Abstract
The invention relates to a grate plate for a ball mill. The grate plate comprises a grate plate body, two ends of the grate plate body are respectively provided with a mounting hole, the center position of the grate plate body is provided with a positioning hole, the center position of the bottom surface of the grate plate body is provided with an oval groove, the upper surface of the grate plate body is provided with a groove, the grate plate body is provided with a plurality of grate holes, and the cross section of each of the grate holes is trapezoidal in shape. The grate plate has the advantages of simple structure, use convenience, safety, and reliability, and materials pass the grate plate with low resistance, can rapidly pass, does not deposit on the grate plate and thus does not block the grate holes, so the workload of laborers is reduced, time and labor are saved, the production efficiency is improved and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of 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, and the material that is less than castor hole falls into rapidly feed bin, and the material and the foreign material that are greater than castor hole are stayed on sieve nest, after shutdown, by manually removing, increases workman's workload, wastes time and energy, and reduces production 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 ball mill grate plate of enhancing productivity is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of 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 center position of the bottom surface of grate plate body is provided with oval-shaped groove, the upper surface of grate plate body is provided with groove, is provided with some combs hole on grate plate body, and the cross sectional shape in comb hole is trapezoidal.
Further, described grate plate body be shaped as fan-shaped.
Further, described grate plate body is just made with high manganese steel material.
Further, the opening part in described comb hole is provided with chamfering.
Further, the quantity in described comb hole is 10-20.
Further, the surface of described grate plate body is through heat treatment, and case hardness is HRC >=46 °.
The invention has the beneficial effects as follows: the present invention is simple in structure, easy to use, safe and reliable, the current resistance of material is less, can cross grate plate by Rapid Flow, can on grate plate, not deposit, castor hole is difficult for occurring choking phenomenon, reduces labourer's workload, time saving and energy saving, enhance productivity, reduce production costs.
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 left view of the present utility model;
Fig. 3 is the cutaway view of B-B of the present utility model.
1. grate plate bodies in figure, 2. installing hole, 3. locating hole, 4. oval-shaped groove, 5. groove, 6. 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 ball mill grate plate as shown in Figure 1, 2, 3, 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, and the center position of the bottom surface of grate plate body 1 is provided with oval-shaped groove 4, and the upper surface of grate plate body 1 is provided with groove 5, on grate plate body 1, be provided with some combs hole 6, the cross sectional shape in comb hole 6 is trapezoidal, and the opening part in comb hole 6 is provided with chamfering, and the quantity in comb hole 6 is 10-20.
Being shaped as of grate plate body 1 is fan-shaped, and grate plate body 1 is just made with high manganese steel material, and the surface of grate plate body 1 is through heat treatment, case hardness is HRC >=46 °, easy to use, safe and reliable, the current resistance of material is less, can cross grate plate by Rapid Flow, can on grate plate, not deposit, castor hole is difficult for occurring choking phenomenon, reduce labourer's workload, time saving and energy saving, enhance productivity, reduce production costs.
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.
