Description

TECHNICAL FIELD

[0002] The pyrotechnic composition is mainly composed of oxidizing agent, reducing agent and binding agent, and is a mechanical mixture of multiple components. In the production of the pyrotechnic composition, appearance is listed as one of the inspection items. Through appearance inspection, the fineness and mixing uniformity of each component of the composition can be observed. In order to obtain the required particle size (fineness), the crushed raw materials need to be selected by sample screening, and the materials on the screen, the materials between the screens and the materials under the screen are screened, and the consistency of the particle size of the materials between the screens is the best. The existing pyrotechnic composition granulation method mainly consists of crushing and screening processes. Since the pyrotechnic composition has high sensitivity and large safety risk, the crushing method has been using the rolling and extrusion operation mode in the production of the pyrotechnic composition for a long time.

Manual material collection has the safety hazards of friction and static electricity spark.

[0005] (2) Grinding granulation. The grinding granulation method uses a wheel mill (grinding) to cooperate with a granulation device for screening. The wheel mill is used to crush the material, and the crushed material is taken out and then granulated and screened by the screening device. At present, the wheel mill feeding and taking operation is manually operated, and there are safety hazards of friction and static electricity spark, and the operator needs to strictly perform the safety operation procedures to ensure the safety and reliability of the operation process.

[0006] Therefore, it is urgent to explore a suitable technical means to improve the safety of the operation, improve the product quality and simplify the operation process, so as to ensure the consistency of the quality of the produced composition and achieve the purpose of low risk and high efficiency.
