Technical DatasheetModern industrial complexes demand seamless, contamination-free, and energy-efficient handling of bulk solids, granules, and powders. As a globally recognized industry pioneer, Shandong Zhangqiu Blower Co., Ltd. (ZCBC) leverages over 50 years of specialized manufacturing experience, deep academic integration, and persistent technology innovations to supply and export world-class, custom-engineered Pneumatic Conveying Systems.
By coupling proprietary high-pressure Roots blowers, rotary valves, ceramic slurry pumps, and automated instrumentation loops, ZCBC designs custom conveying solutions that dramatically reduce material loss, minimize structural wear, and slash carbon emissions. Whether transferring fly ash in thermal power stations, conveying toxic raw chemical powders, handling municipal sludge, or feeding dry food grains, our systems optimize the gas-to-solid ratio dynamically to deliver superior performance.
A comprehensive comparative breakdown of pneumatic conveying configurations engineered to manage pressure gradients, saltation velocities, and complex bulk density variations.
Dilute phase conveying utilizes high-velocity air flows (typically 15 to 35 m/s) to keep materials fully suspended in the gas stream. Operating under positive pressure or vacuum, it is highly suited for non-abrasive, light bulk materials with low bulk densities. ZCBC integrates high-volume Tri-Lobe Roots blowers and Centrifugal Fans to maintain a constant, steady pressure gradient across lengthy process pipe runs.
By keeping conveying air velocities extremely low (1.5 to 8 m/s), dense phase systems push cohesive, abrasive, or fragile materials in slugs or dune formations along the pipelines. This is optimized using high pressure-differentials provided by ZCBC TRR two-stage roots blowers or high-pressure screw compressors, preserving raw material state and reducing pipe-wall wear dramatically.
Every ZCBC system installation goes through strict thermodynamic calculations to counter system losses. We integrate specialized divergence valves, rotary airlocks, air filtration units, and baghouse dedusters to configure closed-loop or open-loop circuits depending on environmental regulations and plant requirements.
Discover how our pneumatic conveying designs are customized across global manufacturing and process industries to overcome extreme operating conditions.
In global municipal and chemical wastewater plants, ZCBC Roots blowers supply stable aeration while our conveying solutions transport dewatered sludge cakes, calcium hydroxide, and activated carbon powders. By maintaining consistent pressure, our solutions prevent pipeline blockages and optimize thermal oxidation and stabilization processes.
Conveying chemical polymers, catalysts, and raw minerals requires zero contaminant intrusion. ZCBC designs specialized positive pressure closed-loop pneumatic networks featuring nitrogen-loop recirculation systems, preventing ambient moisture or atmospheric oxygen from degrading volatile compounds.
For mining operations dealing with abrasive slurries and heavy tailings, ZCBC combines ceramic slurry pumps (such as the TZJK-TD Series) and pneumatic ash-handling units. Ceramic elements offer unmatched hardness (up to 9 Mohs scale), maintaining pump integrity and system reliability under relentless abrasive wear.
Modern coal-fired boilers require continuous extraction of fly ash and bottom ash. ZCBC multi-stage and two-stage tandem Roots blowers provide the continuous vacuum or positive pressure needed to clear precipitator hoppers over distances exceeding 1,000 meters to storage silos.
Handling bulk cement, silica sand, and powdered limestone demands high throughput capacities. Our dense phase conveying systems and heavy-duty rotary valves are built to handle hard, highly abrasive materials with minimal equipment wear and zero dust leakage.
ZCBC provides turnkey engineering services including Mechanical Vapor Recompression (MVR) systems, evaporation loops, water purification complexes, and operations & maintenance support, combining advanced hardware with full process engineering capabilities.
ZCBC operates from a highly modernized, high-standard industrial park covering 430,000 square meters. In 2011, we became a public company listed on the Shenzhen Stock Exchange (Stock Code: 002598), a major milestone supporting our continuous technological investment and global market growth.
Our manufacturing capability features over 100 sets of imported, advanced production equipment: CNC machining centers, five-axis machining centers, three-axis measuring systems, CNC machine tools, and ultrasonic flaw detectors from Japan and Germany. These high-precision resources ensure tight structural tolerances and long service lives for every Roots blower and splitter valve we produce.
To accelerate design and production cycles, we employ a modern PLM (Product Lifecycle Management) system, computer-aided design (CAM), and CAPP (Computer-Aided Process Planning) technologies. This digital integration allows us to customize drawings and deliver accurate 3D CAD files within 24 hours of receiving customer specifications.
Our technological growth is led by an expert scientific research team, supported by engineering specialists receiving State Council and municipal government allowances. Through our dedicated doctoral program and professional postgraduate workstation, ZCBC continuously designs and refines industrial air-moving machinery.

A look at the technology roadmap shaping the next generation of industrial pneumatic conveying equipment.
We are integrating real-time pressure, velocity, and acoustic emission sensors along process pipelines. These cloud-connected sensors identify initial signs of pipe blockage or wear, helping plant operators transition from scheduled maintenance to predictive maintenance strategies.
Through computational fluid dynamics (CFD) research, we continue to optimize impeller profiles for our tri-lobe Roots blowers and screw air compressors. Improving internal tolerances and geometry reduces internal slip losses, reducing energy consumption for global users.
With increasing environmental regulations, we are developing closed-loop inert gas recycling systems. These configurations recover all carrier gases during powder transport, preventing volatile organic compounds (VOCs) or fine chemical particulates from escaping into the environment.
Answers to common questions about selecting, designing, and maintaining industrial pneumatic conveying systems.
Dilute phase conveying uses high-velocity air streams (typically 15 to 30 m/s) to keep materials fully suspended in the airflow, making it suitable for non-abrasive, non-fragile materials. Dense phase conveying operates at lower air velocities (1.5 to 8 m/s), pushing materials through the pipe in slugs or dunes. This makes it ideal for handling fragile, abrasive, or heavy materials while minimizing pipeline wear.
Roots blowers function as positive displacement pumps that deliver a constant volume of air against varying pipeline pressures. Their rugged construction allows them to handle fluctuating backpressures from changing material loads, ensuring the system maintains the necessary air velocities to prevent blockages.
We configure systems with highly wear-resistant components. This includes our TZJK-TD series ceramic-lined slurry pumps and pipe bends cast from hard alloys or lined with alumina ceramics. These ceramic components resist wear, extending system service life in demanding conveying lines.
Yes. For food-grade applications, we utilize polished stainless steel pipelines, FDA-approved gaskets, and sanitary rotary airlocks. For hazardous or explosive chemical powders, we design closed-loop, positive-pressure systems that recycle inert nitrogen gas, preventing contact with ambient oxygen and moisture.
To prepare an accurate design, our engineering team needs the material properties (bulk density, particle size, moisture content, abrasiveness), the required conveying rate (tons/hour), the physical routing layout (horizontal and vertical distances, number of bends), and the site power specifications.
Integrating our high-efficiency tri-lobe blowers and variable frequency drives (VFD) helps optimize power consumption. VFD controls adjust motor speeds in real-time based on the system pressure, resulting in energy savings of up to 20-30% compared to traditional single-speed setups.
