Zhengding Environmental Dust Collection System Successfully Integrated Lee & Man Paper Group
Pioneering environmental protection and energy efficiency in the paper-making industry, delivering benchmark projects with meticulous craftsmanship!
Hunan Zhengding Environmental Technology Co., Ltd. has once again secured a landmark project at a major domestic paper mill, providing… Jiangxi Liwen Paper Co., Ltd. A complete set of dust-collection equipment was delivered in a single batch, encompassing dust-collection systems for six 2850 paper machines and six 2850 rewinding machines, for a total of 12 fully installed and commissioned systems.
Lee & Man Paper Group It is a mainboard-listed company on the Stock Exchange of Hong Kong and a large, highly influential integrated pulp-and-paper enterprise in China, with production bases strategically located both domestically and internationally.
Relying on its independently developed technologies, Zhengding Environmental provides end-to-end, customized dust-control solutions that precisely align with the operating conditions of large-scale paper mills, helping paper‑making facilities achieve clean production, low‑energy dust removal, and improved quality and efficiency.
Hunan Zhengding Environmental Technology Co., Ltd. has delivered another benchmark project for a large‑scale domestic paper mill. We have supplied a complete set of dust‑removal equipment to Jiangxi Lee & Man Paper Manufacturing Co., Ltd. in one go, including six sets of dust‑removal systems for 2850‑model paper machines and six sets for 2850‑model rewinders, with a total of 12 systems successfully delivered.

Suitable for the stringent operating conditions of large paper mills.
Part .01
Jiangxi Liwen Paper, a key production base under the Group, operates large-scale, state-of-the-art papermaking lines with substantial capacity and 24-hour continuous operation. The high-speed paper machines and rewinding units, running continuously, readily generate significant amounts of fine paper dust, which conventional dust-collection systems struggle to control effectively, posing persistent dust‑related safety risks.
Large-scale production lines have huge capacity and equipment under heavy load, so high-speed paper machines and rewinders easily produce a lot of fine paper dust during continuous operation.
For the demanding operating conditions of large paper mills, Zhengding Environmental has selected a proprietary wet dust‑removal technology, employing… Venturi tube + A combined spray‑scrubber tower design, featuring a compact structure and efficient operation, can precisely remove fine particulate matter in the 0.1–20 µm range, delivering outstanding dust‑removal performance and fully complying with national environmental emission standards.
Zhengding Environment opts for a specialised wet dust removal technology, using a Venturi tube and spray scrubbing tower combination. The equipment has a simple structure, runs efficiently, and can precisely remove fine dust from 0.1 to 20 microns, achieving remarkable dust purification.
Meanwhile, this technical solution can suppress dust accumulation at the source, significantly reducing the risks of dust ignition and explosion, and is highly compatible with the continuous, high‑load, and stringent production requirements of large paper mills.
Home is a gentle harbour that holds the warmth of life，Free from excessive ornamentation and worldly noise，it outlines the space with clean linesand creates a healing atmosphere with softAt the same time, this technology can prevent dust from accumulating at the source, significantly reducing the risk of dust fires and explosions, and is highly suited for large paper mills with continuous, high-load, and high-standard production needs. colours。Every detail reflects a unique aesthetic style.

Addressing the industry’s hidden production pain points
Part .02
In the papermaking production process, managing fine particulate matter in workshop environments is often an overlooked yet critical weak point for many paper mills. Drawing on years of hands-on experience in dust‑control projects, Zhengding Environmental has developed specialized dust‑removal technologies tailored to the paper industry. By moving beyond the limitations of generic dust‑collection equipment and addressing the unique dust‑generation characteristics of papermaking, we deliver comprehensive, customized solutions that ensure a safe, efficient, and clean modern working environment—effectively controlling dust at its source.
Zhengding Environment focuses on specialised dust removal technology for papermaking, avoiding the limits of general dust equipment and creating professional, custom dust control solutions tailored for the papermaking industry
Dust control at the source, optimizing the working environment.
Precisely identifies the key dust‑generating points on paper machines and rewinders, efficiently captures airborne paper dust and accumulated particulates, significantly reduces dust dispersion in the workshop, eliminates occupational health issues such as throat irritation and eye discomfort, and creates a clean, comfortable, and compliant production environment.
Accurately targeting the main dust-producing points of paper machines and rewinding machines, efficiently collecting airborne and accumulated paper dust, greatly reducing dust spread in the workshop, preventing employees from experiencing throat dryness and eye discomfort, and creating a clean, comfortable, and compliant working environment.
Eliminate potential risks and reduce operational maintenance costs.
It effectively mitigates electrostatic safety risks caused by dust during the operation of high-speed equipment, reduces equipment wear and clogging failures resulting from dust accumulation, significantly lowers equipment maintenance costs and downtime losses, and ensures continuous, stable production-line operation.
Eliminate electrostatic safety hazards caused by dust during high-speed equipment operation, reduce equipment wear and blockages caused by dust accumulation, and significantly cut down on maintenance costs and downtime losses.
Clean operating conditions ensure stable paper quality.
Effectively reduces dust adhesion to the paper surface, thereby preventing… Paper defect Defects are minimized, the rate of defective products is reduced, and hidden production costs associated with dust are effectively mitigated, helping paper mills achieve refined operations and high‑quality output.
Prevent dust from sticking to the paper and causing defects, reduce the scrap rate, and effectively avoid hidden production costs caused by dust.
