Exploring the fertilizer processing technology of roller extrusion granulator

 The roller extrusion granulator contains unique secrets in the fertilizer processing process, which have contributed to its important position in the fertilizer production industry.

Careful pretreatment is essential before the raw materials enter the rroller extrusion granulator. Organic fertilizer raw materials usually undergo sufficient fermentation to remove harmful substances such as bacteria and insect eggs, while improving the physical properties of the materials. The crushing process is also crucial, as the raw materials need to be crushed to the appropriate particle size, generally controlled at a few millimeters, to ensure the smooth progress of subsequent granulation.

When the raw materials that meet the requirements are transported to the feed inlet of the roller extrusion granulator, the granulation journey officially begins. Two rollers rotate towards each other at the same linear velocity, creating a strong squeezing force between them. Under this squeezing force, the raw materials are forcibly filled into the grooves on the surface of the roller. The groove design of the roller is ingenious, and its shape and size directly determine the final shape and size of the fertilizer particles.

As the rollers continue to rotate, the extruded cylindrical particles are slowly squeezed out from between the rollers. At this point, the cutting blade installed at a specific location comes into play. The cutting blade accurately cuts through continuous cylindrical particles according to the set length, and in an instant, regular fertilizer particles are born.

The processing mystery of the roller extrusion granulator is also reflected in its protection of fertilizer nutrients. Due to not relying on additional binders to assist in granulation, various nutrients in the fertilizer are fully preserved. This means that the fertilizers produced can release nutrients more effectively when applied to the soil, providing sufficient and long-lasting fertility support for crops.

In addition, the flexibility of the device is also a major mystery. By replacing rollers of different specifications, manufacturers can easily adjust the shape, size, and strength of fertilizer particles. Whether it is round, oval or other special shaped particles, they can be produced according to demand to meet the diverse needs of different customer groups and markets.

In terms of production efficiency, the roller extrusion granulator also performs well. Its continuous and stable working mode can produce a large number of fertilizer particles per unit time, providing strong support for large-scale fertilizer production.

Exploring the secrets of fertilizer processing with the roller extrusion granulator, we have seen its outstanding performance and unique advantages in fertilizer production, contributing an important force to the sustainable development of agriculture.

A series of processing and organic fertilizer manufacturing machine can realize the resource utilization of animal manure and straw waste such as chicken manure, sheep manure, cow manure, etc. What are the manufacturing processes of organic fertilizer? What equipment is needed in this production process? After the compost fermentation is completed, the compost is crushed into powder in the organic fertilizer crusher. The powder is mixed into the organic fertilizer mixer to add auxiliary materials for mixing. After mixing evenly, the compost is put into the granulator to make particles. The particles are sent into the dryer to reduce the moisture content of the particles to 10-20%. After cooling, the compost is sent to the cooler for screening, and the unqualified products are screened out for recycling The belt conveyor enters into the pulverizer again to crush and screen out the finished products, which can be packaged directly. Composition of organic fertilizer manufacturing e...
