Poultry manure organic fertilizer disc granulation process

 Disc granulator is mainly used in the granulation of organic fertilizer production line and NPK fertilizer production line. It is also suitable for equipment in chemical industry, medicine, metallurgy, building materials and feed industry. It has the characteristics of compact structure, firmness, convenient installation and stability, and stable performance. The machine is mainly composed of an angled disc and a base, and the inclination angle thereof is adjustable. During the granulation process, the mixed materials of the mixer are transported to the top of the disc by the conveyor, and the disc is continuously and quantitatively added. Inside, the material in the disc is adhered by the adhesive under spray and wrapped into pellets. As the disc rotates, the particles gradually grow. Due to the remarkable grading ability of the machine, large particles float above and continuously flow from below the disc, while small particles continue to grow with the newly added material. The machine has the characteristics of uniform granulation, less grain return and large production capacity.

The poultry manure organic fertilizer disc granulation process has short production process, simple structure, low investment and easy operation. It is suitable for small and medium-sized enterprises; the size of organic fertilizer particles is determined by the inclination and rotation speed of the disc, and the tilt rate and the rotational speed of the disc can be adjusted.Therefore, the disc granulation process has a wide control range of particle size, strong adaptability, and the ball formation rate is very high, which can reach 70%~90%; the operation is intuitive and can be mastered at any time.The operation of the equipment can be adjusted in time if it is found to be abnormal.

Introduction to the process of the granulation mechanism of the disc granulation:
1. The treated poultry manure is directly transported to the raw material silo (or raw material blender);
2. The poultry manure is transported to the disc homogenizer and uniformly added to the rotating disc of the disc granulator; the liquid component or the appropriate amount of water is dripped through the liquid component distributor of the disc granulator to sprinkle on the material in the disc to meet the amount of liquid required for the ball; the rotating disc and the edge of the disc produce friction and centrifugal action on the material, causing the material to move circumferentially, causing the particles to lick each other. And squeezing, gradually agglomerating into a ball; due to the difference in particle quality, the resulting gravity and centrifugation are also different, and when the gravity and centrifugation are increased enough to overcome the friction between the particles, they are thrown out of the disk. Smaller particles remain in the disc and continue to condense fine particles;
3. Transfer to the organic fertilizer dryer for heat exchange with heat from the hot air stove;
4. Transfer to the organic fertilizer cooler to cool the fertilizer by natural cold air or strong cooling air;
5. Delivered 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;
6. Transport to the automatic packaging scale weighing, packaging, storage;
7. Drying, cooling and workshop dust are emptied by cyclone dust collector, labyrinth dust chamber and wet scrubbing.
