摘要： A hot die face granulation of melt-type materials, such as polymer melts, which pass through the melt channels of a die plate and are divided into granulate while still hot on the outlet surface. The die plate includes a die plate body having melt channels, which pass through the die plate body and feed onto an outlet surface distributed in ring-shaped formations, on which outlet surface the exiting melt strands are divided by a rotating blade, a granulation head comprising a die plate of this type, as well as an underwater or water ring granulator comprising a granulation head of this type. The invention also relates to a method for producing a die plate of this type.
