A centrifugal classifier including a classifier housing having at least one coarse material outlet and a classifier wheel, revolving in the classifier housing. The classifier wheel is comprised of a classifier drum and a classifier wheel shaft forming the axis of rotation of the classifier drum. A guide member is arranged near the coarse material outlet, at a set distance from the inner jacket surface of the classifier housing section surrounding the classifier drum. The guide member is configured such that classifying material flowing along the inner jacket surface at a radial distance less than or equal to the set distance circumvents the guide member and is discharged into the coarse material outlet and classifying material flowing along the inner jacket surface at a radial distance greater than the set distance is deflected in a radially inward direction toward the classifying drum.

Centrifugal separator comprising special separator wheel

A centrifugal separator including a separator housing and a separator wheel revolving in the housing. The separator housing has an inlet for material, a coarse material outlet, and a fine material outlet. The wheel is formed by a drum and a wheel shaft, which supports the drum and rotates around a horizontal axis. The circumferential jacket surface of the drum is interrupted such that it sets the material to be separated, which hits the drum on the outer jacket side, into rotation during operation and the separation air flows through it in the radially inwards direction. The fine material outlet is arranged on the end of the drum and fine material is discharged from the interior of the drum into the fine material outlet via the free front face of the drum. The wheel shaft consists of two parts, which are not directly connected to one another in a supporting manner.
