Granulation Support Equipment
OFEC provides a full range of support equipment covering the entire organic fertilizer production process, including batching systems, crushers, mixers, conveying systems, rotary dryers, rotary coolers, screening equipment, coating machines, and packaging machines. Together with the core granulation equipment, they form a complete equipment ecosystem – helping customers achieve efficient, stable, and sustainable production operations.
Why Support Equipment Matters
1. Ensures Granulation Performance
The granulation rate and pellet quality of the granulator depend heavily on the particle size, moisture content, and mixing uniformity of the incoming materials. Proper crushing, batching, and mixing are prerequisites for successful granulation.
2. Guarantees Final Product Quality
Downstream processes such as drying, cooling, screening, and coating directly affect pellet strength, appearance, storage stability, and ultimately, market acceptance.
3. Enhances Overall Line Efficiency
A well-designed conveying system and seamless integration between equipment determine whether the production line can run continuously and stably – preventing costly downtime caused by material shortages or blockages.
4. Reduces Long-term Operating Costs
Energy-efficient dryers, high-efficiency dust collectors, and other environmental protection equipment can significantly reduce energy consumption and emissions, lowering long-term operating costs while meeting increasingly strict environmental regulations.
5. Enables Full Automation
Through centralized control and interlocking, the complete set of support equipment enables fully automated production from raw materials to finished products – reducing manual intervention and improving production consistency.
Support Equipment Overview
Reduces large lumps to optimal particle size, improving mixing uniformity and granulation rate
After cooling, before coating/packaging
Batching System
The OFEC Automatic Batching System is the precision feeding equipment at the very front of the production line. It continuously and accurately batches 2–8 types of organic materials, conditioners, and additives according to the formulation ratio.
Key Features:
● Supports 2–8 material types with accuracy better than ±0.5%
● Dynamic continuous weighing with real-time automatic feed rate adjustment
● Quick and convenient formulation changes
● Suitable for both pure organic fertilizer and organic-inorganic compound fertilizer production
Crusher
The OFEC Chain Crusher is the size-reduction equipment in organic fertilizer production lines. It crushes fermented organic materials and oversized return particles down to the optimal size for granulation.
Key Features:
● Available in vertical and horizontal models to suit different space and material requirements
● Horizontal dual-rotor design resists clogging when processing high-moisture materials
● Output particle size 80％＜ 1mm – uniform and controllable
● Interchangeable chains and blades to adapt to different material characteristics
Mixer
The OFEC Mixer is the blending equipment in organic fertilizer production lines. It uniformly mixes crushed organic materials, conditioners, and micronutrients according to formulation – providing homogeneous feedstock for granulation.
Key Features:
● Twin-shaft mixer: continuous large-scale production with high mixing uniformity
● Disc mixer: intermittent small-batch production with easy cleaning and quick changeover
● Tight sealing with no dust leakage
● Wear-resistant, non-stick blades with long service life
Conveying Equipment
OFEC Conveying Equipment connects all stages of the production line, ensuring smooth and reliable material flow throughout the entire process.
Key Features:
● Belt conveyor: horizontal or inclined conveying with flexible distance adjustment
● Bucket elevator: vertical lifting – space-saving design
● Screw conveyor: enclosed conveying – ideal for powdery and granular materials
● Simple structure, easy operation, low energy consumption
Rotary Dryer
The OFEC Rotary Dryer is the core drying equipment in organic fertilizer production lines. It reduces the moisture content of granulated pellets to a safe storage level (≤15%), while the tumbling action also rounds and polishes the pellets.
Key Features:
● Drum diameter: 0.8–4.6 meters, capacity: 1–200 TPH
● Customizable lifting flights for optimal thermal efficiency
● Flexible fuel options: oil, natural gas, coal, or biomass
● Can be integrated with dust collection systems to meet emission standards
Rotary Cooler
The OFEC Rotary Cooler is the key cooling equipment in organic fertilizer production lines. It rapidly cools hot pellets after drying to a temperature suitable for packaging – preventing moisture regain and caking.
Key Features:
● Counter-current air cooling design for high cooling efficiency
● Effectively prevents caking and enhances pellet strength
● Stable discharge temperature creates optimal conditions for subsequent screening and packaging
Screening Equipment
The OFEC Rotary Drum Screener is the grading equipment in organic fertilizer production lines. It separates cooled pellets into finished product, fines (returns), and oversize (to be crushed and returned) – ensuring uniform product specifications.
Key Features:
● Screen drum diameter: 0.8–2.5 meters, capacity: 1–30 TPH
● Equipped with cleaning brush device to prevent screen clogging
● Customizable screen openings for precise grading
● Smooth operation with low failure rate
Coating Machine
The OFEC Coating Machine is the value-adding equipment in organic fertilizer production lines. It applies liquid or powder coating agents onto pellet surfaces after cooling and screening – achieving anti-caking, slow-release, or color-enhancement functions.
Key Features:
● Dual-use for liquid and powder coatings with dedicated application systems
● Strip lifting flights ensure thorough tumbling for uniform coating coverage
● Adjustable coating agent dosage to suit different requirements
● Enhances product added value and market competitiveness
Packaging Machine
The OFEC Packaging Machine is the terminal equipment in organic fertilizer production lines. It automatically weighs and bags finished pellets according to set weights.
Key Features:
● Supports multiple packaging formats: ton bags, open-mouth bags, valve bags
● Single-scale or double-scale options with accuracy better than ±0.2%
● Can be integrated with automatic palletizing systems to reduce labor
● Seamless integration with line control systems
