In the field of powder processing, some raw materials are flammable. Conventional grinding equipment lacks integrated safety protection structures; static electricity tends to accumulate during material grinding, and dusty conditions raise operational risks in workshops. Ordinary mechanical grinding relies on component impact for size reduction and generates significant heat, making it unsuitable for processing heat-sensitive and oxidizable materials. The intelligent explosion-proof model of disc jet mill works on the principle of gas collision pulverization. Equipped with an explosion-proof control system, the complete unit addresses ultrafine processing requirements for flammable and explosive powders and provides a closed grinding unit for powder production lines.

      The disc jet mill generates supersonic airflow by compressed gas. After materials enter the grinding chamber, particles collide and rub against one another to achieve pulverization. No metal grinding bodies directly strike the materials throughout the process, resulting in low temperature rise inside the chamber. After grinding, materials flow with the airflow into the classification zone. Coarse particles remain in the grinding chamber for further processing, while fine particles are carried by airflow into the collection device. The whole machine adopts a closed negative-pressure structure. Powders circulate inside pipelines to minimize outward dust leakage. The intelligent explosion-proof module is equipped with oxygen content monitoring, static grounding and interlock protection mechanisms. When monitored operating parameters exceed threshold values, the equipment triggers shutdown, suitable for processing conditions involving explosive powders. The unit can be connected to an inert gas circulation loop to reduce oxygen concentration inside the chamber for processing oxidizable powders.

      For lithium battery material processing, cathode and anode powders require ultrafine deagglomeration during manufacturing, and the materials are flammable. The intelligent explosion-proof disc jet mill is integrated into lithium powder production lines. Its closed system reduces powder leakage, and the explosion-proof monitoring module continuously tracks chamber conditions. The low-temperature grinding feature preserves the physical and chemical properties of powders. Ground materials are directly collected for the subsequent process. The complete grinding system runs stably during continuous production, catering to multi-batch powder processing tasks of lithium battery material manufacturers.

      In chemical powder production, processing pigments, resin intermediates and certain flame-retardant powders carries risks of dust explosion. The disc jet mill is fitted with explosion-proof motors and explosion venting accessories. Its workshop layout complies with safety specifications for chemical plants. The equipment is easy to disassemble, and the chamber interior is convenient to clean. Residual powder can be quickly removed during material changeover to reduce cross-contamination of different raw materials. Most chemical production lines operate continuously, and this machine can connect with upstream feeding and downstream packaging processes to form a complete powder processing chain.

      For pharmaceutical raw material powder processing, some pharmaceutical intermediates are heat-sensitive and flammable and cannot withstand sustained high temperatures during processing. The disc jet mill achieves pulverization via gas collision and maintains low working temperatures throughout processing to retain the original physical and chemical properties of materials. The closed grinding structure prevents ingress of external impurities, and the supporting explosion-proof protection meets safety management requirements for pharmaceutical powder workshops. It is applicable to both small-batch trial production and large-scale manufacturing, supporting pulverization of raw material batches of varying volumes.

      In non-metallic mineral powder processing, some modified mineral powders are flammable and require safety protection during ultrafine processing. The disc jet mill can adjust air inlet pressure and feed rate to match grinding requirements for mineral powders of different hardness. Closed pipelines reduce dust dispersion and improve workshop working conditions. Featuring a compact structure, the equipment occupies limited factory space and can be easily integrated into existing powder production lines.

Manufacturing of disc jet mills follows powder equipment assembly workflows. Standardized controls are implemented across chamber machining, pipeline welding, explosion-proof electric control assembly and whole-machine testing. Before delivery, units undergo tightness tests, interlock protection tests and material trial runs to verify operating performance. Pipeline configurations and inert gas supporting schemes can be adjusted according to material characteristics to accommodate processing conditions of various powder materials. Products are supplied to lithium battery material enterprises, pharmaceutical raw material processors and mineral powder manufacturers. Installation and commissioning guidance is provided to satisfy equipment procurement demands of production lines for ultrafine processing of explosive-prone powders.
