Problems solved by technology

[0004] (1) The grinding effect between each layer is poor: because only the grinding spheres near the multiple radial stirring bars in each layer can produce significant movement, the grinding spheres in other areas cannot produce significant relative movement, and it cannot make the up and down The spheres between the layers produce significant relative motion, which reduces the grinding effect of adjacent spheres on the tiny particles between the two spheres, and the grinding efficiency is low
[0005] (2) The grinding effect of the center of the ball mill bucket is poor, and the uniformity of grinding and refinement is poor: because the stirring spindle drives the radial stirring teeth to rotate around the center of the spindle, obviously, the farther away from the centerline of the stirring spindle, the greater the linear velocity, that is The closer to the circular area with the larger radius of the ball mill barrel, the greater the grinding effect of the ball on the material
On the contrary, in the small-radius cylinder near the center of the ball mill bucket, because the linear velocity of the radial stirring bar is low, the relative movement speed of the steel balls in this part is low
The grinding effect near the center of the ball mill barrel is worse than that at the outer ring

Abstract

An inner-outer-layered ball-milling device with forced axial flow and up-down circulation includes a ball-milling cup in a composite multilayer barrel type. The ball-milling cup is connected to a swing arm. The swing arm is connected to a vertical column. The bottom of the vertical column is connected to a pedestal. An upper cross beam is connected to the upper part of the vertical column. An output shaft of a servo motor is connected to a stirring shaft of the ball-milling cup through a reducer. The pedestal, the vertical column and the upper cross beam are connected to each other to form a C-shaped device body of which three surfaces are opened. The ball-milling cup is in a three-layer barrel structure so that not only can a circumferential forced movement be formed between steel balls and micro particles, but also a circulating turning movement is formed due to the effect of the stirring shaft in the axial direction. The inner-outer-layered ball-milling device is greatly increased in ball-milling efficiency.

Description

technical field [0001] The invention belongs to the technical field of ball milling devices, and in particular relates to a ball milling device with inner and outer layers forced to flow axially and circulate up and down. Background technique [0002] When the mechanical powerful ball milling method is used to prepare micro-nano powder in the laboratory, the power source drives the mechanical spindle to rotate to make the spheres for stirring and grinding mechanically move, so that collisions and relative frictional motions occur between the spheres for grinding, so that the tiny particles are crushed. Grind finely. At present, mechanical ball milling technology is becoming one of the main preparation technologies for various metastable phases, non-equilibrium phases, supersolid solution alloys, micro-nano powders, etc. that are difficult or impossible to obtain by traditional methods. [0003] The traditional ball mill only acts on the steel balls by exerting force and mov...
