Production capacity issues of compound fertilizer dryers
Thread Content
The dryer in one of the production lines in our compound fertilizer workshop has a diameter of 1800 mm and a length of 1600 mm, and the turning plates inside it are intact. I want to upgrade and increase the production capacity of other equipment; I’m not sure if the dryer is the bottleneck. What is the maximum drying capacity of this Haiyou dryer? Thank you!
The maximum output can reach 150–200 tons per day
Hehe, the model of your dryer is incorrect; it should be 16000. The production capacity should be 120-150 tons per day
The drying capacity is not only related to the size of the equipment, but also to the volume and temperature of the drying air. The length of the dryer and its rotation speed determine the residence time of the material; the longer the residence time, the more thorough the drying； The drying air volume and temperature determine the drying speed and degree, while the diameter of the dryer and its design facilitate even drying
Our factory has a diameter of 2200 mm, a length of 18000 mm, and an output capacity of around 200 tons per day
The 30,000-ton compound fertilizer production line originally designed by Nanhua was equipped with a dryer with a diameter of 1,800 millimeters and a length of 13,500 millimeters. However, during actual production it was found that the length-to-diameter ratio was a bit too small; as a result, many manufacturers (including those who produce the equipment) increased the length of this device. For dryers, there is the concept of volumetric evaporation intensity. In actual production, the drying capacity of compound fertilizers is highly dependent on the type of fertilizer.
With a diameter of 1800 mm and a length of 16,000 mm, its maximum production capacity is 50,000 tons per year. The dryer not only has a drying function but also one for secondary granulation. To increase production capacity, it is recommended to cut away 3 meters of the structure in front of the dryer to facilitate secondary granulation.

The annual production capacity of this equipment is around 30,000 to 50,000 tons (under continuous operation)
To produce general-purpose fertilizer, the cost can exceed 50,000; it’s quite difficult to achieve that. It also depends on what the granulation and cooling processes are like
It should be 120-150 tons per day
