The complete set of organic fertilizer equipment includes: chicken manure dehydrator, fermentation stacker, semi-wet material grinder, horizontal mixer, disc granulator machine, dryer, cooler, trommel screen, coating machine, packaging equipment, belt conveyor, etc. The conveyor is evenly and continuously fed into the npk fertilizer granulator, and it is rounded into spherical particles by the polishing and shaping machine. The belt is conveyed to the finished product silo.
In the organic fertilizer npk manufacturing process, not only the water content of the granules after forming generally exceeds the index and needs to be dried at low temperature, but also the water content of organic raw materials after fermentation is about 30% to 40%, and the water content of the granules after granulation is generally in Between 15% and 20%, the fertilizer quality index requires that the moisture content is less than 14%, and it needs to be dried. Therefore, the drying section is an indispensable and important process in the production process of biological fertilizers, which directly affects the output, quality and energy consumption. It is very important to choose the model and specification of the dryer reasonably and control the process conditions.
1. Due to the different conditions and humidity of the dried materials, there may be large differences. Therefore, when using the dryer, it is necessary to understand the material structure in the production process of the organic fertilizer fermentation tank.
2. The drying characteristics will change with the state of the material. The organic fertilizer fermenter has different moisture characteristics in different materials, so it has a great impact on the internal structure of the equipment.
3. In order to enable the material to be supplied, conveyed and discharged smoothly, the organic fertilizer fermentation tank is heated during the production process. Even if the organic fertilizer fermentation tank can barely operate, it must be considered from the aspects of automation and other engineering. In order to achieve efficient drying, it should also be considered Operation of other units, auxiliary equipment technology, etc. That is to say, the drying operation is the embodiment of a comprehensive technology.
