Solutions to problems in npk fertilizer production line

fertilizer granulator Dec 19, 2022

 In the process of using NPK production line equipment, there may be a variety of problems. These problems are actually normal phenomena. We should solve the problem in time so as not to affect our work. So, how can we solve the common problems in the production of fertilizer equipment?

When using NPK production line equipment, if the motor overheats and the sound is abnormal, what should be done? This kind of problem usually occurs. We must first consider the following matters:

1. Poor lubrication or serious wear of rotary drum granulator bearing;

2. Poor contact or single-phase separation of switch circuit;

3. Is the voltage too low? If the sound of the pellet firearm is abnormal during the operation, the drum will be blocked by obstacles, or even not rotate, and the bottom box may vibrate.

The reason for the above phenomenon is usually caused by the objects in the fertilizer granulator, and then the granular material falls off, the machine bulges, and the equipment is worn out in severe cases. At this time, maintenance and troubleshooting must be carried out. In addition, the reducer of some organic fertilizer equipment overheated due to lack of oil or poor oil quality. Excessive wear or improper meshing of gears and worms, poor lubrication of bearings or severe wear. The weakening of the magnetic field strength of the fertilizer equipment is usually due to the high temperature. If the temperature is too high, the temperature will rise.

This is the cause of common failures and quick cleaning methods when users use fertilizer granulator equipment. If the fertilizer production line equipment fails, don’t panic. First, find out the problem to make maintenance easier. We usually focus more on maintenance and extend the life of organic fertilizer equipment.

How to deal with the caking problem in the organic fertilizer production line

fertilizer granulator Dec 19, 2022

How to solve the problem of organic fertilizer caking has always been a problem for users. The problem of organic fertilizer caking generally occurs in the process of fertilizer processing, storage and transportation. Zhengzhou Tianci Heavy Industry Machinery Co., Ltd. answers this problem in detail to you.

1. Organic fertilizer caking is mainly caused by moisture absorption of micro fertilizer grains, surface dissolution (deliquescence) evaporation and recrystallization. In this process, crystal bridges are formed, resulting in small particles becoming large particles and caking. The caking problem is mainly related to materials (raw materials for fertilizer production), humidity and temperature, small livestock and poultry organic fertilizer production line, external pressure and storage time.

2. The fertilizer production of the organic fertilizer production line is generally non closed production. In the production process, the higher the air humidity is, the easier the fertilizer will absorb moisture and agglomerate. When the weather is dry or the raw materials are dried, the fertilizer is not easy to agglomerate. The higher the room temperature of the extruder granulator is, the easier it is to dissolve. Generally, the raw materials are dissolved in their own crystal water and lead to agglomerate. When the nitrogen temperature is higher, the water evaporates and is not easy to agglomerate.

3. The temperature is generally above 50 ℃, and we usually need to heat to reach this temperature. The greater the external pressure of the fertilizer granulator on the fertilizer, the easier the contact between the crystal and the easier the caking; the smaller the external pressure, the less easy the caking, the longer the placement time of the produced fertilizer, the easier the caking, and the shorter the placement time, the less easy the caking.

Zhengzhou Tianci Heavy Industry Machinery Co., Ltd. adheres to the concept of “honest operation, attentive service” to provide you with high-quality products and services, with an annual output of 1-200000 tons. The local resources, market capacity and market coverage should be taken into account in the production of organic fertilizer. The investment scale and product scheme design of organic fertilizer production line need to be formulated according to the actual situation of customers.

Disc granulation process is simple and relatively cheap. In the organic fertilizer production line, most customers will choose disc granulator. How to improve the pelletizing rate of disc granulator has always been a concern of customers, so how to improve the pelletizing rate of disc granulator? What matters should disc granulator pay attention to when processing organic fertilizer?

Control the moisture content of granulating particles
In the production process of fertilizer granulator, how to preliminarily test the particle water quantity? A simple and practical method, hand feeling method: grasp a ball of materials from the disc granulator, and the hand can form a ball. It is appropriate to release it with a touch of a finger. The grain thus made has high yield and is not easy to block the screen surface.

Strictly control the quality of powder fertilizer
According to the formula of organic fertilizer, carefully control the quality of various raw materials.
Iron block, stone larger than 10 mm and wood block larger than 10 mm are strictly prohibited for raw material discharging and feeding. Rice bran and sand can’t have many quality indexes either, which seriously results in low yield.

Key technology of operating disc granulator
Do well in operator’s technical training of disc granulator, improve workers’ technical quality and operation skills.

Select the nozzle of disc granulator and adjust the nozzle
Generally, B-type spherical screw or B1 type rudimentary spiral nozzle is the best choice for disc feeder.
According to hydrodynamics, it has been proved that the larger the pressure is, the smaller the through hole is, and the larger the droplet diffusion surface is. Under the same pressure, the spray hole of the nozzle is small and the droplet density is small; the spray hole is large and the droplet density is large.

A new type of blade in the disc of the reformed disc granulator
Good blade, even and beautiful grain size, blade material must be 16m, blade is divided into front blade and rear blade, there is no gap between the two blades.

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.
