The granular fertilizer production line mainly involves a series of equipment that work together to complete the entire process from raw material processing to finished granules. The following are the main equipment that may be needed in a granular fertilizer production line and their brief descriptions:
1. Raw material processing equipment:
Crusher: used to crush large pieces of raw materials into a particle size suitable for subsequent processing.
Mixer: Mix various raw materials and additives in a certain proportion to ensure the quality of the finished granules.
2. Granulation equipment:
Disc granulator: The mixed material is squeezed into small spherical particles through a rotating disc. This granulator is widely used in the production of granular fertilizers such as organic fertilizers and compound fertilizers.
Double-roll extrusion granulator: It uses two relatively rotating rollers to squeeze the material into granules, which is suitable for the granulation of a variety of materials.
Spheronizing machine: The initially formed granules are rounded to improve the roundness and appearance quality of the granules.
3. Drying equipment:
Dryer: Dry the wet granules after granulation to remove excess moisture and meet the specified moisture content requirements. Common drying machines include hot air circulation ovens, boiling dryers, etc.
4. Cooling equipment:
Cooler: Cool the dried particles to prevent the particles from deteriorating due to high temperature during subsequent packaging or storage.
5. Screening and grading equipment:
Vibrating screen: Screen the particles according to size to separate unqualified particles and impurities.
Grading machine: Further grade the particles to meet the needs of different customers.
6. Packaging equipment:
Automatic packaging machine: Automatically measure, package and seal qualified particles to improve production efficiency and packaging quality.
In addition, other auxiliary equipment may be required, such as conveyor belts, storage bins, dust removal equipment, etc., depending on the specific needs and scale of the production line.
It should be noted that the equipment configuration of the spherical granulation production line for different industries and products may vary. Therefore, when selecting equipment, it is necessary to customize and configure it according to the production needs and product characteristics of the granular fertilizer production line.
