The double-roll extrusion granulator is the key equipment for compound fertilizer granulation. It has advanced technology, reasonable design, compact structure, novelty and practicality, low energy consumption, and can be matched with corresponding equipment to form a small production line, which can form a continuous and mechanized production with a certain capacity. It adopts eugenics formula, does not require drying, is produced at room temperature, and the product is rolled and formed in one time, so that the product quality meets the technical index requirements of compound fertilizer. It is a replacement product for the production of high, medium and low concentration special compound fertilizers for various crops and energy saving and consumption reduction in the compound fertilizer industry.
1. No drying process, granulation at room temperature, one-time molding, low investment, quick results, good economic benefits.
2. Low power, reliable operation, no three wastes, stable operation, easy maintenance.
3. Can be used for granulation of various raw materials such as compound fertilizers, medicine, chemicals, feed, coal, metallurgy, etc.
4. The double-roll extrusion granulator, especially the granulation of rare earth, ammonium carbonate, and ammonium sulfate compound fertilizers, fills the domestic gap.
The working principle of the roller granulator is: the motor drives the belt and pulley, which is transmitted to the driving shaft through the reducer, and synchronized with the driven shaft through the split gears, working in
opposite directions. The material is added from the feed hopper, extruded by the rollers, demolded into balls, and then conveyed to the crushing screen studio through a pair of chains, screened and separated into finished particles
(balls), and then the returned material is mixed with the new material and granulated. With the continuous rotation of the motor, the continuous entry of materials can realize mass production.
