NPK fertilizer production line is widely used in chemical fertilizer production and processing. In the process of fertilizer granulation, water is usually added to facilitate granulation, so the prepared granules need to be dehydrated and cooled to make NPK fertilizer dry. Here is how to remove water and cool down NPK fertilizer equipment.
The suction force of the induced draft fan forms a negative pressure suction force in the cooler, which absorbs the moisture and dust of NPK fertilizer particles through the suction and dust removal pipeline. At the same time, the formed wind takes away the water vapor on the surface and cools the NPK fertilizer with a certain temperature to room temperature. The generated small particles that do not meet the standards are collected through the screen of the sieving machine, and the large particles overflow after passing through the tail end. The particles that meet the standards flow out from the middle section of the screen and enter the next packaging process of the NPK fertilizer manufacturing process.
The above is an introduction on how to remove water, dry and cool in the NPK fertilizer manufacturing process.
