Abstract
The invention relates to a compartment grate plate of a ball mill. The compartment grate plate of the ball mill comprises a grate plate body, grooves are uniformly formed in the end surface of the grate plate body; mounting holes are formed in the grooves; a plurality of sieve holes are formed in the central position of the grate plate body; the shape of the cross section of each sieve pore is trapezoidal; a chamfer is formed at the inlet of each sieve pore. The compartment grate plate of the ball mill is simple in structure, convenient to use, and good in wear resistance and blockage resistance, and also has the function of crushing; the sieve pores are not easily blocked; the production efficiency is improved; the resources are saved; the production cost is reduced.
Description
Technical field
The present invention relates to a kind of diaphragm grate plate for ball grinder.
Background technology
Grate plate is after material is broken, the key equipment sieving again, be applicable to the various ores of grinding and other material, be widely used in the industries such as building materials and chemical industry, cement, nitrate goods, New Building Materials, refractory material, chemical fertilizer, black or non-ferrous metal ore and glass ceramics.The working face of conventional grate plate is generally plane or cambered surface, in the time that inventory is large, easily blocks sieve aperture, affects production efficiency, can cause shutting down when serious.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, a kind of diaphragm grate plate for ball grinder that is difficult for blocking sieve aperture is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of diaphragm grate plate for ball grinder, there is grate plate body, on the end face of described grate plate body, be evenly provided with groove, in groove, be provided with installing hole, the center position of grate plate body is provided with some sieve apertures, being shaped as of the cross section of sieve aperture is trapezoidal, and the porch of sieve aperture is provided with chamfering.
Further, described grate plate body adopts antifriction alloy Steel material to make.
Further, the surface of described grate plate body is through Quenching Treatment, case hardness HRC >=50.
Further, the quantity of described sieve aperture is 4-8.
The invention has the beneficial effects as follows: the present invention is simple in structure, easy to use, wearability and anti-blocking performance are good, have the effect of pulverizing concurrently, and sieve aperture is difficult for stopping up, and enhances productivity, and economizes on resources, and reduces production costs.
Brief description of the drawings
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. groove, 3. installing hole, 4. sieve aperture, 5. chamfering.
Detailed description of the invention
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, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of diaphragm grate plate for ball grinder as shown in Figure 1, 2, there is grate plate body 1, on the end face of grate plate body 1, be evenly provided with groove 2, in groove 2, be provided with installing hole 3, the center position of grate plate body 1 is provided with some sieve apertures 4, being shaped as of the cross section of sieve aperture 4 is trapezoidal, the porch of sieve aperture 4 is provided with chamfering 5, the quantity of sieve aperture 4 is 4-8, and wearability and anti-blocking performance are good, have the effect of pulverizing concurrently, sieve aperture is difficult for stopping up, enhance productivity, do not need frequent replacing, reduce staff's labour intensity;
Grate plate body 1 adopts antifriction alloy Steel material to make, the surface process Quenching Treatment of grate plate body 1, and case hardness HRC >=50, long service life, economizes on resources.
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.
