Chain plate type compost turner is suitable for aerobic composting of organic solid waste, such as livestock and poultry manure, sludge and garbage, and straw and so on. Its walking system adopts frequency conversion speed regulation, so it has the characteristics of good adaptability to different materials, smooth operation, high turnover efficiency and deep groove operation. It can effectively shorten the fermentation period, improve production efficiency and product quality. Variable frequency speed control system can be well adapted to the change of working load. The equipment makes full use of the deep pool design to realize automatic discharge, and large-scale treatment of harmless organic waste has become a reality.
