Crushing and shaping integrated production line

Abstract

The invention discloses a crushing and shaping integrated production line and relates to the technical field of powder equipment. The crushing and shaping integrated production line comprises a crushing and shaping integrated machine; a crushing and shaping device and a grading device are mounted in a cylinder body of the crushing and shaping integrated machine; the crushing and shaping device comprises a wind wheel, a crushing disc and a shaping hammerhead which is fixedly arranged on the inner wall, corresponding to the crushing disc, of the cylinder body; the grading device comprises an impeller; a material inlet is formed in the cylinder body between the crushing disc and the impeller; a fine powder outlet is formed in the cylinder body between the impeller and a second power device; a coarse powder material outlet is formed in a position, corresponding to the crushing disc, on the cylinder body. The crushing and shaping integrated production line disclosed by the invention has the advantages that crushing, shaping and grading functions are simultaneously achieved; the whole crushing and shaking process is carried out in one closed equipment so that material overturning is avoided and material pollution caused by mixing other materials in the material in the overturning process is completely eliminated; product quality is improved; the crushing efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of powder equipment, in particular to an integrated crushing and shaping production line. Background technique [0002] Scientific research has proved that the particle size and uniformity of particle size distribution of lithium-ion battery negative electrode materials greatly affect the real density and specific surface area of ​​the material, which in turn has a great impact on the first charge and discharge capacity and first cycle efficiency of the negative electrode material. . It is reported in the literature that when the average particle size of the negative electrode material is 16-18 μm, and the particle size distribution is relatively concentrated, the lithium-ion battery has better first-time charge-discharge capacity and first-time cycle efficiency. Through the crushing of the negative electrode material, the negative electrode material with the required size can be obtained. Through the surfa...

Problems solved by technology

[0003] The traditional anode material production line uses one or several sets of equipment for the crushing and shaping links to crush and shape the materials respectively. During the inversion process, the materials are likely to cause material defects, generate a large amount of dust and pollute the environment. At the same time, the materials are in the inversion process It is easy to cause other substances to be mixed in, which will pollute the material itself, and then affect the product quality. The whole production process requires more manpower and equipment consumes more energy.
