Description

Technical Field

[0001] The utility model belongs to the technical field of mixing equipment, and in particular relates to a precipitation slurry shearing device. Background Art

[0002] At the moment of precipitation slurry generation, the particles are in the initial formation stage, the structure is relatively loose and not completely solidified. At this time, shearing with a shearing device can obtain particles with more uniform size distribution. If the precipitation slurry is waited for to form solid particles before shearing, it is difficult to shear the solid particles evenly during the shearing process due to the relatively tight internal structure of the solid particles, which may easily lead to problems such as uneven solid particle size and some solid particles being too large or too small.

[0003] When shearing solid particles, in order to enhance the shearing effect and control the shape of solid particles, grinding media are usually required, which will cause the wear particles of the grinding media to mix into the product, introduce impurities, and affect the purity and performance of the product. At the same time, as the use time increases, the grinding media will gradually wear out, thus affecting the shearing effect. When the performance of the grinding media drops to a certain level, it is necessary to stop the machine to replace or add new grinding media, which will cause the production process to be interrupted and reduce production efficiency.
