Description

Technical Field

[0001] The utility model relates to the technical field of air classification, in particular to an air classifier for bentonite. Background Art

[0002] Bentonite is a clay mineral with strong water absorption. It is mainly composed of montmorillonite, which has a layered structure. Each layer is composed of two layers of silicon-oxygen tetrahedrons sandwiching a layer of aluminum-oxygen octahedrons. This structure forms tiny spaces between the layers, which can adsorb and retain moisture.

[0003] The existing bentonite air separator can only collect qualified bentonite. The unqualified bentonite needs to be re-crushed in other instruments, and after being crushed and collected, it is put into the separator again for re-classification. Working back and forth in different instruments will lead to low working efficiency. At the same time, due to the strong water absorption of bentonite, it is necessary to carry out preliminary drying operations on it. The existing bentonite air separator lacks preliminary drying of bentonite, which will not only affect its sorting efficiency but also its sorting quality. Summary of the Invention
