Summary of the invention
The applicant is at the mill unreasonable structure of above-mentioned existing rubber grinding machine, cause grinding and yield poorly, shortcomings such as equipment is fragile, provide a kind of rational in infrastructure, grind the mill structure of rubber grinding machine efficiently, effectively raise grinding output, reduce the heat that produces when grinding, prolonged equipment life.
The technical solution adopted in the present invention is as follows:
A kind of mill structure of rubber grinding machine, comprise movable grinding disc and fixed millstone, the matrix end face of movable grinding disc and fixed millstone is the sphere of scrobicula, matrix arranged in arrays at the mill end face has skive blade, its highly gradient be higher than mill sphere end face, be that blade is higher near the head protrusion matrix end face of mill central authorities, blade is lower near the end protrusion matrix end face at mill edge.It is further characterized in that:
The central authorities of movable grinding disc are provided with cross and grind cutter, and it highly all protrudes from the end face of movable grinding disc matrix.
Mill end face of the present invention is uniform spherical curve, therefore can not cause material to stop up because of the abrupt change of cross-section; Carbide chip near the gradual change of mill central authorities to edge be higher than mill sphere end face, so each part of blade all effectively participated in grinding operation, wearing and tearing quite after the long-term work; The present invention is shallow and even in the sphere depression of movable grinding disc middle part setting, therefore can not occur causing local wall thickness to cross living the breaking and damage of small property owing to being provided with cavity; The middle part is provided with the cross cutter and can not only discharges material effectively and uniformly, and can effectively improve grinding efficiency.
