Product introduction
The granulation rate of the rotary drum granulator is 70%, the average granulation strength is >10N, the product has uniform nutrition and strong adaptability. Steam is introduced from the machine, phosphoric acid or ammonia solution, slurry, etc. can also be added, and the process is completed in the cylinder. The compound fertilizer production process of chemical reaction; it can also be used in the compound fertilizer production process of supplementing water and humidification
The material enters the front end of the rotating cylinder from the feed port, and the steam inlet pipe at the front end of the cylinder sprays out a certain pressure of water vapor. Since the nozzle of the steam inlet pipe is located at the bottom of the material, and there is a certain pressure when the steam is sprayed out, the material can evenly obtain some moisture and form smaller particles. Due to the inclination of the cylinder, these small particles are constantly moving in the direction of the circumference and axis of the cylinder under the action of gravity and friction of the liner, and the small particles gradually form large particles of a certain size during the movement.
Drum granulator features:
1. It adopts a new granulation process integrating rotation, spheroidization, polishing, densification, heating, drying and other functions.
2. The spiral rotary mechanism is made of high-strength alloy material, which is durable and prolongs the life of the equipment.
3. The material moisture content can be granulated between 30% and 40%, and the output moisture content is about 30%, which reduces the drying requirements of the traditional 70% moisture content process and effectively reduces the production cost of organic fertilizers.
4. During the granulation process, a temperature of 50-65 degrees is generated in the cylinder, which reduces the moisture content of the discharged granules by 5-8 points, thereby reducing the drying cost requirements.
5. The granulation particles are uniform, smooth, round and high in strength, and the granulation rate is over 95%.
6. By adjusting the water content of the feed, the size of the discharge particles can be adjusted to meet the requirements of different particle sizes.
The fineness of the feed material can be granulated when the fineness of the feed material is controlled at about 20 mesh, which improves the crushing process requirements of the traditional granulation at least 80 mesh.
