The difference between rotary drum granulator and counter roll extrusion granulator

图片
  Both   rotary drum granulators   and roller extrusion granulators have their own advantages in fertilizer production, and they have significant differences in multiple dimensions. In terms of working principle, the  rotary drum granulator  uses a rotating drum to lift up the material internally. Under the action of centrifugal force, friction force, and gravity, the material circulates and the binder is sprayed to form the particles. The counter roll extrusion granulator uses a pair of rotating rollers to squeeze the material into the concave mold on the surface of the rollers, without the need for adhesive (which can be added in some cases). In terms of particle characteristics, the shape of the particles produced by the rotary drum granulator is relatively regular, mostly approximately spherical or elliptical, and the surface of the particles is relatively smooth. Due to the sufficient rolling of the material inside the drum, the internal structure of the pa...

How to choose fertilizer granulator for NPK fertilizer manufacturers

图片
  NPK fertilizer (i.e. nitrogen, phosphorus, potassium compound fertilizer) manufacturers should consider multiple aspects when choosing a   fertilizer granulator   to ensure that the selected equipment can meet production needs while achieving efficient and economical operation. Here are some key selection points: 1. Production objectives and specifications Please specify the type (such as powder or granular), yield, particle size, and shape requirements of the NPK fertilizer you wish to produce. Consider the possibility of future expansion and reserve a certain amount of production capacity surplus. 2. Granulation technology Extrusion granulation: suitable for low humidity materials, easy to operate, widely applicable. Rotating disc granulation: The produced particles are relatively uniform and suitable for large-scale production. Spray granulation: suitable for materials with good solubility and fine particles. Choose the most suitable granulation method based on your ...

How to use a disc granulator to process fertilizers in a fertilizer production line

图片
  In the fertilizer production line, the   disc granulator   is like a skilled "shaper", endowing fertilizers with ideal shapes. After various fertilizer ingredients are mixed according to precise formulas, they enter the  disc granulator . The machine starts and the disc begins to slowly rotate. Under the clever action of centrifugal force, frictional force, and gravity, materials gradually gather at the edge of the disc. At first, these materials were just a loose collection, but as the disk continued to rotate, the materials kept rolling, and newly added materials continued to adhere to existing small particles, like rolling snowballs, gradually growing and forming. The fertilizer particles produced by the  disc granulator  have regular shapes, mostly round spherical shapes. This perfect spherical particle has obvious advantages in the fertilization process, as it can be more evenly dispersed in the soil, ensuring a more balanced absorption of nutrients ...
