Non-drying granular fertilizers include urea, ammonium phosphate, compound fertilizer, potash fertilizer granules, etc., and 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 without agglomeration, good fluidity, easy to spread fertilizer, and can be used to spread fertilizer by plane. At the same time, it can also play a slow-release effect and improve fertilizer performance. Utilization rate.
Granular fertilizer processing granulator is mainly used for processing compound fertilizer and compound fertilizer. Commonly used non-drying granular fertilizer processing granulators include disc granulation, total crystallization method, and extrusion granulation. The three granulation methods have their own characteristics. Here, Tianci recommends a twin-roll extrusion granulator.
(1) Disc granulation. Disc granulation requires adding a binder to the powder, and at the same time, it is obtained by drying and sieving. This method requires the addition of ineffective ingredients such as binder (usually clay) and water to reduce the nutrient content of the product.
(2) Recrystallization method. The powder is dissolved in water, cooled, crystallized, and separated into crystals, and then crushed and sieved. The method has a complicated process, high cost, high consumption, and low market competitiveness.
(3) Extrusion granulation method. A tablet press or an extrusion granulator is used to forcibly squeeze the powdered potassium fertilizer into tablets, which are then made into granules through processes such as slicing, granulating, and sieving. There are two types of extrusion granulation: roller type and wheel roller type. The roller-type extrusion is firstly pressed into large pieces and then crushed into particles so that the device has a large capacity, high particle strength, and low energy consumption. The wheel rolling type is to directly squeeze the material into a cylindrical strip in the laminating film, and then cut it into columnar particles. Most of the extrusion granulation methods currently used in China are wheel-rolling granulation. The production scale is small. A single machine can only reach 3~5t/h, and the granulation strength is limited, the mold is damaged, and the production is cylindrical granules. , Poor flow performance and other characteristics.
The roller extrusion granulator adopts rolling molding and crushing into granules. Extrusion granulation production has a wide range of raw materials. At present, there are more than 20 kinds of materials that have been successfully used for extrusion granulation: ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc. In addition, the extrusion granulation process can flexibly realize the replacement of product formulas in a very short time, and a set of equipment can produce products with more than 30 formulas.
