Driven by global sustainable agriculture and environmental regulations on livestock waste management, transforming poultry manure, cattle dung, crop straw, and food waste into high-grade organic fertilizer has become a lucrative investment. An organic fertilizer production line is a comprehensive system of complete fertilizer processing machinery designed to convert raw organic waste into commercial powder or granular fertilizers through controlled composting, crushing, mixing, granulation, drying, cooling, and packaging.

As a leading organic fertilizer equipment manufacturer and fertilizer equipment manufacturer, Taian Hongxin Environmental Protection Equipment Co., Ltd. provides customized organic fertilizer production lines ranging from 10,000 to 200,000 tons per year for clients worldwide.

I. 2 Primary Processing Routes for Organic Fertilizer Lines

Depending on the targeted end-product form, organic fertilizer lines are divided into two main categories:

1. Powdered Organic Fertilizer Line (Low CapEx & Fast Setup)

• Ideal For: Startup plants and farm waste management.

• Key Steps: Raw waste mixing + inoculants $\rightarrow$ High-temperature composting (Trough or Crawler compost turner) $\rightarrow$ Secondary curing $\rightarrow$ Semi-wet crushing $\rightarrow$ Trommel screening $\rightarrow$ Automatic bagging.

• Key Advantages: Low initial capital investment, simple operation, and maximum retention of beneficial organic matter and microbes.

2. Granular Organic Fertilizer Line (High Value & Easy Transport)

• Ideal For: Commercial fertilizer manufacturers and bio-organic fertilizer producers.

• Key Steps: Composted powdered substrate $\rightarrow$ Automated batching $\rightarrow$ Wet-type / Rotary drum granulation $\rightarrow$ Rotary dryer (moisture reduction) $\rightarrow$ Counter-current cooler (granule hardening) $\rightarrow$ Screening $\rightarrow$ Bio-agent coating $\rightarrow$ Automated bagging.

• Key Advantages: Uniform particle size, dust-free application, high crush strength, and premium market pricing.

II. Essential Machinery Breakdown

A high-efficiency organic fertilizer production line integrates robust, specialized fertilizer production equipment:

• Composting & Turning Equipment: Trough-type or wheel-type compost turners elevate compost bed temperatures to 55–65°C to eliminate pathogens, weed seeds, and pest eggs.

• Crushing & Blending Units: High-efficiency semi-wet material crushers eliminate clogging from moist compost, while horizontal double-shaft mixers maintain formulation consistency.

• Granulation Systems: New-type organic fertilizer wet granulators or rotary drum granulators deliver sphere formation rates exceeding 90%.

• Drying, Cooling & Screening: Heavy-duty rotary drum dryers and counter-current coolers reduce moisture content below 15% while locking in granule durability.
