Superfine powder grading plant

Technical Field

The utility model relates to a superfine powder grading plant. Specifically, the method is used for separating coarse particles and ultrafine particles of powder particles having a particle size of less than 5 um.

Background

The powder, especially the superfine powder, is widely applied in various industries of national economy, and the requirement on the powder is higher and higher along with the expansion of the application range of the powder. The finer the powder particles, the narrower the particle size distribution of the powder, the wider its application range, and the more excellent its performance after being applied to products.

The existing powder processing field adopts a mechanical processing method, the particle size distribution range of the powder obtained after mechanical sieving is wide, and special powder grading equipment is needed to carry out grading treatment on the processed powder. The conventional powder classification methods include a gravity classification method, an inertia classification method, a cyclone method, a forced vortex classification method, and the like. However, the ultrafine powder is very easy to agglomerate due to large specific surface area and surface energy, the traditional airflow classification and screening classification are difficult to achieve the purpose of classification, and the classification efficiency is low, the classification precision is poor, the pollution is very easy to occur, and the like. The purpose of classifying the superfine powder can be achieved to a certain extent by water flow classification, but a plurality of use limitations exist, and the classified powder is dried and easily hardened, so that the later-stage processing and use are not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an ultrafine powder classifying device which can effectively separate coarse particles and ultrafine particles of powder particles with the powder particles smaller than 5 um.

In order to achieve the purpose, the technical scheme of the utility model is as follows:
