Material suitability for different compost turning machines: Choosing the right equipment for production needs

fertilizer granulator Aug 22, 2025

In organic fertilizer production, the compost turning machine is core equipment for material fermentation. However, different types of turners have specific requirements for material characteristics.

1.Materials Suitable for Windrow Compost Turning Machines

High-density materials: Like livestock manure, sludge, and other sticky substances.

Large-volume compost piles: Handling capacities can exceed 3000 m³/h.

Materials with higher moisture content: Mixed compost with 60%-70% moisture.

With their heavy-duty shredding mechanism, these machines effectively break up clumps. They’re particularly suited for large-scale farms and big organic fertilizer plants.

2.Applications for Trough-Type Turners

Fine composting: Materials needing highly uniform turning.

Materials where microbial inoculants are added: For easier fermentation control.

Municipal solid waste: Complex organic refuse.

Their enclosed design minimizes odor spread, making them ideal for projects near urban areas with strict environmental rules.

3.Material Advantages of Chain Turners

Materials high in fiber: Like straw, garden waste, etc.

Piles needing thorough aeration: Their unique structure boosts oxygen penetration.

Long-term stacked materials: Can handle fermentation piles up to 2 meters deep.

Selecting a compost turning machine boils down to precisely matching material properties with machine functions. Understanding key factors–like the stickiness of livestock manure, the fibrous nature of straw-based materials–is essential for picking the best turning solution.

What materials are suitable for compost turning machines fermentation?

Compost turning machines are key equipment in the composting process. They effectively promote aeration, mixing, and decomposition of the materials, boosting both the speed and quality of composting.

1.Animal Manure

Chicken Manure: High in nitrogen, decomposes quickly. Turners speed up decomposition and reduce ammonia loss.

Cow Manure: Higher fiber content. Turners break up clumps and improve air flow.

Pig Manure: More adhesive; requires mixing with bulking agents (like straw) during turning to prevent compaction.

2.Agricultural Waste

Crop Straw: Corn stalks, wheat straw, rice straw, etc. Turners break down long fibers, speeding up decomposition.

Fruit and Vegetable Scraps: Vegetable leaves, fruit peels, leftover produce. Turners ensure even mixing and prevent anaerobic conditions.

Spent Mushroom Substrate: Waste after mushroom cultivation. Turners promote secondary fermentation into good quality compost.

Bagasse or Peanut Shells: High carbon-to-nitrogen ratio. Turners help balance the compost and increase humus content.

3.Sludge and Organic Solid Waste

Sewage Sludge: Rich in organic matter. Turners help reduce heavy metal activity and promote safe treatment.

Food Waste: High in easily decomposable organics. Turners speed up breakdown and reduce odors.

Yard Waste: Fallen branches, leaves, grass clippings. Compost turning machines shred and promote decomposition.

4.Industrial Organic Waste

Herbal Medicine Residue: Plant-based leftovers. Turners promote breakdown into bio-organic fertilizer.

Textile Waste (Natural Fibers): Degradable cotton or linen waste can be composted for resource recovery.

Compost turning machines work well with many materials. However, the specific properties of each material (moisture, stickiness, C/N ratio) need to match the right turning approach. Choosing the right turner and optimizing the fermentation settings significantly improves composting speed and quality.

Precautions for Using a Compost Turning Machine

As a core piece of equipment for material fermentation in an organic fertilizer production line, the proper use of a compost turning machine directly impacts production safety and fermentation efficiency. During daily operation, equipment inspection and parameter adjustment must be thoroughly monitored to ensure maximum performance.

A thorough pre-startup inspection is the first line of defense for safe operation. Check the tracks or running wheels for deviation and bolt connections for looseness. In particular, check for breakage or excessive wear on the turning blade assembly to prevent blades from falling off and causing damage to the equipment during operation. Also, clear the fermentation tank of hard objects such as rocks and metal to prevent them from becoming entangled in the turning mechanism and causing it to jam. Electrical system inspection is essential. Ensure cables are intact and grounding is reliable. Install a waterproof cover during rainy weather to prevent electrical leakage.

Parameter adjustment during operation is crucial for ensuring fermentation quality. Dynamically adjust the turning depth and frequency based on the material’s characteristics: High-protein materials like fresh livestock and poultry manure require more frequent turning to ensure ventilation and oxygen supply to prevent anaerobic decay. Crude fiber materials like straw can be turned more deeply to promote even mixing. The turning speed should be matched to the material’s moisture content. If the moisture content is too high, slow the turning speed to reduce clumping. Dry materials can be turned faster to improve efficiency.

Post-downtime maintenance determines the lifespan of the equipment.After each run, clean the blades and trough to prevent caking and compaction, which increases the load at the next start-up. Regularly lubricate bearings, chains, and other transmission components, and promptly replace severely worn parts. When the equipment is idle for extended periods, it should be stored in a dry location, the blades should be coated with anti-rust oil, and the electrical system should be disconnected from the power supply and dust-proofed.

Proper operation of a compost turning machine is not only essential for ensuring production safety, but also a scientific approach to improving fermentation efficiency and reducing operational costs, laying a solid foundation for the resource utilization of organic waste.

The “Iron Chef” of Compost: Perfect Fermentation by Compost Turning Machine

fertilizer granulator Aug 12, 2025

On the stage of organic fertilizer production, the compost turning machine acts like a masterful “iron chef”, meticulously controlling each fermentation step to “cook” various organic wastes into nutrient-rich compost. Let’s explore this “chef’s” secret recipe.

Step 1: Meticulous Ingredient Preparation

Like a chef preparing ingredients, raw materials first undergo crushing and screening to remove impurities, achieving the “golden size” of 2-5 cm particles. The carbon-nitrogen ratio (25-30:1) and moisture content (50%-60%) are adjusted—the perfect formula for microbial activity. Too wet? Add straw “absorbent”. Too dry? Add water for “seasoning”.

Step 2: Scientific Layering in Trough

Pre-treated materials are evenly spread in fermentation troughs at 0.8-1.5m depth—this “fermentation bed” thickness ensures sufficient heat generation without compromising ventilation. Like baking a cake in the right pan, this thickness is the “gold standard” from years of practice.

Step 3: Precise Temperature-controlled Turning

When material temperature reaches 60-70°C, the “iron chef” begins work. Its turning teeth act like chef’s spoons, flipping and mixing materials so every part can “breathe”. This phase resembles slow cooking, with turning every 1-3 days over 15-30 days, allowing microbes to fully “cook” the organics.

Step 4: Maturity Assessment and Harvest

When temperature drops to ambient level and materials turn dark brown with earthy fragrance, this “organic feast” is ready. The material becomes loose, odor-free, with pathogens eliminated by heat, ready for further “processing”.

Why Choose This “Iron Chef”?

• High Efficiency: 30%-50% faster than manual methods
• Superior Quality: Even turning ensures perfect “doneness”
• Labor-saving: Automated operation reduces workforce
• Eco-friendly: Minimizes odor and energy consumption
• Versatile: Handles diverse “ingredients” from manure to straw

In the kitchen of circular agriculture, compost turning machines are using their “culinary art” to transform waste into “black gold”, providing continuous nutrition for green farming.
