The equipment configuration of an NPK fertilizer production line may vary depending on the production process, but generally speaking, a complete NPK fertilizer production line will include the following main equipment:.jpg)
Raw material storage and transportation equipment: used for storing and transporting various raw materials (such as urea, monoammonium phosphate, potassium chloride, etc.). Including raw material warehouses, conveyor belts, screw conveyors, bucket elevators, etc.
Raw material crusher: used to crush raw materials to a particle size suitable for subsequent processes. Common types include hammer mills, cage mills, roller mills, etc.
Ingredient system: Accurately weigh various raw materials according to formula ratios, usually including electronic scales, ingredient hoppers, etc.
Mixing equipment: Mix various raw materials thoroughly and evenly. Commonly used types include disc mixers, horizontal mixers, vertical mixers, etc.
Granulation equipment: Mix the evenly mixed raw materials into granules. Common types include disc granulators, drum granulators, extrusion granulators, etc.
Drying equipment: used to remove the water added during the granulation process, so that the fertilizer particles reach the required moisture content. Commonly used ones include rotary drum dryer, fluidized bed dryer, etc.
Cooling equipment: Cool and dry fertilizer particles to prevent clumping and improve storage stability. Commonly used ones include drum coolers, fluidized bed coolers, etc.
Screening equipment: used to screen out particles that do not meet the particle size requirements, commonly including vibrating screens, drum screens, etc.
Packaging equipment: Quantitatively package qualified fertilizer granules, commonly used include automatic packaging machines, sealing machines, etc.
Dust removal equipment: used to collect and process dust generated during the production process to meet environmental protection requirements. Commonly used ones include bag filters, cyclone dust collectors, etc.
Control system: including PLC control cabinet, touch screen, sensors, etc., used to automate the operation of the entire production line, improve production efficiency and product quality.
These devices constitute the main part of the NPK fertilizer production line, and the selection and configuration of each device need to be determined based on specific production needs, raw material characteristics, production capacity requirements, and other comprehensive factors. When designing a production line, it is also necessary to consider the connection between equipment, material transportation paths, energy consumption, and environmental requirements to achieve efficient and stable operation of the production line.
