Efficiency of stirred ball mills Conference OSTI.GOV

Dec 31, 1995 Stirred mills were first introduced in the 1950`s as an alternative to ball mills in a regrind application. Since then they have been used to grind a range of materials from limestone to coal to sulfide concentrates. A laboratory tower mill was used to investigate the effect of some variables on the power requirements of a plant mill.

Coal Grinding Cement Plant Optimization

Coal Grinding Cement Plant Optimization

Drying and grinding are generally being done in either air swept ball mill or a vertical mill. The selection of mill system will depend mostly on the factors like initial capital cost, drying and grinding capacity required, cost of energy (power) etc. Coal Fineness: It is understood generally that the finer we grind, the easy it is for burning. However, the fineness required will always be directed by where to fire and what type of coal …

May 01, 2012 Two samples of coal (Indonesian and Chinese) were used to optimize the grinding conditions of the hammer mill. The results of the proximate analysis and the Hardgrove Grindability Index (HGI) of coal samples are provided in Table 1. Not only was the moisture content of all samples below 25%, but the energy content values were all below 25.0 MJ/kg. The samples were lighter in color than subbituminous and bituminous coal.
