Four Kinds Rock Crusher and Things Should Notice When Buying

While using crusher to crush ores also can choose rock crusher according to the degree of hard rock, avoiding causing the waste of resources. As for some minerals with extreme hardness, such as quartzite rocks, sandstone, marbles, shale and sandstone ore, which are fine and solid, so you should choose crushing equipment with high crushing capacity like jaw crusher. Using other crushers which use hammer and grinding way will make the machine suffer severe wear and tear, and causing not excellent effect. So we should choose the appropriate crusher, and jaw crusher is the best choice.Rock crusher is mainly about the following four kinds:1. The explosion ShatteredThe usage of explosive or other explosive moments of the great energy released and rock crushing, at present it is the most widely used and most effective technology.2. Mechanical CrushingCutting, punching chisel, crushing, grinding are the general four ways. Rock crusher, rock tools into the rock, and within the tool moving in front of the rock mass, is a dense core. Around the dense nuclear broken body produces a large crack. Mechanical crushing is not widely used in hard rock. It is the main reason of the tool wear. Rock crushing is mainly depends on the degree of wear and tear of rock within the content of hard minerals and particle size.3. Water Jet BreakingIt is divided into low pressure large flow and high pressure small flow. The former pressure does not exceed 2 x 107 pas, is used in hydraulic mining or coal mining. The pressure can reach more than several hundred million palmer, are used to crushing rocks. In addition, it also developed the pulsed jet technology, which can effectively break solid rock without a lot of power. At present the highest instantaneous pressure, has amounted to 5.6G Pa. High pressure water jet breaking rock, high energy consumption of the mechanical structure is complex, much as the machine and auxiliary means of rotary drills and crushing rock in the open air.4.
