Advantages of granulator widely used in organic fertilizer production

Written by fertilizer production line on December 26th, 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.

Main purpose of producing organic fertilizer double roller granulator

Screening and Beating of Drum Screen in Fertilizer Production Line

Written by fertilizer production line on December 26th, 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.

Reasons for using livestock manure to produce organic fertilizer in agriculture

Written by fertilizer production line on December 26th, 2022.

With the continuous popularization of organic fertilizer, more and more people begin to use organic fertilizer for production and planting. There are many raw materials for producing organic fertilizer, but many double roller granulator use manure to produce organic fertilizer.

The green, ecological and sustainable development of the circular economy of the double roller granulator not only ensures food safety, but also solves the environmental pollution caused by feces. Moisture control of organic fertilizer fermentation: 65% of organic fertilizer fermentation moisture, how to judge the moisture content? Grasp a handful of materials with your hand, you can see the watermark on your finger, but it will not drip, it will fall to the ground and spread. High water content will lead to poor ventilation, slow temperature rise and unpleasant smell. High water content can be obtained by adding straw, sawdust and mushroom residue. When the water content is too low, the fermentation is slow. When the water content is too low, the manure or water separated by the solid-liquid separator can be used to ensure the water content.

Animal manure processing equipment can process animal manure into organic fertilizer in a short time, so it is also called organic fertilizer production equipment. When the equipment system is working, the feces of livestock and ingredients are sent to the mixing mixer according to the specified proportion for mixing and mixing to make it uniform. The mixture is further mixed by the screw conveyor and sent to the host pressurized mixer. The temperature of the mixture in the machine is raised by the pressure friction of the pressurized mixer, killing or inhibiting low-temperature bacteria, killing ascaris eggs and harmful bacteria, and then providing appropriate air and water, Create suitable conditions for thermophilic bacteria fermentation, complete the rapid fermentation, then crush and loosen it through a grinder, and finally send it to the storage yard for stacking to become organic fertilizer.

Noise reduction method of organic fertilizer granulator

Written by fertilizer production line on December 26th, 2022.

There may be a problem with the bearing of a part of thegranulator, which makes the machine work abnormally, the working current fluctuates, and the working current is high.
The annular die is blocked, or part of the die hole is separated from the material. If the annular die gets into foreign matters, the annular die will break away from the circle, the clearance between the roller and the die is too tight, the roller is worn or the roller bearing is damaged and cannot rotate, which will cause the vibration of the granulator.
The alignment of the coupling is unbalanced, the height and height have deviations, thegranulatorhas vibration, and the gear shaft oil seal is easy to be damaged.
The main shaft is not tightened, especially for D or E machines. The looseness of the main shaft will cause axial movement before and after the movement. The roller swings obviously, and the granulator is noisy and difficult to granulate.
The wear of big gear and small gear, or the replacement of single gear, will also produce a lot of noise.
The discharge of materials at the outlet of the conditioning device is uneven, which makes the working current of the granulator fluctuate greatly.
The new ring die must be used to prepare the new drum, and a certain proportion of sand bran must be used for grinding and polishing.
The tail of the hair conditioner is not fixed or fixed, and will not shake.

Fermentation function of bio organic fertilizer tipping machine

Written by fertilizer production line on December 26th, 2022.

Composting is a process in which organic matter is continuously degraded and stabilized under certain conditions through the action of microorganisms, and produces a product suitable for land use. Under the action of microorganisms, the organic fertilizer composter will make various organic substances in the composting process difficult to decompose, stable and easy to be absorbed by crops.

Inoculum. Adding microbial agents (microbial agents) to livestock manure can speed up the fermentation of compost. Adding stable fertilizer with good decomposability or compost with 10% – 20% of raw materials can speed up fermentation. During composting, microbial communities are formed in a natural way and participate in the fermentation of organic wastes and the decomposition of humus compounds.

The size of the compost material. With the movement of microorganisms on the surface of organic particles, reducing particle size and increasing surface area will promote microbial activity and accelerate composting. On the other hand, if the raw materials of the chicken manure organic fertilizer plant are too thin, it will hinder the air flow in the pile layer, reduce the amount of oxygen available in the pile layer, and then slow down the activity of microorganisms. Therefore, in order to speed up the fermentation process, it is necessary to minimize the particle size of composting materials on the premise of ensuring air permeability. Livestock manure is a kind of thick paste, which usually requires adding a lot of materials to increase the porosity.

PH is also one of the important factors affecting the growth of microorganisms. Generally speaking, the pH value most suitable for microorganisms is neutral or weakly alkaline. High or low pH makes composting difficult. In addition, pH also affects nitrogen loss, so when pH is higher than 7.0, nitrogen will volatilize in the form of ammonia. However, generally speaking, the pH of livestock manure can meet the requirements of fermentation.

Trouble shooting of bucket elevator in operation of NPK fertilizer production line

Written by fertilizer production line on December 26th, 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.
