Abstract
The invention relates to a cabin separation grate plate for a ball mill. The cabin separation grate plate is provided with a grate plate body, wherein a semicircular groove is formed in the grate plate body; a positioning hole is formed in the groove; a chamfer is arranged at the opening of the groove; a plurality of sieving holes are uniformly formed in the surface of the grate plate body; the shape of the cross section of each sieving hole is trapezoid; and an inlet chamfer is arranged at the inlet of each sieving hole. The cabin separation grate plate has a simple structure, is convenient to use, and has high rigidity, high wearing resistance and long service life; and the previous high manganese steel casting thickness is reduced, so that the self weight of the whole ball mill is reduced and the production cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of ball mill grate plate used for isolating bin.
Background technology
Grate plate is used to protect cylindrical shell; cylindrical shell is made directly to impact from abrasive body and material and rub; also multi-form liner plate can be utilized to adjust the motion state of abrasive body simultaneously; to strengthen the pulverization of abrasive body to material; contribute to the mill efficiency improving grinding machine; increase yield, reduces metal consumption.
Along with the high speed development of cement industry, mill diameter specification is increasing, and grinding machine grate plate also there occurs great change thereupon, and grate plate structure is also developed into a kind of technical " device " all very strong with theoretical property by the protective lining that the past is simple.Often can find that liner plate exists concentrated wear when checking in cement grinding mill mill, hold-down nut is ground little, causes liner plate loose or dislocation to alter storehouse accident time serious.For storehouse accident altered by prevention grinding machine, each shutdown must check or the removable parts more serious aside-liner of wearing and tearing and grate plate set bolt, and certain manpower and materials waste, mill running cost raises relatively.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of ball mill grate plate used for isolating bin.
The technical solution adopted for the present invention to solve the technical problems is: a kind of ball mill grate plate used for isolating bin, there is grate plate body, described grate plate body is provided with semi-circular recesses, locating hole is provided with in groove, the opening part of groove is provided with chamfering, the surface of grate plate body is evenly provided with some sieve apertures, and the shape of the cross section of sieve aperture is trapezoidal, and the porch of sieve aperture is provided with entrance chamfering.
Further, described grate plate body adopts Wear-resistant alloy steel material to make.
Further, case hardness HRC >=50 of described grate plate body.
Further, the quantity of described sieve aperture is 4-20.
The invention has the beneficial effects as follows: structure of the present invention is simple, and easy to use, hardness is high, and wearability is high, long service life; Reduce original casting potassium steel thickness, whole ball mill is conducted oneself with dignity and reduces, significantly reduce production cost.
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 sectional view of B-B of the present invention.
1. grate plate bodies in figure, 2. groove, 3. locating hole, 4. chamfering, 5. sieve aperture.
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, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Fig. 1, a kind of ball mill grate plate used for isolating bin shown in 2, there is grate plate body 1, grate plate body 1 is provided with semi-circular recesses 2, locating hole 3 is provided with in groove 2, the opening part of groove 2 is provided with chamfering 4, the surface of grate plate body 1 is evenly provided with some sieve apertures 5, the shape of the cross section of sieve aperture 5 is trapezoidal, the porch of sieve aperture 5 is provided with entrance chamfering, on figure, unreceipted fillet and the curving of castings are R3-8mm, grate plate body 1 adopts Wear-resistant alloy steel material to make, case hardness HRC >=50 of grate plate body 1, the quantity of sieve aperture 5 is 4-20, anti-blocking is effective, structure is simple, easy to use, hardness is high, wearability is high, long service life, reduce original casting potassium steel thickness, whole ball mill is conducted oneself with dignity and reduces, significantly reduce production cost.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
