Planetary ball mill

Abstract

The invention provides a planetary ball mill, and particularly relates to the technical field of smashing equipment. The planetary ball mill comprises a ball mill body, a rotary disc is arranged on the ball mill body, and a plurality of ball milling pots are arranged on the rotary disc. Each ball milling pot comprises a pot base and a pot body, wherein the pot base comprises a pot base bottom plate arranged on the rotary disc, the pot base bottom plate is of a circular ring structure with an opening formed in the top surface, pot side plates are oppositely arranged on the opening in the top surface of the pot base bottom plate, each pot side plate is of an arc plate structure, one end of each pot side plate is fixedly arranged on the opening in the top surface of the pot base bottom plate,the other end of each pot side plate is provided with a plate clamping notch, an external thread rod is vertically arranged on the pot base bottom plate, one end of the external thread rod penetratesthrough the pot base bottom plate, and a scraping rod is arranged on the side wall of one end of the external thread rod. The planetary ball mill has the advantages that the situation that the grinding effect is reduced as specimens accumulate at the bottom of the pot body can be prevented, and in the specimen scraping process, pressure between scrapers and the inner wall of the pot body can be automatically adjusted, so that damage to the inner wall of the pot body is reduced.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a planetary ball mill. Background technique [0002] The planetary ball mill is designed for crushing, grinding, and dispersing powders such as metals, non-metals, organics, and Chinese herbal medicines. It is especially suitable for laboratory research. Produce strong shearing, impact, and rolling to achieve the purpose of crushing, grinding, dispersing, and emulsifying materials. 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 lum...

Problems solved by technology

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. The material cannot be ground, which affects the ball milling effect
