Steps of Making Organic Fertilizer Pellets
1. Raw material mixing: the main material is animal manure, the ingredients (straw, waste tobacco, planting and processing waste, etc.) are crushed, organic biological fertilizer is added, and the nutrient and carbon nitrogen ratio, carbon phosphorus ratio and pH value of the material are adjusted. After treatment, the moisture content of raw material is controlled at 60% - 65%, and the C / N ratio is 20-30. 2. Fermentation: aerobic fermentation process is adopted for organic fertilizer raw material fermentation , tank fermentation overturning machine and paddles (rotary tooth type, positive and reverse rotation) are used to cut and toss materials. The organic materials can be moved backward when overturning, about 2.2 meters are moved backward every time. The tipping machine has the mixing function and can be used as a mixer. The layered materials can be mixed evenly before entering the fermentation area (In this way, the investment of raw material premixing equipment and the wor...
