2015-4-16mill at each stress event, the so-called stress energy The total number of stresses and the crushing time determine the product quality The stress energy of all stresses is not constant it corresponds to a distribution of the stress energy. The product related stress model contains the following aspects The effect of grinding media.
2020-8-18balls which exist in mill, each ball abrasion g, t total ball abrasion in the mill g, b each ball volume m3, b supposed ball filling percentage, A r ball abrasion rate in the mill. If above calculation were done again for b 2, total ball abrasion will get 60.96, finally.
2016-11-18Figure 2 shows the active grinding area for an optimally charged ball mill. As the drum rotates, the media should ideally form a sloping pile that maintains a 45 degree angle so that there is a constant cascading of media at the surface. Because the media is falling the fastest and for the longest distance at the top of the pile, the majority.
