1. Transport the fermented cow dung powder materials into the raw material mixers directly.
2. Put the mixed materials to the disc feeding machines and uniformly added to the rotating disc of the disc granulators; the liquid component or the appropriate amount of water is sprayed through the liquid component distributor of the disc granulator into the material in the disc, to meet the moisture content required for the ball; the rotating disc and the edge of the disc produce friction and centrifugal action on granulating materials into pellets. Due to the difference in particle quality, the resulting gravity and centrifugation are also different, when the gravity and centrifugation increase enough to overcome the friction between the particles, it will be thrown out of the disk, The smaller particles remain trapped in the disc and continue to condense fine particles.
3. Transfer the granulated pellets to the organic fertilizer dryer for heat exchange with the hot air stove.
4. Transfer to the organic fertilizer cooler to cool the fertilizer through natural cold air or strong cooling air.
5. Transfer to the finished pellets screening machine. The large particles are crushed by the crusher and returned to the disc homogenizer to continue to participate in the ball.
6. The qualified products after screening are transported to the coating machine for coating.
7. Transport to the automatic packaging scale weighing, packaging, storage.
The use of disc granulation to produce cow dung organic fertilizer has the following advantages
The operation of the equipment is easy, you can control it at any time. If it is found to be abnormal, it can be adjusted in time.
The size of the particles is determined by the inclination and rotation speed of the disc, and the inclination and rotation speed of the disc can be adjusted. Therefore, the disc granulation process has a wide control range of particle size, strong adaptability, and a very high sphericity rate, as high as 93%.
Tongda cow dung organic fertilizer disc granulation process has short production process, simple structure, low investment and easy operation, and it is suitable for small and medium-sized enterprises.
