How to adjust moisture content of different materials before using wet granulation equipment?
As mentioned above, the moisture requirement of raw materials when using wet granulating machine is 20%-40%. But the moisture content is always different between different materials, so how to adjust the moisture of different materials? Here are some helpful suggestions.
High moisture content materials — dewatering
For high moisture content materials, such as chicken manure(75%), cow manure(>80%) and filter mud, the easiest way to reduce their moisture content is dewatering. If you have small quantity of these materials, you can stack them outside and let them dry naturally. But that will take a long time and if the weather is not good, it will take much longer time. So if you want to reduce the moisture content of raw materials faster, or you have large quantity of materials, you can choose our solid-liquid fertilizer separating machine. It can separate the extra liquid from fertilizer materials, reducing the material moisture content in a short time but cost low energy. You can also add some auxiliary materials to the materials, such as sawdust and straws, they can help the organic fertilizer materials get better composting and make the granulating more smoothly.
Low moisture content materials — adding liquid additive
If your material is already dried to very low moisture, you can add some liquid additives, such as liquid spawns. They can improve the organic fertilizer materials moisture and nutrients content. As a result, your fertilizer products will get better quality. If you think this way is too complicated, you can granulate the low moisture fertilizer materials directly by dry granulation equipment. That can also save you a lot of cost and time and bring you quality fertilizer pellets.
