Disc granulator is a kind of equipment that compresses powdery or granular materials into fixed shape granules by rotating disc. Its core working principle is to use the rotating disc to generate centrifugal force, so that the material on the surface of the disc to form a certain thickness, and through the disc edge of the shear force and extrusion pressure to press the material into particles

1. Adjustment section: This is the most important part of the whole machine, in which the granulating plate is the key component of the whole center of gravity. The installation and adjustment of the pelletizing plate are all done in this part. 2.
2. frame part: the frame is the supporting part of the whole machine, carrying the whole transmission part and rotating working part. Since this part is subjected to large force, it is usually welded with high quality carbon channel steel to ensure its strength and stability.
3. Transmission section: The transmission section is the core part of the Disc granulator and is responsible for driving the whole machine. Key components such as electric motor and reducer are installed in this part, through the transmission mechanism to transfer the power to the disc to make it rotate for granulation.
4. Automatic material cleaning part: this part is usually installed above the pelletizing tray, shaped as a lower frame and equipped with an automatic cleaning plate. Its main function is to remove the material stuck on the pelletizing tray during the production process, improve the cleanliness of the material, extend the service life of the machine, and save the time and cost of manual cleaning.
5. Pelletizing disc part: Pelletizing disc is the key working part of Disc granulator, which usually adopts the whole curved design to improve the pelletizing efficiency and quality. Parameters such as the angle and speed of the disc granulator can be adjusted through the adjustment section to suit different materials and production needs.
In addition, the Disc granulator may also include auxiliary components such as dosing tubes, material sprayers, hanging plates, etc. to meet specific production process requirements.
1. Raw material feeding: The material to be granulated is added into the hopper of the Disc granulator through the inlet.
2. Hopper lifting: Through the instruction of controller, the hopper starts to lift and move, and bring the material to the edge of the granulating disk gradually.3. Rotating movement: The disc granulator starts to rotate at high speed, generating centrifugal force. The centrifugal force makes the material move outward and distribute evenly on the pelletizing disk.
4. Addition of binder: While the pelletizing disk is rotating, the binder is added to the material through the spraying device. The binder can be water, solution or other binder.
5. Particle formation: the material is subjected to centrifugal force and binder action on the pelletizing disk, and gradually form particles. Impacts and abrasions will occur between the particles, thus making the particles more uniform and firm.
6. Pellet collection: The formed pellets are dislodged from the pelletizing disc and slide down to the pellet collector by gravity. The collector will collect the granules.
7. Dusting: During the pellet sliding process, some fine dust particles may be generated. These particles will be processed through the dust removal system to ensure particle size consistency and product quality.
8. Recycling: After the dust particles are treated by the dust collector, they can be recycled and put into the raw material for granulation again. Through the above working principle, Disc granulator can make the powder or granular raw materials into various sizes, shapes and densities of granules, which are widely used in the process of granule preparation in chemical, agricultural, pharmaceutical and other industries.
1. High efficiency: Disc granulator has high efficient granulation capacity, which can quickly convert a large amount of material into granules of desired shape.
2. Good granulation quality: Through the shear force and extrusion force at the edge of the disc, the Disc granulator is able to produce tightly packed and uniformly shaped granules, which improves the stability and ease of use of the product.
3. Wide range of application: Disc granulator is suitable for granulation of many kinds of materials, such as fertilizers, pesticides, feed, etc., with strong versatility.
4. Simple operation: Disc granulator’s structure is relatively simple, easy to operate and low maintenance cost.
1. Higher energy consumption: Due to the need to drive the disc to rotate at high speed, the energy consumption of Disc granulator is relatively high, which is not conducive to energy saving and environmental protection.
2. Difficulty in adjusting the particle size: the size of the particles is mainly affected by the rotational speed of the disc, the nature of the material and the amount of water added, and adjusting these parameters to obtain the desired particle size may require some experience and skill.
3. Noise and dust pollution: In the process of granulation, the high-speed rotation of the disc may generate a large noise and a certain amount of dust pollution, which requires appropriate measures to control and manage.
1. Reasonable structure, new design, weight reduction, height reduction, flexible and convenient process arrangement, suitable for old plant renovation.
2. the inclination angle of the large disk can be adjusted, and the adjustment becomes flexible and convenient by adopting angle shims.
3. the unique powerless combination of scraper integration, so that the auxiliary power consumption is reduced.
4. The big disk is composed of disk body and disk section, and the disk section can be adjusted up and down along the disk body to reduce the power of the main motor. The end of the disk section is a side flange, to ensure that the material ball out of the disk will not be strained or torn.
5. It has a new design of silt removal, through the combination of scraper without power to clear the edge and bottom, as well as the corner scraper to clear the corner of the disk, with the unique processing technology of the disk body, silt removal, ball formation effect is good, there will be no big mud, 90% of the diameter of the ball is within the range of 3\~5mm.
6, increase the spraying device, improve the granulation rate, reduce dust pollution.
Disc granulator machine and double roller granulator are two common granulation equipment, their main difference lies in the working principle and scope of application.
1. working principle: disc granulator mainly through the rotating disc will be rolling and compression of raw materials, so as to form particles. While double roller granulator is to use the extrusion between the two relative rotating rollers, the raw material will be compressed into granules.
2. Scope of application: disc granulator is suitable for the manufacture of lower density, strength requirements are not high particles, such as certain fertilizers, feed and so on. And double roller granulator is suitable for manufacturing high-density, high-intensity particles, such as some special fertilizer, feed and organic granulation.
