Wet extrusion and cylindrical forming of compatible catalyst formulations.
Wet Extrusion Granulator
Intermeshing Gear Wet Extrusion Granulator
The Intermeshing Gear Wet Extrusion Granulator continuously compacts suitable powder between counter-rotating gears and extrudes it through forming holes into uniform cylindrical granules. Designed and manufactured for catalysts and auxiliaries and additives. Review the working principle, performance features and available configuration details below when specifying your industrial project.

Technical Data
Technical specifications
Reference pitch-circle diameter and drive-power values for the three intermeshing gear wet extrusion granulator configurations. Confirm material conditions and final configuration before selection.
| Model | Pitch circle diameter (mm) | Drive power (kW) |
|---|---|---|
| Model 1 | 100 | 7.5 |
| Model 2 | 180 | 15 |
| Model 3 | 360 | 30 |
Granulation yield and finished-product quality depend on formulation, feed moisture, binder, forming-hole diameter and operating conditions. Final equipment selection is subject to material testing and engineering confirmation.
Applications
Intermeshing Gear Wet Extrusion Granulator: industrial applications
Applications include catalysts and auxiliaries and additives. Confirm material properties and process conditions before selecting the equipment configuration.
Auxiliaries and additives
Industrial auxiliaries and functional additives requiring strong, uniform granules.
Daily chemical products
Suitable household and personal-care chemical formulations after process evaluation.
Agrochemicals
Compatible pesticide formulations requiring controlled cylindrical granule size.
Other conditioned powders
Additional wet powder systems with suitable cohesion, flow and extrusion behavior.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Material feeding
Conditioned powder is introduced through the feed hopper and enters the tooth spaces.
Tooth-space filling
The material is carried into the converging zone between the main and driven meshing gears.
Intermeshing compression
The changing internal volume during gear engagement compresses the wet powder.
Root-hole extrusion
Developed pressure forces the compacted material through forming holes at the tooth roots.
Cylindrical granule formation
The extrudate forms cylindrical granules of the selected diameter for collection or downstream processing.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
Intermeshing-gear extrusion
Volume reduction between the engaging teeth compresses the feed and forces it through the root holes for continuous granule formation.
Wet granulation process
Designed for conditioned powder systems whose inherent cohesion or added binder supports extrusion.
Short material residence time
Rapid tooth-space compression and discharge limit the duration of mechanical action on the material.
High granule strength
The published process produces mechanically strong granules with consistent length.
Selectable granule diameter
Forming-hole selection provides nominal product diameters from Φ2.0 to Φ8.0 mm.
Uniform cylindrical product
Controlled extrusion produces cylindrical granules with a comparatively consistent specification.
High granulation yield
The documented granulation yield is at least 95% under suitable material and operating conditions.
Broad application range
The machine can process compatible catalysts, auxiliaries, additives, daily chemical products and pesticides.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
Feed hopper
Introduces conditioned powder uniformly into the gear tooth spaces.
Main intermeshing gear
Provides the primary driven surface for conveying, compressing and extruding the material.
Driven intermeshing gear
Meshes with the main gear to create the changing volume and extrusion pressure.
Root-hole forming pattern
Determines the nominal cylindrical granule diameter within the available Φ2.0–Φ8.0 mm range.
Transmission assembly
Synchronizes the gear pair and supplies the required torque.
Granule discharge
Releases formed granules for subsequent drying, screening or packaging as required.
