Abstract

The present invention discloses a powder modification and fluidization system, including a feeding system, a smashing and dispersing system which communicates with the feeding system, a powder transmission system which communicates with the crushing and dispersing system, and a powder collecting system which communicates with the powder transmission system. The powder transmission system includes a transmission pipe and a wind power device, which makes the powder directionally run along the transmission pipe. The powder modification and fluidization system also includes a powder activating and modifying agent adding system, which includes a atomizing device which is arranged on a powder running loop to spray a atomizing, activating and modifying agent. When the present invention is working, a thick powder is smashed and dispersed, at the same time the atomizing, activating and modifying agent which is sprayed by the atomizing device packs the powder to eliminate the static electricity on the surface of individual powder, so as to achieve the purpose of activating and modifying the powder. The present invention can smash and disperse the powers of a micron grade and a submicron grade completely and efficiently. A quite thick powder is used as the raw material to obtain the activated powders with different granular size.

Description

(1) Technical field: [0001] The invention relates to a powder modification equipment, in particular to a powder modification fluidization system. (two) background technology: [0002] In the chemical material industry, powders such as chemical synthesis and non-metallic ores are increasingly used. Non-metallic powders can reach a fineness of 800 mesh to 1250 mesh after being processed by advanced pulverizers. Due to the interaction of static electricity generated during the pulverization process The effect causes the gravitational effect between the powder particles and they are adsorbed together, making it difficult to separate, and the powder clusters that aggregate into a powder group several times the size of the primary powder particles are difficult to stir and disperse in the coating, resulting in bottom sinking. In plastic materials, powder clusters will form a large number of void defects, which will reduce the mechanical properties of the material. The solution to ...
