众所周知,固体的分散度和其它结构及物理-化学性质会被磨矿机的机械应力所改变。由于结构缺陷以比应力形式集中在薄表面层上,机械活化的作用不仅对高分散度,而且对颗粒粒度(浮选粒度)都是显著的。石英、锡石和其它矿物实例显示,可同时得到可浮性的恶化和改善。 It is well known that the degree of dispersion of solids and other structural and physico-chemical properties can be altered by the mechanical stress of the mill. Due to the structural defects being concentrated on thin surface layers in a stress-specific manner, the effect of mechanical activation is significant not only for high dispersibility but also for particle size (flotation particle size). Quartz, cassiterite and other mineral examples show that both fouling and deterioration can be achieved.
