Brief introduction of the process of producing sludge bio-organic fertilizer by disc granulation process:

1. Transfer the treated sludge (living sludge, industrial sludge, etc.), appropriate amount of qualified raw materials such as nitrogen, phosphorus, potassium, and filler to the raw material mixer and mix them evenly.

2. Transfer to the disc homogenizer and add the uniformly mixed material to the rotating disc of the disc granulator by intermittent rotation of the disc.

3. The treated microbial strain is sprayed on the material in the disc through the liquid component distributor of the disc granulator, so that each particle is coated with the microbial strain from the inside to the outside; the rotating circle The disc and the disc edge produce friction and centrifugal action on the material, so that the material produces circumferential movement, so that the powder particles are mutually smashed and squeezed, and gradually agglomerate into a ball; due to the difference in particle quality, the generated gravity and centrifugal effect are also Not the same, when gravity and centrifugation increase enough to overcome the friction between the particles, they are thrown out of the disk, and the smaller particles remain in the disk and continue to collect fine particles.

4. Transfer to the biological fertilizer dryer, and use the large air volume produced by the fan and the low temperature after the sprayed air blower to complete the initial drying of the fertilizer. Due to the species, the drying temperature is strictly controlled below the temperature at which the species survives.

5. Transfer to the hot sieving to sort the granules, and the fine granules directly return to the disc averifier, as the core continues to participate in the adhesion of the granules into spheres.

6. Transfer to the secondary biological fertilizer dryer, fully utilize the high air volume and trace heat to thoroughly dry the bacterial fertilizer.

7. Transfer to the organic fertilizer cooler to cool the fertilizer by natural cold air or strong cooling air.

8. Transfer to the finished screening machine. The large particles are crushed by the crusher and returned to the disc homogenizer to continue to participate in the ball.

9. A small amount of microbial bacteria is lost on the surface of the granules of the bio-fertilizer that has passed through the dryer, and the microbial species on the surface of the granules are replenished by means of a coating machine.

10. Transfer to the fully automatic packaging scale for weighing, packaging and storage.

11. Drying, cooling and workshop dust are emptied by cyclone dust collector, labyrinth dust chamber and wet scrubbing.

 

The production of sludge bio-organic fertilizer by the disc granulation process has the following advantages:

         The operation is intuitive, and the operation of the equipment can be grasped 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. 70%~90%.

The sludge bio-organic fertilizer disc granulation process has short production process, simple structure, low investment and easy operation, and is suitable for small and medium-sized enterprises.
