Rotary drum fertilizer production line, in which steam, gas ammonia or phosphoric acid or nitrogen solution, phosphoric ammonia slurry, heavy calcium slurry are added to the machine to complete the chemical reaction and heat supply compound fertilizer granulation process; or The cold granulation process of compound fertilizer supplemented with a small amount of water. The material to be granulated is passed through the rotation of the barrel, and the barrel rotates when there is no material. Under the appropriate humidity and temperature, the ball will be aggregated to complete the ball making process.
Features of drum fertilizer production line:
1. The ball formation rate is up to 70%, there is a small amount of returned material, the particle size of the returned material is small, and it can be re-granulated;
2. Steam heating is introduced to increase the temperature of the material, so that the moisture of the material is low after the ball is formed, and the drying efficiency is improved;
3. Use rubber engineering plastics as the inner lining, the raw materials are not easy to stick to the cylinder, and have the effect of anti-corrosion and heat preservation;
4. Large output, low power consumption and low maintenance cost.
