What type of granulator equipment for organic fertilizer production line? What are the pros and cons?
The organic fertilizer granulator is one of the core equipment of organic fertilizer equipment, which directly affects the quality of organic fertilizer particles (roundness, uniformity, fertilizer and water retention performance, etc.).
Therefore, what is the difference between several processes of organic fertilizer granulation? What is the impact on product quality? Different types of granulators should be used, which directly affect the output, quality, appearance, price, etc. of the product. It can be said that the organic fertilizer granulator is the core of the entire production line. Which granulator is suitable for making organic fertilizers? Let’s take a look at the related questions about the granulator.
The raw materials for the production of organic fertilizers come from a wide range of sources, including plant residues, peat soil, humic acid, cow manure, chicken manure, sheep manure, duck manure, free manure, sludge, sugar mill filter mud, winery lees and so on. In response to different raw materials and the requirements for product quality and product output improvement, various organic fertilizer equipment manufacturers have developed various granulators, such as roller extrusion granulators, spinning granulators, disc granulators, new Organic fertilizer granulator, new compound fertilizer granulator, flat die granulator, ring die granulator, etc.
First, let’s talk about the pros and cons of each granulator.
Roller extrusion granulator
The roller extrusion granulator belongs to dry granulation, no drying process is required, and the granulation density is high, the fertilizer effect is good, and the organic matter content is full. Save the cost of buying dryer and cooler, no need to burn coal in the later stage, which saves a lot of money. However, the granulation shape of the extrusion granulator is flat and round, it is easy to get stuck when planting in the field crop machine, and the flowability is not very good. Therefore, if organic fertilizers produced by machine-seeded farmers should use this granulation process with caution, it is recommended to choose compound fertilizers and compound fertilizers.
Drum granulator
Turning granulator is a process of compound fertilizer granulation, and can also be used to produce organic fertilizer, but the granulation rate is low.
Disc granulator
A disc granulator is a more traditional granulation process. We advocate this kind of granulator, the granulation is smooth, the sales are good, the equipment price is low, the only disadvantage is the low density.
Toothed organic fertilizer granulator
The mixing tooth organic fertilizer granulator is currently the most popular product on the market, and it is also a product widely loved by customers. If the organic fertilizer rounder is added, the yield of this process is high, and the granulation can be comparable to that of disc granulation. But need to buy a dryer and cooler.
Ring Die Granulator
The ring die granulator has the highest granulation density, and the granules will not be scattered in the process of sales and transportation, but a round polishing machine must be added in the later stage to realize the round granule finished product. This kind of granulation process is expensive.
The above are the advantages and disadvantages of the mainstream granulation process in the market, you can choose the granulator that suits you.
