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

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.

Benefits of Organic Fertilizer Granulator Impact of Agriculture on the Environment

Due to the development of China’s manufacturing industry and the constant changes in the level of natural and economic development, people’s traditional organic fertilizer equipment cannot be fully integrated into the standard under the new situation, so we have a stronger method for it. In the face of various practical problems, we carried out relevant scientific research. Later, people found that relatively new methods promoted the development of organic fertilizers on the basis of traditional experience, and greatly improved our environment. Has made great contributions!

Generally, the disc granulator for organic fertilizer is divided into two parts, in which the fermentation part is divided into three types of equipment: premixing equipment, dumper and refining equipment; The organic fertilizer granulator equipment is divided into two mixers – pulverizer – granulator – dryer – cooler – screening machine coater – automatic packer, and the equipment is connected by conveyor or elevator. Auxiliary equipment, baffle dedusting, cyclone dedusting, ink dedusting, induced draft fan and other equipment. In the past, we needed to adapt to the development of nature, which had little impact on our environment. However, with the continuous development of society, this item has also changed. To a certain extent, we have the ability to change nature, but we still passively adapt to long-term changes in climate and geology. What we can remedy is limited.

For a long time, agriculture has been an important industry that affects people’s ecological environment. Excessive deforestation and predatory farming, as well as the use of chemical fertilizers, pesticides, herbicides and fungicides, have led to environmental pollution and destruction of the ecological resource system. All these have caused great harm to our natural environment – global warming.

Maintenance requirements of granulator equipment in organic fertilizer production line

The organic fertilizer production line mainly consists of five parts: raw material warehouse, belt conveyor, crushing, screening and packaging,; It is suitable for small and medium-sized organic fertilizer production process with compact layout, scientific and reasonable layout, advanced technology, energy saving and consumption reduction, no three emissions, stable operation, reliable operation and convenient maintenance, wide adaptability of raw materials, and suitable for various proportions of organic compound fertilizer, biological organic fertilizer, urban sludge, domestic waste organic fertilizer, etc. The designed annual production capacity is 1-100000 tons.

Maintenance requirements for organic fertilizer granulator

  1. Dust and other objects on the chassis plane of movable equipment shall be removed to avoid the machine. When encountering non fragile materials, the movable bearing cannot move on the underframe, causing serious accidents.
  2. If the bearing oil temperature rises, stop the machine immediately to check and eliminate the cause.
  3. In case of any impact sound of rotating gear during operation, stop the inspection immediately and eliminate it.
  4. The bearing of the bearing crusher bears all the loads of the machine, so good lubrication is closely related to the bearing life. It directly affects the service life and operation rate of the machine, so the injected lubricating oil must be clean and well sealed. The main oil filling parts of the machine include rotary bearings, roller bearings, all gears, movable bearings and sliding surfaces.
  5. Newly installed tires are easy to loosen and must be checked frequently.
  6. Pay attention to whether all parts of the machine work normally.
  7. Pay attention to check the wear degree of easily worn parts, and replace worn parts at any time.

Why npk fertilizer production line finally uses packaging machine

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.

Which raw materials are applicable to the double roller press granulator

The double roller press granulator is a molding machine that can make materials into specific shapes. The double roll extruding granulator has a particularly good granulating effect on ammonium bicarbonate, ammonium chloride, monoammonium phosphate, etc. The granulation rate can reach 85%, without drying, with less investment and quick effect.

  1. Thedouble roller press granulatorhas no drying process, granulating at room temperature, one-time forming, low investment and good economic benefits.
  2. Small power, reliable operation, no discharge of three wastes, stable operation, convenient maintenance, reasonable process layout, advanced technology and low production cost.
  3. The invention has wide adaptability to raw materials and can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, coal, metallurgy, etc. It can also produce various concentrations and types of compound fertilizer (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.).
  4. Double roll extruding granulator, especially rare earth, ammonium bicarbonate and ammonium sulfate compound fertilizer.

Working principle of the double roller press granulator: the belt and pulley are driven by the motor, transmitted to the driving shaft through the reducer, and work in reverse synchronization with the driven shaft through the split gear. The material is added from the feed hopper, demoulded and granulated by double roll extrusion, and then transported to the crushing chamber through a pair of chains for crushing. The finished granules (balls) are separated under the screen, and the returned materials are mixed with new raw materials for granulation. With the continuous rotation of the motor and the continuous entry of materials, mass production is realized.

Organic fertilizer grinder can improve environmental pollution

What benefits does the organic fertilizer Crusher bring to the environmental pollution? As China’s agricultural production relies excessively on fertilizer and other fertilizer sources, the soil structure has changed. The existence of these problems, to a certain extent, threatens the area of a small number of cultivated land in China. The country has always attached great importance to them. Through research and practical tests, it is found that the organic fertilizer produced by the organic fertilizer production line can alleviate the problems of soil compaction and salinization due to its rich nutrients and organic matter content, which is a necessary fertilizer source for the country to carry out sustainable agriculture and build ecological agriculture. Therefore, the organic fertilizer production line has been strongly supported by the state.

The organic fertilizer Crusher is specially designed for crushing organic fertilizer and compound fertilizer. After the materials enter the crusher through the feed port, they are crushed into materials that can pass through the radial clearance and discharged through the discharge port. The inner wall is made of rubber or stainless steel (depending on the customer’s needs), which makes the surface smooth and easy to clean. It changes the phenomenon that the inner wall of ordinary grinder is rough, easy to accumulate powder, and difficult to clean, so that the production of food, medicine, chemical industry, etc. is more in line with national standards and GMP sanitary requirements. During the crushing process of the organic fertilizer chain crusher, high-strength cemented carbide chain plates with synchronous speed are used. The inlet and outlet design is reasonable, the broken materials are uniform, not easy to stick to the wall, and the cleaning is convenient. The crusher adopts the latest technology, selects high-quality steel, and carries out system optimization design, with large output and high reliability. The organic fertilizer chain grinder has the characteristics of reasonable structure, fast feeding, stable performance and strong impact resistance.

China has a vast territory, and its natural conditions, agricultural production methods and economic development levels vary greatly from region to region. These conditions have a great impact on the utilization of manure resources. It is of positive significance to promote the comprehensive utilization of livestock and poultry manure resources by summarizing the experience and problems of existing farms in using manure resources and exploring a manure resource utilization model suitable for the characteristics of various regions.

Process characteristics of roll extruding granulator for organic fertilizer

  1. Low energy consumption oforganic fertilizer roller granulator: extrusion granulation is the granulation of materials at room temperature. Compared with other granulation methods, it does not require drying measures such as fuel oil and gas. The production only requires power consumption and a small amount of cooling water (for roller shaft cooling), and the power consumption per ton of product is only about 30 kW/h.
  2. There is no need to add adhesive to the organic fertilizer roller granulator: other granulation processes are basically wet processes, which must have a drying process, with high energy consumption and high product moisture. However, dry granulation does not require additional additives, but only uses the intermolecular force of the material itself, simplifying the process and reducing energy consumption.
  3. The investment of theorganic fertilizer roller granulatoris low: because the drying process is omitted, and the return ratio is low (accounting for about 35% of the total feed of the extruder), the process flow is simple and the investment is low.
  4. Wide range of applicable raw material particle specifications: extrusion granulation has no special requirements on the particle size of raw materials. Both 1~4mm granular materials and fine powder materials can be used. Unqualified powder materials and powder products can be better used, and the cost can be reduced by using powder materials.
  5. Wide capacity range oforganic fertilizer roller type extrusion granulator: for the extrusion granulator, the effect of economic scale is not obvious, and the unit capacity of 1~50 t/(h. set) can be economically designed, so the applicable capacity range is wide.

The only disadvantage of producing granular fertilizer by roller extrusion granulation is that the product shape is irregular particles, but the irregular particle shape has no effect on the application of fertilizer, and the dressing process can be added to further round the particles. The fertilizer produced by extrusion granulation has sufficient strength, less dust, no agglomeration, narrow particle size distribution range, and good fluidity, so it has good economic benefits.

Routine maintenance Stable operation of organic fertilizer crusher

It is natural to use special fertilizer production equipment to produce fertilizer, but due to the particularity of fertilizer equipment, the working environment of fertilizer equipment is relatively poor, and sometimes the equipment frequently used is severely corroded less than a year ago. Normal loss is inevitable, but necessary equipment cleaning and maintenance can prolong the service life of the organic fertilizer crusher.

When crushing raw materials, the raw materials should not have large solid substances, and the organic fertilizer raw materials have stones or even iron blocks, which will seriously damage the high-speed rotating crusher rotor. Only by ensuring that the raw materials are clean and free of impurities, the fertilizer processing equipment in each process will not be affected.

During daily use, the organic fertilizer crusher shall be maintained in a timely manner, and a special person shall be designated to take charge. The organic fertilizer grinder must be thoroughly inspected regularly to prevent problems. Only in this way can problems be found and solved in time. It must be known that the shorter the maintenance cycle of the machine is, the smaller the possibility of error is, and the more reliable the operation of the equipment itself is.

From the perspective of the long-term benefits of the organic fertilizer crusher, although the performance of the organic fertilizer crusher is stable and the mechanical parts are solid, the machinery itself is easy to wear due to the increase of working intensity in daily work. Therefore, in the regular maintenance phase, especially in the work, we should also do a good job in equipment maintenance and try to operate according to the operating instructions of the organic fertilizer granulator. Learn the maintenance method of organic fertilizer crusher, and take reliability and safety as the leading maintenance method to ensure the safety maintenance of maintenance personnel.

For a long time, the safety of organic fertilizer crusher prevention depends on its reliability. Therefore, it is believed that the more prevention work is done, the shorter the maintenance cycle is, the more reliable the mechanical equipment is.

The mechanical equipment relies on the motor and reducer to ensure the power source, and is regularly filled with lubricating oil to better ensure their operation. There are many types of lubricants, so it is necessary to select the appropriate oil according to the different climate and mechanical driving principles. According to the wet and hot environment in the north and south, cycloidal pin gear reducer and ZDZQ series reducer and other needs, selecting the appropriate lubricant can better ensure the operation of the equipment. In addition, adjust the amount of charging oil when filling the fuel to avoid too little effect or waste.

Different equipment has different capacities, so the equipment shall be used reasonably according to the processing capacity. For example, when supplying feed to the warehouse, let the forklift slowly drop the material to avoid breaking the equipment. Raw materials cannot be fully filled during mixing. Materials shall be added after starting the mixer to prevent excessive mixing resistance and equipment damage.

In fact, looking at these operating regulations, many of them are related to details. In a word, the organic fertilizer production equipment must be well managed in order to operate better and bring us more benefits.

The reason of raw material precipitation during npk fertilizer granulation

When some compound fertilizer equipment production lines are processed by rotary drum granulator, they can dissolve the fertilizer into a certain proportion, but if the energy exceeds a certain amount, it will produce salt analysis and precipitate another substance.

Amino acids and zinc sulfate dissolve well in water, but when they are together, Zinc Sulfate Precipitates amino acids. The pH value of solution, part of the supply, metal salt dissolved in acid will produce precipitation and dissolve in alkaline medium, while some substances such as humic acid will form precipitation and dissolve in acid solution. Amino acids and humic acids can be analyzed by salt analysis, zinc, copper, iron, manganese and salt analysis. Therefore, it is more important to choose suitable raw materials for fertilizer production.
Fertilizer granulator granulation should consider whether the substances are compatible. Some substances cannot be mixed in the precipitation reaction, and precipitation occurs when they are mixed into water, such as zinc, copper, iron and manganese plasma. In the case of phosphate, borax will precipitate, the precipitate is insoluble in water, and the phosphate precipitates molybdate ammonia water, and these commodities cannot be produced at the same time. They not only produce precipitation, but also lose their fertilizer efficiency.
Raw materials are insoluble in water, so the proportion of fertilizer is blindly increased. At room temperature, the solubility of borax and boric acid in water is 30 kg / T, and most of them will precipitate. If several kinds of fertilizers are soluble in water, there is also a great demand. For example, zinc sulfate is soluble in water, potassium sulfate is soluble in water, and two kinds of raw materials are soluble in water, which can produce potassium sulfate crystals.
