Abstract
A mixing silo for free-flowing finely divided solid materials, in particular for powdered, fibrous and/or granular mixed material, especially polymer granules, specifically suited for mixing polymer granules, having an excellent mixing quality and at the same time a simplified and improved suitability for washing out in order to avoid cross contamination. The mixing silo may be used for homogenizing possibly inhomogeneous polymer granule batches in the form of a stream of product from a process producing polymer granules.
Claims11
