High-Efficiency & High-Precision Mixing for Powders with Extreme Ratio Differences, Matches Hosokawa Performance

Ideal for pharmaceutical, food, chemical, pesticide, feed, petroleum, metallurgy & mining, building materials, and coatings industries.

SHJ Series Conical Screw Blender is a new type of high-efficiency & high-precision mixing equipment. Driven by one motor and cycloidal pinwheel reducer, the machine realizes both revolution and rotation of the screws. By combining the circular motion of long/short mixing screws and their self-rotation, it achieves ideal mixing uniformity for materials with extreme differences in specific gravity and ratio, featuring short mixing time and excellent mixing effect.

Equipment Type

Equipment Type	Screw/Ribbon Quantity & Layout
Single Screw Type Nauta Mixer	One long screw, arranged along the cone wall, with rotation and revolution movement
Double Screw Type Conical Screw Mixer	One long and one short screw, asymmetric eccentric layout, simultaneous rotation and revolution
Triple Screw Type Conical Screw Mixer	One main long screw in the middle + two symmetrical short screws on both sides, three screws running synchronously
Vertical Ribbon Type Vertical Ribbon Mixer	Single continuous ribbon blade, rotating closely along the inner wall of the cone

Main Features

Advanced Structure, Safe & Easy Operation
No bottom bearing on the screw shaft, eliminating failures caused by powder leakage from bottom bearings.
Fast Mixing & High Uniformity
Asymmetric double-screw design (one large, one small) enlarges the mixing range, ideal for materials with great specific gravity difference and special mixing ratio.
- Short mixing time
- High mixing uniformity: CV ≤ 5%
- Complete discharge with no residue
Outstanding Energy Saving
Power consumption is only about 1/10 of drum mixers.
Gentle Mixing Process
No material crushing, abrasion or overheating during mixing.
Stable Final Mixture
No stratification or segregation after mixing.
Dust-Free & Durable
Sealed and dust-free structure, simple operation and convenient maintenance. Long service life. The cone can be customized as a pressure vessel for pressurized or vacuum operation.
Material Options
Available in carbon steel or stainless steel based on customer requirements.

Why Choose Our Conical Screw Mixer?

All components are manufactured by 5-axis machining centers.
Gears adopt American Gleason spiral bevel gear technology, forged with alloy steel, ensuring long-term stable and reliable operation.
Mixing screws for different materials are designed via data comparison and computer modeling.
Different helix angles of screw blades are customized according to material density, fluidity, base material and additives.
Realizes ideal mixing even for materials with an extreme ratio of 1:1000.

Working Principle

The revolution of double screws makes powder move circularly along the cone wall.
The rotation of screw blades pushes powder radially toward the center of the cone.
Powder flows upward inside the cone and discharges along the outer circumference of the screws, mixing along the screw shaft.
The combination of revolution and rotation creates four flow forms: convection, shear, diffusion and infiltration. Thus powder materials can be mixed quickly and uniformly inside the blender.

FAQ: How to Select the Conical Screw Mixer

Step 1: Select Working Capacity

Choose from a batch capacity range of 0.1–30 cbm, and we will recommend the most suitable mixer model based on your volume requirements.

Step 2: Select Contact Materials

Only materials in direct contact with your product are customizable. Non-contact components (motor, reducer, bearings, etc.) use standard industrial-grade materials.
Based on your raw materials, processing conditions, and hygiene standards, available options include: Mild Steel, SUS304, SUS316L, SUS321. Surface treatment is matched to your material characteristics.

Step 3: Determine Motor Power

Motor power is selected based on:
· Material specific gravity
· Material flowability
· Operating mode
Two operating modes:
· Empty start (standard duty)
· Load start (heavy duty)

Step 4: Add Optional Auxiliary Systems

Customize additional functions to match your process:
· Spraying system
· Heating system
· Cooling system

Step 5: Standard Inlet Ports

Each mixer is equipped with standard ports:
· Feeding port
· Cleaning port
· Vent port

Step 6: Choose Discharge & Drive Mode

Select your preferred operation type:
· Manual
· Pneumatic
· Electric
