Located in the Tabuk region of Saudi Arabia, a major lithium battery material production facility required a highly reliable and contamination-free material handling solution. The core challenge was to transport sensitive lithium battery raw materials—such as lithium carbonate, lithium hydroxide, and cathode precursors—from storage to mixing and processing stations without any dust leakage or cross-contamination. This case study details how Shandong Headpowder Engineering Co., Ltd. (abbreviated as headpowder) designed and implemented a complete dust-free enclosed automatic feeding pneumatic conveying system tailored specifically for the harsh desert environment and strict cleanliness standards of the Tabuk site.
The Tabuk area presents unique challenges: high ambient temperatures, frequent sandstorms, and limited local technical support. Conventional feeding methods, such as manual bag dumping or open screw conveyors, would expose lithium battery materials to moisture, dust, and cross-contamination, leading to batch quality issues and safety hazards. Headpowder recognized that a Saudi pneumatic conveying solution must be robust, corrosion-resistant, and fully enclosed to maintain product purity. The system needed to handle fine powders with low bulk density, prevent particle degradation, and operate reliably under extreme heat. By integrating Tabuk pneumatic conveying expertise with local environmental data, the engineering team designed a custom lithium battery material pneumatic conveying system that meets both international safety standards and Saudi industrial regulations.
The core of the project is a dust-free enclosed automatic feeding pneumatic conveying system that uses dense-phase vacuum conveying technology. Materials are drawn from 1-ton big bags or 25 kg bags through a sealed bag dump station equipped with a dust collector. The headpowder system features a unique rotary valve with a nitrogen purge to prevent oxidation and moisture ingress. All conveying pipelines are made of 304L stainless steel with a Ra ≤ 0.8 μm internal surface finish to minimize material adhesion. The system automatically sequences multiple feeding points, delivering precise amounts of lithium battery raw materials to mixing tanks, ball mills, and granulation units. A PLC-based control system monitors pressure, flow rate, and filter differential pressure in real time, ensuring consistent dust-free enclosed automatic feeding operation without manual intervention.
To achieve true dust-free enclosed automatic feeding, the headpowder team incorporated several proprietary components:
All components are designed for easy cleaning and maintenance, with quick-release clamps and washdown-capable surfaces. The entire system is enclosed in a positive-pressure climate-controlled room to protect against desert sand and humidity. This lithium battery material pneumatic conveying solution ensures that every gram of raw material is accounted for, with less than 0.1% loss during transfer.
Since commissioning, the Tabuk pneumatic conveying system has demonstrated exceptional reliability. The facility reports a 30% reduction in material waste compared to previous manual feeding methods. Dust emissions measured at the bag dump station are below 0.5 mg/m³, far exceeding Saudi environmental standards. The headpowder system operates continuously for 20 hours per day with only scheduled preventive maintenance every 500 hours. The automatic feeding accuracy is within ±0.5% of target weight, critical for consistent lithium battery cathode production. The Saudi pneumatic conveying application also includes remote monitoring via a cloud-based IoT platform, allowing the Tabuk plant managers to track performance, receive alerts, and optimize parameters from their control room.
Shandong Headpowder Engineering Co., Ltd., based in China Shandong, has over 15 years of experience in designing and manufacturing pneumatic conveying systems for the chemical, pharmaceutical, and battery materials industries. The headpowder team combines deep process knowledge with advanced fabrication capabilities, delivering turnkey solutions from concept to commissioning. For the Tabuk project, the company provided full support including on-site installation supervision, training, and a 2-year warranty. The dust-free enclosed automatic feeding pneumatic conveying system is now a benchmark for lithium battery material handling in the Middle East.
