[0002] The feeding chute is widely applied in the feeding link of the ball mill, which can guide the material to enter the ball mill cylinder uniformly and reduce the direct impact of the material on the feeding seal system. The size of the feeding amount of the ball mill system, the characteristics of the grinding material, the pH value of the ore pulp and the like all affect the service life of the feeding chute. The conventional feeding chute is basically of the integral casting type or the segmented welding type. If the working condition is too severe, the easily-damaged area of the lower wall of the feeding chute will be damaged and corroded in a short period of time, causing the condition of ore pulp leakage. Therefore, the user often adopts two ways to solve such problems, one is to replace the feeding chute as a whole, and the other is to repair the leakage position by welding. However, the cost of the whole replacement is high, and the repair by welding is difficult to operate and has poor effect. Usually, the ore pulp leakage will continue after the repair by welding is completed. SUMMARY

The access door sealing gasket is arranged between the chute assembly one and the access door, and the three are fastened through the bolt assembly.

[0005] The chute assembly one further comprises a steel plate and a square flange connecting plate one. Four steel plates are respectively welded on the four side outer walls of the lower opening area of the chute one. The outer side of the steel plate and the chute one is circumferentially angle welded, and the inner side is circumferentially single-side V-shaped welded. The mounting surface of the square flange connecting plate one is positioned at an angle of 45° with the horizontal feeding end surface of the chute one, and then is sleeved on the steel plate. The inner and outer sides of the contact area are circumferentially angle welded. After the welding is completed, the mounting surface is further processed.

[0006] The upper wall of the chute one protrudes a square platform, and a circle of internal thread holes are uniformly processed, which are used for mounting the access door.

[0007] The chute one is a casting part.

[0008] The chute assembly two comprises a chute two, a wear-resistant layer, a square flange connecting plate two, a connecting steel pipe and a handle, the inner wall of the chute two is uniformly hardfaced with the wear-resistant layer, the two end faces of the connecting steel pipe are respectively welded with the outer wall of the chute two and the square flange connecting plate two as a whole, wherein the processing range of the mounting surface of the square flange connecting plate two is 80mm in width and 4mm in depth, and the two handles are welded on the non-mounting surface thereof.

[0009] The chute two is a casting.
