Preprocessing device of lithium ion battery electrode active material

The utility model provides a preprocessing device of lithium ion battery electrode active material, including the cylinder, the both ends of cylinder are provided with inlet pipe and discharging piperespectively, set up the interior spiral shell area of a plurality of spirals on the inner wall of cylinder, and the height in interior spiral shell area is 110~13 of cylinder internal diameter, distance in adjacent between the spiral shell area is 100~300mm, has placed the compression roller between the interior spiral shell area. The utility model provides a device, spiral shell area, compression roller combination carrying on material processing in adopting can also carry out micro grinding to the material when mixing the material when the barrel is rotatory for the material granule is level and smooth, and then improves the bulk density of material. Have a plurality of mixing section among this preprocessing device, can be effectual carry out intensive mixing to the material, guaranteed the quality of product
