Abstract
The utility model relates to a permanent magnetic ferrite presintering material's production facility especially relates to a grinding device, more specifically says so and relates to an equipment that is used for sour regeneration iron red to grind. To the problem that the material glues the wall and blocks up ejection of compact castor board among the sour regeneration iron red grinding process, the utility model discloses a continuous ball mill for sour regeneration iron red grinds, including barrel, feed inlet, discharge gate, laminating and the welt of barrel inner wall and set up in the vibration castor board of discharge gate, the vibration castor board includes vibrating motor, ejection of compact stock guide, damping spring and the castor body, on the castor body is fixed in ejection of compact stock guide, the welt is for having the rubber welt of boss, the castor body is network structure. The continuous tube ball mill can continuously run for 24 hours, and the machine hour efficiency of the equipment is far higher than that of a compacting machine with the same specification.
Description
Technical field
The present invention relates to a kind of production equipment of permanent ferrite prefiring material, particularly relate to a kind of milling apparatus, relate to a kind of equipment that the acid regeneration iron oxide red grinds that is used for more specifically.
Background technology
The grinding and the batch mixing of the acid regeneration iron oxide red in the existing permanent-magnet ferrite production process mainly contain three kinds of modes, and first kind is to adopt closed ball mill to add the water wet grinding, but higher because of the slip moisture content, energy consumption is more than 3 times of dry method in pre-burning material production process; Second method is to adopt vibrating ball to grind; The grinding effect of this mode is better; But there is the problem that production capacity is low, dust is big, noise is big and equipment failure rate is high; The third mode is to select for use pre-pressing machine to grind, but the efficient of this mode of production is lower, has only 50% equipment hour efficiency of same specification tube mill.So we strive to find a kind of mode always, can the production of acid regeneration iron oxide red be placed on the continuous tube mill and accomplish, but because the acid regeneration iron oxide red is spongelike structure, mobile relatively poor, bulk density only there is 0.35t/m
3, when its ratio was higher than 30%, very easily weldbonding caused ball mill discharge grate plate to stop up on cylinder inboard wall or slotted eye under gravity impacts, so do not solve this difficult problem, just can't adopt continuous ball mill that the acid regeneration iron oxide red is ground or batch mixing.
Summary of the invention
Problem to sticking wall of material in the acid regeneration iron oxide red process of lapping and obstruction discharging grate plate; The utility model discloses a kind of continuous ball mill that the acid regeneration iron oxide red grinds that is used for; Comprise cylindrical shell, charging aperture, discharging opening; Fit and the liner plate of cylinder inboard wall and the vibration grate plate that is arranged at discharging opening, said vibration grate plate involving vibrations motor, discharging stock guide, damping spring and castor body, said castor body is fixed on the discharging stock guide; Said liner plate is the rubber lining that has boss, and said castor body is a network structure.Because traditional irony liner plate is replaced with the rubber lining that has boss; So steel ball and material can be by boss along with the rotation of the ball mill certain altitudes that rises; When steel ball when eminence falls; Impact rubber lining, shaking falls to being bonded in the material on the liner plate, reaches the purpose of cleaning liner plate sizing.Simultaneously, to the problem of discharging opening easy blocking, the castor body of the utility model discharging opening is set to network structure; Thereby when solving discharging slotted eye smoothness; Make the discharging grate plate that certain elasticity arranged, under the steel ball extruding, produce vibration, prevent that material is bonded with discharging and results in blockage on the net.Certainly, because the castor body itself plays the effect of sieves, so this cancellated mesh need be according to the size of steel ball, and the requirement that material itself is ground decides, and its mesh only allows to meet the material whereabouts of product fineness.
The present invention serves as to investigate point with boss to the power of rising of ball mill, obtains through a large amount of experiments, and the optimum height of boss is 50mm.
As further improvement; The inventor has also carried out further research to the set-up mode of boss; And disclose said boss in this application and be equally distributed in rubber lining, when the distance between the particularly said boss was 200mm～400mm, boss was to the Li Genggao that rises of ball mill.
Another kind as the utility model improves, and also is provided with soft rubber liner and rapping steel ball on the said discharging stock guide, drops out the buildup on the material stock guide thereby in the ball mill running, shake, and prevents that further material is bonded on the discharging stock guide.
To sum up, adopt the disclosed dry grinding 100% acid regeneration iron oxide red of the utility model, can realize running without interruption continuously of continuous tube mill 24 hours, and the equipment equipment hour efficiency is far above the pre-pressing machine of same specification.

Fig. 1 is the continuous ball mill sectional view;
Wherein 1-cylindrical shell, 2-charging aperture, 3-discharging opening, 4-rubber lining, 5-boss, 6-castor body, 7-discharging stock guide, 8-soft rubber liner, 9-steel ball, 10-raw material.
The specific embodiment
Embodiment 1
As shown in Figure 1, continuous ball mill includes cylindrical shell 1, charging aperture 2, discharging opening 3, on the inwall of cylindrical shell 1, also is fitted with rubber lining 4, and said rubber lining 4 is provided with boss 5, and boss 5 equidistantly is distributed in the cylindrical shell 1.The grate plate of discharging opening 3 comprises discharging stock guide 7, with and the soft rubber liner 8 that go up to be provided with, on soft rubber liner 8, also be provided with and be cancellated castor body 6.
During grinding, steel ball 9 and raw material 10 by boss 5 along with the rotation of the ball mill certain altitude that rises, when steel ball 9 when eminence falls, impact rubber lining 4, shaking falls to being bonded in the material on the rubber lining 4, reaches the purpose of cleaning liner plate sizing.Simultaneously, when material process discharging opening 3,,, under steel ball 9 extruding, produce vibration, prevent that material is bonded with discharging and results in blockage on the net so itself had certain elasticity because castor body 6 is a network structure; Simultaneously, because the effect of electric motor of shaker, the steel ball 9 that is arranged at discharging opening 3 places is upspring, and impact soft rubber liner 8 during the whereabouts, thereby buildup on the stock guide that in the ball mill running, shakes prevents that material is bonded on the stock guide.
In December, 2010; Carry out commerical test at 1,500 5700 continuous ball mills, employing should technology after, accumulative total is moved nearly 30 hours; Do not occur the situation that obvious sizing stops up on inspection on cylinder inboard wall, discharging screen cloth and the discharging stock guide, can realize running without interruption continuously of continuous ball mill 24 hours; And the equipment unit-hour output can reach 2t/h, and equipment hour efficiency is more than 2 times of pre-pressing machine dry grinding acid regeneration iron oxide red of same specification.
