fertilizer granulator Dec 29, 2022

Bucket elevator is used as the conveying equipment of organic fertilizer production line and npk blended fertilizer. How to deal with failures in the application process?

1. Aiming at the chain hook fracture problem of bucket elevator, the staff should lengthen the distance of the chain hook wire during maintenance, and add a reinforced base plate at the fixed part of the chain hook when installing the hopper, and weld the two parts together, so as to form a relatively complete chain link. This can not only reduce the occurrence of the chain hook fracture to a great extent, but also improve the safety One step to ensure the strength of the chain hook.

2. In view of the situation of the upper sprocket slipping, before NPK production line work, the relevant staff must check the situation of the sprocket of the elevator, and try to use the anti-skid sprocket as far as possible. The upper sprocket can be processed to form a chain nest shape, which can greatly reduce the occurrence of the sprocket slipping, and the transmission efficiency of the bucket elevator can also be effectively improved .

3. The bucket elevator transports the granules formed by the fertilizer granulator. In view of the situation that the materials stick to the wall in the bucket elevator shell, the shell situation must be fully considered when selecting the conveyor.

How to select appropriate equipment manufacturers for NPK fertilizer production line

fertilizer granulator Dec 29, 2022

With the development of chemical fertilizer industry, NPK fertilizer equipment industry has developed rapidly in recent years, which has driven the development of the industry to a certain extent. NPK production line has been developing steadily. At present, the technological level of the world is to promote the development of numerical control technology by production as the mainstream, and the future development will be the same.

On the basis of further improving precision, efficiency, automation, intelligence and networking, our factory has gradually transformed fertilizer equipment into processing unit and cutting-edge flexible manufacturing system. At present, the fertilizer production equipment industry has entered the stage of scientific development and technology first, China’s international influence continues to heat up, and the industrial technology level is further improved. As our products are closely linked with strategic new industries, with the advantages of high efficiency, energy saving and high cost performance, our exports to developed countries are mainly at the middle and low end, and this part of consumer demand is rigid. Therefore, there is still a large market space for the development of fertilizer equipment industry.

Facing the huge demand of agricultural development, fertilizer granulator equipment manufacturers have the responsibility to continuously develop products with better quality, lower price and more suitable for recycling. If we want to process fertilizer into high quality commercial fertilizer, we must carry out granulation.

Our granulation equipment includes disc granulator, rotary drum granulator and roller extrusion granulator. Because different organic fertilizer components are different, the organic fertilizer particles produced are different, and different soil requires different fertilizer particle size. Granulator solves this problem, and can produce organic fertilizer with different particle size and shape according to different needs.

Model Selection of Organic Fertilizer Granulator

fertilizer granulator Dec 29, 2022

The difference in the selection of organic fertilizer granulator models lies in the selection of appropriate granulation methods according to the use requirements of materials. This is just a big general term. There are subdivisions and branches under it. It is mainly divided into dry method and wet method:

Dry process mainly refers to products with relatively low water content. Generally, water content below 10% is a zero limit. (There are also few materials that can reach 16%, for example, some materials only carry crystal water.) Most of the particles produced by dry granulation are irregular particles (for example, ordinary granular potassium fertilizer) or the more common shape is similar to small gravel. With the current industrial upgrading and increasingly strict environmental protection requirements in China, many chemicals and building materials need granulation.

The main index of wet granulation is the material with a water content of more than 20%. There are various equipment and methods for wet granulation. For example, disc granulation, drum granulation and spiral granulation have been carried forward many years ago, and have been greatly improved by increasing the use environment and processing requirements of different materials. For example, the particle size of relatively popular organic fertilizers over the years ranges from 1mm to 6mm. These methods were adopted.

Compared with wet granulation, dry granulation in organic fertilizer granulator consumes less energy, is more environmentally friendly, does not require drying, does not add water and binder, and does not change the properties of materials; Compared with wet granulation, these are also several advantages of dry granulation. It is more suitable for industrial production.

In another case, some materials require relatively small particle sizes. Products between dozens of meshes and 100 meshes can also be reduced by airflow, spray and rapid drying.

Equipment and technology of packaging machine in npk fertilizer production line

fertilizer granulator Dec 29, 2022

Automatic packaging machine is an indispensable production equipment of NPK production line, which improves the efficiency of the whole production process.

Innovation is an important part of the development of automatic fertilizer packaging machine. Although there are many kinds of automatic fertilizer packaging machines, most of them are semi-automatic operation. They only carry out targeted bagging and sewing. The packaging method is relatively single and lack of innovative elements. If we don’t pay attention to the renewal of packaging machine technology, the enterprise will be eliminated in the saturated automatic packaging machine market in the future.

Fertilizer automatic packing machine

Automation and intelligence of mechanical equipment is always the direction of its development. Only by constantly innovating and adapting to the needs of the market, can the packaging industry walk out of a new production road. In addition, the technological innovation and upgrading of fertilizer packaging machinery will become a powerful boost to the development of enterprises, and the fertilizer automatic packaging machine, which starts to develop in the direction of diversification, will change the traditional production mode and will develop rapidly. In the fertilizer production industry, the granules produced by the organic fertilizer granulator machine are quantitatively packed in the flow industry.

Through the continuous use of high technology, the position of the automatic packaging machine in the market is becoming more and more stable, and at the same time, its development is opened. Continuously through the improvement of technology, it not only guarantees the efficiency and quality of product packaging production, but also makes it easier to expand into new markets. , To open a new field of development for it. At present, it has been imitated by many companies, but it is still unable to surpass in terms of corporate image and after-sales service, forming a situation where the packaging machine market is uneven and mixed.

We also need to know that the success of the automatic quantitative packaging machine comes from the perfect application of science and technology, and the automatic packaging machine is fully used in the fertilizer production line. In order to maintain its market position, manufacturers of automatic fertilizer packaging machines must carry out the application of science and technology to the end and continuously improve the independent innovation capabilities of core technical personnel.

Ventilation and oxygen supply are the key factors for successful composting of organic fertilizer composters.

fertilizer granulator Dec 26, 2022

The oxygen consumption of compost is related to the content of organic matter in compost raw materials. The more organic carbon in compost materials, the greater the oxygen consumption. The suitable oxygen concentration of raw materials for chicken manure organic fertilizer production enterprises in the composting process is 18%. When the oxygen concentration is lower than 18%, the life activities of microorganisms in the good composting process are limited, which is easy to make the compost enter the anaerobic state and produce odor.

Many customers are concerned about whether the materials in the production of organic fertilizer will corrode the organic fertilizer peripheral equipment. If the material corrodes the machine, the service life of the turnover machine and equipment will be shortened, and the production cost of organic fertilizer will increase, which is not a cost-effective investment for enterprises.

However, the manufacturer of the organic fertilizer turnner clearly told everyone here that the production of organic fertilizer would not cause corrosion to the tipper. If it is not used for a long time, the equipment needs to be thoroughly cleaned, otherwise it will cause corrosion to the machine. This is because if the machine is not used for a long time, the residual substances in the machine will combine with the water molecules in the air to form a large amount of water, and the contact parts will be corroded after a long time of contact with the machine, but this will not happen in the normal production cycle.

Advantages of granulator widely used in organic fertilizer production

fertilizer granulator Dec 26, 2022

Organic fertilizer granulator is a kind of equipment for producing organic fertilizer, which is widely used in organic fertilizer production. Most of it is used in good farmland, fruits, vegetables, etc., which is conducive to environmental protection. However, the noise of the organic fertilizer granulator is very loud in the work, which also affects the hearing of the operator and brings great trouble to people. Today, we shared the advantages of organic fertilizer granulator and the methods to control noise.

Advantages of organic fertilizer granulator

After the pressure wheel of organic fertilizer granulator increases, the bearing increases and the bearing capacity increases.
With the increase of the pressing wheel, the temperature generated by the extrusion friction is not easy to transfer to the bearing cavity, thus ensuring that the low temperature lubricating oil of the bearing is not easy to overflow.

After adding the roller, the roller can be pressed for 2-3 times, extending the service life of the organic fertilizer granulator, reducing the production cost, and increasing the profit margin of the investment project.

This type of press adopts a variety of uniform distribution, which ensures stable operation, increases the pressing area and improves the production efficiency.
The molding of this model is diversified. As long as the round bar and particles are replaced to adapt to the compression molding of different materials, the round bar and particles can be molded.
Machine fertilizer granulatoris used for granulation in the following range:

The main results are as follows: (1) Bioorganic fertilizer granulation was carried out with peat, lignite, organic fertilizer sludge and straw as raw materials.

(2) Granulation of organic fertilizer with chicken manure and other organic fertilizers as main raw materials.

(3) Cake fertilizer mainly made of soybean cake.

(4) Full price feed and mixed feed with corn, beans and grass flour as raw materials.

(5) Granulation of bio feed straw with crop straw as raw material.

Screening and Beating of Drum Screen in Fertilizer Production Line

fertilizer granulator Dec 26, 2022

Fertilizer equipment drum screener machine is divided into ordinary screening machine, automatic beating device screening machine. According to the general screening equipment, we specially designed the drum screening machine, which has small screening resistance, small power and standard thickness steel plate. The designed dust cover can remove the powder dust, improve the working environment and protect the environment. This kind of fertilizer equipment after-sale maintenance is simple and convenient, only need to replace the screen.

1. Fertilizer drum screener machine is mainly composed of motor, reducer, drum device, frame, sealing cover, inlet and outlet. The whole is inclined to the ground surface, and the outside is sealed by a sealed isolation cover to prevent environmental pollution. The screening drum is rotated at a certain speed by the variable speed deceleration system. The granular materials formed by the rotary drum granulator are separated from top to bottom through the screening drum. The fine materials are discharged from the lower part of the front end of the screening drum, and the coarse materials are discharged from the lower part of the screening drum.

2. The drum screening machine can be equipped with an automatic flapping device. During the screening process, the relative movement of the flapping device and the screening drum can achieve uninterrupted cleaning of the screen body, so that the screening drum can always be kept clean and clean during the entire working process. No sticking, no blocking, and no influence on the screening effect. After the granules made by the organic fertilizer granulator machine enter the drum, they are screened as the drum rotates. On the one hand, large-size particles flow forward along the slope of the drum, and are gradually screened out through screens of different meshes. After small materials are screened out, the powder enters the granulation equipment again for granulation.

No matter we process powder fertilizer or granular fertilizer, we have to use drum screening machine, which is an important part of NPK production line. How to place the vertical screening machine on the production line to save the floor space? How much is a drum screen? For specific questions about screening equipment, please contact us.
