Extrusion granulation is simple and practical. After fermented compost is adjusted to a moisture content of 20% to 30%, it can be directly entered into the granulator and extruded into cylindrical granules.Disc granulator machine or drum granulation principle of the agglomeration method , in the npk production line, this granulation method is very common and very practical, but for organic fertilizers, since the moisture content of organic compost after fermentation is generally about 30%, the compost has coarse particle size and fiber. It is difficult to agglomerate into granules when using disc or drum granulation methods.
Let's talk about the agglomeration method organic fertilizer granulator:
Disc granulator machine
The granulation method of disc granulation is wet granulation, and the granulation raw materials are usually biological organic fertilizer, coal powder, cement, clinker, chemical fertilizer, etc. In the npk fertilizer production line, the capacity is about 0.02-6t/h, and the disc granulator is a more traditional granulation process. Personally, I advocate this granulator, the granulation is smooth, the sales are good, and the price of the equipment is low.
Rotary drum granulator
The granulation method is wet granulation, which can be used for the granulation of livestock and poultry manure, composted manure, green manure, sea manure, cake fertilizer, peat ash, soil and miscellaneous fertilizer, three wastes and microorganisms. In the npk fertilizer manufacturing process, the production capacity is about 1-35t/h, and the granulator is a compound fertilizer granulation process, which can also be used to produce organic fertilizers.
Tooth granulator
The granulation method is agglomeration wet granulation, which is widely used in the granulation of municipal waste organic fermented fertilizers such as livestock manure, carbon black, clay, kaolin, three wastes, green manure, sea manure, microorganisms, etc. Quality powdery material. 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 process has high output, and the processing and granulation can be comparable to disc granulation.
