The Jingzhou Aerogel Powder Dust-Preventing Conveying Project in Hubei, implemented by Head Powder, is an integrated sealed conveying system specially designed for the characteristics of aerogel powder materials. This project solves the long-standing problems faced by manufacturers such as severe pollution during transfer of high-flair powders and high material loss, achieving clean, efficient, and low-loss powder conveying operations.

Project Background

Due to its ultra-lightweight, porous, and high specific surface area, aerogel powder is widely used in thermal insulation, adsorption, catalysis, and other fields. However, these powders have extremely fine particle size and light weight, making them prone to generating large amounts of dust during traditional open conveying. This not only causes material waste but also seriously pollutes the workshop environment, affects employee health, and puts pressure from environmental protection authorities. An aerogel manufacturer in Jingzhou, Hubei (hereinafter referred to as the "Customer") originally used a combination of manual feeding and simple pneumatic conveying methods, resulting in long-term excessive dust concentrations and a high material loss rate per ton of product, urgently needing a customized dust prevention solution.

Customer pain points

Customers mainly face the following challenges during the production process:

• Severe dust: Large amounts of dust are dispersed throughout the material feeding, transportation, and packaging stages of aerogel powder, and the air quality in the workshop cannot meet standards.
• Large material loss: Drifting during conveying leads to low actual material utilization, directly increasing production costs.
• Equipment easily clogs: The powder is extremely light and contains static electricity, making traditional conveying pipelines prone to adsorption and wall hanging, and frequent clearing affects production efficiency.
• Environmental compliance pressure: Local environmental departments have strict limits on dust emissions, and existing equipment cannot meet emission standards.

Solutions and product advantages

To address these pain points, Head Powder provides customers with a fully enclosed pneumatic conveying system, achieving full-process dust control from source to end. The system uses a negative pressure dense phase conveying method, combined with an automatic back-blow cleaning device, electrostatic conduction removal module, and intelligent frequency conversion control unit, ensuring no dust leakage, foreign matter contamination, and pipeline blockages during conveying. At the same time, the system integrates an online monitoring module that provides real-time feedback on key parameters such as conveying volume, air pressure, and dust concentration, making remote control convenient for operation and maintenance personnel.

Compared to traditional solutions, this product has the following application features:

• Reliable sealing performance: pipeline joints use quick-install sealing structures, with overall airtightness rigorously tested, and dust leakage levels below industry average.
• Accurate energy consumption control: Through variable frequency drive and intelligent adjustment, the system can automatically match operating power according to actual load, saving about 15%~20% energy compared to traditional equipment.
• Low maintenance cost: The interior uses a wear-resistant anti-static coating and is designed with a quick service port, reducing downtime and cleaning time.
• Strong adaptability: Can handle ultra-light powders with a wide particle size range (0.1~500μm) and bulk density as low as 0.02g/cm³, with conveying distances exceeding 200 meters.

Project Results

After the system was put into operation, dust concentration in the customer's production workshop dropped to below 2mg/m³, material loss rate was reduced to below 0.5%, conveying efficiency increased by more than 40%, and the system successfully passed environmental inspection. With solid engineering experience and customized technology, Head Powder provides a feasible model for clean conveying in the aerogel industry.
