Abstract
The utility model discloses an improved grid lining plate of a grid-type ball grinder, comprising an outer circumferential lining plate and an inner circumferential lining plate, wherein the outer circumferential lining plate is an integral annular lining plate consisting of 12 sector grid plates, the inner circumferential lining plate is an integral circular lining plate consisting of 12 sector grid plates, the inner circumferential lining plate is arranged in a central hole of the outer circumferential lining plate, and the diameter of an outer circle of the inner circumferential lining plate is matched with the diameter of the central hole of the outer circumferential lining plate. According to the improved grid lining plate of a grid-type ball grinder disclosed by the utility model, an original central lining plate is removed, a part of the inner circumferential lining plate is designed to directly replace the central lining plate, and the inner circumferential lining plate is fixed on an end cover of a material discharge opening through a bolt in a working process so as not to remove during operation; therefore, the inner circumferential lining plate cannot fall off during the operation so that a ball grinder is unlikely to have failure, the operation efficiency of devices is improved and the labor intensity is reduced.
Description
Technical field
The utility model relates to the grate ball mill field, relates in particular to a kind of improved grate ball mill grid liner plate.
Background technology
Grate ball mill is to utilize steel ball in ball mill barrel, to do to throw to let out motion, thereby to the bump that weares and teares of the lump in the cylindrical shell, makes lump be fragmented into graininess; The grid liner plate that covers installation through the ball mill discharge port end flows out; The structure of existing grid liner plate is as shown in Figure 1, is made up of outer ring liner plate 2, inner ring liner plate 3 and center liner plate 4, and outer ring liner plate and inner ring liner plate are formed whole annular grate by 12 fan-shaped grates; And outer ring liner plate and inner ring liner plate all are fixed on the discharging opening end cap 1 of ball mill through bolt 5; The center liner plate is made up of two blocks of semicircle liner plates, and itself does not have bolt, and periphery has ear; Ear is pressed in below the inner ring liner plate, plays fixation.In use for some time, the center liner plate is loosening easily, and steel ball and big ore particles influence the ore dressing effect by loosening local the outflow; And the wearing and tearing of the ear of loosening rear perimeter edge are very fast, and obscission often appears in the center liner plate, and its maintenance difficulty is bigger, and influences running rate.
Summary of the invention
In order to overcome the deficiency in the background technology, the purpose of the utility model has provided a kind of improved grate ball mill grid liner plate, can prolong the service life of grid liner plate, improves the running rate of equipment, reduces production costs.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of improved grate ball mill grid liner plate; It comprises outer ring liner plate and inner ring liner plate; The outer ring liner plate is formed integral ring-shaped liner plate by 12 fan-shaped grates; The inner ring liner plate is formed the unitary circular liner plate by 12 fan-shaped grates, and the inner ring liner plate is positioned at the centre bore of outer ring liner plate, and the center-hole diameter of the outside diameter of inner ring liner plate and outer ring liner plate matches.
Described improved grate ball mill grid liner plate is provided with screw on 12 fan-shaped grates of its composition outer ring liner plate.
Described improved grate ball mill grid liner plate is provided with screw on 12 fan-shaped grates of its composition inner ring liner plate.
Owing to adopt aforesaid technical scheme, the utlity model has following beneficial effect:
This improved grate ball mill grid liner plate removes original center liner plate, is designed to a direct part by the inner ring liner plate and has replaced the center liner plate; In the course of work, owing to the inner ring liner plate covers through being bolted to discharge port end, therefore; The inner ring liner plate can not come off in the running; Make that ball mill is not easy to break down, improved operation rate, reduced labour intensity.
Description of drawings
Fig. 1 is the structural representation of existing ball mill grid liner plate;
Fig. 2 is the ball mill grid liner plate sketch map of the utility model;
Among the figure: 1-discharging opening end cap; 2-outer ring liner plate; 3-inner ring liner plate; 4-center liner plate; The 5-bolt.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
As shown in Figure 2; A kind of improved grate ball mill grid liner plate; It comprises outer ring liner plate 2 and inner ring liner plate 3, and outer ring liner plate 2 is formed integral ring-shaped liner plate by 12 fan-shaped grates, and inner ring liner plate 3 is formed the unitary circular liner plate by 12 fan-shaped grates; Inner ring liner plate 3 is positioned at the centre bore of outer ring liner plate 2, and the center-hole diameter of the outside diameter of inner ring liner plate and outer ring liner plate matches.Be provided with screw on 12 fan-shaped grates of described composition outer ring liner plate; Be provided with screw on 12 fan-shaped grates of described composition inner ring liner plate.
During installation, described outer ring liner plate 2 all is fixed on the discharging opening end cap 1 of grate ball mill, therefore through bolt 5 with inner ring liner plate 3; Coming off in use can not appear in the improved grate ball mill grid liner plate of the utility model, steel ball can not occur by the loosening grate phenomenon that spues, and has guaranteed the mill running rate; Outer ring liner plate in the utility model has identical service life with the inner ring liner plate; Promptly scrap simultaneously, be convenient to unified the replacing, reduced beneficiation cost.
