The equipment of npk production line basically includes batching machine, pulverizer, mixer, granulator, dryer, cooler, screening machine, automatic packaging machine, belt conveyor, etc. The granulator is a necessary equipment for the production of granular organic fertilizer. What are the characteristics of the roller extrusion granulator?
1. The organic fertilizer double roller granulator has low energy consumption: extrusion granulation is the granulation of materials at room temperature. Compared with other granulation methods, it does not require drying measures such as fuel oil and gas. The production requires only electricity and a very small amount of cooling water (for roller cooling), only about 30 kW/h per ton of product.
2. There is no need to add additional binders: other granulation processes are basically wet processes, and there must be a drying process, corresponding to high energy consumption and high product moisture. In the npk manufacturing process of organic fertilizer roller extrusion granulator, dry granulation does not require additional additives, and only needs to use the intermolecular force of the material itself, which simplifies the process and reduces energy consumption.
3. The organic fertilizer roller extrusion granulator has low investment: because the drying process is omitted, and the material return ratio is low (accounting for about 35% of the total extruder feed), the process flow is simple and the investment is low.
4. A wide range of applicable raw material particle specifications: extrusion granulation has no special requirements for the particle size of raw materials, both 1~4mm granular materials and fine powder materials are available, and powdery materials and powder products with unqualified particle size are better to use , the use of powdered materials can reduce costs.
5. The organic fertilizer roller extrusion granulator has a wide range of capacity: for the extrusion granulation device, the effect of economic scale is not obvious, and the device capacity is 1~50 t/(h. Taiwan) can be designed more economically, Therefore, it is applicable to a wide range of capabilities.
