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.


  1. 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.


  1. 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.


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


  1. 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.


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.

How to Prevent Caking in NPK Fertilizer Production Process

The problem of fertilizer caking usually occurs in the process of fertilizer processing, storage, transportation, which is caused by the moisture absorption, dissolution and evaporation of fertilizer grain, and recrystallization. In this process, a crystal bridge is formed, resulting in the formation of small particles into large particles and caking.

So how to avoid the fertilizer caking in NPK fertilizer production line?

NPK fertilizer production line

  1. Choose suitable raw materials.

Most of the materials used in fertilizer production, such as ammonium salt, phosphate, trace element salt, potassium salt and so on, contain crystalline water and are easy to absorb moisture, such as ammonium sulfate, phosphate and trace elements are easy to agglomerate and become insoluble in water. Urea is easy to precipitate water and agglomerate when it meets trace element salts.

Choose raw materials that are not easy to cake and produce fertilizers that are not caking. For example, fertilizers with humic acid as the main raw material and fertilizers with amino acid as the main raw material are not easy to cake. In addition, when choosing materials, try to be as dry as possible.


  1. In NPK fertilizer production process, the moisture content of fertilizer and packaging temperature should be reduced, and the appropriate production time should be selected.

Fertilizer production is generally non-closed production. In the NPK fertilizer production line, the greater the air humidity, the easier the fertilizer to absorb moisture and agglomerate. Fertilizer production avoids the rainy season and concentrates on producing fertilizer on dry days. In the process of fertilizer production, the raw materials are heated by the drum dryer, so that the moisture content of the fertilizer is controlled below 0.6%, the cooling time of the fertilizer is prolonged, and the packaging temperature is lowered, so the fertilizer is not easy to cake.


  1. Adding anti-caking agent to reduce the physicochemical reaction between NPK fertilizer particles.

The higher the room temperature, the easier it is to dissolve. Generally, raw materials dissolve in their own crystalline water and cause caking. Addition of talc powder, humic acid and other non-caking powder can also add some surfactants to prevent caking.


  1. Reduce the stacking height and storage pressure of fertilizer.

The greater the external pressure of fertilizer, the easier the contact between crystal and crystal, the easier the caking; the smaller the external pressure, the more difficult the caking.


  1. Precise screening of NPK fertilizer by screening machine can further improve the fertilizer uniformity.

NPK fertilizer particles are not uniform in size, with small gap between particles and more contact area, it is easy to agglomerate. If the compressive strength of fertilizer granules is low, the fertilizer is easy to deform and break during packaging, transportation and storage, which will increase the contact area between granules and also lead to fertilizer caking.

If a fertilizer factory produces a large amount of fertilizer with NPK fertilizer production line, it can be screened twice with a screener machine to obtain suitable fertilizer granules.


  1. Fertilizer granulator machine for material treatment.

Because of the small contact area between the round particles, it is not easy to crystallize and agglomerate. Therefore, NPK fertilizer granulation production process is conducive to fertilizer storage, transportation and fertilization.

When granules are produced by disc fertilizer granulator (or rotary drum granulator), they must be dried and cooled.

When NPK compound fertilizer granules are produced by double roller press granulator, the dryer is not used, but the adhesion of raw materials for fertilizer production must be good.
