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. (2) Background technology: [0002] In the chemical material industry, the use of chemical synthesis and non-metallic ores powders is becoming more and more widely used. The non-metal powders can reach the fineness of 800 mesh to 1250 meshes after being processed by advanced pulverizers. Due to the interaction of static electricity generated in the crushing process The effect causes the powder particles to produce gravitational action and are adsorbed together, which is difficult to separate. It is difficult to agitate and disperse in the paint and cause the phenomenon of sinking. In plastic materials, powder agglomerates will form a large number of void defects, which will lower the mechanical properties of the material. The solution to this problem is to coat a layer of active agent or coupling agent with a molecular thickness on the ...
