Description
Technical field
The utility model relates to a kind of classifying lining board.
Background technology
Current cement grinding adopts ball mill to make whole grinding more.Material from bistrique to mill tail by the process of grinding, particle diameter progressively successively decreases.According to crushing material characteristic, require steel ball in mill also by the particle diameter regularity of distribution, to distribute from big to small to mill tail from bistrique.
For realizing above-mentioned requirements, ball mill often takes the form in minute storehouse to meet corresponding relation along axis, and because limited by factors, a minute storehouse can not be ad infinitum many, are often only divided into two to three storehouses.Therefore, behind minute storehouse, steel ball has only met corresponding relation roughly, and in same storehouse, due to the fluctuation in material filling and operation, the steel ball of size diameter, often in uniform contrary distribution even, is difficult to meet the corresponding requirement of sphere diameter and material particular diameter.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of classifying lining board is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of classifying lining board, be arranged on ball mill barrel inner surface, comprise body, body lower end has the arc surface matching with ball mill barrel inner surface, before arc surface, rear end respectively circular arc is connected with frontal plane and the back plane extending to the arc surface centre of gyration, the arc surface left end circular arc that makes progress is connected with the inclined-plane that tilts to upper right side, the arc surface right-hand member circular arc that makes progress is connected with vertical guide, described body upper end has inclined working, the height of inclined working, low side is connected with vertical guide circular arc with inclined-plane respectively, before inclined working, rear end is connected with back plane circular arc with frontal plane respectively, in inclined working, offer four from the high-end low side that leads to, cross section is the groove of arc, adjacent notches circular arc connects, groove two ends are connected with vertical guide circular arc with inclined-plane respectively, described arc surface is provided with rectangle pit, rectangle pit centres is provided with boss, boss center is provided with the step through-hole that runs through boss and inclined working.
Described step through-hole comprises the circular hole of boss side, elliptical aperture and the transitional pore of inclined working side, and circular hole is communicated with by transitional pore and elliptical aperture.
On described arc surface, offer two longitudinal flutings and two transverse concave grooves.
The beneficial effects of the utility model are: the utility model is arranged on ball mill barrel inner surface, in grinding machine axial slices, the inclined working of this classifying lining board is high-end towards mill tail, low side is towards bistrique, in inclined working, offer for promoting the groove of steel ball, during grinding machine work, after steel ball in inclined working enters and leaves a little, due to the support force of inclined working to steel ball, the direction that leaves of steel ball is partial to bistrique, because the steel ball varying in size has the inertia varying in size, in mill, steel ball also just distributes by the particle diameter regularity of distribution to mill tail from big to small from bistrique, thereby solved the problem proposing in background technology.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is that C in Fig. 1 is to view.
In figure: 1. arc surface; 2. inclined-plane; 3. vertical guide; 4. inclined working; 5. groove; 6. rectangle pit; 7. boss; 8. step through-hole; 9. longitudinal fluting; 10. transverse concave groove.
The specific embodiment
By reference to the accompanying drawings the utility model is further described now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1, 2, a kind of classifying lining board shown in 3, be arranged on ball mill barrel inner surface, comprise body, body lower end has the arc surface 1 matching with ball mill barrel inner surface, before arc surface 1, rear end respectively circular arc is connected with frontal plane and the back plane extending to arc surface 1 centre of gyration, the arc surface 1 left end circular arc that makes progress is connected with the inclined-plane 2 that tilts to upper right side, inclined-plane 2 is 75 ° with the inclination angle of horizontal plane, the arc surface 1 right-hand member circular arc that makes progress is connected with vertical guide 3, described body upper end has inclined working 4, the height of inclined working 4, low side is connected with vertical guide 3 circular arcs with inclined-plane 2 respectively, before inclined working 4, rear end is connected with back plane circular arc with frontal plane respectively, in inclined working 4, offer four from the high-end low side that leads to, cross section is the groove 5 of arc, adjacent notches 5 circular arcs connect, groove 5 two ends are connected with vertical guide 3 circular arcs with inclined-plane 2 respectively, described arc surface 1 is provided with rectangle pit 6, rectangle pit 6 centers are provided with boss 7, boss 7 centers are provided with the step through-hole 8 that runs through boss 7 and inclined working 4, adopt ball grinding machine lining board bolt this classifying lining board to be installed on ball mill barrel inwall by this step through-hole 8.
Described step through-hole 8 comprises the circular hole of boss 7 sides, elliptical aperture and the transitional pore of inclined working 4 sides, and circular hole is communicated with by transitional pore and elliptical aperture.
During for ease of installation classifying lining board, extrude the cement mortar in rectangle cavity 6, on described arc surface 1, offer two longitudinal flutings 9 and two transverse concave grooves 10.
Above-mentioned embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
