Advantages of drum granulation NPK compound fertilizer production process


Drum granulation NPK compound fertilizer production process is the important equipment in fertilizer industry, which can produce special fertilizer according to demand. Compared with single chemical fertilizer, compound fertilizer particle products have more advantages. It can effectively reduce the nitrate content of groundwater, reduce the eutrophication of surface water caused by water pollution, and improve the quality of agricultural products. The ecological and environmental benefits are extremely significant.

Advantages of drum granulation NPK fertilizer production process

1. Steam is introduced into the material layer of the drum granulator to improve the temperature of the granulated material, so as to dissolve the salt of the granulated material, achieve the high liquid volume under the low moisture content to meet the liquid volume required for the material granulation, and reduce the evaporation water volume of the drying process.

2. Ammonia can be applied to the material layer in the drum as required to make the material react.

3. The inner wall of the rotary drum granulator is lined with a number of soft rubber plates or polypropylene plates, and the corresponding position of the cylinder is provided with air holes. When the inner lining changes from the bottom to the top of the cylinder, the inner lining will sag due to the self weight, so that the materials adhered to the inner lining will fall down due to the gravity, so as to achieve the function of automatic cleaning and agglomeration.

4. During operation, the operator can observe the balling of materials at any time, and take corresponding measures in time as required to ensure the normal operation of the system.

5. The raw material adaptability of NPK fertilizer production process by drum steam granulation is extensive: it can be used in combination with low solubility (procalcium chloride, calcium chloride, ammonium sulfate, potassium sulfate, potassium chloride, etc.) and high solubility (urea, ammonium nitrate, ammonium phosphate, etc.) according to the requirements, as well as some organic matter and medium and trace elements.

The product variety of the fertilizer production process: It can produce a series of products of inorganic compound fertilizer, organic fertilizer, organic (inorganic) compound fertilizer with the content of nitrogen, phosphorus and potassium from 20 to 48%.

China Tianci fertilizer machine manufacturers provides compound fertilizer equipment, organic fertilizer fermentation equipment, chicken manure grinder, organic fertilizer equipment, BB fertilizer equipment, bio organic fertilizer equipment, organic fertilizer production line, organic fertilizer granulator, drying equipment.
