How to improve the pelletizing rate of NPK fertilizer production

NPK compound fertilizer is characterized by simple composition, high nutrient content, low dosage, quick fertilizer effect, convenient application, transportation and storage, and rapid improvement of yield and quality. In order to produce large quantities of high-quality compound fertilizer, the first step is to produce good fertilizer granules.

 

The main factors influencing NPK fertilizer production line are as follows:

  • Production equipment;
  • Process technology;
  • Physical and chemical properties of raw materials;
  • Production formula and added conditioner;
  • Air temperature and air volume at the outlet of the dryer;
  • Temperature and liquid phase quantity of granulating materials;
  • Material flow;
  • Material return ratio;
  • Quality of operators;
  • Climatic conditions.

 

Only by integrating the above factors into making fertilizer granules, can we produce NPK fertilizer with high yield and good quality, one of which is indispensable.

NPK fertilizer production line

  1. Improving the performance of NPK fertilizer production equipment is the basis

Choose qualified production equipment, choose well-equipped, complete test means, reliable product quality manufacturers, under the guidance of experienced personnel to buy, late equipment management and maintenance personnel to have a certain professional level. Zhengzhou Huaqiang Co.Ltd are leading agricultural fertilizer machine manufacturers in China. We has strong technical strength in fertilizer machines. All of our products comply with international quality standards and greatly appreciated in a variety of different markets throught the world.

 

  1. Choosing ammonium phosphate with good viscosity as raw material is the premise

The pelletization of NPK fertilizer mainly depends on the viscosity of ammonium phosphate and conditioner, and the poor viscosity of ammonium phosphate directly affects the pelletization rate of compound fertilizer. Therefore, when purchasing ammonium phosphate, we should consider not only nutrient content and price, but also its viscosity. From the actual production experience, the viscosity of diammonium phosphate is better than that of monoammonium phosphate.

 

  1. Ensuring the fineness of raw materials and feedbacks is essential

The finer the powder of the raw material, the better the viscosity of the material, the more important it is to improve the efficiency of the crusher

Chain crusher to help make the big granules into the fine powder and get back to fertilizer granulator machine. It is simple and compact in structure, cover small area, easy maintenance such characters, crushing effect is good, smooth operation, easy to clean.

 

  1. Material mixing is an important measure to improve the NPK fertilizer production line efficiency

The material is mixed evenly, on the one hand, the mixer mixes the fresh material evenly, on the other hand, the mixer combines the returned material and the fresh material evenly. Because the fine powder in the returned material is mostly potassium and nitrogen with poor viscosity, it is the material that is least likely to form into a ball, while the fresh material has better viscosity and is easy to form into a large ball in production. Mix the two thoroughly to prevent the formation of large balls and too much powder.

 

  1. Suitable moisture and pelletizing temperature are the key

Only when the temperature and water content of granulating materials are adjusted to the optimal point can the granulation area be ensured to be normal.

The disc fertilizer granulator is suitable for the production with small yield, and the rotary drum granulator is suitable for the mass production of NPK fertilizer. Addition of moisture during granulation requires certain experience of operators.

 

  1. Suitable air volume and stable furnace temperature are the preconditions

The size of the air volume directly affects the drying effect, the air volume in the dryer, the drying effect is good. If the air volume is too large, it is easy to extract the powder in the simplified body, and the wind speed should be less than 2m/s.Best cooling head end temperature difference is about 100℃, the import and export temperature cannot frequent adjustment. When urea is used as nitrogen source, the temperature should be determined according to the amount of urea. The more urea is used, the lower the drying operation temperature will be.

Fertilizer equipment

How to Make Organic Fertilizer by Feces Composting

Fecal composting organic fertilizer manufacturing process is to adjust the carbon-nitrogen ratio in the manure of the livestock and poultry by turning machine, manually controlling the conditions of water, temperature, pH and the like, and treating the manure of the livestock and poultry by the fermentation of the microorganisms to produce organic fertilizer.

 

I. Major organic fertilizer production equipmentfor composting

The composting process requires a large number of organic fertilizer processing equipment.

(1). Pre-treatment equipment: mainly include stockyard, unloading platform, feeding door, loading machinery, transport machinery and so on.

(2). Composting equipment: mainly trough compost turning machine, windrow turner machine, fermentation tank.

(3). Fertilizer granulator machine : mainly drum granulator, disc granulator, flat-die extrusion pelleting machine, organic fertilizer granulator, ring-die pelleting machine.

(4). Screening and packaging equipment: mainly drum screener, fertilizer packing machine.

II. Main Technical Parameters of composting

(1). C/N ratio: C/N balance of compost mixture is the key factor for microorganisms to achieve better biological activity. The C/N ratio of compost mixture should be kept at 25-35:1.

 

(2). Humidity: Aerobic composting should generally be maintained at 40-70%.

 

(3). Acidity and alkalinity: Acidity and alkalinity vary with the types of compost mixtures and different stages of composting process. Normally, they need not be regulated. If they need to be regulated, they can be regulated by adding alkaline or acidic substances to the mixture before the beginning of composting degradation.

 

(4). Other design parameters: Rectangular fermentation stacking composting mode, the windrow turner should be used regularly to turn the pile, so that the temperature is kept below 75℃, and the turning frequency is 2-10 days/time. The width and depth of rectangular stacks are limited only by the overturning equipment. The stacks are generally 1.2-1.8 meters deep and 1.8-3 meters wide. The height of the compost is usually 2.5-4.5 meters, and the width is usually twice the depth. Fermentation tank composting, need to build fermentation tank, fermentation tank length is unlimited.

 

III. Matters needing attention in composting

(1). Composting time: Composting time varies with C/N ratio, humidity, weather conditions, type of composting operation and management, waste and additives. The composting time of well-managed strip-cutting fermentation compost in summer is generally 14-30 days.

(2). Temperature: We should pay attention to the monitoring of composting temperature. The composting temperature should exceed 55℃, so as to be conducive to microbial fermentation and kill pathogens.

(3). Humidity: Pay attention to monitoring the humidity of compost mixture periodically. Excessive or low humidity will reduce or stop the composting speed.

(4). Odor: Odor is a good indicator of composting operation stage. Decay odor may mean that compost is changed from aerobic to anaerobic.

Classification of organic fertilizer machine

Different type organic fertilizer machine and inorganic fertilizer machine are designed and produced by the fertilizer machine manufacturers.The organic fertilizer can be classified as different type,we can share the common type with you about the fertilizer manufacturing process.The fertilizer machine manufacturers designed different type fertilizer production lines and different type fertilizer machines to produce the organic fertilizer granulator or inorganic fertilizer granulator.Using the complete fertilizer production line not only improve the efficient,it also simplify the process of producing the organic fertilizer granulator.In the organic fertilizer production line it is equipped with different type organic fertilizer machine.

Organic fertilizer is divided into :
1.Straw organic fertilizer:Straw is the by-product crop harvest.It is one of the precious organic fertilizer resources of its rich variety and quantity.Crop straw is the crop residue left after seed harvest,including cereals,beans,potatoes,oil hemp,cotton,sugarcance,tobacco and other crop straw.At present,the annual output of crop straw in the world is more than 2 billion tons,which is the fourth largest engery in the world after coal,oil and natural gas.The basic components of straw are cellulose,hemicellulose and lignin.Due to the structural differences of each part,the microorganisms involved in the decomposition of straw are different in each stage.The water,aeration,temperature,C/N ratio and PH value of straw must be well controlled in the treatment stage.
2.Manure organic fetilizer:Excrement is the excrement of human and livestock.It is a traditional way to treat excrement when it is returned to the field as fertilizer.It hass achieved good results in improving soil and increasing agricultural output.The folk saying”rasing pigs without making money,looking back at the fields’ exactly reflects the position of excrement in agricultural production.The use of animal manure as fertilizer is the most fundamental way out for these low use value substances,and it also the most commonly used way to deal with animal manure in the world.At present,due to the use of a large number of antibiotics,stimulants,tranquailizers,livestock manure must be treated with high temperature and high pressuse to make organic fertilizer.There,when using the animal manure as the organic fertilizer raw materials we need to notice that we are first to ferment the animal manure using the fermentation compost turner machine.After put them into the fertilizer granulator machine to make into organic fertilizer granulator.
