Product Description
Dry Powder Double Roller Extrusion Granulation Production Line
Product Introduction

Adding water to fine chemicals often triggers unwanted chemical reactions, sticky equipment, and heavy thermal drying overheads. Our newly upgraded Dry Powder Double Roller Extrusion Granulation Production Line solves this industrial bottleneck by utilizing pure mechanical compaction. This advanced dry granulation machine requires zero water, steam, or liquid binders during the entire cycle. By forcing dry powder to granule compaction through extreme physical force, this waterless fertilizer granulator yields robust, high-density particles that are instantly ready for storage, completely changing the efficiency of compound chemical and fertilizer processing.

Dry Powder Double Roller Extrusion Granulation Production Line overview
Key Performance Features
  • Pure Waterless Compaction Technique: Eliminates the risks of material hydrolysis or chemical decomposition by executing a 100% dry powder-to-granule transformation.
  • Extreme Hydraulic Pressure Control: The heavy-duty rollers are backed by an adjustable hydraulic system, creating maximum material density and exceptional particle crush strength.
  • Dust-Free Enclosed Architecture: The entire dry granulation machine operates under a fully sealed negative-pressure design, preventing powder leakage and keeping the factory floor clean.
  • Advanced Roller Cavity Customization: Roller molds can be customized with various pocket designs to produce spherical, oval, square, or specialized tablet shapes based on commercial needs.
Technical Specifications
  • Production Capacity: 2 - 10 Tons/Hour (Heavy-duty continuous industrial scale)
  • Operational Method: Pure Mechanical Dry Compaction & Hydraulic Flaking
  • Maximum Input Moisture: Below 5% (Optimized for moisture-sensitive chemical salts)
  • Granule Output Dimensions: 2.5mm - 6mm uniform solid particles (Adjustable)
  • Roller Shell Engineering: Hardened chromium-molybdenum alloy with specialized anti-stick treatment
Technical details of dry granulation production line
Step-by-Step Mechanical Operation Breakdown

This waterless fertilizer granulator relies on an automated, high-pressure continuous cycle to convert bulk powders into premium granules:

1. Vacuum-Assisted Powder Feeding Raw industrial powders and chemical salts are transferred into the feeding hopper via a screw conveyor equipped with air-venting channels to eliminate air pockets in the material.
2. Forced Vertical Pre-Compression An internal vertical packing screw pre-compresses the loose dry powder, degassing the material and forcing it evenly into the high-pressure roller feeding throat.
3. Hydraulic Double-Roller Compactor The pre-compressed powder passes between two high-precision counter-rotating rollers. Under massive hydraulic squeezing forces, the powder instantly undergoes compaction, leaving the rollers as solid, high-density sheets.
4. Primary Flake Granulating The dense sheets drop directly into a coarse granulating system, where rotating breaker bars crush the hard flakes into smaller, manageable fragments.
5. Fine Granule Sifting & Shaping The broken fragments enter a secondary sizing mill where they are shaped into uniform granules before dropping into a dual-deck rotary screening machine.
6. Precision Particle Separation The sifter separates qualified granules (2-4mm) from fine dust and oversized chips. Standard particles move straight to the final processing line, while oversized parts are sent back for a quick re-crush.
7. Automated Material Reclamation All undersized dry powder caught by the sifter is collected by a bottom hopper and instantly re-routed via an enclosed elevator back into the main feeder for zero-waste recycling.
8. Direct Bulk Packaging & Storage Because the process uses no water, the qualified finished granules are immediately directed to an automated bagging system for 25kg/50kg packing, requiring no cooling or drying lag time.
