The invention discloses an automatic mill steel ball screening device which comprises a ball feeding hopper, a steel ball bin, a partition plate, a double-layer screening plate, a conveying belt, a first driving device and a second driving device. One side of the steel ball bin is provided with a first opening and a second opening respectively, and the first driving device and the second driving device drive the double-layer screening plate and the partition plate to move respectively. The double-layer screening plate comprises a first screening plate located on the upper layer, a second screening plate located on the lower layer and a side wall for connecting the side face of first screening plate and the side face of the second screening plate, first through holes are formed in the first screening plate, second through holes are formed in the second screening plate, closed areas among the second through holes are arranged under the first through holes, the bore diameter of the first through holes is 1-1.1 times larger than the diameter of a standard steel ball, the bore diameter of the second through holes is smaller than the diameter of the standard steel ball, the interval of the first screening plate and the second screening plate is 1-1.1 times larger than the diameter of the standard steel ball, and the height of the first opening and the height of the second openings are equal to the thickness of the double-layer screening plate and the thickness of the partition plate respectively.
Description
technical field [0001] The invention relates to the technical field of steel ball machinery, in particular to an automatic screening device for steel balls in a mill. Background technique [0002] Ball mill is one of the high-fine grinding machines widely used in industrial production. The steel ball of the ball mill is the grinding material medium of the ball mill equipment. The grinding effect is produced through the collision and friction between the steel balls of the ball mill and between the steel ball and the material. It is an important basic component, especially the precision industrial steel ball plays an important role in the development of the national economy. has a huge effect. Steel balls need to be screened and classified according to different radii before use, so that they are suitable for different places of use. In the prior art, the screening of steel balls is mainly done manually by using screens of different specifications, step by step screening fr...
