由于原矿硬度较低,致使自磨机磨矿能力下降。通过调整自磨机的自返筛筛缝和补加一定的磨矿介质,变自磨工艺为半自磨工艺,使自磨机磨矿能力大大提高,两段磨矿能力基本达到平衡。 Due to the lower hardness of raw ore, resulting in self-grinding machine grinding capacity decline. By adjusting the self-return screen sieve seam of the mill and adding a certain amount of grinding media, the grinding process is changed into the semi-autogenous grinding process so that the grinding capacity of the self-grinding mill is greatly improved and the grinding capacity of the two sections is basically balanced.
