Abstract
The invention discloses a steel ball grinding mill which comprises a ball grinding mill main body 1 and a center shaft 2, wherein the ball grinding mill main body 1 is in a cylinder shape; a cavity is arranged in the ball grinding mill main body 1; the center shaft 2 is arranged in the center of the ball grinding mill main body 1; the ball grinding mill main body 1 rotates by taking the center shaft 2 as an axis; the inner surface of the cavity of the ball grinding mill main body 1 is provided with ball shoveling plates 4; the cavity of the ball grinding mill main body 1 is internally provided with a plurality of steel balls 5. The steel ball grinding mill has the beneficial effects of being provided with the ball shoveling plates, so that the crushing degree and the grinding degree of coal raw ore can be effectively improved; furthermore, a plurality of ball grinding mill main bodies can be connected with one another by flange interfaces, so that the coal raw ore can be crushed for a plurality of times, the crushing efficiency is improved, and a relatively good crushing effect can be achieved.
Description
Technical field
The present invention relates to a kind of steel ball mill.
Background technology
Steel ball mill is coal pulverizer again, is with coal crusher and wears into the machinery of coal dust, and it is the important auxiliary equipment of coal-powder boiler.The raw ore of coal is not of uniform size, the quality difference, and the utilization of can't well burning all needs it is ground into broken powder usually.Traditional ball mill just simply utilizes the gravity of steel ball to pulverize and grind, and efficient is low, and repeated workload is big.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned defective of the prior art, and a kind of steel ball mill that can adjust and grind according to different collieries hardness and degree of grinding is provided.
To achieve these goals, technical scheme provided by the invention is: a kind of steel ball mill, described steel ball mill includes ball mill main body 1 and central shaft 2, described ball mill main body 1 is cylindrical, ball mill main body 1 inside is cavity, described central shaft 2 is arranged at the center of ball mill main body 1, described ball mill main body 1 is for serve as spool to be rotated with central shaft 2, the cavity inner surface of described ball mill main body 1 is provided with sliding tackle plate 4, is provided with some steel balls 5 in the cavity of described ball mill main body 1.
Further, above-mentioned a kind of steel ball mill, the two ends of described central shaft 2 are provided with flange-interface 3, and the flange-interface 3 by central shaft 2 between the described ball mill main body 1 connects.
Further, above-mentioned a kind of steel ball mill, described sliding tackle plate 4 is perpendicular to the tangential direction setting of ball mill main body 1 cavity inner surface.
Further, above-mentioned a kind of steel ball mill, described sliding tackle plate 4 is relatively set with 4 respectively in twos.
Operation principle of the present invention is, the main body of steel ball mill can be rotated for axle by central shaft, behind loading coal raw ore and steel ball in the ball mill body cavity, the ball mill main body begins to rotate, and in the rotation process, sliding tackle plate scoops up steel ball and coal raw ore, turn to certain angle, coal raw ore and steel ball fall under the gravity effect, bump and rub, thereby reach the pulverizing of coal raw ore and grind effect.Simultaneously, can connect by flange-interface between a plurality of ball mill main bodys, after the connection, can import coal raw ore and steel ball into another ball mill main body by central shaft and carry out secondary and grind, vary in size between the ball mill main body, the abundant pulverizing that can guarantee the coal raw ore with grind.
Beneficial effect of the present invention is: a kind of steel ball mill provided by the invention, owing to be provided with sliding tackle plate, can effectively promote the degree of grinding of coal raw ore and grind degree, simultaneously, can connect by flange-interface between a plurality of ball mill main bodys, the coal raw ore is repeatedly pulverized, improved crush efficiency, can reach better crushing effect.

The specific embodiment
Embodiment 1:
A kind of steel ball mill, steel ball mill includes ball mill main body 1 and central shaft 2, ball mill main body 1 is cylindrical, ball mill main body 1 inside is cavity, central shaft 2 is arranged at the center of ball mill main body 1, ball mill main body 1 is for serving as that axle is rotated with central shaft 2, and the cavity inner surface of ball mill main body 1 is provided with sliding tackle plate 4, is provided with some steel balls 5 in the cavity of ball mill main body 1; The two ends of central shaft 2 are provided with flange-interface 3, and the flange-interface 3 by central shaft 2 between a plurality of ball mill main bodys 1 connects; Sliding tackle plate 4 is perpendicular to the tangential direction setting of ball mill main body 1 cavity inner surface; Sliding tackle plate 4 is relatively set with 4 respectively in twos.
It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment the present invention is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
