Abstract
The utility model relates to a non-lining board type ball mill tube body, which belongs to the mining machine. A compound-type lining board is not needed to be manufacture, the surface of the tube body of the ball mill is provided with a medium-casting hole/an access hole, and both ends are respectively provided end caps, the inner sides of the end caps are provided with metal compound magnetic lining boards, a steel-bar framework is welded out of the tube body, a magnetic patch is arranged in the blank of the framework, and the magnetic patch can be non-metal magnetic polyurethane magnetic patch or a rubber magnetic patch, and medium slag and iron dust in the tube body are adsorbed on the inner wall of the tube body by magnetic force, thereby protecting the tube body. The utility model has the advantages of simple structure, easy manufacture, light tube body, high working efficiency, long service span and strong pracaticability, which breaks a traditional machine type, lowers the production cost, and lightens the labor intensity.
Description
Technical field
The utility model relates to the mining machinery class, and particularly a kind of ball mill assembly refers to a kind of linerless board-like ball mill barrel 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 magnetic patch, 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 linerless board-like ball mill barrel, has solved traditional ball mill barrel complex structure, has made problems such as loaded down with trivial details and cost height.
The technical solution of the utility model is: need not make compound liner plate, the ball mill barrel 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; This cylindrical shell outside weldings steel bar skeleton is filled magnetic patch in the space of this skeleton, this magnetic patch can be nonmetal magnetic polyurethane magnetic patch or rubber magnetic patch, and magnetic force is adsorbed on cylinder inboard wall with medium disintegrating slag, the iron powder in the tube, thus the protection cylindrical shell.
Advantage of the present utility model is: the type that breaks traditions, and simple in structure, make easily, reduce production costs; Cylindrical shell weight significantly alleviates, and is energy-conservation, alleviated labour intensity; Machine works efficient height, long service life, practical.
Description of drawings:
Fig. 1 looks schematic diagram for master of the present utility model;
Fig. 2 is a cross-sectional schematic of the present utility model.
The specific embodiment:
Shown in accompanying drawing 1 and accompanying drawing 2, the surface of the linerless board-like ball mill barrel 1 of the utility model 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; This cylindrical shell 1 outside weldings steel bar skeleton 2 is filled magnetic patch 4 in the space of this skeleton 2, this magnetic patch 4 can be nonmetal magnetic polyurethane magnetic patch or rubber magnetic patch, and 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.
