Biological & Magnetic Fertilizer Granulation Plant with Room-Temperature Dry

Traditional steam or rotating drum granulation methods generate high thermal friction that kills beneficial living bacteria and disrupts magnetic particle alignments. Our newly developed Biological & Magnetic Fertilizer Double Roller Granulation Plant completely solves this problem by using advanced cold-press technology.

Driven by a specialized bio fertilizer granulator, this complete line processes materials entirely at room temperature without adding water or steam. It provides the ideal waterless dry compaction environment to merge active bacterial cultures and magnetic minerals into high-density granules, protecting organic microbial activity and helping modern agricultural factories capture premium eco-fertilizer market shares.

• Maximum Biological Culture Protection: Operates via room-temperature dry mechanical squeezing, ensuring zero thermal degradation and preserving the survival rate of delicate soil microbes.
• Specialized Anti-Caking Structural Engineering: Designed specifically for magnetic fertilizer machinery, utilizing non-magnetic stainless steel components in key zones to prevent fine mineral powders from sticking to the frames.
• Fluidless Dry Granulation Matrix: Bypasses the need for liquid binders or chemical catalysts, preserving the natural biochemical integrity and purity of your organic-inorganic soil blends.
• Sealed Low-Emission Architecture: The entire bacterial fertilizer line runs under a fully enclosed negative-pressure design, preventing living spore cultures or chemical dust from leaking into the facility air.

• Production Capacity: 1 - 4 Tons/Hour (Optimized for premium bio-organic and functional nutrient batching)
• Core Technology: Low-Temperature Dry Compaction & Low-Friction Granule Sizing
• Target Raw Materials: Beneficial biological bacteria, active enzymes, magnetic mineral powders, urea, and organic meal
• Particle Dimensions: 2mm - 5mm uniform granular finish (Pillow, sphere, or tablet styles available)
• Operational Framework: Centralized automated PLC control matrix featuring independent motor amperage monitoring

This advanced biological and magnetic fertilizer machinery line runs on an automated, low-temperature continuous processing cycle:

1. Sealed Dust-Free Powder Intake: Fine magnetic trace powders and living biological ingredients are vacuum-conveyed into independent storage bins to prevent cross-contamination and dust leaks.
2. Cool-Cycle Homogeneous Blending: The bulk ingredients drop into a slow-speed horizontal mixer that uses specialized low-friction paddles to combine the active cultures and chemical elements uniformly without generating frictional heat.
3. Constant Vertical Force Feeding: The mixed dry powder moves via an enclosed vertical elevator straight into the bio fertilizer granulator's feeding throat, where a variable-speed stuffing screw removes air pockets.
4. Room-Temperature Double-Roller Compactor: The de-aerated powder passes between two high-precision counter-rotating alloy rollers. Under immense hydraulic squeezing forces, the powder instantly undergoes dry physical compaction, leaving the rollers as solid flakes.
5. Gentle Mechanical Flake Crushing: The dense sheets drop immediately into a built-in miniature crushing mill, where rotating slow-speed claw teeth gently crack and slice the sheets into small raw fragments.
6. High-Frequency Dual-Deck Screening: The fragments travel straight through an enclosed rotary screening machine to extract standard commercial granules. Qualified particles (2-4mm) flow toward the final packaging stage.
7. Automated Material Reclamation Loop: All undersized fine powder passing through the sieve screen is caught by a bottom collection hopper and instantly re-routed via an enclosed loop back to the primary vertical screw for 100% waste-free recycling.
8. Direct Bulk Packaging & Bagging: Because this bacterial fertilizer line uses pure dry compaction, the output granules require zero cooling or drying time and move directly into an automated packaging station for rapid 25kg/50kg packing.
