The Advantages of Using Drum Granulation Process to Produce Compound Fertilizer

The Advantages of Using Drum Granulation Process to Produce Compound Fertilizer
1, Steam is fed into the material layer inside the drum to increase the temperature of the granulated material, so that the salts of the granulated material can be dissolved and a high liquid phase can be obtained at a low moisture content to meet the liquid phase required for the granulation of the material, while reducing the evaporated water in the drying process.

2, According to the need, ammonia can be passed to the material layer inside the drum to make the material react.

3, The inner wall of the drum is lined with some soft rubber plates or polypropylene plates, and there are ventilation holes at the corresponding position on the drum body. When the liner is turned from below to above at the same time with the drum body, the liner will sag due to the self-weight, so that the materials adhering to the liner will fall down due to gravity and achieve the function of automatically cleaning up the caked materials.

4, In the operation, the operator can always observe the situation of the material into the ball, according to the need to take corresponding measures in time to ensure the normal operation of the system.

5, Wide adaptability of raw materials: low solubility (calcium, calcium chloride, ammonium sulfate, potassium sulfate, potassium chloride, etc.) and high solubility (urea, ammonium nitrate, ammonium phosphate, etc.) and other raw materials can be used in accordance with the requirements of any combination, but also with some organic matter and trace elements.

Product varieties: We can produce various series of products such as inorganic compound fertilizer, organic fertilizer and organic (inorganic) compound fertilizer with nitrogen, phosphorus and potassium nutrients from 20~48% content.
