Granular biofertilizers are popular with customers because of their ease of storage and application. Bio fertilizer granulator is an important equipment for making biofertilizer in granule form. For high-quality biofertilizers manufacturing, you can prepare from three aspects: raw material preparation, granulation process selection, and drying and cooling biofertilizer pellets.
Top 3 pelletizer machine used to make biofertilizer in granular form:
To make biofertilizer in granular form, you can choose to use different biofertilizer granulators with unique granulation methods. The following are three hot-selling granulation equipment:
The disk granulator
The disk pelletizer adopts wet granulation, which makes biofertilizer particles through the rotation of the disk and the action of gravity.
The roller extrusion granulator
The roller extrusion granulation equipment adopts dry granulation. Extrusion of two rollers to form uniform size particles.
The drum granulator
In addition, the drum granulator is also the wet granulation of aggregates. It is by means of the rotating movement of the cylinder to produce extrusion pressure between the materials and aggregate into balls.
How to make high-quality bio fertilizer pellets ?
Maintain the moisture content of the raw materials at around 30% to prevent excessive moisture from causing mold sticking and clogging of the biofertilizer granulation equipment.
Select the appropriate biofertilizer granulation method according to the material characteristics. Such as disc granulation, drum granulation, roller extrusion pelleting, etc. In the granulation process, strictly control the process parameters to ensure uniform shape and consistent size.
You need to dry the bio fertilizer pellets after granulation. It is beneficial to reduce the moisture content and prevents excessive microbial growth or granule mildew during storage. The dried granules should be cooled in time for subsequent packaging and storage.
Can I customize the bio fertilizer pellet shape and size?
Of course. Usually, drum granulators and disc pelletizers can produce round bio fertilizer granules. With roller extrusion granulation, you can customize a variety of granule shapes such as cylindrical, spherical, and flake. The principle is to engrave precisely designed grooves on the surface of the roller. The shape, size, and arrangement of these grooves can be customized according to your requirements. You can get the ideal size (2-10 mm) biofertilizer pellets with YUSHUNXIN’s granules making machine.
