      In the powder processing industry, some materials are prone to safety hazards caused by friction, static electricity and other factors during pulverization. Conventional grinding equipment cannot handle the grinding of such materials, limiting the range of processable materials for powder production lines. Traditional pulverizers lack integrated explosion-proof structures. When processing combustible raw materials, multiple protective measures must be added for workshop production, raising on-site production management costs. As an explosion-proof powder processing and grinding equipment, the QSF-120 Jet Mill operates on the principle of jet pulverization. High-speed gas streams drive materials to collide with one another for size reduction, minimizing direct friction between materials and mechanical components. It is suitable for processing various flammable and explosive powders.

      The whole machine adopts an explosion-proof structural design and is built in compliance with relevant explosion-proof specifications. It is equipped with anti-static and explosion venting assemblies to reduce static accumulation during processing. There are no high-speed rotating grinding discs inside the equipment chamber. Material breakage is achieved through particle-to-particle collision, lowering the probability of ignition sources generated by friction of metal parts. The control system is fitted with an operation monitoring module that captures real-time equipment operating parameters. Protective actions will be triggered under abnormal working conditions to reduce risks of production line operation. The equipment chamber can be modified for inert gas protection. Media such as nitrogen can be introduced to displace air inside the chamber, further adapting to pulverization of materials with low ignition points.

      For chemical production scenarios, this equipment can be used for powder processing of various chemical raw materials. Many chemical powders react when exposed to open flames or static electricity, imposing strict requirements on equipment safety structure during processing. The QSF-120 Jet Mill can complete pulverization and classification of raw materials, delivering powders with stable particle size distribution. The equipment can be integrated into automated production lines to operate continuously with feeding, collection and packaging sections, supporting mass powder production for chemical enterprises. The closed processing chamber reduces powder escape, lessens dust accumulation in workshops and improves the on-site working environment.

      For pharmaceutical intermediate processing, some pharmaceutical powder raw materials are combustible, and production workshops enforce strict requirements on explosion-proof ratings. The closed-loop inert gas processing mode isolates oxygen in the air to avoid risks during processing. Internal disassembly and cleaning of the equipment are convenient, and the chamber can be easily purged to mitigate cross-contamination between different batches. It supports alternating processing of multiple raw material grades and meets multi-variety production schedules of pharmaceutical intermediate manufacturers.

      For new energy material processing, many lithium battery-related powder materials carry safety risks during pulverization, and production workshops require explosion-proof processing equipment. The QSF-120 Jet Mill is suitable for grinding and classifying such powders. The complete system runs in a closed loop; powder processing and collection take place inside pipelines to reduce contact between powder and the external environment. Process parameters can be adjusted according to production requirements to satisfy pulverization demands of different materials. Matched dust collection devices recover powder and cut material loss.

      In the pesticide powder processing sector, rising dust concentration during powder formulation processing creates hazards, making explosion-proof equipment a necessity for production sections. The closed processing feature of the equipment controls outward dust diffusion. Its matched explosion-proof electrical components comply with usage requirements for workshop explosion hazard areas. It can be retrofitted and installed on existing production lines without extensive adjustment of plant layout, shortening the production line renovation cycle.

      The equipment features a split layout, with the main grinding unit, classification assembly and collection device arranged independently for easy maintenance and inspection. All components undergo working condition tests during production to guarantee long-term continuous operation. Custom process solutions are available based on customers’ material properties and workshop conditions to assist with equipment installation and commissioning, catering to production demands of powder processing plants of all sizes. The equipment can be combined with feeding systems, dust removal systems and inert gas supply units to build a complete explosion-proof powder grinding production line for ultra-fine processing of a wide range of combustible materials.
