Common types of granulation machinery

There are many types of granulation machinery, and the following are some common types:
Ring die granulator:
Ring die granulator has the highest granulation density, and the granules will not fall apart during the sales and transportation process. However, this granulator must be added with a rounding machine in the later stage to achieve the finished round granules, and its granulation process is more expensive. It is used in some productions that require high granule density and stability. For example, in the production of some high-quality feed pellets, the ring die granulator can ensure that the feed pellets are not easy to break during storage and transportation, maintain good pellet integrity, and facilitate the preservation and feeding of feed.

Gear stirring organic fertilizer granulator:
This is a product that is widely favored by customers and is hot in the market. The pellets it produces are smooth and have high process output. If an organic fertilizer rounding machine is added, the granulation effect can be comparable to disc granulation. However, this granulator needs to purchase a cooler and a dryer, so the whole set of equipment is more expensive. In the field of organic fertilizer production, the gear stirring organic fertilizer granulator can efficiently make organic materials into pellets, improve the production efficiency and product quality of organic fertilizers, and meet the market demand for organic fertilizers.

Disc granulator:
Disc granulator is a more traditional granulation process equipment, with low price, good-looking and smooth granules, but low density. Although people are more pursuing new granulation methods, disc granulators are still used in some small fertilizer production plants or production that is more sensitive to cost. For example, in some small family-style organic fertilizer production workshops, the low cost and simple operation of the disc granulator make it a suitable choice. It can mix various organic materials to make granular organic fertilizer.

Drum granulator:
Drum granulator is a process that has been used for compound fertilizer granulation. The granulation rate is low, but it can also be used to produce organic fertilizer, especially when producing organic-inorganic compound fertilizer. This process can be selected. It rolls and rotates in the cylinder through the rotation of the cylinder, and makes the material stick into balls at a certain humidity and temperature. During the movement, the smaller particles gradually form particles of a certain specification to complete the granulation process. In compound fertilizer production enterprises, the drum granulator can mix various fertilizer raw materials into compound fertilizer particles according to different formulas. It is one of the important equipment in compound fertilizer production.

Double-roller extrusion granulator:
It belongs to dry granulation, does not require drying process, has good fertilizer efficiency, high granulation density, and full organic matter content. There is no need to burn coal in the later stage, and the cost of purchasing coolers and dryers is saved, saving a lot of money. However, it is easy to jam the machine when sowing field crops by machine. The shape of the granules produced by the extrusion granulator is oblate and the fluidity is not very good. Therefore, if the organic fertilizer is made for farmers who sow by machine, this granulation process should be used with caution. It is recommended to use it for compound fertilizer and compound fertilizer. In the production of compound fertilizer and compound fertilizer, the double-roller extrusion granulator can effectively extrude dry powder fertilizer raw materials into granules, reducing energy consumption and equipment investment in the production process.

CF type rotary belt condensation granulator:
This granulator uses a rotary belt structure to shape the material by condensation. It is suitable for some materials that are easy to shape under specific temperature conditions, such as the granulation of some heat-sensitive materials. In the chemical industry, for some temperature-sensitive chemicals, the CF type rotary belt condensing granulator can complete the granulation process at a lower temperature to avoid the material from deteriorating or losing activity due to high temperature.

Flat twin-screw extruder:
During the granulation process of the flat twin-screw extruder, the rotation of the twin screws mixes, conveys and extrude the materials. The design and speed of the screws and other parameters can be adjusted according to different materials and production requirements. This granulator is widely used in the plastic processing industry. It can process plastic raw materials into plastic particles of various shapes and specifications. It can be used to produce raw material particles for ordinary plastic products, and can also be used to produce plastic particles for special purposes such as engineering plastics.

Drum drying tablet making machine:
The drum drying tablet making machine combines the functions of drying and tablet making (granulation). In the processing of some materials, the material is first dried and gradually formed into flakes or granules by rotating the drum. In the pharmaceutical industry, for some drug raw materials containing water, the drum drying tablet making machine can make them into suitable granules or tablets while drying the raw materials, improving production efficiency and product quality.

Roller dry granulator:
The working principle is that various dry powder materials are added from the top of the equipment, degassed and spiral pre-pressed into the rollers, and the materials are plastically deformed and compressed into flakes under the great extrusion force of the rollers. The flake materials are then crushed, granulated, screened, and other processes to obtain granular products. The size of the extrusion force can be adjusted by the pressure of the hydraulic cylinder according to the needs of the granulation operation. In the chemical, building materials and other industries, the roller dry granulator can be used to make dry powder materials into granules, such as making powdered chemical raw materials into granular products that are easy to store and transport.

Gear granulator:
The gear granulator uses a special gear structure to process the material to form granules. It has unique advantages in the granulation of some special materials. For example, when granulating some materials with high viscosity, the gear structure can effectively cut, mix and extrude the material to form uniform granules. In the food industry, for some food raw materials with high viscosity such as jam raw materials, the gear granulator can play a better granulation effect.
