Chain type composting machine is a mechanical equipment used for aerobic fermentation treatment of organic waste (such as livestock manure, crop straw, organic waste, etc.), specially designed for large-scale composting sites or organic fertilizer production factories. It uses a chain structure flipping device to efficiently flip and mix compost materials, accelerate the decomposition and transformation of organic materials, promote microbial activity, and is widely used in agricultural waste treatment, organic fertilizer production, bioenergy and other fields.
