High-capacity engineered equipment designed to withstand rigorous European operational environments.
The Czech Republic remains one of Europe's central manufacturing and industrial engine houses. With historical centers of engineering in Prague, Brno, and Plzeň, along with a deep agricultural belt across South Moravia, the demands for automated material handling have scaled rapidly. Modern industrial plants are transitioning away from high-maintenance mechanical conveying (such as bucket elevators and screw conveyors) due to critical limitations: dust emissions, high component wear, spatial inefficiency, and the lack of automated control integration.
Jiujie Machine addresses this modern industrial transition by designing specialized pneumatic conveying systems engineered to support high-efficiency operations. Our systems offer airtight transport pathways that eliminate dust emission hazards and minimize floor-space demands. For Czech chemical, food processing, glass manufacturing, and energy generation companies, upgrading to an enclosed pneumatic piping network translates directly to enhanced workplace safety, localized compliance, and lower maintenance budgets.
A properly engineered pneumatic system relies on choosing the correct gas-to-solids loading ratio, pipeline velocity, and pressure envelope. Jiujie Machine designs both primary technical configurations:
Dilute phase conveying is characterized by high air velocity (typically 15 to 30 m/s) and lower system pressures (under 1 bar). The material is suspended completely in the air stream. Best Suited For: Non-abrasive, light powders, or granules such as wheat flour, feed pellets, and low-density chemical additives. Advantages: Economical capital cost, simple operations, highly flexible routing for complex pipeline layouts over short to moderate distances.
Dense phase systems operate below the saltation velocity of the material, using low velocity (typically 2 to 8 m/s) and high pressure (up to several bars). The material moves as plugs or slugs through the pipeline. Best Suited For: Highly abrasive materials (like quartz sand, fly ash, cement) or extremely fragile products (like polished rice or delicate crystalline chemical products). Advantages: Drastically reduced pipe wear, minimized product degradation, and high energy efficiency over long-distance routes.
"By controlling the solid-to-gas ratio (loading ratio) and optimizing air velocities based on the unique fluidization dynamics of local materials, Jiujie systems achieve up to 35% lower energy consumption compared to standardized generic conveyor machinery."
Industrial applications are not one-size-fits-all. Jiujie’s custom engineered layouts solve specific material challenges across key Czech sectors:
For industrial engineering equipment imported into the European Union, meeting safety, environmental, and engineering standards is mandatory. Henan Jiujie Machine Co., Ltd. has established rigorous validation systems to ensure all equipment operates seamlessly in the Czech Republic:
CE & ISO Certification: Our manufacturing processes and structural machinery comply fully with the EU Machinery Directive (2006/42/EC). Every electrical cabinet and motor is configured to support the standard 3-phase 400V/50Hz voltage typical of Czech power grids, using top-tier components like Siemens or Schneider Electric.
ATEX Dust Explosion Mitigation: Materials like sugar, starch, flour, and coal dust pose explosive risks when suspended in air. Jiujie configures ATEX-compliant systems with grounding straps, explosion venting panels, spark detection sensors, and flame barriers, ensuring complete safety compliance under EU ATEX 137 and ATEX 95 regulations.
Environmentally Friendly Processes: Our specialized grain cleaning and dry transport layouts run entirely water-free. This removes the cost and operational footprint of industrial wastewater treatment, aligning with the Czech Ministry of the Environment's green manufacturing incentives.
Essential sub-assemblies and integrated vacuum systems optimized for precise bulk handling.

Combined with our advanced internal CNC infrastructure, we pass these efficiencies down to European buyers, delivering German-standard engineering precision with highly competitive pricing structures.
Selecting a pneumatic conveyor system requires analyzing specific chemical and physical characteristics of your product:
Bulk Density and Particle Size Distribution: Dense powders (like quartz sand or cement, with densities >1.5 g/cm³) require specialized fluidization or high-pressure dense phase transport. Light powders (like flour, <0.8 g/cm³) can easily be moved via dilute phase vacuum paths.
Pipeline Path and Elevation Transitions: Every elbow in a pneumatic piping setup introduces a friction-induced pressure drop. Our engineering team designs optimized routings using AutoCAD modeling software to calculate pressure losses, selecting the correct blower or vacuum pump size (KW rating) to prevent line plugs.
Integration of Rotary Airlock Valves: High-efficiency conveying depends on maintaining a pressure boundary. Our high-precision CNC-machined VCF and LGFWF series rotary airlock valves minimize clearance (typically <0.1 mm) to stop high-pressure gas from blowing back into upstream silos.
From components to heavy-duty dry bulk transport setups, engineered to meet the highest industry standards.
