对破碎和磨矿过程中的各种力的破碎作用进行了比较,研究了单位能耗与所采用的磨矿方法的关系和各类型原料破碎能耗的效率。分别对石灰石、砂岩、石英岩和岩盐进行了实验。采用的磨矿设备是VM 3实验室型磨矿机,莱奇公司KH-1磨蚀型磨机和具有特殊构造的喷砂水枪,在研钵中的冲击磨头是经过研磨并能自由坠落的圆柱体,其重量为11.22公斤。 The crushing effect of various forces in the process of crushing and grinding was compared. The relationship between unit energy consumption and the grinding method adopted and the efficiency of crushing energy consumption of various types of raw materials were studied. Limestone, sandstone, quartzite and rock salt were tested respectively. The grinding equipment used is the VM 3 laboratory mill, the KH-1 abrasion mill from Ridge and the sandblasting gun with a special construction, the impact grinding head in the mortar being ground and free to fall Cylinder, its weight is 11.22 kg.
