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
A feature of ball mills is their high specific energy consumption. A mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, that is, during the grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages
between the ball-mill power draw values determined from the Denver slide rule, and those calculated from the proposed model. zFrom the distribution of the points around the line of comparison the good agreement of the results received is obvious. 0 200 400 600 Ball mill power draw predicted from the Denver slide rule, kW 0 200 400 600

Power Consumption Of Ball Mills For Limestone. Ball mill specific power consumption. ball mill power calculation example 1. a wet grinding ball mill in closed circuit is to be fed 100 tph of a material with a work index of 15 and a size distribution of80 passing 188 inch6350 microns. the required product size-
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 power.
Power scale up is accurate because power is measured as power consumption at the agitator shaft to determine the specific energy requirements and size the mill and PSD scale-up is accurate because of the horizontal IsaMill layout, which eliminates any short circuiting, and the classifying action of the product separator.
production is obtained from a ball mill when the mill motor power is at a maximum and consequently the specific energy consumption is at minimum. The maximum power point is dependent upon the feed material characteristics, mill liner conditions, grinding media charge and product size requirements. 4.2 Working principle
a conventional ball mill circuit. The result an increase in production of approximately 25 percent, and a reduction in specific power consumption of about 10 percent compared to a conventional ball mill system. Semi-finish grinding Upgrading a ball mill system with an HRP in a semi-finish mode is a simple solution, and installation is easy.
A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball millthird-generation separator, CKPball millthird-generation separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption.
Roll presses are also used in, particularly in upgrading existing ball mill circuits as pre-grinders to increase production or to reduce specific power consumption in grinding operation. Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas 2.5-3.5Msec above the ball charge, can ...
