Double Roller Pressing Granulator for Fertilizer Production
The Double Roller Pressing Granulator is a prominent tool in the dry granulation process used for the compaction of powdered raw materials into solid granules. This equipment operates through roller compaction, a dry granulation method known for its simplicity as it neither involves chemical reactions nor requires the drying and cooling of materials. The machine utilizes pressure to compact materials between two counter-rotating rollers, often made from high-quality steel to withstand wear. It finds application in the production of fertilizers, notably potassium chloride, thermal phosphatic fertilizers, and ammonium sulfate, as well as compound and bulk blending pellets. The granulator is appreciated for its high granulation rate and strong adaptability to various raw materials. It notably enhances production efficiency by reducing dust and thus, improving environmental conditions. Careful attention to the moisture and temperature of the materials is crucial to ensure optimal performance and extend the lifespan of the granulator.The roller compaction granulation technique is currently the main granulation method for making powders. It is becoming increasingly essential with the improvement of automation. This technique is a process that uses pressure to cause solid materials to aggregate, with two counter-directional axes squeezing them.
When the material is squeezed, the air between particles is expelled, and strong van der Waals forces are generated between the particles, causing the structure to be reorganized.
A double roller pressing granulator also called a double roller extrusion granulator, is suitable for granulating potassium chloride, thermal phosphatic fertilizer, ammonium sulfate, and various compound fertilizers. Besides, it is suitable for your bulk blending pellet fertilizer production line. Is Granulation Roller Compaction Process Wet Or Dry '
Granulation?
Roller compaction technology is a typical way of dry granulation and it belongs to the pressure molding granulation method. According to the different external force systems applied, pressure molding can be divided into the die pressing method, extrusion method, and extrusion rolling granulation method.
This granulation method and equipment can be widely used in fields like pesticides, fertilizer, and feed. If you have the intention of making small-scale compound fertilizers, a double roller granulator is fit for you, for the double roller granulation process is simpler than another wet granulation process.
Roller granulation is a dry method of powder granulation without any chemical reactions, so the production process is simple. Therefore, you don't bother drying and cooling of the material.
MFP company also manufactures the whole set of dry granulation equipment. For example, we have introduced a compound fertilizer production line in our previous post. This production line can produce 10.000 TPH granular compound fertilize .
- Strong adaptability, high capacity, uniform granule size, good granule strength, and high granulation rate. You can use a double roller extrusion granulator to make pellets directly without preprocessing, which can save both your time and energy.
- Reduces dust pollution and improves the environmental conditions of the production process.
- It is environmentally friendly. Because the whole production process doesn't release odor. It can help you reduce bad smell of organic manure to a maximum.
