An electronic materials company in Dongguan needs to transport nano silica powder from the raw material silo to multiple feeding points on the production line during production. The company originally used manual handling and open lifting equipment, but the working environment faced issues such as dust dispersion and material loss, and production efficiency was limited by manual operation. After extensive investigation, the company selected the negative pressure pneumatic conveying system provided by Head Powder, achieving a fully sealed, automated, and low-loss powder conveying solution.

Customer pain points

1. Severe dust pollution: Nano silica powder has small particle size and light weight, making it easy to generate dust during handling and discharging, which not only affects workshop air quality but also poses health risks to operators.
2. High material loss: The open conveying method causes powder to drift and remain during transportation, with annual loss rates exceeding 5%, increasing production costs.
3. Limited production efficiency: Manual handling is slow, making continuous feeding difficult, and frequent manual cleaning consumes a large amount of man-hours, making it impossible to meet the production line's demand for stable and continuous feeding.
4. Frequent equipment blockages: Nanopowders easily absorb moisture and agglomerate, so traditional mechanical conveying equipment frequently experiences blockages, leading to frequent downtime for maintenance.

Product advantages

To address these pain points, Head Powder has designed and implemented a negative pressure pneumatic conveying system for Dongguan enterprises. The specific advantages are as follows:
1. Fully enclosed negative pressure conveying: Uses a negative pressure extraction method, keeping the entire conveying pipeline under negative pressure. Powder flows within the sealed pipeline, preventing dust leakage from the source and significantly improving the workshop environment.
2. Low loss and high efficiency: The system operates stably, with almost no material residue during conveying, and the loss rate controlled below 0.5%; At the same time, it enables automatic switching between multiple feeding points, with a single-hour conveying capacity of up to 2 tons, improving production efficiency.
3. Intelligent control and anti-clogging design: Equipped with a PLC automatic control system, it can monitor pipeline pressure, material level, and flow in real time, and features reverse blowing cleaning functions, effectively preventing powder accumulation and blockage, reducing human intervention and downtime for maintenance.
4. Strong adaptability and easy maintenance: The system is optimized for the physical properties of nano silica, using wear-resistant pipelines and dedicated sealing valves, capable of handling powders with particle sizes of 20~100nm and bulk density of 0.1~0.4g/cm³; The modular structure makes daily maintenance simple and fast, reducing operation and maintenance costs.
