During the production, transportation, and feeding of zinc powder, enterprises often face challenges such as materials being flammable and explosive, prone to oxidation and caking, dust pollution, and low conveying efficiency. Traditional mechanical conveying methods not only easily cause equipment blockages and material loss, but also pose serious safety hazards, making it difficult to meet the high environmental and safety requirements of chemical production.

Material characteristics

Zinc powder is a silver-gray powder with a density of about 7.1 g/cm³, and particle sizes typically in the range of 5~100 μm. It is highly active, easily oxidized, and easily produces hydrogen gas when exposed to water or moisture. When mixed with air to a normal concentration, it can explode upon exposure to open flames. It has poor flowability and tends to agglomerate, requiring strict sealing, explosion-proofing, and anti-static capabilities of the conveying system.

Product Introduction

The zinc powder pneumatic conveying system provided by Head Powder uses sealed pipeline negative pressure or positive pressure conveying methods, using compressed air as the power source to steadily transport zinc powder from the raw material silo to the process site. The system includes core modules such as feeding devices, conveying pipelines, air source treatment, control valves, and dust separation and removal, enabling fully automated operation according to actual customer conditions to effectively avoid material exposure risks.

Product advantages

Solutions for customer pain points:

• Explosion-proof safety: The system uses explosion relief devices, anti-static pipelines, and inert gas protection designs to reduce explosion risks from the source.
• Sealed with no leakage: fully enclosed pipeline transport prevents dust leakage, improves workshop environment, and reduces material loss.
• Intelligent control: Integrated PLC automatic control system monitors conveying pressure, flow, and material level in real time, enabling more accurate feeding and remote operation.
• Customized solution: Based on zinc powder density, particle size, conveying distance, and site layout, flexibly configure conveying pressure, pipe diameter, and bending angle to help ensure stable and non-clogging conveying.
