AI Technical Summary

Problems solved by technology

The main problems are as follows: 1. High energy consumption and low production efficiency
2. The output is less, generally no more than 100kg / h, most of which are less than 50kg / h
3. It is still difficult to prepare superfine powder
4. The structure of jet mill is complex and expensive
[0006] Ultrafine powder (submicron and nanoscale) is the basic material in the 21st century and one of the hot spots of international competition in the current high-tech field; currently there are technical literature reports that it can be produced by chemical methods, but the ultrafine powder produced by chemical methods Powders often change the physical properties of the material itself, and cannot achieve the use effect of ultrafine materials. The problem of agglomeration is difficult to solve, and the production efficiency is low and the price is expensive.
