AI Technical Summary

Technical Problem

In multi-rotor air jet mills, the airflow interference between multiple rotors in the same classification area affects classification efficiency and accuracy.

Method used

The grading chamber is divided into independent chambers by a partition, and adjacent grading rotor assemblies are separated by the partition. The grading chamber and the crushing chamber are detachably connected by a flange assembly. The structure is reasonable and avoids mutual interference between the rotors.

Benefits of technology

It improves crushing efficiency and precision, thereby enhancing product quality.

Abstract

A multi-rotor jet mill relates to the technical field of crushing structures and comprises a grading cavity and a crushing cavity which are arranged side by side from top to bottom, a plurality of grading rotor components are arranged in the grading cavity in a surrounding manner, adjacent grading rotor components are separated through partition plates, and the area where each grading rotor component is located is divided into independent grading cavities through the partition plates. The multi-rotor airflow mill solves the problem that in the prior art, as a plurality of rotors are located in the same classification area, airflow interference is generated, and the classification efficiency and precision are affected due to the fact that a plurality of rotors are located in the same classification area when a multi-rotor airflow mill is used.
