Vertical continuous stirring ball-milling equipment and working method thereof

Abstract

The invention discloses vertical continuous stirring ball-milling equipment which comprises a barrel, a plurality of grinding balls, a barrel cover, a stirrer and an air inlet and outlet control system; the barrel is vertically arranged; the plurality of grinding balls are arranged in the barrel; the barrel cover covers a top opening of the barrel in a sealing manner; the stirrer penetrates through the barrel cover, extends into the barrel and can rotate; materials placed in the barrel are ground by the grinding balls under the rotation of the stirrer; the air inlet and outlet control system comprises an air inlet channel and an air outlet; one end of the air inlet channel is arranged on the bottom surface of the barrel and communicated with the inside of the barrel, and the other end is communicated with a pressurized air tank or an air pump outside the barrel; the air outlet is formed in the barrel cover; the air inlet and outlet control system further comprises a spherical crown type cover plate, and the spherical crown type cover plate is arranged in the barrel, covers a port of the air inlet channel and is connected with the bottom face of the barrel through an elastic piece; and a feeding hole penetrating through the inside and the outside of the barrel is formed in the barrel cover. The vertical continuous stirring ball-milling equipment has the advantages of continuous processing, accurate product particle size control, high efficiency, energy saving and the like.

Description

technical field [0001] The invention belongs to the technical field of powder processing machinery and equipment, and relates to a ball mill, in particular to a vertical continuous stirring ball mill and a working method thereof. Background technique [0002] Stirring ball mill is the key equipment in the field of electronic raw materials and nano-materials production. It is also a common powder processing equipment widely used in biology, food, cosmetics, medicine, materials, mining, metallurgy and other industries. The shearing and collision between the steel ball or ceramic ball and the raw material realizes the crushing and grinding of the material. However, the existing stirring ball mill cannot produce continuously on the one hand, and on the other hand, the material processing parameters are all empirical parameters, and the particle size distribution of the product is wide, which affects the quality. The existing ball mill needs to suspend the ball mill, open the co...
