Separating apparatus for material classification in mechanical process engineering, has rotation body provided with product-contacting surfaces, which form cone angle between specific range of degrees with axis of rotation

摘要

The apparatus has a set of single-side or double-side supported rotation bodies (14, 20) arranged concentric to each other inside a housing (12), where the rotation bodies limit a rotation gap e.g. sedimentation gap (30), which is filled with inlet fluid during operation. One of the rotation bodies has product-contacting surfaces (38, 40), which form a cone angle (42) between 0 and 90 degrees with the axis of rotation (10), where the product-contacting surfaces exhibit a speed difference greater than 0 to each other.
