A pelletizer is a forming machine that can make materials into specific shapes. The device is widely applied to continuous, uniform and quantitative feeding and batching in gold selecting factories, coal mining factories, chemical engineering, capital construction, mechanized casting shops and the like. Current granulators can be mainly classified into three categories: rolling type pelletizer, extrusion type pelletizer and horizontal centrifugal high-efficiency pelletizer.

The rolling type granulator is selective to materials, requires the content of coarse fibers in a certain range, has high moisture content, can be bagged, stored and transported after being dried in the later period, and has small particle density and high bagging breakage rate.

Extrusion type granulator is a granulator which is convenient for people to store, transport and apply and is used for reference by combining the working principle of a feed granulator. The granulator of this type produces more uniform granules, high density, low moisture content, low bagging breakage rate, simple drying in the later period, and has no strict requirement on the crude fiber content of the raw materials. The disadvantages are high power consumption, certain technical requirements for operation and use and low moisture content of raw materials.

The horizontal centrifugal efficient granulator is granulator equipment which is improved by additionally arranging a paddle type rotor on the basis of a rolling granulator, keeping a roller still and rotating the rotor.

Due to the characteristics of dangerousness and the like of special pyrotechnic compositions for military products, the current granulator equipment cannot be used for military product production, only some simple wood devices or manual granulation can be adopted for more than thirty years, the working efficiency is low, manual operation is very dangerous, man-machine isolation operation cannot be realized, and great dangerousness exists.
