Compost Granulating Machine: Industrial-Grade Organic Fertilizer Pelletizing System

Henan Yuxing's compost granulating machine delivers proven performance backed by over 20 years of fertilizer equipment manufacturing expertise. Our XGZG series processes 3–15 tons per hour with a granulation rate exceeding 95%, transforming fermented organic waste into commercial-grade spherical pellets.

Engineered with variable-frequency motor control (7.5–22 kW) and wear-resistant alloy steel components, these machines handle moisture content from 25% to 35% efficiently. With inner diameters ranging from 1500 to 2200 mm and adjustable installation angles of 2–5°, you can customize output to match your production goals. Our equipment serves clients across 50+ countries, supported by rigorous quality testing from Chinese technical supervision bureaus and agricultural machinery certifications.

How It Works

The compost granulating machine uses rotary drum technology to convert loose organic matter into uniform granules through controlled mechanical action.

Pre-fermented compost enters the rotating cylinder at a precise feed rate. As the drum rotates at 10.5–14 revolutions per minute, materials tumble continuously along the inner wall lined with wear-resistant rubber or alloy steel.

The slightly inclined installation angle (2–5°) creates natural material flow from input to discharge. Internal flights lift and cascade materials, creating ideal conditions for particle collision and adhesion. Centrifugal force and moisture naturally bind organic particles into spherical shapes.

The friction-generated heat (50–70°C) helps reduce moisture content while sanitizing the final product. No binders are required for pure organic materials—the natural cohesive properties of decomposed matter create stable pellets. The entire granulation process completes within 8–12 minutes per batch cycle.

Technical Specifications

Key Advantages for Your Production

Energy-Efficient Operation

Variable-frequency drive technology reduces power consumption by up to 30% compared to fixed-speed systems. The optimized rotation speed minimizes mechanical stress while maximizing throughput, lowering your operational costs per ton.

Superior Durability in Harsh Environments

Alloy steel granulation components resist corrosion from high-ammonia livestock manure and abrasive agricultural residues. Typical wearing parts last 1,500–3,000 operating hours before replacement, reducing maintenance downtime.

Flexible Material Processing

Handle diverse feedstocks including pig manure, poultry droppings, municipal sludge, crop straws, and fruit processing residues. The adjustable angle and speed accommodate materials with varying fiber content and adhesive properties.

Fast Delivery Timeline

Standard models ship immediately from stock. Custom configurations tailored to your voltage requirements, control systems (Siemens/Schneider PLC), and CE certification needs deliver within 15–20 days.

Integrated Solution Compatibility

Seamlessly connects with our complete production line equipment including crushers, mixers, dryers, and packaging systems. You receive factory planning, process design, and operator training as part of our turnkey approach.

Application Scenarios

Livestock Waste Valorization Centers

Process high-volume pig and poultry manure into marketable organic fertilizer. The corrosion-resistant construction withstands ammonia-rich environments typical of intensive animal farming operations.

Municipal Biosolid Treatment Facilities

Transform treated sewage sludge into landscaping-grade pellets. Variable moisture tolerance handles the inconsistent water content common in municipal waste streams.

Agricultural Cooperative Processing Plants

Convert seasonal crop residues—rice husks, corn stalks, wheat straw—into value-added organic amendments. The robust design maintains high throughput despite abrasive lignocellulosic materials.

Organo-Mineral Fertilizer Manufacturing

Blend fermented compost with NPK additives to create fortified compound fertilizers. Precise granulation ensures uniform nutrient distribution in every pellet for precision agriculture applications.

FAQ

Q1: What moisture content works best for granulation?

A: The ideal range is 25–30%. Below 20%, materials won't bind properly. Above 35%, pellets become overly sticky and may clog the discharge.

Q2: How do I increase pellet hardness?

A: Adjust the drum's rotation speed and installation angle to extend residence time. For fibrous materials, a small amount of natural binder (bentonite or lignosulfonate) can enhance cohesion.

Q3: Can the machine process 100% organic matter?

A: Yes. Properly fermented compost contains natural adhesive compounds that form stable granules without synthetic binders. The friction heat further strengthens particle bonds.

Q4: What determines wearing part lifespan?

A: Material abrasiveness and operational hours. Processing soft animal manure extends part life beyond 3,000 hours, while woody agricultural waste may require replacement around 1,500 hours.

Q5: Does ambient temperature affect performance?

A: The machine operates effectively in all climates. Internal friction naturally generates 50–70°C heat, which aids moisture reduction and pathogen elimination regardless of external conditions.
