Pneumatic Zinc Powder Conveying Solution

During the production and use of zinc powder, enterprises often face issues such as dust swirling, material oxidation and deterioration, frequent pipeline blockages, inaccurate weighing and measurement, and safety hazards caused by personnel contact. Traditional conveying methods struggle to balance efficiency and safety, easily causing material loss, high equipment downtime and maintenance costs, and even triggering explosion risks, affecting the stability of continuous production.

Material characteristics

Zinc powder is a high-density, fine-grained powder, with particle sizes typically ranging from several tens to several hundred microns, exhibiting typical oxidizing properties and flammability, as well as explosive and flammable properties. Its fluidity is greatly affected by humidity, static electricity, and particle shape. During transportation, oxygen content, humidity, and speed must be strictly controlled to prevent dust cloud concentrations from reaching explosive limits, while also preventing severe friction between the material and the pipe wall and causing static sparks.

Product Introduction

Head Powder provides customized pneumatic conveying system solutions tailored to the unique physical and chemical properties of zinc powder. The system uses sealed pipelines for transportation, utilizing compressed air or inert gas as the power source to smoothly transport zinc powder from the storage silo to the point of use. The overall design includes modules such as positive pressure/negative pressure conveying, automatic mixing, intelligent weighing, pulse reverse blow dust removal, and explosion-proof pressure relief. These modules can be flexibly configured according to customer production capacity, workshop layout, and material characteristics to achieve fully automated and unmanned operation.

Product advantages

To address customer pain points, this solution offers the following core values:

• Fully sealed conveying, zero leakage: All system pipelines use flange connections and are equipped with sealing gaskets to prevent dust leakage, improve the working environment, and reduce material loss.
• Explosion-proof safety design: Equipped with multiple safety devices such as electrostatic grounding, inert gas protection, explosion-proof valve, and vent outlet, meeting relevant explosion-proof standards to eliminate the risk of combustion and explosion at the source.
• It is relatively accurate and controllable: Equipped with high-precision weighing sensors and variable frequency adjustment devices, enabling real-time online measurement and flow regulation, helping to stabilize the mix ratio and reduce human error.
• Reduces clogging and wear: By optimizing the pipeline curvature radius, selecting wear-resistant ceramic liners, installing fluidization devices, and installing plugging and blowing blows, the frequency of clogging is reduced and equipment lifespan extended.
• Intelligent operations and maintenance: Integrates PLC control system and touch screen, real-time monitoring of key parameters such as pressure, flow, and temperature, automatically alarms and records operation data, supports remote monitoring, and reduces manual inspection intensity.
