This equipment uses a pair of high-strength extrusion rollers with special tooth shapes, which can generate strong extrusion force to compress the powdery raw materials into dense granules. The granule forming rate is as high as 90% - 98%, and the granule strength is ≥12 N, which is not easy to break during transportation and storage. It has a wide adaptability to raw materials and can process various compound fertilizer raw materials with a moisture content of 8% - 15%. The equipment is equipped with a frequency conversion speed regulation system, which can adjust the extrusion speed according to the raw material properties and production requirements, realizing stable and efficient production. The roller surface is treated with wear-resistant alloy, which has strong wear resistance and long service life. The structure is compact, easy to install and maintain, and the operation is simple.
The main components of the equipment are made of 45# steel, and the extrusion roller is made of wear-resistant alloy steel. The diameter of the extrusion roller is 150 mm to 600 mm, and the length is 200 mm to 800 mm. The motor power is 15 kW to 110 kW, and the production capacity is 0.5 t/h to 20 t/h. The particle size of the produced compound fertilizer is 2 mm to 6 mm, which can be adjusted by replacing the roller with different tooth shapes. The moisture content of the applicable raw materials is 8% - 15%, and the compression ratio of the extrusion roller is 1:1.2 - 1:1.5. The overall dimension of the equipment is 2500×1500×2800 mm to 6000×3000×4500 mm, and the weight is 1500 kg to 12000 kg. It complies with the technical requirements of compound fertilizer granulation machinery and has obtained CE certification, which can be sold in the European market.
This granulator is mainly used in large and medium-sized compound fertilizer production enterprises to produce high-concentration nitrogen-phosphorus-potassium compound fertilizers, compound fertilizers with trace elements, and organic-inorganic compound fertilizers. It is suitable for the granulation of various fertilizer raw materials such as urea, ammonium chloride, potassium chloride, diammonium phosphate, and superphosphate. The produced granular compound fertilizers are widely used in the planting of field crops, cash crops, fruit trees, and vegetables. They can be applied as base fertilizers or topdressing fertilizers, which can improve the utilization rate of fertilizers, reduce nutrient loss, and promote the healthy growth of crops. In addition, the equipment can also be used in the granulation of feed additives and chemical raw materials, with a wide range of industrial applications.
