Building an npk production line requires a compound fertilizer granulator. There are many compound fertilizer processing and granulation equipment. Some companies do not know how to choose a suitable compound fertilizer granulator. What is the compound fertilizer granulation equipment introduced today? There are three main types of compound fertilizer granulator: drum granulator, disc granulator and double-roller granulator. What is the difference between these compound fertilizer granulators? What are the advantages and disadvantages of each method?

The disc granulator mainly uses the rolling of the disc surface and the granulation of the granules themselves, and is used together with the upper mixer to achieve a high spheroidization rate. The investment cost of granulator equipment is low, and the production capacity is strong, but the dust of open-air granulation is relatively large.

The barrel of the drum granulator equipment is lined with a special rubber plate or an acid-resistant stainless steel lining to realize automatic scar removal and tumor removal, eliminating the traditional scraper device. A drum granulator is a forming machine that shapes materials into specific shapes.

The main working method is granule wet granulation. With a certain amount of water or steam, the basic fertilizer can fully react after being humidified in the tank. Under certain liquid phase conditions, with the help of the rotating motion of the cylinder, the extrusion force between the material particles condenses into balls. The investment cost of chemical fertilizer equipment is high, the production capacity is strong, and the dust of drum granulation is relatively small.

The double-roll granulator adopts non-drying normal temperature process to produce, one-time molding. The equipment has low investment, quick effect and good economic benefit. The whole set of equipment is compact in layout, scientific and reasonable, and advanced in technology. Energy saving and consumption reduction, no waste discharge, stable operation, reliable operation and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of raw materials such as compound fertilizer, medicine, chemical industry, feed, etc., and the product granulation rate is high. Various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers, etc.) can be produced.

Ammonium, phosphorus and potassium fertilizers

Ammonium phosphate potassium fertilizer is a ternary compound fertilizer made of ammonium sulfate, potassium sulfate and phosphate in different proportions, or by adding potassium salt into ammonium phosphate. The nutritional ratios were 12-24-12, 10-20-15 and 10-30-10, respectively.

The proportion of phosphorus in ammonium phosphate and potassium fertilizer is relatively large, so nitrogen and potassium fertilizer can be applied properly, and the ratio can be adjusted to give full play to fertilizer efficiency. Potassium ammonium phosphate fertilizer is a kind of high concentration compound fertilizer. How to make npk compound granules? Go here for more.

NPK compound fertilizer contains two or more kinds of macroelements, which can provide rich nutrition for the growth and development of soil and plants. What should be paid attention to when applying NPK compound fertilizer?

There are different concentrations of compound fertilizer, we should pay attention to choose the appropriate concentration. At present, most compound fertilizers are distributed according to the average nutrient status of soil types and the proportion of fertilizer required by crops in a certain area. There are high, medium and low concentration compound fertilizers on the market.

Generally, the low concentration of total nutrients is between 25% ~ 30%, the medium concentration is between 30% ~ 40%, and the high concentration is more than 40%. And crops. Generally speaking, high concentration compound fertilizer is used for economic crops with good quality, less residue and high utilization rate. The concentration of compound fertilizer is high. Avoid direct contact between seeds and fertilizer. The nutrient content of compound fertilizer is high. If the seeds or seedling roots are directly contacted, the emergence of seedlings will be affected, and even the roots will be burnt. When sowing, seeds should be mixed with acupoints, and compound fertilizer should be applied in strips with an interval of 5-10 cm.

Matters needing attention in application of NPK compound fertilizer

It is necessary to pay attention to the nutrient composition of compound fertilizer with different proportion of raw materials. Different brands and concentrations of compound fertilizer use different raw materials, which should be selected and used according to the types of soil and crops. The compound fertilizer containing nitrate is not suitable for leaf vegetables and paddy fields. It is not suitable to use compound fertilizer containing ammonium ion, potassium chloride or chloride ion in saline alkali soil, potassium sulfate in crops or saline alkali soil, and potassium sulfate in paddy field and acid soil, otherwise it will reduce fertility and even poison crops.

The compound fertilizer containing two or more kinds of large elements is easy to volatilize or lose with the rain, and the phosphorus and potassium are fixed by the soil, especially the mobility of phosphorus in the soil is small, and it is not easy to be absorbed. The crop root system is on the surface, which is not conducive to deep root system. The drought condition in the fertilizer can not be dissolved, and it is worse in the development, so the compound fertilizer should go deep into the soil.

1. The technical characteristics of compound fertilizer granulator, the granulation rate is more than 90%, and the specification is incomplete, it can also enter the pulping machine again for secondary processing, and the cylinder power is small. The shell is made of wear-resistant steel, which effectively extends the service life of the equipment.

2. The reducer of the granulator drives the belt through the motor. There is a pinion on the shaft of the reducer, which coincides with the teeth on the outer gear ring of the machine body. The barrel and the reducer are close to each other, and the material is removed from the bin or hopper. The conveyor belt is sent to the end of the barrel, the material is made into small granular material in the barrel, and the material is discharged from the barrel. The outlets at the other end are together. Through the continuous operation of the machine, mass production can be realized.

3. Power saving support roller bracket is used for support. The support frame is made of high quality carbon steel, which can fully bear the weight of the cylinder. Considering the large friction between the cylinder and the supporting wheel, it is intentionally used in this part. On the one hand, more wear-resistant materials can improve the integrity and stability of the equipment.

4. The transmission device is an important part that provides the main movement for the machine. The ring gear on the cylinder is driven by the motor and reducer on the rack.

5. The shelf is made of special non deformable special channel steel, which is used for dry connection, making the transmission device of the machine more complete and stable. This is a special molding machine, which can be made by rolling materials by chemical reaction in a certain liquid. Under the action of the cylinder, through the rolling of the cylinder, the material and small particles are extruded to form a sphere.

Precautions for using granulator fertilizer:

1. Always pay attention to the temperature change of the fuselage. When touching the strip with clean hands, raise the temperature immediately. Until the silver bar touches your hand, this is normal.

2. When the bearing part of the reducer is burned or accompanied with noise, it should be shut down for repair in time and refuel.

3. When the bearing parts at both ends of the main engine bearing chamber are hot or noisy, please stop the machine maintenance and add butter. During normal operation, the bearing cavity is filled with grease every 5-6 days.

4. Pay attention to find out the operation rules of the machine; for example, if the temperature of the machine is high or low, the speed is fast or slow, it can be handled in time according to the situation.

5. When the fuselage is unstable, check whether the gap between the couplings is too tight, and adjust and loosen it in time.
