Abstract
An apparatus and method for uniform granulation is disclosed. The method involves the use of an initial feedstock having particle size of -150 mesh and 90% or greater particle size of 200 mesh. The feedstock may be contacted in a pan granulator which includes a minor amount of nucleating material of about -35 mesh. Binder is introduced into the pan granulator to progressively layer the feedstock material onto the nucleating to form a final product having a size distribution -8 mesh to +4 mesh. The method is designed to be interruptible and is particularly useful for forming granules having a plurality of layers of differing material. The method has marked improvement over the prior art methods since a particularly fine granule can be formed in a relatively expedient process to result in a granule having high commercial value and high break strength. These factors are achievable in addition to 100% product usage with no waste.
