Explore our state-of-the-art process equipment, custom manufactured to meet global industrial standards and specifications.
In modern process engineering, the demand for highly efficient, low-shear, and zero-contamination batch mixing has driven the development of advanced conical screw mixers. Historically, processing industries relied heavily on horizontal blenders, which, while robust, often suffered from large mechanical footprints, product retention (dead zones), high power consumption, and mechanical degradation of fragile particulates.
The shift toward conical mixing geometries represents a major breakthrough in bulk solids handling. Conical mixers operate on a three-dimensional mixing principle: a rotating cantilevered screw (or dual screws) orbits along the conical vessel wall while rotating on its own axis. This dual-action motion lifts material from the bottom of the cone to the upper surface, where it flows downward by gravity, creating a highly homogeneous blend with minimal shear stress. This process is particularly critical for fragile materials, crystalline powders, and heat-sensitive additives where maintaining particle structure is paramount.
From a process validation perspective, conical mixers offer distinct engineering advantages that directly influence operational cost and product quality:

Our fabrication processes include steel plate laser profiling, precision CNC bending, CO₂ shielded arc welding, high-purity argon arc welding, robotic structural welding, and multi-stage surface treatments. These technologies work together to ensure outstanding structural integrity, tight engineering tolerances, and continuous product improvement.
For multinational procurement directors and process engineers in the food, pharmaceutical, and chemical sectors, selecting a conical mixer supplier involves evaluating strict operational parameters. We design our custom OEM/ODM solutions to address these core engineering and regulatory requirements:
We implement advanced CIP (Clean-In-Place) systems and design all vessels with zero dead angles, ensuring rapid washdowns and eliminating cross-contamination risks between batches.
Our mixers are available with ATEX Zone 20/21/22 certifications, utilizing explosion-proof motors, pressure relief vents, and dust-tight seals for volatile environments.
We manufacture vessels in SS304, SS316L, and exotic alloys like Hastelloy, with structural dampers (Rubber Dampers + 304 SS) to isolate vibrations and safeguard operational integrity.

Our manufacturing facility and all flour milling, conveying, and conical mixing equipment are fully certified under the ISO9001 quality management system and carry the European CE certificate of compliance. We are deeply committed to sustainable engineering; for example, our grain cleaning lines feature water-free dry processing systems. This approach eliminates industrial wastewater discharge, lowers operational costs, and supports environmental compliance.
In addition, we source premium materials for our mechanical assemblies. This includes specialized Rubber Dampers (available in Natural Rubber, NBR, EPDM, FKM, and HNBR bonded to 304 Stainless Steel) designed to isolate high-frequency vibrations in screening and sifting machinery. This attention to detail extends the operational lifetime of our equipment and reduces maintenance requirements.
As a dedicated industrial solution provider, Henan Jiujie Machine Co., Ltd. delivers comprehensive process solutions tailored to our customers' long-term production needs:
As global processing plants adopt smart manufacturing, we are integrating advanced digital technologies into our conical mixer lines:
We are integrating Near-Infrared (NIR) sensors directly into the conical vessel walls. This allows operators to measure blend homogeneity in real-time, preventing over-mixing and reducing cycle times.
By mounting smart accelerometers and temperature sensors near the drive gearbox and screw bearings, our systems monitor heat and vibration levels. This data helps identify potential issues before they cause unexpected downtime.
Our advanced CIP manifolds feature automated spray ball positioning, wash-water conductivity monitoring, and validation reports to simplify audit compliance in GMP-regulated environments.
