Firstly, this extrusion granulation process is short and does not require drying and cooling, cutting input and operational expenses.Then, high finished products rate and granulation ratioup to 95%. Despite their coarse surface, fertilizer granules have good curing property, high strength and obvious increases in volume weight.
What's more, it is be of use to produce a variety of high, medium and low concentration of special NPK compound fertilizers. It is highly adaptable to materials and provides additive-free compression granulation.
Moreover, if the pressure exceeds the set limit, you can promptly intervene to prevent any potential damage to the equipment.
Additionally, small roller granulator size saves site area and engineering cost, as well as equipment cost.
Besides, normal temperature production; the product is rolled and formed at one time; various parameters can be adjust.
Firstly, you should start by preparing the raw materials, ensuring they are of the correct particle size and moisture content to facilitate optimal granulation. Once the materials are adequately prepared, you can proceed to feed them into the granulator's hopper. It is essential to maintain a steady feed rate, as inconsistent feeding can lead to uneven granules or machine blockages.
During the granulation process, the raw materials are compacted under high pressure between two rotating rollers. It is crucial to regularly monitor the pressure and adjust it accordingly to achieve the desired granule hardness and size. Additionally, temperature control is vital as excessive heat can lead to material degradation or safety hazards.
After granulation, the granules are often passed through a screening process to separate the desired size fraction from the fines and oversized particles. The appropriate granules are then collected for packaging or further processing, while the fines can be recycled back into the system to optimize material usage.
Initially, the machine is designed to handle a variety of powdery materials, primarily those used in the production of fertilizer,such as ammonium nitrate, urea, ammonium chloride, sulfate of potash, phosphate rock powder, and other similar substances.
Then, divided into categories, these raw materials include nitrogenous bases like urea, calcium sources such as lime, and phosphatic elements including rock phosphate.
What's more, potassium-bearing materials like potassium chloride and potassium sulfate, often in the form of sulfate of potash, are essential for creating comprehensive NPK blends.
Additionally, micronutrients and binding agents also play a pivotal role in ensuring the integrity and efficacy of the final granules.
In practical applications, the roller granulator in the NPK fertilizer granulator is widely used in the agricultural sector to produce high quality fertilizer mixtures suitable for specific crop needs.
