The granulation rate of the disc granulator directly affects the production efficiency and quality of organic fertilizer. When processing organic fertilizer raw materials containing high fiber and impurities, the disc granulator can take the following measures to ensure the uniformity and granulation rate of the particles: Pretreatment of raw materials: For raw materials with high fiber and many impurities, it is necessary to first remove large impurities and long fibers through crushing and screening to make the material texture more uniform, provide high-quality basic materials for granulation, and reduce granulation failure caused by uneven raw materials. Adjust the disc parameters: According to the characteristics of the material, reasonably adjust the disc inclination angle and speed. If the angle is too small, the material is easy to accumulate; if the angle is too large, the material residence time is short. Too fast speed will cause the material to be thrown out due to excessi...

In fertilizer production lines, coating machine s are far from being optional accessories. Rather, they are core devices that improve product quality and expand application scenarios. Their functionality is irreplaceable in modern fertilizer production. From the perspective of optimizing fertilizer performance, coating machines play a crucial role in precisely controlling nutrient release. By evenly spraying coating materials such as sulfur and resin onto the surface of granular fertilizer, a film with controlled air permeability is formed, allowing nutrients such as nitrogen, phosphorus, and potassium to be slowly released according to the crop's growth cycle. This slow-release effect avoids the risk of seedling burn associated with traditional fertilizers, reduces fertilization frequency, and is particularly suitable for crops with long growing periods, such as fruit trees and flowers. Without the film coating process, fertilizers are prone to rapid dissolution, leading to nutrie...

The flat die granulator is a commonly used machine for forming fertilizer granules. Its unique structure occupies a key position in small and medium-sized production lines, and its working principle and performance advantages are outstanding. The core operating principle is "extrusion molding." The machine features a disc-shaped flat die with uniform apertures at the bottom, topped by a rotating roller. Pretreated raw materials (powder or paste with a moisture content of 15%-20%) enter the machine cavity, where the rotating rollers continuously press the raw materials against the die surface. Under pressure, the raw materials are squeezed into the die holes, forming cylindrical strands. These strands are then cut into pellets of a desired length by a cutter located outside the die holes. The entire process eliminates the need for high-temperature melting, relying solely on mechanical extrusion and physical molding. This makes it suitable for processing heat-sensitive raw mat...

As an essential conveying device in fertilizer production lines, bucket elevator s, with their unique advantage of vertical conveying, connect various processes, including raw material processing, mixing, granulation, and packaging, providing critical support for continuous production line operation. During material transfer, they overcome the height difference problem that horizontal conveying equipment struggles to overcome. Whether feeding crushed raw materials into a mixer or transferring granulated semi-finished products to a screening machine , the bucket elevator's continuous action of scooping, lifting, and tipping enables efficient vertical conveying. This significantly reduces workshop floor space and allows for a more compact and rational production line layout, making it particularly suitable for small and medium-sized production sites. The bucket elevator's highly adaptable conveying capacity allows for flexible model selection based on production line capacity. F...

Engine power is transmitted to the drive shaft through the speed reducer, driving the tipping gears to rotate at high speed. During operation, the rotating tipping gears penetrate the material pile, tipping and breaking up the bottom layer of material upwards and simultaneously pushing the surface layer dow...

Whether it is an organic fertilizer production line or a compound fertilizer production line, the granulation link is the key node that determines the product quality and production efficiency. With its unique design and excellent performance, the rotary drum granulator has become the core equipment of many fertilizer companies. It can improve the quality of finished fertilizer products from the root. When using wet granulation technology, the material is fully mixed, chemically reacted and mechanically extruded in the rotating cylinder to form particles of uniform size and within the ideal range. This kind of granules not only have high hardness and strong resistance to crushing, but are not easy to pulverize during transportation and storage, and the dissolution rate is controllable, which can meet the nutrient needs of different crops in different growth periods. The high balling rate means that the proportion of unqualified products is extremely low, and a small amount of return...

  The large amount of chicken manure produced by chicken farms every day was once a headache for farmers - it piled up and occupied land, the odor disturbed people, and polluted the environment. Today, with the upgrading of environmental protection technology, chicken manure has transformed into high-quality organic fertilizer, and this "gorgeous transformation" is inseparable from the help of professional processing equipment. The core of chicken manure turning into fertilizer is composting and fermentation. Fresh chicken manure contains a lot of pathogens, insect eggs, and a strong smell of ammonia nitrogen. Direct use will burn the roots of crops and attract pests and diseases. Therefore, the first step is to "disinfect and improve the quality" of chicken manure. First, send the chicken manure to the de watering machine   to remove excess water. The dehydrated chicken manure cannot be fermented directly, but must be matched with straw and sawdust to adjust the ai...

The potassium fertilizer is fed into the disc granulator, so that the material gradually piles up by itself until it reaches the required particle size. When the raw materials are piled up on the disc, the binder can be added to support the agglomeration of the materials. Since water will be added to the disc during granulation, additional drying process is required for the fertilizer production line when using this method of rolling raw materials into balls. Advantages and disadvantages of potash fertilizer granulation 1. The granulation of potash fertilizer has many advantages. This non pressure agglomeration technology can produce particles with smaller density, so that the particles can decompose rapidly. Because most of the potash fertilizer can be used as fertilizer after processing, the ability to decompose and provide nutrition faster is the inducement to choose potash fertilizer particles. It is an ideal product for fertilizer compounds with fixed formula requirements th...

Mixing granulation of different NPK fertilizers is the core of compound fertilizer processing. 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 extrusion 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 roatry drum granulator. 3. Crushing granulation, which is to crush the block material into particles of appropriate size. ...
