Description

Technical Field

[0001] The utility model relates to the technical field of powder flow cooling devices, in particular to a powder flow cooling device used for powder spheroidization. Background Art

[0002] Powder spheroidization is a process for making fine powder particles into spherical particles. This method is usually used to prepare granular raw materials or products to improve fluidity, reduce dust, improve packaging and transportation performance, and in some processes it is beneficial to improve reaction efficiency and product quality. Powder fluid refers to the flow behavior and performance of powder under the action of external force. The powder fluid properties have an important influence on the fluidity, compactibility and dispersibility of powder in the processes of mixing, conveying, filling, pressing and molding. In industrial production, it is often necessary to measure and evaluate the fluid properties of powder.

The utility model can safely, simply, quickly and effectively cool and passivate active materials without destroying the spheroidization effect of the powder material.

[0004] In the spheroidization process, a binder is usually required to bond the powder particles into spherical particles. If the spheroidization process is carried out at a high temperature, the binder may solidify in a shorter time and the solidification is incomplete, and a powder flow cooling device is required.

When the powder flow gathers too much, a long waiting time is required to enter the cooling of the next batch of powder flow, and the efficiency is relatively low. Therefore, a powder flow cooling device for powder spheroidization is proposed. Utility Model Content
