The working principle of the disc granulator of the NPK fertilizer production line: the main motor drives the pulley and the belt, and the pinion gear is driven by the reducer. The pinion gear and the large gear fixed at the bottom of the disk mesh with each other, and the large gear works through the special reasonable the design is installed on the main shaft fixed on the frame adjustment plate to support the work of the entire granulation plate (this machine is used in conjunction with the sprayer). After the material enters the granulation plate, it is continuously rotated and sprayed by the granulation plate. , Make the materials evenly stick together to form spherical particles. An automatic cleaning device is designed in the upper part of the granulation plate of the machine to prevent the material from sticking to the wall, thereby greatly improving the service life of the disc granulator. With the motor the continuous rotation of the material and the continuous entry of materials can achieve mass production.
Disc granulator structure of NPK fertilizer production line:
1. Frame part: Since the transmission part and rotating work part of the whole body are supported by the frame and the force is relatively large, the frame part of the machine is welded with high-quality carbon channel steel and has passed strict quality certification and specific technical requirements.
2. Adjustment part: The important part of the whole machine is the pelletizing disc, and the entire center of gravity of the pelletizing disc is installed and adjusted on the part.
3. Transmission part: The transmission part of the whole machine is excellent and important, and the overall work is done. The motor and reducer on the installation and transmission adjustment frame are selected for ISO/9001 quality system certification exempt products, and the quality is reliable. The motor drives the pulley and the V-belt. The reducer and the pinion are driven by the pinion to drive the large gear on the pelletizing disk to make the pelletizing disk work. In addition, the large and small gears are high-frequency quenched, and the service life is twice the original. The pelletizing disc is fixed on the active shaft on the adjusting disc, and the coupling part of the column head adopts a taper fit, and the design is more reasonable;
4. Part of the granulation disc: the angle of the granulation disc of the disc granulator adopts an overall arc design, and the bottom of the granulation disc is reinforced by multiple radiant steel plates, which is durable and never deformed;
5. Automatic cleaning part: This part is installed above the pelletizing tray and has a lower frame shape, with an automatic cleaning board installed on it, so as to remove the materials sticking to the wall during the NPK fertilizer manufacturing process, which greatly improves the service life of the machine, it also saves labor.
