Common problems of NPK compound fertilizer production

NPK compound fertilizer is synthesized from chemical raw materials needed by various plants. NPK fertilizer has played a significant role in increasing production and income of agricultural production. So what are the common problems in the NPK fertilizer production process and what needs to be known about the equipment for the production of NPK fertilizer?

 

  1. Specialized NPK fertilizer production equipment is naturally used for fertilizer production, but due to the nature of compound fertilizer itself, fertilizer equipment is easy to be corroded, and some frequently used equipment has been seriously corroded in less than a year. Normal loss is inevitable, but necessary equipment maintenance can prolong the service life of fertilizer processing equipment.

 

  1. When crushing raw materials, we should try our best to ensure that there are no large hard blocks in the raw materials. In the compound fertilizer raw materials, if there are stones or even iron blocks, it will cause serious damage to the high-speed rotating mill rotor. Only by ensuring that the raw materials are clean and free of impurities can the equipment of fertilizer production process not be affected.

 

  1. Mechanical equipment relies on motor and reducer to obtain power source. Periodically adding lubricating oil to fertilizer granulator machinecan better ensure their operation. There are many types of lubricating oil, so we should choose suitable grease according to the principle of climate and mechanical transmission. For example, in cold areas and hot and humid environment, it is necessary to select the appropriate lubricant to ensure better operation of the equipment. In addition, when filling oil, control the amount of oil, so as not to affect the effect too little, or too much waste.

 

  1. Different equipments have different productivity. We should use the equipments reasonably according to their productivity. For example, in the compounding stage of fertilizer manufacturing process, forklift trucks should be allowed to drop materials slowly when feeding into silos, so as not to damage the equipment. When mixing, the raw materials should not be too full, and materials should be added after the start of the mixer, in order to avoid equipment damage due to excessive stirring resistance.

In short, there are many details about the production of NPK fertilizer. Only by maintaining the fertilizer production equipment can they work better and bring us more benefits.

 

Bio-organic fertilizer production process and equipment

Bio-organic fertilizer refers to a kind of fertilizer that combines livestock manure as the main raw material, inoculates microbial complex microbial agents, completely kills the bacteria and eggs by fermentation, and turns macromolecules into small molecules. The biofertilizer project is to feed the fermented material into the organic fertilizer production line equipment and process it into commercial organic fertilizer.

Organic fertilizer production line and processing raw materials
Main ingredients: The raw materials for the production of bio-organic fertilizer are mainly agricultural waste such as livestock manure and crop straw.
Other ingredients: different sources of raw materials, fermentation methods, equipment, etc., the ingredients of organic fertilizer production are different. The specific formulation depends on the source of the organic material.

Fermentation and decomposing of bio-organic fertilizer process
The fermented materials can be stacked on the ground or fermented in the fermentation tank. Fermentation tanks are usually better in flattened or semi-closed fermentation chambers than on flat ground. The material needs to be turned over regularly by using a turning machine, and it is turned over every 3 days. After 25-30 days of fermentation, the temperature gradually decreases from 70-80 degrees Celsius to stable, and the ripening is completed.

Main equipment and process for biofertilizer project:
1. Crushing and stirring pretreatment
Crushing equipment: semi-wet material crusher
This machine is mainly used for the crushing of bio-fermented organic fertilizer materials with water content of 25%~50%. The pulverization particle size of the semi-wet material pulverizer meets the granulation requirements, and the machine can be adjusted within a certain range according to the needs of the user.

2. Mixing equipment: horizontal mixer
This machine is mainly used for batch mixing of raw materials, and the materials can be fully mixed. The horizontal mixer has high mixing strength and low residual amount, and is suitable for mixing feed, concentrated feed and premix additives.

3. Granulation equipment
The composted material is subjected to a granulation process so that it has a certain strength and shape to be applied as an organic fertilizer. Granulation is a key step in the production of bio-organic fertilizers. Bio-organic fertilizer has a variety of fertilizer granulator machine. According to the structure of the granulator, the pellet method can be divided into a disc granulator and a drum granulator. According to the position of the press rolls, the extrusion method can be divided into a roller press granulator, flat die granulator and ring die granulator.
