Description
Technical field
The utility model relates to the compound grate plate of a kind of ball mill.
Background technology
Grate plate is generally placed on groove top, ore deposit, mainly prevent because freezing or rust joint stops up ore deposit groove lower part outlet after becoming the bits shape of agglomerate or lump material to enter ore deposit groove, due to the dither of grate plate, preventing that bulk materials from entering ore deposit groove simultaneously, the normal material that is less than sieve aperture can fall into rapidly ore deposit groove, can also play the large caking of some adhesion strengths loose, the effect of fragment, be desirable groove top, ore deposit equipment, be widely used in the industries such as electric power, coal, mine, building materials, metallurgy, chemical industry.The comb hole of conventional grate plate is generally perpendicular to plate body plane layout, in the time that inventory is large, easily blocks comb hole, 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, provide a kind of ball mill of enhancing productivity compound grate plate.
The utility model solves the technical scheme that its technical problem adopts: the compound grate plate of a kind of ball mill, there is grate plate body and comprise front comb board and back comb board, the two ends of described grate plate body are provided with installing hole, between front comb board and back comb board, being provided with offset deviation is 3-6mm, on grate plate body, be provided with some combs hole, the shape of cross section in comb hole is trapezoidal.
Further, the quantity in described comb hole is 10-25.
Further, the surface of described grate plate body is through heat treatment, and case hardness is HRC >=46 °.
Further, between described comb hole and grate plate body plane, be provided with chamfering.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, prevent feed blocking comb hole, and screening effect is good, and charging is fast, is difficult for blocking comb hole, enhances productivity, and reduces production costs.
