Hydraulic ball Press Machine Working Principle:Motive power will transmit to two rollers through the reducer synchronously and make them rotate oppositely. Materials enter into ball mode naturally, with rollers rotation, pressure of materials bearing becomes larger. When arriving at two rollers contact point, materials bearing pressure reaches peak. Under the tremendous pressure, materials become ball shape from powder shape. Hydraulic ball press machine can press all kinds of ore powder, metal powder, coal powder, coke powder and other materials into ball shape. Because of mandatory squeeze of rollers, the final product features of high-density, high strength, high hardness. Moreover, adopting 650 mm wear resistance materials rollers, which improve hydraulic ball press machine service life effectively.After thirty years research, the company has developed 1-50000 tons mechanical shaping machine & 3-100000 tons hydraulic shaping machine, more than 10 series, over 20 kinds of shaping machinery and equipment. This series of industrial shaping equipment is not only suitable for industrial gas-making, boiler coal, cold pressing coke, ignition coal, civil coal, but also applies to civil metallurgy, refractory, and pharmaceutical materials, etc various molding. Hydraulic protection device, high pressure oil enters into hydraulic cylinder by hydraulic pump, so that the piston axial displacement. When feeding too much or to entering metal materials, the hydraulic cylinder piston rod overloads, the hydraulic pump will be shut down, the accumulator will have a dampening effect for pressure change, the relief valve will open the oil return, the piston rod displacement increasing the gap between rollers so that the hard object can through rollers, the system back to normal, then can protect rollers from damaging. The unit can adjust the pressure according to the requirements of ball density, production is flexible.
