What are the operating techniques of compost turning machine during composting?

A compost turning machine is a must-have for efficient composting, helping materials decompose faster and more evenly. The following are some tips on how to operate the compost turnig machine during the composting process:

1. Preprocessing Tips

Control the chunk size: Big chunks slow things down. Before piling up, shred or chop bulky stuff like branches to about 2-4 inches (5-10 cm). Anything bigger makes it hard for the machine to mix properly.

Humidity Control: Proper humidity is the key to successful composting. If the material is too dry, microbial activity will slow down. If it is too wet, an anaerobic environment will easily occur. Aim for a damp sponge feel—around 50-60% moisture. If it’s too dry, sprinkle water. If it’s too wet. Mix in dry straw or sawdust.

2.Operation Tips

Dig deep enough: Don’t just skim the surface. The machine should reach about two-thirds of the pile’s height to mix the top and bottom layers properly. This keeps oxygen flowing and prevents dead spots.  

Speed control: The compost turning machine should be operated at a moderate speed. If the speed is too fast, the material will be turned unevenly. If the speed is too slow, the work efficiency will be reduced. According to the type and quantity of compost material, the speed of the compost turning machine should be adjusted reasonably.  

3. Monitoring Tips

Check the temperature: Use a compost thermometer. A healthy pile heats up (to 50-70°C), but if it goes above 70°C, it can kill helpful microbes. Turn more often to cool it down.  

Smell judgment: Good compost smells earthy. If it stinks (rotten eggs or ammonia), it’s likely too wet or not getting enough air. Fix it fast by turning more or adding dry, bulky material.

By mastering the operating skills of these compost turning machines, the quality and efficiency of composting can be effectively improved, thereby providing high-quality organic fertilizer for agricultural production.
