Abstract
The utility model discloses improvement of a feed and discharge port lining structure for a ball mill. The feed and discharge port lining structure comprises the ball mill; cover plates are arranged on a feed port and a discharge port of the ball mill through linings of cylinder flanges respectively; the feed and discharge port lining structure is characterized in that the linings are steel plates; the steel plates and the cover plates are overlapped and then are integrally fixed with the cylinder flanges; and edges of the feed port and the discharge port of the ball mill are provided with lubricating oil nozzles respectively. The feed and discharge port lining structure is reasonable in structural design, can bear certain shearing force due to the structural design of the steel plates used as the linings, is not needed to be replaced frequently, improves working efficiency and reduces production cost.
Description
Technical field
The utility model relates to a kind of improvement of ball mill partial structurtes, relates in particular to a kind of improvement of ball mill charging and discharging mouth bush structure.
Background technology
Ball mill is after material is broken, the key equipment of pulverizing again.Ball mill is applicable to the various ores of grinding and other material, is widely used in ore dressing, and industries such as building materials and chemical industry can be divided into two kinds of grinding modes of dry type and wet type.No matter be dry type and two kinds of grinding modes of wet type, when ball mill was worked, the material in the rotating part of ball mill sealing wore and tore in rotation; Can produce certain shearing force to discharging opening and charging aperture simultaneously, mostly install between existing ball mill barrel flange and discharging opening and the charging aperture flange, owing to the charging and discharging lining is a kind of structure of beam type in cylindrical shell through rubber seal; Because rubber blanket is to flexibly connect,, often rupture in the use so fastening bolt is influenced by shearing force in the ball mill operation process; Need often to change; And lining can be subjected to displacement along axis direction, influences operating efficiency simultaneously, has improved production cost.
The utility model content
The purpose of the utility model is in order to remedy the deficiency of prior art, a kind of improvement of ball mill charging and discharging mouth bush structure to be provided, because the charging and discharging lining is a kind of structure of beam type in cylindrical shell; In the use because rubber blanket be to flexibly connect; So fastening bolt is influenced by shearing force in the ball mill operation process, often fracture needs often to change; Influence operating efficiency simultaneously, improved production cost.
The utility model is realized through following technical scheme:
A kind of improvement of ball mill charging and discharging mouth bush structure; Include ball mill; The charging aperture of said ball mill and discharging opening are equipped with cover plate through shell flange, lining respectively; It is characterized in that: said lining is a steel plate, and said steel plate and cover plate stack back are one with the shell flange fixed installation, and the charging aperture of said ball mill and the edge of discharging opening are respectively equipped with the lubricating oil nozzle.
Described steel plate is circular, and the steel plate size cooperates with shell flange, is installed on the shell flange through several bolt between said steel plate and the cover plate.
The utility model is through the structural design of steel plate lining, when ball mill is worked, though the material in the ball mill rotating part can produce certain shearing force to discharging opening and charging aperture; Because steel plate endurance is strong, has guaranteed that bolt can not receive bigger shearing force, therefore do not need frequent replacing; Improved operating efficiency; Through the lubricating oil nozzle gap between steel plate and the shell flange is lubricated sealing simultaneously, has guaranteed the normal operation of producing, reduced production cost simultaneously.
The utility model has the advantages that:
The utility model reasonable in design through the structural design of steel plate lining, can be born the influence of certain shearing force, does not need frequent replacing, has improved operating efficiency, has reduced production cost.
Description of drawings
Fig. 1 is the utility model structure cutaway view.
The specific embodiment
Referring to accompanying drawing; A kind of improvement of ball mill charging and discharging mouth bush structure; Include ball mill 1, the charging aperture of ball mill 1 and discharging opening are equipped with cover plate 4,5 through shell flange 2,3 linings respectively, and lining is a steel plate 6; Steel plate 6 is one with cover plate 4,5 stack backs and shell flange 2,3 fixed installations, and the charging aperture of ball mill 1 and the edge of discharging opening are respectively equipped with lubricating oil nozzle 7,8; Described steel plate 6 is circular, and the steel plate size cooperates with shell flange 2,3, said steel plate 6 and cover plate 4, is fixedly mounted on the shell flange 2,3 through several bolts 9 respectively between 5.
Claims (2)
1. the improvement of a ball mill charging and discharging mouth bush structure; Include ball mill; The charging aperture of said ball mill and discharging opening are equipped with cover plate through shell flange, lining respectively; It is characterized in that: said lining is a steel plate, and said steel plate and cover plate stack back are one with the shell flange fixed installation, and the charging aperture of said ball mill and the edge of discharging opening are respectively equipped with the lubricating oil nozzle.
2. the improvement of a kind of ball mill charging and discharging mouth bush structure according to claim 1; It is characterized in that: described steel plate is for circular; And the steel plate size cooperates with shell flange, is installed on the shell flange through several bolt between said steel plate and the cover plate.
