Pig manure has a high moisture content and is very sticky, making it prone to clumping, anaerobic digestion, and foul odors. Windrow compost turning machines, with their strong grip and resistance to material slumping, are the preferred equipment for pig manure windrow composting.
Pre-treatment and equipment inspection are fundamental. Pig manure should not be turned directly; it needs to be mixed with dry straw and sawdust to adjust the moisture content. Remove stones, plastic bags, and other hard objects to prevent them from sticking to the tracks and damaging the turning teeth. Before operation, check the track tension and the tightness of the turning components. Conduct a no-load test run to check for abnormal noises and slippage.
Strict attention to detail is crucial during operation. The pile size should be compatible with the tracked compost turning machine parameters. Maintain a constant speed and straight line movement; sharp turns and sudden acceleration are strictly prohibited to prevent track slippage and pile collapse. The turning depth should be moderate, breaking up clumps, providing oxygen and heat dissipation, without touching hard objects to protect the tracks and turning teeth.
Fermentation control cannot be relaxed. During the high-temperature fermentation period, the compost pile should be turned regularly to ensure even oxygenation and heat dissipation, preventing anaerobic fermentation, foul odors, and maggot breeding. After turning, the pile should be neatly arranged to ensure ventilation, accelerate decomposition, and prevent root burn from uncooked pig manure.
Post-operation maintenance and safety are crucial. Promptly clean any pig manure residue from the tracks and turning teeth to prevent it from drying and corroding the equipment. Operators should stay away from moving parts and strictly prohibit any improper operation. Mastering these points will not only ensure efficient decomposition of pig manure but also extend the service life of the self-propelled compost turning machine.
