Each screening unit has an effective screening area of 4.27 m by 8.53 m (14’ width x 28’ length). The screen oversize from each HPGR line is conveyed back to the HPGR units for further size reduction. The screen undersize, with a P80 of approximately 2.0 mm, is conveyed to two parallel Ball Mill grinding lines

ball milling | material milling, jet milling | aveka

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e
