In the field of metal powder processing and transportation, the risk of dust explosions has always been a focal point of industry concern. Head Powder designed and deployed an explosion-proof sealed metal powder conveying system based on the actual working conditions of a metal powder manufacturer in Zhengzhou, Henan, addressing safety hazards, material leakage, and environmental pollution issues found in traditional conveying methods.

Case Background

The company mainly engages in the processing and transportation of flammable and explosive metal powders such as aluminum powder and magnesium powder. The original conveying process combined open belt conveyors with manual handling, which not only caused severe dust overflow but also caused the explosive dust environment to be ineffectively controlled, repeatedly triggering workshop dust concentration alarms, posing challenges to production efficiency and personnel safety.

Customer pain points

• Severe dust: Open conveying causes metal dust to escape, creating a harsh workshop environment and increasing occupational health risks for employees.
• Explosion hazards: Dust such as aluminum powder and magnesium powder pose a risk of ignition and explosion when the concentration in the air reaches normal levels. The original equipment lacks explosion-proof certification and inert protection.
• High material loss: During transportation, particles scatter, become damp, or become contaminated, leading to reduced raw material utilization and persistently high costs.
• Maintenance difficulties: Routine equipment frequently cleans dust, resulting in long downtime and maintenance periods, affecting overall production line efficiency.

Product advantages

Head Powder addresses these pain points by providing a customized explosion-proof sealed conveying system for metal powders. This system uses a fully enclosed pipeline design, combined with nitrogen protection and pressure monitoring, cutting off dust spills and explosion conditions at the source. Specifically:

• Explosion-proof structure: The main body of the equipment is made of stainless steel, and all electrical components are selected according to explosion-proof standards. Equipped with explosion relief devices and flameproof valves, it helps ensure safety and control in extreme situations.
• Sealed conveying: wear-resistant seals are used at pipeline connections, ensuring no leakage throughout the entire conveying process; Selectable negative pressure or positive pressure conveying modes to suit different powder characteristics.
• Intelligent monitoring: Integrates online oxygen content detection, pressure sensing, and automatic nitrogen replenishment system to adjust protective gas concentration in real time, enabling unmanned safe use.
• Easy maintenance design: quick-open access ports and modular components facilitate daily cleaning and maintenance, reducing downtime.

After the system was put into operation, workshop dust concentrations dropped below safety thresholds, material loss rates dropped to within 0.5%, and continuous production line operation time increased by 40%. It provides reliable support for enterprises to achieve safe, clean, and efficient metal powder transportation.
