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.
Claims10
A mixing silo comprising a cylindrical container with a conical outlet and
- i. a plurality of vertically arranged partition walls connect a central middle pipe, running in the direction of the longitudinal axis of the cylindrical container, and a wall of the cylindrical container to one another, so as to produce a plurality of chambers (7) separated from one another, the chambers being fillable with granules from above and each having an emptying opening at a the conical outlet for removal of the granules, wherein all the emptying openings open out into the conical outlet and the emptying openings cannot be closed off;
- and
- ii. a filling device configured to distribute the granules into all the cylinder chambers (rotary tube distributor).
