The working principle of the disc granulator in the fertilizer production line

fertilizer granulator Nov 19, 2019

The disc granulator machine is mainly used in the NPK fertilizer production line and organic fertilizer production line to produce various granular products; it’s also used in pharmaceutical products, fertilizers, feeds, etc. Adopting the overall arc structure, the granulation rate can reach above 93%. The granulation tray has three discharge ports, which facilitates intermittent production operations, greatly reduces labor intensity and improves labor efficiency.

Disc fertilizer granulator machine working principle:
The raw meal powder is uniformly wetted by the atomized water in the mixer to form a spherical core having a uniform particle size, and then fed into a ball plate for ball formation. The moisture of the ball should be controlled at 12-14%. Most of the water should be added in the twin-shaft mixer. Only a small amount of supplementary water is added to the ball plate, and the amount of water added is controlled to be about 0 to 3%. The dry powder granulation is directly added to the ball-forming plate, and the proper amount of water is sprayed. The raw material nucleus enters the spherical disk and is subjected to centrifugal force, friction and gravity in the disk, and moves along the parabola. Due to the cohesiveness and plasticity of the material, the cores are bonded to each other and gradually grow up during the movement. When the inclination angle of the ball disc, the height of the disc edge, the rotation speed and the moisture are constant, the balls of different particle sizes roll downward from the edge of the disc at different disengagement angles due to different gravity. During the continuous rolling process, the ball continuously discharges the water in the ball out of the surface. Due to the cohesiveness of the material and the natural volatilization of the surface liquid film, the ball has certain strength, and then the disk is rotated with the tilting of the disk. The sides are discharged out of the pan.

Disc granulator performance advantages:
1. The raw materials are suitable for a wide range of applications. They can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical feed, coal, metallurgy, etc., and can produce various concentrations and various types (including organic fertilizer, inorganic fertilizer, and magnetic fertilizer etc.) of compound fertilizer.
2. The disc granulator is light in weight, low in height, and flexible in process;
3. The machine has simple structure, convenient adjustment and superior performance.
4. The use of unique unpowered combination scraper integration reduces auxiliary power consumption.

5, high ball formation rate, large rounded particle strength, intuitive operation, easy maintenance and so on.

Fertilizer granulator machine is the core equipment for fertilizer manufacturing process. As one of leading fertilizer machine manufacturers in China, in addition to the disc granulator, we also produce other types of fertilizer granulator machines, and other equipment such as compost turning machines, mixer machine, crusher machine, etc.

Bio-organic fertilizer refers to a kind of fertilizer with microbial fertilizer and organic fertilizer effect, which is composed of animal manure as the main raw material, inoculated with microbial compound microbial agent, fermented and decomposed to completely kill pathogens, insects and eggs, etc. Biofertilizers generally contain a large number of elements such as nitrogen, phosphorus and potassium, and trace elements such as calcium, magnesium, sulfur, iron and boron, as well as a large number of organic and humic acid substances, so that the fertilizer supply is balanced. The bio-organic fertilizer production line processes the fermented materials into the final organic fertilizer.

Raw materials for organic fertilizer production equipment

The main raw materials for biofertilizer production are livestock manure, crop straw and other agricultural wastes.

Mixed ingredients for organic fertilizer production

The source of raw materials, fermentation methods and equipment are different, and the ingredients are different. The specific formula depends on the source of organic materials. The general principle of proportioning is that the content of organic matter in the total material should be more than 30% (50% – 70% is the best), the ratio of carbon to nitrogen (15:1) – (20:1), the pH value should be 6-7.5, the moisture content should be about 50%, and the water content should be adjusted to 50% – 70% when inoculated.

Fermented maturity

It can be stacked flat or fermented in a fermentation tank. Fermentation tanks are usually placed in closed or semi-closed fermentation chambers. The effect is better than that on flat ground. It needs to be turned periodically by the fertilizer turner machine every three days. After 25-30 days of fermentation, the temperature gradually decreases from 70-80℃ to stable, and the decomposition is completed.

How to choose fertilizer manufacturing process plant

fertilizer granulator Nov 12, 2019

Fertilizer promotes the development of ecological agriculture, and the demand is huge. Investment in building fertilizer plants has become a popular project. Some investors want to build small-scale fertilizer manufacturing process to save costs, while some investors in fertilizer plants are going to build large-scale fertilizer plants to save unit production costs.

So what should we pay attention to when purchasing fertilizer manufacturing process plant? Here are some notes.

1. Determine the type of fertilizer and producton site. Determining whether to produce organic fertilizer or compound fertilizer affects the choice of site. If organic fertilizer is produced, it should not be too far from the farm where raw materials are provided. The type of fertilizer determines whether compound fertilizer equipment or organic fertilizer equipment is needed. Different types of fertilizer equipment also have differences.

2. Determine the fertilizer granulator machine. Granulation is the key link in fertilizer production and plays an important role in the quality of manufactured fertilizer. Fertilizer granules are cylindrical, spherical and flat spherical in shape. The granules produced by granulators of different shapes are different. The choice of granulator is related to the scale of fertilizer plant construction and local market. Fertilizer factories have different investment scales, different production processes, and different supporting equipment.

If a small fertilizer plant is to be built, it is suggested to configure simple machinery and equipment to reduce investment in equipment. The small fertilizer production line is composed of crusher, mixer, granulator, drum screener and automatic packing machine. If organic fertilizer fermentation is needed, it can be carried out with batten fermentation and windrow turning machine. The advantages are that they are more in line with the principle of aerobic fermentation. It is not easy to form anaerobic fermentation. The fermentation is full and complete, and the fermentation speed is fast. Forklift trucks can also be used instead of turner (the effect is not as good as turner), which can be adopted in terms of saving investment. According to the local environmental protection requirements, choose dust removal settings, where environmental protection requirements are high, choose heavy dust settings to meet the local emission quality standards.

Investment in large and medium-sized fertilizer plants, fertilizer production equipment can choose turning machine, automatic batching system, loader feeding hopper, crusher, mixer, granulator, dryer, hot stove, cooler, feeder, screener, cyclone dust collector, packing machine, etc. Increase mechanical automation, save manpower and cost. Organic fertilizer tank fermentation, can choose simple compost turning machine, double screws compost turning machine (suitable for large yield).

3. Determine the manufacturer of fertilizer manufacturing process plant. Several fertilizer machine manufacturers were inspected, and the strength, scale and reputation of the manufacturer of fertilizer equipment were fully understood. It is better to inspect the production workshop, finishing workshop and assembly workshop of the enterprise, to know the product quality, processing equipment, production process of the enterprise, and whether the fertilizer equipment produced by the manufacturer is professional. Referring to the customer cases that the manufacturer has completed, on-site test machine, the production site can best show the real operation of the equipment. Looking for fertilizer equipment suppliers with perfect after-sales service, suppliers provide professional technicians to guide customers to install and debug equipment, so that the equipment can operate normally, and provide corresponding training services.

4. Determine the safety performance of fertilizer manufacturing process plant. Safety is the first, before purchasing, we need to consider whether the production line has safety devices, whether the machine design is reasonable, whether safety factors are taken into account, whether the parts are not welded properly, whether the bolts are tightened, whether there is pollution, and so on. In addition, whether the overall operation of the equipment is smooth and whether the design of the production line is reasonable are also matters needing attention, because it relates to the efficiency and quality of the operation of the equipment. With the permission of the manufacturer, the operator can try to operate it in practice and feel its state conveniently.

How to maintain fertilizer manufacturing equipment

fertilizer granulator Nov 12, 2019

Fertilizer equipment is an important tools for fertilizer manufacturing process. Fertilizers processed by fertilizer equipment have abundant and diverse nutrients, which are rich in materials needed by vegetation and can meet the needs of various nutrients for crop growth. After fertilizer equipment is put into production, attention should also be paid to maintenance and maintenance, not just production. Running the equipment according to usage standard to produce fertilizer, check regularly to ensure normal operation, so that the service life of the equipment is longer. Following are some techniques for maintaining fertilizer equipment.

1. Bearings in fertilizer production equipment bear all the loads of the machine, so good lubrication has a great relationship with bearing life. The use of bearings affects the service life and operation rate of the machine. Therefore, it is recommended that bearings be inspected once every 7 days and lubricating oil be injected into them regularly.

2. Check the machine of the whole fertilizer production line regularly, and pay attention to whether the work of each part of the fertilizer granulator machineis normal. The wear level of vulnerable parts should be checked, such as cleaning the chain every 3 days, and replacing the worn parts in time.

3. If there is a fault in the running of the rotating gear, stop immediately to check and eliminate it.

4. The chassis of fertilizer production equipment should be placed smoothly to remove dust and other impurities, so as to avoid special circumstances and serious accidents in the production of machinery.

It is suggested that fertilizer factories should do the following for fertilizer manufacturing process:

1) Improve the maintenance system and eliminate hidden dangers. When the fertilizer production line is put into production, it is necessary to formulate rules for the use of various machines and maintenance systems. Operators can operate and maintain according to the regulations, so as to prevent safety accidents and avoid unnecessary failures of machines. For example, when workers clean and maintain the machine, they can find out the problems existing in the machine and check them in time to avoid greater losses.

2) Maintenance of the machine should be carefully and in place. Whether a fertilizer production line can operate efficiently and normally and give full play to its performance is not only related to the quality of the equipment itself, but also to the correct use and proper maintenance of the operators. Maintenance of the machine is troublesome, but if not done, it will affect the production of equipment products, maintenance costs and replacement costs of vulnerable parts will continue to increase.

3) It is necessary to assign responsibility, check and record every day, lubricate and maintain the important parts of the equipment (vulnerable parts, motors, reducers, bearings, etc.) according to the instructions before leaving work every day. If there is any damage, it should be replaced or repaired in time to avoid affecting the normal production the next day.

4) The cause of equipment failure should be analyzed in time and lessons learned. The reason for the failure of fertilizer equipment may be the failure of the machine itself, or the improper operation and maintenance, etc. Once the fertilizer equipment fails, we should analyze the causes of the problems, take measures to learn lessons and prevent similar situations from happening again.

Detailed explanation of the working principle of compound fertilizer equipment

Zhengzhou Tianci Machinery specializes in the production of compound fertilizer equipment. The following is a detailed introduction to the working process of the NPK fertilizer production line and the mechanical equipment used. Hope to help you.

The following is detailed description:
1. Selection of raw materials: According to the formula operation, add additives, trace elements, N, P, K, etc. to the mixer machine for mixing. The advantage of alternate mixing with two compound fertilizer equipment is: continuous production, improved efficiency, greatly Reduce the labor intensity of people.

2. Mixing raw materials and ingredients: mixing and pulverizing with a horizontal pulverizer unique to the compounding equipment, the pulverizer can thoroughly pulverize the added bulk materials, so that the raw materials are completely mixed.

3. Granulation: Granulation is a very important step in the NPK fertilizer production line. There are also many kinds of fertilizer granulator machine. The specific classifications are: drum granulator, disc granulator, extrusion granulator, and these three granulators are the most widely used in the NPK fertilizer production.

4. Drying the granules to increase the hardness: The granulated compound fertilizer has formed granules, but since there is still moisture and the hardness does not meet the requirements, it must be dried.

5. Cooling granules: The dried granules are transferred to a cooling machine for cooling to a normal temperature, which further increases the strength of the composite fertilizer granules and further reduces the moisture.

6. Screening: After cooling, the composite fertilizer particles will have powdery particles. The fine powder and large particles will be completely sieved out by the sieving machine. The fine powder will be directly returned to the mixer and mixed with the raw materials through the return belt conveyor, and then participate in the granulation process again. After the large particles are pulverized, the fine powder is returned to the mixer through the same return belt conveyor.

7. Packing: Packing with packaging machine. After the worker puts on the bag and triggers the switch, the packaging machine automatically completes the bag, blanks and bags. At the same time, the feeding device is automatically and automatically fed. When the weighing weight of the weighing system reaches the set value, the feeding is automatically ended, and the operator puts on a new packaging bag for the next packaging process.
