MFP - Pan Granulator for Fertilizer Production
The pan granulator, also known as a disc granulator or disc pelletizer, is an essential device in the manufacturing of various fertilizers, including compound, organic, and inorganic fertilizers. Its design incorporates an arc structure yielding a high granulation rate exceeding 93%, making it a highly efficient option in fertilizer production. The device features three outlets for simplified intermittent production, reducing labor intensity. The pan granulator works by mixing raw materials with water, enabling the creation of spherical granules through centrifugal force and gravity. The disc's adjustable angle influences granule size, while the rotary speed affects the balling rate. The machine's sturdy design, including a welded base, eliminates the need for ground mounting and ensures smooth operation. Featuring components like a main reduction gear and a motor-driven power unit, it is designed for optimal power efficiency, thus enhancing operational productivity.
in a discgranulator. the balled materials are continuously discharged from the disk and new materials are added into the feeding tray, repeating the process until the powdery materials become spherical products.
The particles form spherical particles by agglomeration, and as they increase in size, they move up to the circular disc in rotation. Finally they roll to the edge. The small particles initially roll near the bottom edge of the circular disc.
During the rolling granulation process, due to the influence of gravity, the spherical particles make circular motion.
Klatfs experiments in 1958 showed that the finer the solid, the more uniform the liquid that is sprinkled in, the better the granulation. The smaller the droplets of material, the smaller the diameter of the granules, and the lower yield. Conversely, the denser the droplets, the more granules, and the higher the yield. Besides, the feed rate can control the granulation temperature.
A good pan granulator should be a high-quality design, because each part of disc granulators will influence its effect. Therefore, when you choose a pan granulator, you'd better take the following factors into consideration.
- The main body of it includes the frame, the adjustment part and the granulation disc. These three parts consists of a compact structural design.
- One main reduction gear. This gear can decrease the velocity of input from the motor. For pan granulators, velocity is a key factor to make uniform granules. By this gear, you can control the speed of disc pelletizers to improve your granulation efficiency.
- One motor power, equipped with one pulley, our power made from a famous company. It Is power-efficiency and can save your power to the maximum.
- Disc granulator supporting device, including one main shaft, two sets of roller bearings, and two bearing seats. Because the whole structure is supported by the supporting device, plus the weight of raw materials when working, the supporting device of the machine is welded with thickened channel steel and meets strict quality certification.
- Design in the granulator pan bottom. The bottom of the disc pelletizer is welded and formed by multiple radiant steel plates, which is durable and not easily deformed. What's more, the material of our pan granulator base design is thick and sturdy. Therefore, you don't have to screw the granulator to the ground, and they can work smoothly.
