Windrow compost turning machines are central to modern composting. Their efficiency is closely tied to the material’s characteristics. Knowing exactly what these machines need from the compost mix is key to optimizing fermentation and getting high-quality compost.

Physical Requirements
1.Material Size Control
Ideal Range: Crushed pieces between 20-50mm.
Too Large: Hinders the turner tines from grabbing material, reducing turning efficiency.
Too Fine: Easily compacts, hurting airflow.
2.Moisture Content Control
Best Range: 50-65%.
Too High: Makes material sticky and clumpy, creating anaerobic conditions.
Too Low: Slows fermentation due to low microbial activity.

Chemical Requirements
1.Carbon-to-Nitrogen (C/N) Balance
Ideal Ratio: 25:1 to 30:1.
How to Adjust: Mix high-carbon materials (like straw) with nitrogen sources (like livestock manure) scientifically.

2.pH Range
Suitable Range: 6.5-8.5.
Adjustment Tip: Use plant ash or sulfur powder to manage acidity/alkalinity.

Material Mixing and Pre-Treatment Requirements
1.Mixing Principle
Structure Adjustment: 70% wet material + 30% dry material.
Example Mix: 60% livestock manure + 40% straw.
2.Pre-Treatment Needs
Crushing: Break down large chunks beforehand.
Thorough Mixing: Ensure raw materials are blended evenly.
Moisture Adjustment: Use additives or returned compost to get the right moisture level.

Understanding these requirements for windrow compost turning machines compost material is the foundation for efficient composting. By using the right mix, proper pre-treatment, and smart operation settings, you can get the most out of your windrow compost turning machine.
