The ore crushing is the process to crush the big rock or to-be-crushed ore into the small one by means of the interaction between external forces and the internal molecular forces. In the ore dressing, ore crushing is generally divided into two kinds: coarse crushing and fine crushing.
Breaking ore is usually proceeding in the crusher. There are many kinds of crushers, but Jaw Crusher and Impact crusher are commonly used in the metal mining. Ore crusher and Stone crusher have also been applied in our country, but in general, the number was small. The jaw crusher and impact crusher are rotary cylinder with hollow shaft at both ends, and there are considerable number of steel bars and steel balls in the cylinder.
Crusher is the important role in the investment and production cost of ore dressing plant. Therefore, the basic task of ore crushing operation is to supply proper material for the beneficiation. Whether the crushing process is good or not directly influences the technical and economic data.
In ore processing plant, ore crushing is the essential material preparation stage befOre Beneficiation. Firstly, the vast majority of the ore to be crushed in the dressing plant is composed of the useful ore and gangue mineral especially the fine grain. Only by crushing and dissociating, the ore can be gathered with the current physical mineral processing. Secondly, any physical mineral processing is subject to the granularity, the excess granularity is that the useful ore and gangue mineral cannot be separated effectively.
Crush continues the ore crushing process and become the last process before ore separation. Crushing operations task is to take useful constituent completely or basically reached monomer separation, while at the same time if possible, avoiding excessive grind, provide the sorting operations appropriate particle size and concentration of selected ore pulp, and create the conditions for better recovery of useful component in ore. The sorting index is good or bad largely depends on the crush quality of the product. Therefore, the crush products should meet the different requirements on beneficiation methods in particle size to ensure that we can get the high quality concentrate and full recovery of useful minerals.
