Organic fertilizer granulator is an important machine for the production of organic fertilizer and plays a very important role in the organic fertilizer production industry. Common organic fertilizer granulators on the market include: roller extrusion granulator, rotary drum granulator, disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulators, ring die granulators, and various granulators have their own production characteristics, which can be used in npk production line, organic fertilizer production lines, bio-organic fertilizer production lines, etc. Let me talk about the characteristics of pig manure granulation equipment.
1. Mixed and granulated pig manure organic fertilizer granulator
The granulation method of organic fertilizer granulation equipment can be divided into three types. One is mixing granulation. The other is extrusion granulation. There is also a common method of spray drying granulation. Mixing and granulation can be regarded as a pig manure organic fertilizer granulator. Through mechanical mixing, the materials to be processed are put into the body for mixing, and finally become the corresponding round finished product.
2. Squeeze granulation pig manure organic fertilizer granulator
Extruding pig manure organic fertilizer granulator (double roller granulator) is a widely used method. This method is usually to compact the powder material with the external force of mechanical equipment. The external force method used is basically different, which can promote the rearrangement of the solid mixture and promote the appearance of cylindrical particles of these mixtures. The production and extrusion of the whole process are mechanized, and basically no additional labor is required.Granulator organic fertilizer granulation equipment does not need to add any binder when it works, it has wide applicability, easy to use, and relatively low production cost. The moisture content of the produced organic fertilizer is also very low, which can avoid secondary drying of granular materials.
Taking the disc granulator as the core granulation equipment, the organic waste is processed into organic fertilizer.
Send the treated sludge (organic waste, industrial sludge, etc.)
and proper amount of qualified raw materials such as nitrogen, phosphorus and potassium into the raw material mixer according to the proportion and mix them evenly.2.
It is transported to the feeder, and the evenly mixed material is added to the rotating disc of the disc granulator through the continuous rotation of the disc.3.
The rotating disc and its edge produce friction and centrifugal effect on the material, which makes the material move in a circumferential direction, and the powder particles rub and squeeze each other, and gradually agglomerate into a ball.
When the gravity and centrifugal force increase enough to overcome the friction between particles, they will be thrown out of the disk, and the smaller particles will still stay in the disk and continue to gather fine particles.4.
Organic fertilizer granulation equipment is the primary and necessary granulation equipment in feed processing and manufacturing of npk fertilizer and compound fertilizer.
In the processing of raw materials, granulator can normal task production, which directly affects the economic benefits of production enterprises is directly related, so the accurate operation of granulator is very important.NPK fertilizer granulator with high degree of automation has extrusion granulation equipment, and then the organic fertilizer wet granulation machine, rotary drum granulator and other equipment also meet the processing needs of different people in different aspects, and the granulation equipment in organic fertilizer processing equipment is becoming more and more abundant.Flat die extrusion granulator, the representative product of extrusion granulation process, has a large market.
It can be formed at room temperature without drying, and can realize automatic production without manual operation, which is highly praised by most users.
Flat die pellet mill has also rapidly become a star product in the organic fertilizer production and processing industry.The important principle of compound fertilizer production by rotary drum granulator is to reduce the addition of water during granulation as much as possible, and moderately increase the temperature and solubility of materials, so as to reduce the heat consumption, improve the qualified rate of pelletizing, increase the output and reduce the production cost.As an important molding process in the production and processing of organic fertilizer, fertilizer granulator has a great impact on the organic fertilizer manufacturing process.
The strength, uniformity and size of finished organic fertilizer particles are affected by the granulation equipment.
Therefore, we will pay special attention to the selection of granulator when applying organic fertilizer granulation equipment to produce organic fertilizer.
Fertilizer production line generally uses the following methods to granulate:1.
Extrusion granulation is a method of making dry powder or wet powder containing binder into cylindrical, spherical or sheet shape by mechanical processing such as extrusion, roller extrusion or pressing.
The technology of dry granulation is used in the flat die pellet mill, the ring die pelleting machine and the double roller granulator.2.
Agglomerating granulation, which is under the action of rotation, vibration, agitation and so on, makes the wet powder in motion agglomerate.
Or use the fluidized bed to make the material obtain the cohesive force by supplying the spray liquid binder) so as to grow into the appropriate particles.
This method is used in disc granulator and rotary drum granulator.3.
