The core materials suitable for the organic fertilizer flat die pellet machine are high-fiber, high-moisture organic raw materials, especially suitable for processing materials that are difficult to agglomerate or require uniform granule formation. These can be divided into three main categories, covering the production scenarios of mainstream organic fertilizer produciton lines:
1. Core basic organic materials (best suitability)
• Livestock and poultry manure: chicken manure, cow manure, sheep manure, pig manure (requires pre-treatment to a moisture content of 50%-60%, better after fermentation and maturation)
• Straws: corn stalks, wheat stalks, rice stalks (requires crushing to 20-40 mesh, mixed with manure to adjust cohesiveness)
• Residues: distiller's grains, beer lees, vinegar lees, soybean residue, pharmaceutical residue (moisture content controlled at 55%-65%, can be directly granulated)
2. Auxiliary filling/nutritional materials (need to be mixed with basic materials)
• Oilseed cakes: soybean cake, peanut cake, cottonseed cake (10%-30% after crushing, improves granule nutrients)
• Organic waste: kitchen waste (fermented and matured, impurities removed), sawdust (adjusts humidity and porosity)
• Functional materials: humic acid, amino acid residue (5%-15%, needs to be thoroughly mixed with basic materials to avoid clumping)
3. Unsuitable/materials requiring special treatment
• Pure dry powder materials: such as unfermented dry chicken manure, pure humic acid powder (requires additional water spraying to adjust humidity to over 50%)
• High-viscosity materials: such as pure sludge, sugar residue (requires adding coarse fiber materials such as straw powder and sawdust to reduce viscosity)
• Large uncrushed materials: any raw materials with a particle size exceeding 1cm (must be processed by a crusher to below 40 mesh first)
