ATOX coal mill
the standard solution for coal grinding installations And thanks to our continuous refinement of the ATOX coal mill over the years, today’s leading airswept vertical roller mill is the compact ATOX Offering high reliability, low installation costs and a wide range of sizes, the ATOX grinds and dries all types of coalDrying 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 burningCoal Grinding Cement Plant Optimization
