let's explain to you what the main methods of granulating organic fertilizer are.

The organic fertilizer granulator equipment uses pressure to agglomerate solid materials together, and then squeezes the materials by two counter-rotating rollers, which are driven by an eccentric sleeve or a hydraulic system. When the solid material is squeezed, the air between the powder particles is first removed to rearrange the particles to eliminate the gaps between the materials.

The extruded granulator machine for fertilizer should prevent the granulated powder material from being in the extrusion granulation equipment, and then adopt the method of external force to tightly compact the powder material. Due to the different external force methods used, the molecules are recombined to make the material appear as cylindrical particles. The whole process of generation and extrusion is mechanized operation, no manual operation is required. Stirring and granulation mainly use the method of stirring to shape the material into a round shape.

The large flakes produced by the extruded fertilizer pellet machine have a thickness of 5-20mm and a surface density of 1.5-3 times that of the feed. The large flakes are then flaked, crushed and sieved to obtain the desired granular product. The particles formed under pressure will form hot spots at the contact points to melt the material. After the temperature drops, the material cools to form a fixed bridge.

Organic fertilizer production equipment is to ferment and decompose organic fertilizer raw materials, crush them by a pulverizer and then screen them through a sieving machine for granulation processing. After the processed granules are dried and cooled, they are packaged into bags by a packaging machine and sold in the market. The entire organic fertilizer granulation process is completed by multiple production equipment, and each link complements each other to present the final product.　

There are many choices for every equipment in each link of the organic fertilizer production equipment. It is not a single fixed production mode. For example, the mixing process, our common mixers include vertical mixing, horizontal mixing, double-shaft mixing, etc. Screening can also be vibrating screen powder, drum screening; organic fertilizer granulator includes disc granulation, extrusion granulation, stirring tooth granulation, all-in-one granulation and so on.

Including organic fertilizer production equipment, the equipment and equipment transportation links can include belt conveyors, screw conveyors, and large-incline conveyors. There are many options for a single device in each link, and the entire organic fertilizer production line has more matching combinations. In addition, each device has different models, and the entire organic fertilizer production line has more options.

How to choose the organic fertilizer granulator?
1. Granulation uniformity: as an organic fertilizer granulator, its mixing effect determines the quality of the equipment, which is also an important factor for users to produce compound fertilizer granulation.

2. Wear resistance of equipment: in the fertilizer granulation process, the impact of materials on the granulation equipment often occurs, so in terms of the service life of the equipment, the more wear-resistant the material selection of the equipment is, the longer the service life of the equipment is. For users, the more cost-effective the purchase of this organic fertilizer granulator is, the lower the cost is. 

Here are some points that should be paid attention to when using organic fertilizer equipment:

One, master equipment performance:

Familiar with the operation methods, maintenance essentials, production capacity and application scope of organic fertilizer pellet machine, familiar with the functions of all equipment controllers and alarm devices, and at the same time, be sure to read the warning instructions carefully, and note that there will be a security incident the equipment continues to operate under low pressure, high temperature, etc.

Two, Familiar with operating procedures

The safe production of organic fertilizer equipment depends on the careful operation of the operators and the mastery of the technical performance of the equipment. Therefore, be familiar with and master the operating requirements of the organic fertilizer equipment, the hidden dangers of the work site and preventive measures, and discuss such issues with the managers it is the responsibility of every operator.

Three, check before starting

Before starting the organic fertilizer granulator equipment, be sure to confirm that the protective device is safe and undamaged, check whether the oil circuit system is normal, whether there is oil leakage and check whether the components in the organic fertilizer equipment are tightly installed, etc., to ensure that the equipment is free of any hidden dangers start again.

Generally speaking, the key equipment for bio-organic fertilizer production is the processing equipment before fermentation, mainly crushing and stirring equipment; the second is the turning equipment used during fermentation; the third is the deep processing equipment after fermentation, mainly the organic fertilizer granulator.

The quality of raw material processing in the early stage will directly affect subsequent production. There are various types of crushers for different materials to be crushed. For example, materials that tend to clump, long fibers, wood, etc., require different shredders. The mixing equipment can be selected according to the output. There are single continuous discharging and double interval discharging. The appropriate one can be selected according to the needs to improve production efficiency.

The fermentation process generally uses a trough-type stacker. The materials can be stacked in the trough to a higher height, which can save space and efficiently turn the stack. Of course, relatively flexible strip-stack fermentation can also be considered. This method has no special requirements on the site, But it occupies much larger area than tank fermentation.

In the deep processing stage after fermentation, that is, the fertilizer granulation process, the most important thing is the granulator machine for fertilizer. It depends on what kind of product is produced and what materials are added in it. There are dedicated organic fertilizer granulators and compound fertilizer granulators. These all correspond to materials suitable for production. Therefore, more investigations and comparisons are required when choosing bio-organic fertilizer production equipment.
