In China, the production of stone mineral is relatively high, for many of the mine, we all need a dedicated machine - hydraulic splitting machine. Hydraulic splitting machine is a relatively common quarry blocks of mining equipment, mainly for the mining of rock, the effect is very significant. Stone splitting, always rely on manual mason chisel to knock, not only inefficient, but also labor-intensive. In mining the need for a lot of large rocks for secondary disintegration, hydraulic splitting machine for secondary rock disintegration, low cost, high re-creation of value, a good solution to the problem of the disintegration of the stone twice. Since the compressive strength is far greater than most rock tensile and shear strength, the ratio is about l0: l. Therefore, from the internal split large rocks, one of the most labor-saving methods. Hydraulic fracturing machine of simple structure, easy to operate, safe, reliable, splitting speed, high efficiency, low cost, economic and social benefits significantly. The machine can replace the use of proven secondary blasting explosives, it is the ideal method for secondary breaking of large rocks. Hydraulic splitting machine work, the impact of friction is inevitable. Frictional resistance can be significantly reduced splitting force. Under normal circumstances, the actual splitting force is only 30% to 60% of the theoretical value. Under the same circumstances friction coefficient of friction with increasing force and working hydraulic fracturing increases. Reduce the frictional resistance is the main way to improve the performance of hydraulic splitting machine. To this end, in addition to efforts in friction material selection, heat treatment, surface treatment, it must also choose the right angle wedge. We believe that with the development and prosperity of urban construction stone industry, hydraulic splitting machine market potential is huge, has a broad application prospects.
