Disc granulator/fertilizer granulator is suitable for granulating organic fertilizer, compound fertilizer, composite fertilizer, and organic-inorganic compound fertilizer. Due to its high granulation rate, large hourly output, stable operation, durable equipment, and long service life, it is chosen by the majority of users as an ideal granulation equipment.
Working principle of disc granulator
The powder added from the feeding pipe to the inclined disc adheres to the droplets sprayed by the liquid sprayer to form a small particle group. The gravity and centrifugal force generated by the inclined disc during rotation cause the small particle group to continuously roll and adhere to the powder at the lower edge of the disc, causing the particles to continue to grow. At the same time, under the action of the friction force at the bottom of the disc, the particles move upward with the disc.
When they reach the scraper, the granulated powder passes through the gap between the scraper and the disc, and some particles roll to the edge of the disc along the direction of the scraper. They continue to roll and adhere to the powder, and after multiple cycles, they grow from small to large, reaching the range of the finished particles along the edge of the disc. The factors that affect the disc granulation are: the diameter, inclination, side height, rotation speed of the disc, the position of the liquid spraying, and the position of the scraper plate.
Disc granulator composition structure
1. Organic fertilizer disc granulator frame part
Because the transmission part and the rotating part of the whole machine have a large supporting force, this machine adopts the carbon channel steel welding of the frame part, and passes strict quality certification and specific technical requirements to achieve the purpose of the machine.
2. Organic fertilizer disc granulator adjustment part
The important part of the whole organic fertilizer disc granulator is the granulation plate, and the entire important part of the granulation plate is installed on the adjustment part. It is welded with high-quality carbon steel plate and channel steel, and passes strict quality certification. Which fully meets the requirements of the machine.
3. Organic fertilizer disc granulator transmission part
The transmission part of the whole machine is very important, and the whole work has this line. The motor installed on the adjustment frame is of reliable quality. The motor drives the pulley and belt. The reducer and pinion are driven by the pinion, and the large gear on the pellet plate makes the pellet plate work. In addition, gears of different sizes are high-frequency quenched, and their service life is twice that of the original gears. The whole ball-making plate is fixed on the driving shaft of the adjustment plate. And the column head connection part adopts taper matching to make the design more reasonable.
Disc granulator design
4. Organic fertilizer disc granulator granulator disc part
The disc angle of the disc granulator adopts an overall arc design, and the granulation rate can reach more than 93%. The bottom of the granulator disc also adopts a batch of radiation steel plates to strengthen it. Which is strong and durable and not easy to deform.
5. Automatic cleaning part of the organic fertilizer disc granulator
This part is installed on the top of the granulation plate to form a lower frame and is equipped with an automatic material cleaning plate. So as to clean the materials stuck on the plate wall during the production process. Which greatly improves the service life of the machine and saves labor.
Uses and features of pan granulator
The disc granulator adopts an overall arc structure, and the granulation rate can reach more than 95%. The granulation disc is equipped with three discharge ports. Which is convenient for intermittent production operations, greatly reducing labor intensity and improving labor efficiency. The reducer and the motor adopt flexible belt transmission, which starts smoothly, reduces impact force, and increases the service life of the equipment. The bottom of the granulation disc is reinforced with multiple radiation steel plates. Which is sturdy and durable and never deformed. The thickened, heavier, and sturdy base design does not require anchor bolts to fix and runs smoothly. The main gear of the granulator adopts high-frequency quenching, and its service life is increased by 1 times.
The granulator disc is lined with high-strength fiberglass, which is corrosion-resistant and durable. This machine has the characteristics of uniform granulation, high granulation rate, stable operation, sturdy and durable equipment, and long service life. It is an ideal equipment for users.
