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 It is characteristics of the material and does not change with milling conditions (type of lifter, rotational rate, ball load, ball size or mill hold-up) (Austin and Brame, 1983). The value for the parameter Λ was chosen from the literature to initiate the estimation procedure (Austin et al., 1982).A comparison of the Bond method for sizing wet tumbling ball mills

Operability: dry limestone mills have a variety of dry-type mills to choose from, whereas wet limestone mills only have limestone ball mills to choose from. Environment: people often build the dry limestone mill outside the power plant as it needs multiple machines and a large site. No noise pollution and dust pollution in the power plant.Objectives. At the end of this lesson students should be able to: Explain the grinding process. Distinguish between crushing and grinding.

In this paper, fine grinding is used to describe the size reduction to an 80% passing size between 45 and 25 μm and ultra-fine grinding is considered for sizes below 25 μm. Fine grinding in traditional ball mills has not been utilised in the past due to the following perceived disadvantages: •.The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that What Are the Differences between Dry and Wet
