8t/H 11.5r/Min Corrosion Resistant Rotary Drum Granulator for NPK Compound Fertilizer Production

The drum granulator is one of the key equipment in the organic fertilizer compound fertilizer industry, suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizers. The main working method is wet granulation of agglomerates. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder after the humidity is adjusted. Under a certain liquid phase condition, the rotation of the cylinder is used to produce between the material particles. The squeezing force reunites into a ball.

The cylinder of the machine adopts a special rubber plate lining or acid-resistant stainless steel lining plate, which realizes automatic scar removal and tumor removal, eliminating the traditional scraper device. The machine has the characteristics of high ball strength, good appearance quality, corrosion resistance, abrasion resistance, low energy consumption, long service life, convenient operation and maintenance.

• Balling rate is more than 90%, with small amount of return material and small feed back size that can be re-granulated
• Steam heating improves material temperature, resulting in lower water content after ball forming and improved drying efficiency
• Rubber engineering plastics lining prevents material sticking and provides anti-corrosion and insulation properties
• Large capacity with low power consumption and maintenance costs

Livestock and poultry manure and urine, compost fertilizer, green manure, sea fertilizer, cake fertilizer, grass charcoal, soil and miscellaneous fertilizer, three wastes, microorganisms

• High ball formation rate with minimal returned material; returned material has small particle size and can be re-granulated
• Steam heating increases material temperature, resulting in low moisture content after ball formation and improved drying efficiency
• Rubber engineering plastics lining prevents raw materials from sticking to the cylinder and provides anti-corrosion and heat preservation
• Large output capacity with low power consumption and maintenance costs
