Best Granulator for Compound Fertilizer Pellets Production
The rotary drum granulator (roller granulator) is one of the key equipment in the compound fertilizer industry, which is suitable for cold and hot granulation and the large-scale production of high, medium and low-concentration compound fertilizers. The barrel 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, wear resistance, low energy consumption, long service life, and convenient operation and maintenance.
How does the rotary drum granulation machine form fertilizer pellets?
The belt and pulley are driven by the main motor, and they are transmitted to the driving shaft through a reducer. The split gear mounted on the driving shaft meshes with the large gear ring fixed on the body to work in opposite directions, and the material is added from the feeding end. Through the inside of the cylinder and the special structure inside the cylinder, it is made into pellets, and then flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, mass production can be realized.
The rotary drum granulator is filled with steam, gas ammonia or phosphoric acid or nitrogen solution, phosphorous ammonia slurry, heavy calcium slurry, and the compound fertilizer granulation process of chemical reaction and heating is completed in the drum; or supplemented cold granulation process of compound fertilizer with small amount of water. The material to be granulated is passed through the rotating movement of the cylinder, and the cylinder is rotated when there is no material, and it is agglomerated into balls under a certain humidity and temperature to complete the ball making process.
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.
