Recently, we sent an NPK compound fertilizer roller press granulator to Indonesia. The roller press granulator is a key device in the compound fertilizer production line
Uses and characteristics of Indonesian compound fertilizer roller press granulator:
The dry-free extrusion granulation process of the Double roller press granulator has a wide range of applications in powder processing granules. Its characteristic is that it does not need to humidify or heat the material, and the material can be directly processed into granules. It can be used for the processing of organic and inorganic fertilizer granules and feed granules.
Utilizing the non-drying extrusion granulation process, no wastewater or waste gas is discharged outside during the production process, and it will not pollute the environment. The extrusion granulation process is short, the operation is simple, and it is convenient to realize automatic production control and improve production efficiency. There are no special requirements for the properties and particle size distribution of raw materials, so the source of raw materials is wide.
Advantages of fertilizer granulation:
Fertilizer granulation is one of the development trends of fertilizers. Compared with powdered fertilizers, granular fertilizers have good physical properties, no dust, long-term storage, no agglomeration, good fluidity, easy-to-spread fertilizer, and can realize aircraft sowing. At the same time, it can also play a slow-release effect and improve fertilizer performance. Utilization rate.
Non-drying granular fertilizer process:
Non-drying granular fertilizers include urea, ammonium phosphate, compound fertilizer, potash fertilizer granules, etc. The processing methods for processing such non-drying granular fertilizers are usually disc granulation, recrystallization, and extrusion granulation. After long-term practice Experience, we recommend using a Double roller granulator to process non-drying granular fertilizer, this kind of extrusion granulation processing is more practical.
Indonesian roller press granulator production process:
1. Add the qualified raw materials into the mixer according to the ratio requirements and mix them evenly.
2. It is transported to the disc feeder to remove the metallic substances in the material during the transportation process.
3. The materials in the disc feeder enter the granulator evenly, and the materials are forced to pass between the two pressure rollers and extruded into thin sheets. The thin sheets are broken into fragments by the coarse crusher under the pressure roller for screening.
4. The semi-finished products passing through the granulator are transported to the sieving machine for screening, the fine particles after sieving are returned to the feeder, and the large particles enter the pulverizer and then enter the feeder.
5. The screened qualified products are transported to automatic weighting and packing machines for weighing, packaging, and warehousing.
Tianci roller press granulator manufacturer:
The non-drying extrusion granulation process basically uses a Double roller granulator is the main machine of granulation. The process design of Zhengzhou Tianci Heavy Industry in the Double roller press granulator is rich in experience, good design concepts, equipment replacement, and upgrading, and has made great progress. It is the most popular non-drying extrusion granulator process in the market. equipment.
