Commonly used granulation equipment for organic fertilizers are: disc granulator, counter-roll granulator, drum granulator, wet granulator, counter-roll extrusion granulator, flat die granulator, ring film granulator Granulator. In the npk fertilizer production line, the roller extrusion granulator is very common.
Granulation raw materials: It can be used for granulation of organic fertilizers such as livestock manure, kitchen waste, industrial waste, straw leaves, trough residues, oil cakes, etc, compound fertilizer granulation such as npk production line, and chemical and feed grain.
The structure of the double roller granulator: the key structure is the roller and the mold, the belt and the pulley are driven by the motor, transmitted to the driving shaft through the reducer, and the split gear and the passive shaft work synchronously in the opposite direction. The material is added from the feeding hopper, extruded by the rollers, demolded into balls, and sent to the crushing screen through a pair of chain transmission. The equipment of the counter-roll granulator is relatively small, the production capacity is low, and the price is relatively cheap, generally 30,000 to 50,000 yuan;
Advantages of roller granulator:
1. High product granulation rate: dry powder is produced at room temperature without drying, and the product is extruded at one time, which meets the technical requirements of compound fertilizer.
2. Large output: The design is reasonable, and it can be used with the corresponding equipment to meet the continuous production of the production line.
3. Low energy consumption: advanced technology, compact structure, novel and practical, low energy consumption.
4. Wide range of application: The size of the extrusion force can be adjusted by hydraulic pressure, and the operation is flexible. It is suitable for various industries such as fertilizer, medicine, chemical industry, and feed.
