Simple operation of dry powder extrusion granulation equipment double roller granulator
2023/05/17
The double roller granulator mainly relies on the external pressure mode, so that the materials are forced to pass through the gap between the two opposite rotating rollers and compress into pieces. The actual density of the material can be increased by 1.5-3 times to reach a certain strength standard. It is especially suitable for increasing the proportion of product stack. The equipment is not only scientific and reasonable in structure, but also low in investment, quick in effect and good in economic benefit.
The working principle of dry extrusion double roller granulator is very simple, and it has four functions
1. In order to ensure the continuous feeding of fertilizer granulation machine during extrusion granulation, screw conveyor and vibrating conveyor are generally used as feeding equipment;
2. Then there is the forced feeding system, which is to control the feeding speed. As if the feeding speed is uniform, it can increase the feeding amount and increase the output. Its biggest function is to pre degass and apply pressure in advance, so as to make the product quality higher;
3. Double shaft output is adopted for roll extrusion, which can effectively improve the speed of transportation, protect the bearing capacity of the main shaft, reduce damage and improve the transmission effect. It can make the hydraulic cylinder have stable pressure and make the floating roller heel run smoothly.
4. Granulation: the material sent through the conveyor driven by the motor is crushed by the chopping system, and then the powdery material is evenly added into the binding plate for shaking, and then enters the roller mouth after forced degassing and pre pressing. According to the requirements of the particle specifications, with the rotation of the roller, the molding is gradually achieved. Then the automatic demoulding process is completed.
The pig manure organic fertilizer production line adapts to the strategy of commercializing organic fertilizer management and promotes the formation of the production industry chain. It is a process equipment that integrates industrialization, marketization, and large-scale production development, which is conducive to the sustainable development of agriculture. Not only does it effectively promote the development of ecological agriculture, but it is also a choice for the development of agricultural circular economy.
