Description
Technical field
The utility model relates to a kind of grate plate used for isolating bin.
Background technology
Grate plate is for protecting cylindrical shell; make cylindrical shell avoid abrasive body and directly impact and friction of material; also can utilize multi-form liner plate to adjust the motion state of abrasive body simultaneously; to strengthen the pulverization of abrasive body to material; contribute to improve the mill efficiency of grinding machine; increase output, reduce metal consumption.
Be accompanied by the high speed development of cement industry, mill diameter specification is increasing, and great variation has also occurred grinding machine grate plate thereupon, and grate plate structure also develops into all very strong " devices " of a kind of technical and theoretical property by simple protective lining of past.Ball mill is after material is broken, then the key equipment of pulverizing.Be applicable to the various ores of grinding and other material, be widely used in ore dressing, the industries such as building materials and chemical industry.Grate plate is after material is broken, then the key equipment sieving, and is applicable to the various ores of grinding and other material, is widely used in ore dressing, the industries such as building materials and chemical industry.The working face of conventional grate plate is generally plane or cambered surface, when inventory is large, easily blocks sieve aperture, affects production efficiency, can cause shutting down when serious.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of grate plate used for isolating bin of good airproof performance is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of grate plate used for isolating bin, there is grate plate body, on the surface of described grate plate body, surrounding is provided with semi-circular recesses, the opening part of groove is provided with chamfering, in groove, be provided with positioning through hole, the center position of grate plate body is evenly provided with sieve aperture, the top of grate plate body is evenly provided with short bar shaped screen hole, grate plate body middle part is provided with strip sieve aperture, the bottom of grate plate body is provided with medium length type sieve aperture, the shape of cross section of sieve aperture is trapezoidal, and the porch of sieve aperture is provided with chamfering.
The radius of the chamfering of further, stating is set to R8-10mm.
Further, described grate plate body adopts antifriction alloy Steel material to make.
Further, the surface hardening of described grate plate body, case hardness HRC >=50.
Further, the quantity of described sieve aperture is 4-20.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, simple installation, and good sealing effect, long service life, wearability and anti-blocking performance are good, have the effect of pulverizing concurrently, reduce production costs.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
