How to Solve Dust Pollution in Organic Fertilizer and NPK Fertilizer Production

Written by fertilizer production line on December 4th, 2019.

Because of the characteristics of materials, a lot of dust will be produced in fertilizer production, which will pollute the environment. In order to avoid this problem, dust removal devices should be set up in the design of organic fertilizer manufacturing process and NPK fertilizer production project to solve the problem of dust emission.

Dust Problem in Organic Fertilizer Production Line

In the organic fertilizer production line, when the moisture content of raw materials is low, they are often crushed and uneven solids. When the raw materials are transported to the equipment, if they are transported in the open air, there is no effective sealing measures, so the dust concentration in the air of the organic fertilizer manufacturing site will be too high. In addition, most small and medium-sized enterprises lack effective treatment means when discharging exhaust gas, which leads to the emission of exhaust gas not up to the standard and dust pollution.

Dust Problem in NPK Fertilizer Production Process

Take NPK fertilizer production project as an example, because the raw material of NPK fertilizer is brittle, it is easy to form small particle dust. When the dust is disturbed by airflow, it is easy to fly. Because of the low water content of NPK fertilizer, the dust is easy to absorb and adhere to the equipment. Therefore, when grading by using the screening device, the dust can easily block the sieve holes of the screen, thereby affecting the grading effect and even damaging the screen. As a result, the screen must be frequently replaced, on the one hand, the production cost is increased, on the one hand, to improve production costs, on the other hand to reduce production efficiency.

NPK Fertilizer Production Process

To solve the problem of dust pollution in the fertilizer manufacturing process, it is necessary to set up a dust collector room and dust collector equipment in the process of fertilizer production. Tianci Fertilizer Machine Manufacturer have designed a special cyclone dust collector to remove dust from the organic fertilizer manufacturing process. And in the construction of fertilizer plant, dust collector room is more suitable for large NPK fertilizer production line, we can help customers build dust collector room.

How to Preventing Caking from the NPK Fertilizer Production Process

NPK compound fertilizer is prone to cake because of its strength, moisture content, storage and so on. This article will introduce how to prevent caking from the process operation of NPK fertilizer production process.

NPK fertilizer production equipment produce products with smooth and uniform particles

Non-uniform particles, too many fine particles, non-smooth fertilizer, the compressive resistance, wear resistance is also poor, easy to be compressed and deformed in storage and transportation. The contact area between particles increase, which is easy to agglomerate. In order to produce products with uniform and smooth particle size, appropriate fertilizer granulator machine should be selected. Disc granulator and rotary drum granulator can produce moderate size particles and meet the requirements. If there is a higher requirement for the shape of the particles, it can also be combined with the ball shaping machine to polish the particles to ensure that the shape is qualified.

Strengthening the control of screening machine

In order to ensure the consistency of particle size and reduce the caking of powder, it is necessary to screen particles with the rotary drum screener machine. According to the particle size of the product, different screens can be selected, and secondary screening can be selected in the process. Pay attention to the material screening in production, timely clean the screen.

Dryer reduces product water content

NPK compound fertilizer has a high water content, which will lead to salt reaction and cause hardening. The higher the water content, the easier the particles to agglomerate. Therefore, the NPK compound fertilizer production line must use a dryer to reduce the moisture content to the allowable range.

After the particle is dried by the dryer, the temperature is higher and the hygroscopicity effect will appear, so it needs to be cooled. The cooler reduces the material temperature to room temperature, and the product can be saved.

Coating treatment is used in NPK fertilizer production process

Choose the suitable material and use the fertilizer coating machine to coat the particles. At the same time, pay attention to the amount of wrapping agent added. The amount of wrapping agent added is small, the particles are not wrapped completely, the effect is poor; the amount of adding is large, the wrapping oil will infiltrate into the inside of the NPK fertilizer, and the product is easy to cake.

How to maintain fertilizer manufacturing equipment

Fertilizer equipment is an important tools for fertilizer manufacturing process. Fertilizers processed by fertilizer equipment have abundant and diverse nutrients, which are rich in materials needed by vegetation and can meet the needs of various nutrients for crop growth. After fertilizer equipment is put into production, attention should also be paid to maintenance and maintenance, not just production. Running the equipment according to usage standard to produce fertilizer, check regularly to ensure normal operation, so that the service life of the equipment is longer. Following are some techniques for maintaining fertilizer equipment.

Bearings in fertilizer production equipment bear all the loads of the machine, so good lubrication has a great relationship with bearing life. The use of bearings affects the service life and operation rate of the machine. Therefore, it is recommended that bearings be inspected once every 7 days and lubricating oil be injected into them regularly.

Check the machine of the whole fertilizer production line regularly, and pay attention to whether the work of each part of the fertilizer granulator machineis normal. The wear level of vulnerable parts should be checked, such as cleaning the chain every 3 days, and replacing the worn parts in time.

If there is a fault in the running of the rotating gear, stop immediately to check and eliminate it.

The chassis of fertilizer production equipment should be placed smoothly to remove dust and other impurities, so as to avoid special circumstances and serious accidents in the production of machinery.

fertilizer manufacturing process

It is suggested that fertilizer factories should do the following for fertilizer manufacturing process:

1) Improve the maintenance system and eliminate hidden dangers. When the fertilizer production line is put into production, it is necessary to formulate rules for the use of various machines and maintenance systems. Operators can operate and maintain according to the regulations, so as to prevent safety accidents and avoid unnecessary failures of machines. For example, when workers clean and maintain the machine, they can find out the problems existing in the machine and check them in time to avoid greater losses.

2) Maintenance of the machine should be carefully and in place. Whether the NPK fertilizer production process can operate efficiently and normally and give full play to its performance is not only related to the quality of the equipment itself, but also to the correct use and proper maintenance of the operators. Maintenance of the machine is troublesome, but if not done, it will affect the production of equipment products, maintenance costs and replacement costs of vulnerable parts will continue to increase.

3) It is necessary to assign responsibility, check and record every day, lubricate and maintain the important parts of the equipment (vulnerable parts, motors, reducers, bearings, etc.) according to the instructions before leaving work every day. If there is any damage, it should be replaced or repaired in time to avoid affecting the normal production the next day.

4) The cause of equipment failure should be analyzed in time and lessons learned. The reason for the failure of fertilizer equipment may be the failure of the machine itself, or the improper operation and maintenance, etc. Once the fertilizer equipment fails, we should analyze the causes of the problems, take measures to learn lessons and prevent similar situations from happening again.
