Many fertilizer types are difficult to granulate. Water mixed into the powders can form bonds between powder particles that are strong enough to lock them together. However, once the water dries, the powders may fall apart. Therefore, water may not be strong enough to create and hold a bond. In such instances, Instral is able to provide you with a suitable binder that will glue all particles together to produce smooth, round granules within a narrow particle size distribution.
