The Main Technical Key of the Compound Fertilizer Disc Granulator to Operate the Granulator
Control the water content of granulated particles
- According to the characteristics of the powder: composition, fineness, viscosity, humidity, temperature, etc., the moisture content of the particles should be controlled at about 30-28%.
- Too little water content, difficult to ball, and low output.
- Too much water content, too many big balls, the ball surface is sticky, easy to block the screen surface.
- The water content is appropriate, the pellets are many, and the output is high.
- How to preliminarily check the amount of water in the pellets during the disc granulation production process: a simple and practical method-hand feel method: hand grab a handful of balled materials from the disc granulator, hold it to form a ball, and lightly touch it with your fingers It can be loosened. There are many granules made in this way, the output is high, and the screen surface is not easily blocked.
Strictly control the quality of powder
- Carefully check the quality of various raw materials such as chemical fertilizers according to the formula of compound fertilizer.
- It is strictly forbidden to have iron blocks, stone blocks larger than 10mm, and wooden blocks larger than 10mm when raw materials are discharged and fed. Rice bran and sand are not enough quality indicators, too, which seriously results in low yields.
Three, the main technical key to operating the granulator
- The particle size of the powder used for compound fertilizer is 70-90 mesh.
- Do a good job in technical training for employees to improve their technical quality and operational skills.
Fourth, choose a good nozzle and adjust the nozzle.
According to fluid mechanics, it has been proved that the greater the pressure when the liquid is ejected from the nozzle, the smaller the through hole, and the larger the droplet diffusion surface. Under the same pressure, the nozzle hole is small and the droplet density is small. The spray hole is large and the fog drop density is high.
- The smaller (or larger) the droplets of the feed liquid are, the smaller (or larger) the particle size will be, and the lower (or higher) the output will be.
- The denser (or thinner) the droplets of the feed liquid, the more (or less) the number of feedstocks, the higher (or lower) the output.
- How to choose the model and specifications of the nozzle?
The granulator generally chooses B-type spherical spiral or B1 embryonic spiral nozzle.
Five, use and characteristics
The angle of the pelletizing disc adopts an overall arc structure, and the granulation rate is high. The pelletizing tray is equipped with three discharge ports, which is convenient for intermittent production operations and greatly reduces labor efficiency. The reducer and the motor are driven by a flexible belt, which can start smoothly, reduce the impact force of the buffer, and increase the service life of the equipment. The bottom of the pelletizing disc is reinforced with multiple radiant steel plates, which is strong and durable without deformation. The thickened, heavier, and sturdy base design does not require anchor bolts to fix, and it runs smoothly. The main gear of the granulator adopts high frequency quenching, and the service life is doubled. The granulation face plate is lined with high-strength fiberglass, which is anti-corrosive and durable. It has the advantages of uniform granulation, high granulation rate, stable operation, sturdy and durable equipment, and long service life. The pan granulator is an ideal granulation equipment for users to choose.
