Crushing method is the oldest mineral aggregate crushing method is the most widely used method of mineral aggregate crushing, broken machinery and the work it directly on the nugget component and make it broken, despite severe mechanical wear and product quality is not good, but it reliable and low cost make it broken in the broken field has been dominated, as is also the focus of research in mineral aggregate crushing method. Mechanical crushing method is broken by mechanical force to complete, broken machinery of force means nothing more than crushed, split, split-off, grinding, and shock. Crushing machine crushing force There are many ways, broken machinery determines the operating mode of each crusher broken often in a broken way of the main and supplemented by other methods, such as jaw crusher to crush the main cut with both force and ball mill grinding dominated by the impact and so on. Ore hardness, with great certainty of crushing force of resistance at failure. Ore brittle, broken and split the role of resistance poor, the use of split and break easily broken when the ore block. Ore brittle, easily lead to excessive grinding crushed under. Ore minerals are different polymers, not even the mechanical properties of the ore block, there are many vulnerable side on the mechanics, so the poor against shocks, which, with the energy of broken ore will be the lowest. Therefore, only from the mechanical nature of the ore, crushed and broken ore used unreasonable, broken and split by crushing ore more advantageous. But in the actual crushing machinery, crushing force of the most easy to implement, can only be broken and split the role with only a broken rack Liner staggered to achieve, and the large role of mineral hardness makes it difficult to split, only been on the low hardness coal blocks can be split high-stronger tip broken broken rack. Therefore, the nature of the different ores choose the appropriate way to crushing the broken an important principle that means crushing force to adapt to the nature of the ore, will have good crushing effect. Of hard minerals, should be used with the impact bending to breaking it, as by grinding, the machine certainty of serious wear and tear. For brittle ore, bend and split more favorable, such as by grinding, the product will be too much in too small powder. For greater toughness and viscous minerals, easily broken by the grinding method, the use of a shock and bending are not good and so on. Diverse nature of the ore, the nature of the ore used for the appropriate way of crushing force is an important way to improve crushing efficiency.
