4.5mm fertilizer pellets making machine
Working method
Raw materials are sent into hopper by fixed quantity feeder, when two rolls parallel each other horizontally, powder materials are continuously and evenly fed in the gap between two rollers by their gravities and forced compression. Then we get the round shape granular, but in order to get the better results, we suggest using a rotary screen to sieve the final products, qualified products will be put into bags, and unqualified products will be recycled mix with new material for the next granulating process.
Fertilizer pellets making machine
Summary
- Offers higher bulk specific gravity. (Materials can be processed without being bulky.)
- Maintains stability of bulk specific gravity.
- Improves liquidity. (It facilitates constant feeding, weighing, and others.)
- Eases the system handling.
- Prevents materials from scattering (i.e., improves the working environment).
- Facilitate mixing of materials.
- Provides smooth melting of materials (in other words, hardly forms lumps of materials).
Features
- Simplified manufacturing process
By dry-process granulation, you require no humidification and drying stages. - Minimal transformation
This system is the best-suited to granulate materials which are unstable to water or solvent and subject to thermal transformation. - High-density products
By compaction with pressure rollers, you can produce high-density particles and granulated powder. - High compression force
The High-pressure Type Roll Compactor offers larger compression force, enabling you to produce high-density and high-intensity products. - Soft granulation
Even though the hydraulic cylinder is used to apply compression force, since the operative pressure of the hydraulic cylinder can be easily adjusted, you are able to reduce the compression force for soft granulation. - Incorporation of high-performance screw
The screw performance exerts a significant influence upon the granulating capability of the Roll Compactor.
The Roll Compactor has a high-performance screw, which have materials intruded between the rolls to facilitate de-gassing. - Efficient crushing and granulation
By freely varying combination of breakers, several types of granulators for fine particle and sizing use, and granulators with screen, you can efficiently get a target particle size.

Layout of Fuyi Roller Presses
Powder are entered into a roller press and compacted between the rollers to a strip with high density.
We can design different diagram for different clients, we need to design the layout according our clients provide us some basic information about the size of their factory, and how do they want to place the equipments. Our target is making the process simpler, easier, more economic and more effective.
Service
Fuyi has designed and manufactured roller presses and equipments for briquetting and compacting NPK fertilizer, powder, chemical, minerals, etc, since 2006. We take care of green field projects as well as of existing plants. Our services cover material tests, process layout, engineering, and supply of complete granulating plants or key equipments, guidance of installation and commissioning, training.
