    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 ...How Hammer Mills are DesignedA hammer mill and a roller mill will enable you to achieve your desired result. However, you also have to consider other factors before you choose the method for grinding. You need to keep in mind that if you excessively reduce the size of the material, you will be wasting electrical energy which usually results in an unnecessary wear on the equipment used.DEVELOPMENT AND TESTING OF A HAMMER MILLThe hammer mill was designed and constructed from locally available materials for grinding grain particles such as maize, millet, guinea corn and other coarse materials of cassava tuber, yam tuber, beans, etc. into small size enough to pass throughFeed Mill Efficiency - EngormixRoller mills are more energy efficient than hammer mills when grinding friable materials; the advantage for corn is <5% at sizes smaller than 500 microns, becomes 25-30% at 800 microns, and increases to perhaps >80% at a size of 3000 microns (CPM, 1992). The hammer mill (Figure 4) remains the industry standard for size reduction.Top 5 product-specific milling technologies used in .By controlling the mill weight, the optimal amount of material is always in the mill bed and the milling efficiency is optimized by never under- or over-filling the mill. The classifying air volume is measured and kept constant by the use of a thermal mass flowmeter and control device, to .
