A plurality of inclined stripes inclined towards the discharge port are formed on the surface of the lining plate in the axial direction of the barrel. Magnetic steel balls are arranged in the barrel. By means of the content, the ball mill has the beneficial effects that the structure is simple, and grinding materials are fully ground in the barrel while moving at a constant speed, and compared with an existing ball mill, the grinding efficiency is greatly improved.
Description
Technical field
The present invention relates to ceramic machinery field, particularly relate to the efficient ball mill of a kind of uniform grinding.
Background technology
Ball mill is a kind of breeze grinding machinery common in Production of Ceramics.In ball mill, topmost workpiece is liner plate and milling medium, milling medium and Ore are to the impact of inner liner of bowl mill and abrasion, ball grinding machine lining board is made to become one of the main consumable material in ball mill operating, therefore, the quality of liner plate quality and performance directly influences the service life of ore grinding quality and ball mill.
After abrasive in ball mill barrel grinds fully, it is necessary to be transported to discharging opening and get rid of, it is ground adding new abrasive；Prior art adopts and is provided with screw structure in inner barrel, utilize helical gradient to be transported by abrasive, or be provided with angle regulator at cylinder body bottom so that described discharging opening is lower than described charging aperture, thus being moved near discharging opening by abrasive；But former structure is complicated and be not suitable for the irregular cylinder of liner plate in above-mentioned two scheme, relation between inclination angle and the translational speed of abrasive of the latter is uncertain, different materials is different in the position translational speed that cylinder is different, so that abrasive grinds uneven, insufficient.
Summary of the invention
But it is an object of the invention to propose a kind of abrasive at the uniform velocity moving process and the efficient ball mill being uniformly fully ground.
For reaching this purpose, the present invention by the following technical solutions:
A kind of efficient ball mill of uniform grinding, including the cylinder being provided with charging aperture and discharging opening, it is located at the liner plate of inner barrel and is located at the driving device of described cylinder body bottom, described driving device drives described barrel body rotation, described liner plate is filled block by alumina lining brick and forms, described backing surface along described cylinder be axially formed some to discharging opening tilt slanted bar stricture of vaginas, described cylinder is built with magnetic steel ball.
Described inner barrel is provided with liner plate and magnetic steel ball, described liner plate is protecting outside described tube structure, with the grinding efficiency that described magnetic steel ball together improves described ball mill, slanted bar stricture of vagina on described liner plate tilts to described discharging opening, concaveconvex structure on liner plate makes the grinding function of described liner plate strengthen on the one hand, on the one hand described slanted bar stricture of vagina along with described cylinder rotate time, worked by the direction of rotation one of its gradient advantage and cylinder, the abrasive in cylinder is made to be transported to discharging opening gradually, make need not installing helical structure structure and just at the uniform velocity abrasive being transported described cylinder of described inner barrel, ensure that structure is simpler while cylinder is to abrasive conveying effect, maintenance and installation is more convenient.
Further illustrating, described cylinder 1 is made for ferrum, and the gravity of described magnetic steel ball is more than the active force between described cylinder and described magnetic steel ball.
Described magnetic steel ball to play the effect of the grinding efficiency improving described ball mill, it is necessary that have certain captivation between described magnetic steel ball and described cylinder, and this captivation again can not be excessive, ensure described magnetic steel ball under self gravitation and self captivation effect with described cylinder can with described cylinder time and press close to, time and separate, and so arrange, also avoid the magnetic steel ball excess impact to liner plate, extend the service life of described ball mill.
Further illustrating, the gravity of described magnetic steel ball is more than the active force between described magnetic steel ball.
In described cylinder, be placed with plural described magnetic steel ball, described magnetic steel ball will be made to give full play to abrasive action, it is necessary to the time of attraction time between described magnetic steel ball under self gravitation and captivation effect each other and separate.
Illustrating further, described slanted bar stricture of vagina substantially equidistantly mode is formed on the surface of described inner lining structure.
Slanted bar stricture of vagina described in spaced set, effect after can making on the one hand the abrasive grinding rate of diverse location in described cylinder and grinding is essentially identical, on the other hand abrasive can be moved by the discharging opening to described cylinder at the uniform velocity in described cylinder, it is ensured that the grinding of described abrasive is enough abundant.
Being transition circle cambered surface between described adjacent two slanted bar stricture of vaginas, described arc surface radius is 2-5cm, and bigger than the radius of magnetic steel ball.
If the magnetic steel radius of a ball described in described arc surface radius ratio is little, described magnetic steel ball then can not enter described arc surface and be ground so that the degree of grinding of abrasive is uneven；If the magnetic steel radius of a ball described in described arc surface radius ratio is equal, described magnetic steel ball easily blocks so that the abrasive in described cylinder grinds and discharging process all can not be smoothed out；If the magnetic steel radius of a ball described in described arc surface radius ratio is much larger, the abrasive in described arc surface can be made again to increase, so that described abrasive moves too fast at described cylinder, cause grinding insufficient；Therefore only when described arc surface radius is 2-5cm, and time bigger than the radius of magnetic steel ball, the abrasive effect grinding discharging next is better.
More excellent, described alumina lining brick removes the described generally rectangular structure of oblique stripe portion.
The alumina lining brick of substantially rectangular in cross section structure, combined and instant in described cylinder, the size of combinational gap can be readily obtained control by the extruding of single direction.
More excellent, a side elevation of described alumina lining brick is respectively equipped with tongue-and-groove, the opposite side facade that described alumina lining brick is relative with a described side elevation is provided with the tenon platform closed with described tongue-and-groove tenon.
Described alumina lining brick arranges described tongue-and-groove and tenon platform, facilitate the integrated positioning between described alumina lining brick, make described liner plate easy to installation and maintenance while reduce the combinational gap between described alumina lining brick, the structure making described ball mill is more stable, longer service life.
