物料的可碎性及磨蚀性是选择破碎机类型应考虑的一个决定性因素。设计碎磨设备时应特别往意研究物料的这些特性。因为,即使是同类物料,有时也会表现出截然不同的特性。矿石晶体的内部结构及晶体之间的结合方式决定矿石的强度,也直接影响矿石的可碎性。在矿石中,二氧化硅的总含量决定矿石的磨蚀性,二氧化硅含量越高,对破碎机磨损越严重。应当指出,矿石的硬度不能决定其对破碎机的磨损程度。因为,难于破碎的硬矿石的磨
The crushability and abrasiveness of the material are a decisive factor to consider when choosing the type of crusher. Design grinding equipment should be particularly intended to study these characteristics of the material. Because, even the same kind of material sometimes shows very different characteristics. The internal structure of the ore crystal and the combination between the crystals determine the strength of the ore, but also directly affect the friability of the ore. In the ore, the total content of silica determines the abrasiveness of the ore. The higher the silica content, the more severe it is to the crusher. It should be noted that the hardness of the ore does not determine its degree of wear on the crusher. Because, hard to crush hard ore grinding
