Batching materials with required formula
To produce commercial fertilizer granules with required proportion, the industrial batching machine can help you a lot. With PLC control system and electronic belt scale or nuclear scale, it will feed materials for fertilizer granulation with high precision – 2‰.
Here, to fully meet your requirements of compress fertilizer pellets making with multiple and single material, in a large and small scale, YUSHUNXIN specially design 3 types fertilizer batching machines for you. They are dynamic batching machine with various materials feeding simultaneously, static batching equipment with one by one feeding, and loader feeder for fertilizer granulation with single material.
Mixing powder materials evenly
Then, if you make granular fertilizer from multiple materials, such as the NPK fertilizer granulation, the mixing is necessary to ensure the nutrient balance.
For this, YUSHUNXIN fertilizer mixer can help you blend powder evenly in a large scale quickly because of advanced design. For example, the double shaft horizontal mixer, which is designed with two counter-rotating stirring shafts, process fertilizer materials by continuously lift, toss, and shear to disperse. So, you can prepare fine powder mixture material with balance nutrients for fertilizer pellet making.

Roller granulator work to make compress fertilizer pellets
This is the most important step in fertilizer roller extrusion granulation line. In this process, the mixed material will be granulated into flat ball cakes under the action of rollers extrusion force. Next, there are stirring shaft and sieve to disperse compress cake into fertilizer pellets. In general, there are double roller granulators with 1-4 TPH capacities for your choice.
Then, to prepare fertilizer pellets with uniform size, you need to screen granulated fertilizer particles quickly. Here, a rotary sieving machine is an idea choice.
This machine can screen out granular fertilizer with required size in a short time. But, how to dispose of the fertilizer particles with small and large size? Only need to add a chain crusher near the fertilizer pellet sceener. This will grind the left fertilizer granules into powder and you can return them to double roller extrusion equipment to granulate again.
