlt and simple in operation but vrm requires some pid.
The ball mill has been the industrys workhorse for over a century and despite its estimated meagre four per cent efficiency, little has changed over the years other than increases in the wear resistance of mill internals and the scale of the equipment. ... the main energy issue was the high power consumption of mill fans, with pressure drops.
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.
Specific power consumption of ball mills for . a cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement most cement is currently ground in ball mills and also vertical roller mills, energy consumption is typically half that of a ball mill, the main measure of fineness today is specific.
Charge behaviour and power consumption in ball . the specific power consumption for these two ball shapes is shown in fig. 16. for n75 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.
Wm wi p80 10 - f80 10 1 where wm - is mill specific motor output power kwht, wi - is the bond ball mill work index kwht, p80 - is sieve size passing 80 of the mill product m, f80 - is sieve size passing 80 of the mill feed m, the efficiency.
First, lets define what the specific energy consumption is. specific energy consumption is the power draw of a mill kw, usually corrected to the pinion or mill shell divided by the fresh feed.
Scale-up criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. for the full scale mill, specific power is multiplied by the feed rate to get the net mill.
Difference between vertical mill and ball mill. this is why we choose ball mill for clinker grinding. method of the vertical mill is reasonable, grinding power are fully utilized by materials, and grading is in time to avoid the phenomenon of overgrinding materials. so it has high grinding efficiency, low power consumption saving more than 20.
