Abstract

The utility model discloses a rubber lining plate lifting strip of a ball grinding mill, which is formed by compounding rubber and a metal framework, wherein the metal framework is fused in the rubber and comprises a framework body with a groove, wherein two sides of the framework body are respectively welded and fixed with a reinforcing plate with length equal to that of the framework body, the reinforcing plates are embedded in the rubber to play a role in fastening, and the metal framework can be well fixed, so that a composite structure between the rubber and the metal framework is more firm.

Description

The ball mill rubber lining promotes bar

Technical field

The utility model relates to a kind of wear-resisting rubber products, more particularly, relates in particular to a kind of mine and promotes bar with the rubber lining that is suitable in the large-size ball mill equipment.

Background technology

Ball grinding machine lining board is to be used for protecting ball mill barrel; Make it avoid abrasive body and directly impact and friction of material; Multi-form liner plate also capable of using is adjusted the motion state of abrasive body simultaneously; To strengthen abrasive body to the material grinding effect, help to improve the crush efficiency of grinding machine, increase output, reduce metal consumption.

Rubber lining is a liner plate device commonly used in the present large-size ball mill equipment; Mainly comprise and promote bar, shell liner, securing member and nut; Promoting bar in adjacent two shell liner joints with one pushes down; Then securing member is slipped in the groove that promotes the bar skeleton, passing behind the ball mill barrel again, fastening nut reaches the purpose that shell liner is installed.But combining between the metallic framework in existing lifting bar and the rubber is firm inadequately; The obstruction that has no between the two is renderd a service; The phenomenon that skeleton separates with rubber possibly occur after long-time the use, thereby cause liner plate to come off, influence the service life and the production efficiency of ball mill.

The utility model content

The purpose of the utility model is the deficiency to above-mentioned prior art, provides the firm ball mill rubber lining of a kind of composite construction to promote bar.

For realizing above-mentioned purpose; The ball mill rubber lining that the utility model provided promotes bar; Be composited by rubber and metallic framework, said metallic framework is blended in the rubber, comprises the skeleton body of being with groove; It is the stiffener of 3～5cm that the both sides of said skeleton body respectively are welded with a, width isometric with the skeleton body, and said stiffener embeds in the rubber.

Said stiffener is symmetrically welded on the side of skeleton body, and is vertical each other with the side.

Said stiffener is symmetrically welded on the end face of skeleton body, fits with summit portion.

The utility model is through fixing stiffener isometric with the skeleton body of each welding on the both sides of skeleton body; This stiffener embeds in the rubber; Play fastening effect, better the fixing metal skeleton makes that the composite construction between rubber and metallic framework is more firm.

Description of drawings

Fig. 1 is the schematic cross-section that the utility model ball mill rubber lining promotes bar;

Fig. 2 and Fig. 3 are respectively the sketch mapes of the metallic framework of two kinds of different structures.

Among the figure: 1-rubber; The 2-metallic framework; 21-skeleton body; The 22-groove; The 23-stiffener.

The specific embodiment

Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.

Consult shown in Figure 1; The utility model ball mill rubber lining promotes bar, is composited by rubber 1 and metallic framework 2 (normally steel skeleton), and said metallic framework 2 is blended in the rubber 1; Comprise the skeleton body 21 of being with groove 22; The both sides of said skeleton body 21 respectively are welded with a stiffener 23 21 isometric with the skeleton body, that width is 3～5cm, and said stiffener 23 embeds in the rubber 1, plays fastening effect; Better fixing metal skeleton 2 makes that the composite construction of 2 of rubber 1 and metallic frameworks is more firm.

Fig. 2 and Fig. 3 have provided the metallic framework of two kinds of different structures respectively, and metallic framework shown in Figure 2 is that stiffener 23 is symmetrically welded on the side of skeleton body 21, and is vertical each other with the side.Metallic framework shown in Figure 3 is that stiffener 23 is symmetrically welded on the end face of skeleton body 21, fits with summit portion.

Claims

1. a ball mill rubber lining promotes bar; Be composited by rubber and metallic framework; Said metallic framework is blended in the rubber; Comprise the skeleton body of being with groove, it is characterized in that: it is the stiffener of 3～5cm that the both sides of said skeleton body respectively are welded with a, width isometric with the skeleton body, and said stiffener embeds in the rubber.

2. ball mill rubber lining according to claim 1 promotes bar, and it is characterized in that: said stiffener is symmetrically welded on the side of skeleton body, and is vertical each other with the side.
