The pulverized coal needed for coal injection is produced in coal grinding and drying plants. At present these plants range in capacity from 15 to 240 tons/hr. As an example, the coal grinding plant with Loesche roller grinding mills in operation at the ILVA steelworks in Taranto, Italy will be described in detail.

Abstract Ball drum mills (BDM) are one of the main types of coalgrinding equipment in Russia. A significant drawback of BDM is high power consumption (a significant part of the TPP's own needs). With a huge scale of production, reducing these costs even by a few percent gives a significant economic effect. The problem of minimizing the specific energy consumption for grinding and ...

An estimated consumption of steel grinding media of around 600,000 tons in the 1980s already gives an indication of the scale of the problem (Malghan, 1982). Likewise, in the cement industry, as mills are supplied for ever increasing capacities, the ball size distribution and wear exact a tremendous effect on the profitability of producing ...

Ballmills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (725 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.

In SAG mill operation, the grinding rate passes through a minimum at a "critical size" ( Chapter 5 ), which represents material too large to be broken by the steel grinding media, but has a low selfbreakage rate. If the critical size material, typically 2550 mm, is accumulated the mill energy efficiency will deteriorate, and the mill ...
