Jul 31, 2014· Wm = Wi ( 80P 10 - 80F 10 ) (1) where: Wm - is mill specific motor output power (kWh/t), Wi - is the Bond ball mill work index (kWh/t), P80 - is sieve size passing 80% of the mill product (µm), F80 - is sieve size passing 80% of the mill feed (µm), The “efficiency factors” (Rowland, 1975) modify equation 1 so that it caters for circuit conditions which are different from that Bond used to develop his original …
Although it was developed nearly 50 years ago, Bond‘smethodis still useful for calculating necessarymillsizes andpowerconsumption for ball and rod mills. This paper discusses the basic development of the Bondmethod, the determination of the efficiency correction factors based onmilldimensions and feed characteristics, and the application of the results to designing grinding circuits.
Forcementplant with annual output of 1 million tons ofcement, this will create a profit of ～$1.47 million every year. According to thecalculationof clinkerpowerconsumption 45 kW·h/t, standard coal consumption 140 kg/t andcementgrindingpowerconsumption 40 kW·h/t, every ton ofcementproduction can be realized:

911Metallurgist sources manufacturers of all the provenmilldesigns in a “small” range of sizes — your assurance of getting the most suitablemillfor your purpose. Best grinding efficiency and economy can be obtained only when the type and size of yourmillis matched with your grinding job. Mills can also be furnished with modifications to suit any special application.
Apr 01, 2001· 2.1.2 Pan Mixers . All pan mixers work on basically the same principle []: a cylindrical pan (fixed or rotating) contains theconcreteto be mixed, while one or two sets of blades rotate inside the pan to mix the materials and a blade scrapes the wall of the pan.The shapes of the blades and the axes of rotation vary. Figure 4 shows the different combinations of blade configurations and pan.
