Abstract
The utility model relates to a partition plate and discharge screen of a ball mill, which comprises a circular baffle formed by the combination of a plurality of sections of sheet plates with gate holes; cane-shaped connecting pieces are arranged at the joints of the sheet plates and the inner wall of a roller of the ball mill respectively; one end of each connecting piece is connected with the inner wall of the roller; and the other ends of the connecting pieces are connected with each other through bolt through holes as well as bolt holes and nuts on the joint of connecting bolts and the sheet plates. The device provided by the utility model not only has high intensity and good impact resistance, also has long service life and is favorable for saving production cost.
Description
Technical field
The utility model relates to a kind of ball mill partition panel and discharging web plate.
Technical background
Ball mill is the most general a kind of milling apparatus of commercial Application.Be typically provided with 1～2 layer partition panel in the cylindrical ball mill, ball mill is divided into 2～3 storehouses.As shown in Figure 1, existing partition panel and discharging web plate generally are the fan-shaped board material splice that turns shape by some and form, and an end of this sheet material is fixedly connected on the ball mill inwall, and are fixed together by a disk towards the other end at ball mill inner chamber middle part.In the actual use, because ball mill does not stop to rotate, abrasive media is constantly to do cast and decline movement, therefore friction and the impact that is subjected in the middle part of partition panel and the discharging web plate is maximum, cause the middle part wearing and tearing and the fracture easily of partition panel and discharging web plate in the actual production, cause the service life of partition panel and discharging web plate short.
Summary of the invention
The purpose of this utility model provides a kind of ball mill partition panel and discharging web plate, and this installs not only intensity height, and good impact resistance, and long service life help saving production cost.
The technical solution of the utility model is achieved in that it comprises by plurality of sections having the circular dividing plate that the sheet sheet material in grid hole is combined to form, be respectively equipped with between the linking part of described each section sheet sheet material and inner wall of ball mill drum and be the connector that turns shape, one end of described connector is connected with inner wall of rotary drum, and bolt hole and the nut of the other end on the connecting portion of bolt penetration hole and connecting bolt and sheet sheet material realized being connected.
The utility model has the advantages that design is unique, rational in infrastructure, intensity height not only, good impact resistance, and long service life help saving production cost, and have bigger promotional value, and its market prospects are considerable.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further elaborated.
As shown in drawings, this ball mill partition panel and discharging web plate 100 comprise by plurality of sections having the circular dividing plate 120 that the sheet sheet material 121 in grid hole 122 is combined to form, be respectively equipped with between the linking part of described each section sheet sheet material and balling drum 200 inwalls and be the connector 110 that turns shape, one end of described connector is connected with inner wall of rotary drum, and bolt hole 124 and the nut 127 of the other end on the connecting portion of bolt penetration hole and connecting bolt 111 and sheet sheet material realized being connected.
The connecting portion of above-mentioned sheet sheet material is provided with the nut deep gouge, and described nut is located in the nut deep gouge, and the perimembranous of described nut deep gouge is provided with the protection ring body 123 of projection, is beneficial to protect nut and connecting bolt not to be subjected to the impact of the steel ball in the ball mill.
Above-mentioned connector is provided with the protruding block set 112 that is set in circular dividing plate periphery; described protruding block set its periphery wall on the section in the center of circle of crossing circular dividing plate is tapered; be beneficial to protect the peripheral part of circular dividing plate not to be subjected to the impact of the steel ball in the ball mill; can play simultaneously the effect of fixing circular dividing plate, with prevent circular dividing plate when cylinder rotates at a high speed because of come off by centrifugal action.
Above-mentioned bolt is the first cubic dormant bolt.
Above-mentioned connector is connected with inner wall of rotary drum with nut 113 outside being located at cylinder through the second cubic dormant bolt 114.
The grid hole that above-mentioned sheet sheet material is provided with is the distributed in grid of alternating expression, and described grid is made of some net bars 125 that are horizontally arranged at interval and the perpendicular connection net bar 126 formed spaces of being located between the two adjacent net bars.
The utility model design is unique, and is rational in infrastructure, intensity height not only, and good impact resistance, and long service life help saving production cost, and have bigger promotional value, and its market prospects are considerable.
