人们已经精确地讨论了现行的按比例放大公式,并且改进和推广了最近导入公式的一个概念,即介质旋转质量流和矿石轴向质量流的比率。对比矿石与介质的碰撞次数和具有比能常数的平均冲击能。可以说明按比例放大的磨机的相似破碎。进一步的结果是,在单元矿石停留于磨机的期间,磨机的平均转数和矿流路经的弯曲度都将显著地减少,而轴向流却随磨机直径的增加而非常剧烈地增加。当磨机直径达到临界范围时,特别对某些给矿较粗的矿石这些因素可导致磨机生产能力受限制。由于自磨机的大部分有效体积完全地或大部分地由矿石所占据,因而它们可以在相当大的直径时工作。此时额定的停留时间较长,矿流流径弯曲度较大。
One has precisely discussed the current scale-up formula and has refined and generalized a concept of recent import formulas, namely, the ratio of the media mass flow to the ore axial mass flow. Compare the number of collisions between ores and media and the average impact energy with a specific energy constant. It shows the similar fragmentation of a mill that is scaled up. A further result is that both the average mill rotation and the tortuosity of the mine flow path will be significantly reduced while the unit ore stays in the mill, whereas the axial flow will be very violent as the diameter of the mill increases increase. When the mill diameter reaches the critical range, especially for some of the coarser ores, these factors can lead to mill capacity constraints. Since most of the effective volume of the self-grinding machine is completely or mostly occupied by ores, they can work at relatively large diameters. At this point the rated residence time longer, larger flow path curvature.
