Abstract
The invention relates to an anti-abrasive grate plate for ball mills. The grate plate comprises a grate plate body, wherein mounting holes are formed in two ends of the grate plate body; a locating hole is formed in the central position of the grate plate body; an elliptic groove is arranged at a position, concentric with the locating hole, in the bottom of the grate plate body; a plurality of grate holes are formed in the grate plate body; the sections of the grate holes are trapezoid. The grate plate disclosed by the invention is simple in structure, convenient to use, safe and reliable, good in abrasive resistance and little in abrasion loss and does not need to be replaced frequently, so that the production cost is reduced and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of anti abrasive ball mill grate plate.
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, dither due to 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, to the large caking of some adhesion strengths, can also play 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 operation principle of grate plate is that vibrating motor drives dither, the material that is less than castor hole falls into rapidly feed bin, the material and the foreign material that are greater than castor hole are stayed on sieve nest, in use resistance is larger for the grate plate using now, easily stop up, wearing and tearing are simultaneously larger, need to often change, improve production cost, reduce operating efficiency.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, a kind of anti abrasive ball mill grate plate reducing costs is provided.
The technical solution adopted for the present invention to solve the technical problems is:: a kind of anti abrasive ball mill grate plate, there is grate plate body, the two ends of described grate plate body are provided with installing hole, the center position of grate plate body is provided with locating hole, the bottom of grate plate body is provided with oval recess with the concentric place of locating hole, on grate plate body, be provided with some combs hole, the cross sectional shape in comb hole is trapezoidal.
Further, described grate plate body be shaped as fan-shaped.
Further, the surface of described grate plate body is through heat treatment, and case hardness is HRC >=46 °.
Further, the opening part in described comb hole is provided with chamfering.
The invention has the beneficial effects as follows: the present invention is simple in structure, easy to use, safe and reliable, anti-wear performance is good, and wear extent is little, without frequent replacing, reduces production costs, and enhances productivity.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the cutaway view of B-B of the present invention.
1. grate plate bodies in figure, 2. installing hole, 3. locating hole, 4. oval recess, 5. comb hole.
The specific embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
A kind of anti abrasive ball mill grate plate as shown in Figure 1, 2, there is grate plate body 1, the two ends of grate plate body 1 are provided with installing hole 2, the center position of grate plate body 1 is provided with locating hole 3, the bottom of grate plate body 1 is provided with oval recess 4 with the concentric place of locating hole 3, on grate plate body 1, be provided with some combs hole 5, the cross sectional shape in comb hole 5 is trapezoidal, and the opening part in comb hole 6 is provided with chamfering;
Being shaped as of grate plate body 1 is fan-shaped, manufactures simply, and easy to use, the surface of grate plate body 1 is through heat treatment, and case hardness is HRC >=46 °, safe and reliable, and anti-wear performance is good, and wear extent is little, without frequent replacing, reduces production costs, and enhances productivity.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
