Granulate dryer is important in the fertilizer production line. Our granulators adopt wet granulation and dry granulation. Wet granulation increase pellets’ moisture to 50%-60%, but dry granulation not. As there is no need to add water etc. to improve moisture during the granulation, its moisture is about 20%-30%. Therefore, fertilizer pellets after dry granulation can package directly. However, pellets made by wet granulation must go through dryer to low down the moisture to the package standards: 20%-25% moisture.
Thus, a dryer is important for you, especially you have the granulating machines which adopt wet granulation, such as, new type organic fertilizer granulator, drum granulator, and disc granulator etc. Here is more information about dryers for your reference.
What Types of Drying Machine Can You Choose?
In our factory, you can choose rotary drum drying machine accordingly. We mainly designed drum drying machine, and there are six models of this type in our factory.
The dry wet material is sent to the hopper by the belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe of the feeding machine of the hopper. The inclination of the feeding pipe should be greater than the natural inclination of the material so that the material can flow into the dryer smoothly. The dryer drum is a rotating drum that is slightly inclined to the horizontal line.
The material is fed from the higher end, and the heat carrier enters from the lower end, and contacts with the material in counter, or the heat carrier and the material flow into the cylinder together. With the rotation of the cylinder, the material moves to the lower end under the action of gravity.
When the wet material moves forward in the barrel, it receives heat from the heat carrier directly or indirectly, so that the wet material is dried, and then is sent out at the discharge end through a belt conveyor or a screw conveyor.
Granular Drying Machine’s Installation is Flexible According To Your Needs
We can design an ideal layout of fertilizer production line about granulation machines and dryer equipment. If you have other ideas and requirements, we are always love to accept the reasonable advice. As our company has the strength and technology to satisfy your various needs. In this case, you can choose to install the granulate dryer for fertilizer pellets according to your production needs.
We have knew that a dryer in the production line is to dry the granulated pellets to the package standards. However, if you would like to decrease the raw materials’ moisture at first, and then use our flat die granulating machine to make pellets, and have doubts whether it can put into use. Then you can contact our customer service, and they will give you the accurate answer. Generally, it will work, but we still need to know more information about kinds of raw materials, factory area, and types of energy power etc. to give you the most accurate answer.
