Scraper for planetary ball mill

Abstract

The invention provides a scraper for a planetary ball mill. The scraper comprises a body, wherein the body is provided with a frame structure; and the body is built in a ball milling tank and is close to an inner wall of the ball milling tank. The scraper disclosed by the invention is applied to various planetary ball mills, the special scraper is arranged in the used ball milling tank, and the international problem that materials are agglomerated at the tank bottom and on the tank wall of the ball milling tank in the ball milling process of the ball mill is solved, so that the materials are always dispersed in the ball milling tank, milling balls and the materials can be fully collided and milled in the ball milling tank, and the ball milling effect is greatly improved.

Description

technical field

[0001] The invention relates to a ball mill, in particular to a wall scraper for a planetary ball mill. Background technique

[0002] The working principle of various traditional planetary ball mills is to put the grinding balls and materials into the ball mill pot, and the ball mill pot is installed on the ball mill, and it performs high-speed planetary motion through the motor and transmission mechanism. As a result of planetary motion, the trajectory of materials and balls in the ball mill is chaotic. The materials and balls, and between the materials and the wall of the ball mill collide and grind each other at high speed, making the particle size of the materials finer and finer. However, in practice, it is found that after the materials in many ball milling tanks are ground to a certain fineness, they will stick to the bottom and wall of the ball milling tank and form lumps, and the lumps will get bigger and bigger, making the balls and balls into lumps...

Examples

Embodiment Construction

[0017] See figure 1 and figure 2 As shown, a wall scraper for a planetary ball mill has a body 1; the body 1 has a frame structure, and the body 1 is built into the ball mill pot 2 and is close to the inner wall of the ball mill pot 2. The body 1 is arranged crosswise by at least two square frames 3 with the same structure. The body 1 has two square frames. The length and width of the square frame 3 are close to the inner diameter and inner height of the ball mill jar 2 . Reinforcing ribs can be added in the middle of the square frame 3 . The frame edge of the square frame 3 is in the shape of plane, triangle or zigzag.

[0018] Its working process is as follows: first put the device, materials and balls into the ball mill pot 2, and see the status of the device put into the ball mill pot 2 figure 1 , cover the ball milling pot 2, and place the whole ball milling pot on the ball mill. When the ball mill is working, the ball milling pot rotates at a high speed, and the ba...
