Abstract
The utility model relates to a special-shaped energy-saving ball mill cylinder body which belongs to mining machinery. The ball mill cylinder body has the structure that the surface of the cylinder body is provided with a port for charging medium or maintenance, both ends of the cylinder body are respectively provided with an end closure the inner side of each end closure is provided with a metal composite magnetic liner, and the cylinder body presents a triangle oblong shape; the exterior of the cylinder is welded with a steel bar framework, and the blanks of the steel bar framework are filled with magnetic blocks which are nonmetal magnetic polyurethane magnetic blocks or rubber magnetic blocks. The special-shaped energy-saving ball mill cylinder body has the advantages that the cylinder body breaks traditional machine type and has simple structure and easy manufacture; the energy is saved by 30 percent in the same production capacity conditions, and the production cost is reduced; the weight of the cylinder body is greatly reduced, and the labor intensity is lightened; the ball mill cylinder body has high work efficiency, long service life and strong practicality.
Description
Technical field
The utility model relates to the mining machinery class, and particularly a kind of assembly that is applicable to one section ball mill refers to a kind of special-shaped energy-saving ball mill cylindrical shell especially.
Background technology
As everyone knows, the cylindrical shell of ball mill is the important composition parts of ball mill, and it is made of cylindrical shell, shell liner, end cap, end cap liner plate, throwing medium/access hole, sealing gasket and holding screw.In order to protect cylindrical shell, increase the service life of ball mill, liner plate is installed in cylindrical shell.Because during the ball mill running, liner plate will be subjected to impact wear, the fatigue wear of medium and material and shear wearing and tearing etc., and had a strong impact on the service life of ball mill, also be simultaneously the main expenditure that the mine produces.The service life of general one section ball grinding machine lining board is about 8 months, the service life of two sections ball grinding machine lining boards is about 15 months, need the periodic replacement liner plate, cost height not only, influence production efficiency, and consumed great deal of steel, and according to the preliminary statistics, about 200,000 tons of the annual ball grinding machine lining board that consumes of China.
In recent years; occurred nonmetal magnetic polyurethane and rubber lining on the market, it forms protective layer by magnetic force adsorbing medium fragment, iron powder on the liner plate surface, though be better than metal backing at some aspect of performance; but the slip ability easily scratches and tears magnetic liner plate.
At present more advanced is composite metal/nonmetal magnetic liner plate, though it has overcome the shortcoming that above-mentioned ball mill barrel exists, complex structure is made loaded down with trivial details and cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of special-shaped energy-saving ball mill cylindrical shell, has solved traditional ball mill circular cylinder body structure, adds large cylinder for output, wastes energy, problem such as cost height.
The technical solution of the utility model is: special-shaped energy-saving ball mill drum surface is provided with throwing medium/access hole, and two ends are respectively equipped with end cap, and the inboard of this end cap is provided with the metal composite magnetic liner plate, and this cylindrical shell is the triangle ellipse; Cylindrical shell outside weldings steel bar skeleton is filled magnetic patch in the space of this steel bar skeleton, this magnetic patch is nonmetal magnetic polyurethane magnetic patch or rubber magnetic patch.
Another purpose of the present utility model is to provide a kind of special-shaped energy-saving ball mill cylindrical shell, and this drum surface is provided with throwing medium/access hole, and two ends are respectively equipped with end cap, and the inboard of this end cap is provided with the metal composite magnetic liner plate, and this cylindrical shell is the triangle ellipse; The inside of cylindrical shell is provided with alloy lining or composite metal/nonmetal magnetic liner plate.
Advantage of the present utility model is: the type that breaks traditions, and simple in structure, make easily; Energy-conservation 30% under the equal condition of production capacity, reduced production cost simultaneously; Cylindrical shell weight significantly alleviates, and labour intensity is low; Machine works efficient height, long service life, practical.

Fig. 1 looks schematic diagram for master of the present utility model;
Fig. 2 does not have the structure cross-sectional schematic of liner plate for the utility model;
Fig. 3 has the structure cross-sectional schematic of liner plate for the utility model.
The specific embodiment:
Shown in accompanying drawing 1 and accompanying drawing 2, the utility model abnormity energy-saving ball mill cylindrical shell 1 surface is provided with throwing medium/access hole 5, and two ends are respectively equipped with end cap 6, and the inboard of this end cap 6 is provided with metal composite magnetic liner plate 3, and this cylindrical shell 1 is the triangle ellipse; Cylindrical shell 1 outside weldings steel bar skeleton 2 is filled magnetic patch 4 in the space of this steel bar skeleton 2, this magnetic patch 4 is nonmetal magnetic polyurethane magnetic patch or rubber magnetic patch.
Shown in accompanying drawing 1 and accompanying drawing 3, the utility model abnormity energy-saving ball mill cylindrical shell 1 surface is provided with throwing medium/access hole 5, and two ends are respectively equipped with end cap 6, and the inboard of this end cap 6 is provided with metal composite magnetic liner plate 3, and this cylindrical shell 1 is the triangle ellipse; The inside of cylindrical shell 1 is provided with alloy lining or composite metal/nonmetal magnetic liner plate 7.
During use, magnetic force is adsorbed on cylinder inboard wall with 1 medium disintegrating slag, iron powder in the tube, thus protection cylindrical shell 1.This cylindrical shell 1 can adopt nonmagnetic high-abrasive materials such as potassium steel.
