Process of organic fertilizer production line for sludge and feces treatment

fertilizer granulator Dec 14, 2022

Fertilizer based on waste and bio organic residues. Its types are: domestic garbage; Domestic sewage; Abattoir waste; Marine fertilizer (local fertilizer consisting of animals, plants or minerals in coastal areas). Organic fertilizer contains a large amount of nutrients required by plants, providing a mild and lasting nutrient supply for plants, and has long-term aftereffects. Organic fertilizer also contains a variety of trace elements. Because all kinds of nutrient elements in organic fertilizer are complete, and these substances are completely non-toxic, harmless and pollution-free natural substances, this provides the necessary conditions for the production of high-yield, high-quality, pollution-free green food. Organic fertilizer contains many kinds of sugars, and the application of organic fertilizer increases many kinds of sugars in the soil. With the large amount of energy released by the degradation of sugar and organic matter, there is energy for the growth, development and reproduction of soil microorganisms.

Application Experience of the Double roll Extrusion Granulator for Organic Fertilizer

fertilizer granulator Dec 14, 2022

The double roll extruding granulator is a granulation process that uses the strong pressure of the equipment to make the solid materials get together. This granulation discharge does not need to pass through the boring process. The counter roll extruding granulator kneads the materials by two counter rotating rollers. When the solid materials are subjected to the external force of the extruding granulator, the air between the powder particles shall be removed first to make them rearrange, so as to eliminate the space between the materials. When the material is kneaded by the extruding granulator, the particles will deform or move, and a strong van der Waals gravitational recombination will occur. At the end of the kneading and granulation process, the energy that forms the system energy with pressure will form a hot spot at the contact point between ions, but the material will melt. The temperature drop and the cooling of the material after discharging will form a fixed and undeformed particle.

During the early operation of the counter roll extruding granulator and other granulating equipment, attention must be paid to the feeding. The usual materials are transported to the bin of the counter roll extruding granulator through the screw conveyor after being damaged by the hammer crusher. It is necessary to ensure the smooth transportation of materials. If the load is not too high, the motor will be overloaded or the machine will be directly supported.

How to Reduce Noise of Organic Fertilizer Dryer

fertilizer granulator Dec 14, 2022

With the wide application of organic fertilizer dryer equipment, many customers reported that after using the organic fertilizer dryer equipment for a period of time, it will produce strong vibration and noise, which will do great harm to operators and the surrounding environment. As the manufacturer of organic fertilizer dryer equipment, here we take the rotary dryer as an example to introduce several good methods to effectively reduce noise.

1. Add sound insulation cover. The whole rotary dryer is closed with steel structure skeleton, thin steel plate as shell, damping layer plastered inside and filled with ultra-fine glass wool or other sound absorbing materials. As the rotary dryer generates a lot of heat during operation, attention must be paid to solving the problems of heat dissipation in the hood and facilitating equipment maintenance.
2. The noise level can be reduced by 9dB (A) if the manganese steel lining plate is replaced by the rubber lining plate, and the frequency spectrum characteristics also change from high frequency to low frequency.
3. Set the elastic layer. A heat-resistant soft rubber pad is laid between the inner surface of the drum of the rotary dryer and the lining plate. In order to prevent the soft rubber pad from overheating, an industrial felt with a thickness of 10-15mm is laid between the lining plate of the dryer and the soft rubber pad, which can reduce the noise of the rotary dryer below the standard.
4. Wrap the sound insulation layer outside the drum wall. Wrap a layer of 50mm thick industrial felt outside the drum wall of the rotary dryer, use the 1. smm thick steel plate as the protective surface, and fix it on the drum wall with bolts. The actual sound insulation value is about 12dB (A). If the two ends of the drum are also treated in the same way, the joint of the drum wall binding shall be well sealed, and the sound insulation effect may also be improved.
5. Sound insulation room is designed. If conditions permit, therotary dryerroom will be transformed into a special sound insulation room, which will be better than the sound insulation cover. However, attention must be paid to solving the problems of monitoring, indoor heat dissipation and maintenance during the operation of the rotary dryer.

Effect of Material Moisture on Organic Fertilizer Granulator

fertilizer granulator Dec 14, 2022

In the production process of organic fertilizer granulator, the raw materials are required to have a certain viscosity. Some raw materials are relatively loose after fermentation and are not easy to granulate. A certain amount of water or adhesive needs to be added to improve the viscosity of materials. The disc granulator and raw meal granulator of organic fertilizer equipment adopt the granulation method, and water or adhesive is added in the granulation process to ensure the smooth granulation of materials. The new organic fertilizer granulator adopts wet granulation, and the fermented materials can be directly granulated without other process operations. The double roller extruding granulator is a non drilling room temperature granulator suitable for granulation of materials with low viscosity and low moisture content.

If the water content of the material is too high, some dry materials can be added appropriately to neutralize the water. If the water content is too low, an appropriate amount of water can be added to facilitate granulation.

The new organic fertilizer granulator is a kind of organic fertilizer granulator that is constantly updated and transformed with the development of agriculture, the improvement of technology and the diversification of demand. The new organic fertilizer wet granulator can realize the material selection, as long as all kinds of organic matter after effective fermentation can be granulated through the new organic fertilizer granulator, breaking the limitations and obstacles of the traditional process. Before granulation, there is no need to stop the processing of raw materials, crushing and drilling tasks. Therefore, batching processing and direct granulation can be realized directly, which not only saves a small amount of power investment and effectively reduces the cost, but also improves the task efficiency, which is convenient, fast and satisfactory.

Maintenance of chain type organic fertilizer crusher

fertilizer granulator Dec 14, 2022

First, do a good job in thermal insulation The climate and environment make the transmission parts of various parts start slowly or fail to start due to freezing, which requires that the workplace of the chain type organic fertilizer crusher or the chain type organic fertilizer crusher itself must have certain thermal insulation measures. The raw materials used for the operation of the chain type organic fertilizer crusher must also be subject to antifreeze treatment The moisture of organic fertilizer raw materials is too high, and antifreeze treatment is also critical for the use of organic fertilizer granulator in winter.

Second, use special lubricating oil Low temperature and frequency of use may cause the lubricating oil to encounter freezing and retention, which will affect the lubricating oil supply of the chain type organic fertilizer crusher. Timely adding lubricating oil to this popular chain type organic fertilizer crusher can maintain better use effect.

Third, reasonable maintenance After each work, the chain type organic fertilizer crusher must be checked and maintained, mainly focusing on the drive part, lubrication part and residual material cleaning. The maintenance is the basis for the use of the chain type organic fertilizer crusher in winter In addition, the failed parts of the organic fertilizer chain crusher shall be replaced in time to avoid the operation of the organic fertilizer chain crusher with problems, reduce the production and use costs caused by the machine failure, and the reasonable maintenance shall also be completed regularly to ensure the maintenance and attention of each component in order to make the organic fertilizer chain crusher show a better effect.

Improve the working efficiency of organic fertilizer crusher

1. The selection of materials is the key. When selecting materials, pay attention to the hardness of materials. The harder the material is, the more difficult the equipment is to crush and wear. The crushing speed is slow and the natural crushing capacity is small.

2. The humidity of the material is the key. When the water content of the material is large, the material is easy to stick in the grinder, but it is also easy to block during the feeding process, thus reducing the crushing capacity. Therefore, the water content should be reduced as much as possible before crushing so that the grinder can operate better.

3. Crushing materials require high fineness, that is, the finer the material, the smaller the crushing capacity.

4. Composition of crushing materials: The more fine powder content in the materials before crushing, the greater the impact on crushing, because these fine particles are easy to adhere and affect transportation. The content of fines shall be pre screened.

5. Viscosity of materials: that is, the greater the viscosity of materials, the easier the bonding.

6. The better the abrasion resistance of the crushing parts (hammers and jaw plates) of the crushing equipment, the stronger the crushing capacity. If they are not abrasion resistant, the crushing capacity will be affected. For example, crushed straw can be made into organic fertilizer, which can destroy farmland and greatly improve the use efficiency based on farmland.

Benefits of organic fertilizer on agricultural production

fertilizer granulator Dec 14, 2022

Organic fertilizer is made from livestock manure, straw and other raw materials through fermentation and decomposition of beneficial microorganisms. The direct use of non rotting organic substances will cause serious problems, such as root burning, chicken pox and other diseases, which will seriously affect the quality and efficiency of fruits. The process of fermentation and decomposition is mainly through the high-temperature aerobic fermentation of microorganisms (the decomposition temperature can reach more than 80 ℃), harmless, stable and deodorized substances to form organic fertilizers, which are conducive to the growth and development of fruit trees and improve the soil.

Organic fertilizer is a kind of organic fertilizer and a certain number of functional microorganisms. After the impurities in livestock manure, crop straw, agricultural and food processing products and organic wastes are treated, it is combined with multifunctional fermentation seed agent, rapid deodorization, maturation and dehydration, and then added with functional biological seed agent for treatment. It meets the chemical fertilizer principle requirements for the production of safe and pollution-free green agricultural products, and is a promising fertilizer. When applying bio organic fertilizer to vegetables, we must master the correct fertilization method to obtain good fertilization effect.

There are two types of machines that you can obtain for producing dry chicken manure pellets. This will include a flat die granulator and a double roller granulating machine. A flat die granulator is a self-contained machine that can be positioned in any indoor facility. The manure is added to the top, and the pellets are produced by compressing the material from up above. A double roller granulator is a machine that can produce pellets by rolling two separate rollers that come together. The pellets will be made, and will be dropped out at the bottom. Once they are dry, you can package them, or you can simply use them on your crops.

Reasonable ratio of raw materials is the basis to improve the ball formation rate

fertilizer granulator Jan 5, 2021

Single chemical fertilizer can not meet the needs of various nutrients of plants. NPK fertilizer production line mixes and granulates different nutrients to improve fertilizer efficiency. So how to improve the pelletizing rate of fertilizer?

1. Reasonable match of fineness of raw materials. According to our experience, the fineness of the whole raw material should be matched as follows: about 30% – 40% of the raw materials with 100-60 mesh, about 35% of the raw materials with 60 mesh to 1.00mm diameter, and about 25% – 30% of the small particles with 1.00-2.00mm diameter. The higher the fineness of the material, the better the viscosity, and the higher the surface finish of the granulated particles. However, in the production process, the proportion of high fineness materials is too high, and it is easy to cause the bad problems such as too large particles, irregular particles and material wall sticking due to the good viscosity.

2. The reasonable collocation of cohesive material and dispersive material. In the production process formula, the proportion of viscous raw materials is high, the organic fertilizer granulator is easy to form balls, the proportion of dispersive raw materials is high, and there are more fine powders. In the conventional formula, the proportion of low concentration compound fertilizer viscosity raw material is 45% – 50%, and the proportion of high concentration compound fertilizer viscosity raw material is 35% – 40%. At the same time, it should be combined with material fineness. With bad matching, there will be no fine powder, no particles, particles are not round, easy to get big balls and other problems in the production process.

3. The chemical reaction between materials should be considered when formulating. After the formulation of some materials, free water will be precipitated during the production process, which will cause the liquid phase of the material to exceed the standard and cannot be produced normally. After matching, some raw materials will greatly reduce the critical relative humidity of the mixture. During the process of organic fertilizer production equipment, due to the large amount of moisture absorption Unable to produce normally. Therefore, the chemical reaction between the materials must be considered when formulating to achieve a reasonable match between the materials.

4. Comprehensive water content of the material after mixing. The water content of the raw materials directly affects the pelletizing effect of the disc granulator machine. Some materials are stirred into mud without steam and water in the production, resulting in the failure of normal production. Therefore, keeping a low water content of the material is conducive to the addition of steam in the granulation, to the improvement of the temperature and viscosity of the material, so as to improve the compatibility between the materials and the balling rate.
