AI Technical Summary

Problems solved by technology

Obviously, the fluidity and bulk density of the short-strip modeling powder are difficult to achieve an ideal state; 3. The spray modeling powder is spheroidized and granulated
The quality of the product prepared by the spray molding powder spheroidization system is good, but the equipment is complex, consumes a lot of power, and requires a lot of space for assembly and control of the equipment
This granulation method is not optimal for the preparation of laboratory-scale small quantities of products

Description

technical field [0001] The invention relates to a preparation device for explosive molding powder, in particular to a spherical molding device for explosive molding powder, which is suitable for spherical molding of explosive molding powder. Background technique [0002] Press-fit molding is an important way of molding explosive products. Products prepared by this process have many advantages such as high molding dimensional accuracy, high molding density, and convenient molding. The raw material for press molding of explosives is called modeling powder. The morphology, particle size and bulk density of the molding powder have a very important influence on the quality of the final compacted product. Generally speaking, the molding powder with higher bulk density, spherical shape, and moderate particle size will produce a higher density product. The higher the density of the shaped grain, the higher the detonation velocity, detonation pressure, and detonation heat of the exp...
