Dec 12, 2016 · If P is less than 80% passing 70 microns, power consumption will be. Ball Mill Power Calculation Example. A wet grinding ball mill in closed circuit is .
The grindingproduct size, P, in a Bond ball mill, which is given by the aperture size which passes 80% of the grinding product as a function of the aperture size of the test screen Pk, can be expressed by the formula P= P k K 2. These functions for G and P enable us to calculate the value of Wi for any other size of grinding product if we know ...

MODELING THE SPECIFIC GRINDING ENERGY AND BALLMILL . 2 MODELLING THE SPECIFIC GRINDING ENERGY AND BALLMILL SCALEUP Ballmill scale up (Bond's Law)Data: zBond work index w i zFeed D f and product d size (both 80% cumulative passing) Result: The specific grinding energy w Mill power draw P = wT, where T the mill capacity Mill dimensions (from .
z c Number of inserts in the cut: a e /d 1 Ratio of radial width of cut to cutting diameter: Calculated Required Power. F t Tangential cutting force: lb N. T Torque at the cutter: Nm in.lb ftlb Nmm. Machining Power. P s at the cutter: (HPc) KW. P m at the motor: hp KW. These calculations are based upon theoretical values and are only intended ...
Jun 19, 2015 · The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
Specific Cutting Force ... What is the cutting power required for milling tool steel at cutting speed 80m/min. With depth of cut 2mm, cutting width 80mm, and table feed 280mm/min by ø250 cutter with 12 insert. Machine coefficient 80%. ... First, calculate spindle speed in order to obtain feed per tooth.
Energy consumption calculator. kWh calculator. Energy consumption calculation. The energy E in kilowatthours (kWh) per day is equal to the power P in watts (W) times number of usage hours per day t divided by 1000 watts per kilowatt:
Milling Speed and Feed Calculator. Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter ...
The Milling Process – Definitions Cutting speed,v c Indies the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indies the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters ...
