An innovative approach for determining the grinding media system of ...

An novel approach for determining grinding media system of ball mill was proposed. • The optimum media ball size of three size fraction samples were obtained. • The media size ratio was ascertained as φ 50 mm: φ 40 mm: φ 30 mm = 28%: 28%: 44%. • The installed power and productivity of ball mill (Φ5.03 m × 6.40 m) were calculated.

Coal Mill in Cement Plant | Vertical Roller Mill & Air-Swept Ball Mill

The ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%. Therefore, the ball mill should have a drying function besides grinding.
