A classifier for classifying granular feedstock has a rotary cage rotating about a rotor axis and an air-guiding system arranged around the rotary cage, wherein a classifying zone is formed between the rotary cage and the air-guiding system. In the classifying zone one or more baffles are arranged such that the torque acting on the rotary cage is increased&#x2014;for the same rotational speed&#x2014;by at least 20% with respect to an embodiment without baffles and/or the separation between the air-guiding system and the rotary cage is chosen such that the torque acting on the rotary cage is increased&#x2014;for the same rotational speed&#x2014;by at least 20% with respect to an embodiment wherein the separation of the air-guiding system is without influence on the torque of the rotary cage.

Classifier and method for operating a classifier

A milling station and a method for grinding milling material using at least one coarse grinding circuit and at least one fine grinding circuit. The coarse grinding circuit includes a classifier and a material bed roller mill. The fine grinding circuit includes a tube mill with at least two grinding chambers, a central outlet, and a divider. In some instances, at least some of the milling material from the coarse grinding circuit is subdivided in the divider and delivered to the at least two grinding chambers of the fine grinding circuit while some of the milling material is jointly discharged from the at least two grinding chambers through the central outlet.

Milling station and method for grinding milling material

A lifting wall for a tube mill which has a discharge means with lifting vanes in order to transport the material being ground to discharge openings by the rotary movement of the tube mill. The lifting vanes are disposed obliquely with respect to the radial direction so that the material being ground slides promptly to the center where it is discharged through the discharge openings still below the horizontal longitudinal central plane of the tube mill. The lifting vanes are substantially flat and bent like blades in a region of the discharge openings.

Lift wall for a tube mill

The invention relates to a rotary tube mill and to a method of comminuting lumpy mill feed material, in which at least a first and a second grinding chamber as well as a co-rotating partition disposed between the grinding chambers are used. The material ground in the first grinding chamber is divided in the partition into first and second part-quantities of mill feed material, whereby at least a part of the second part-quantity of mill feed material proceeds into the second grinding chamber and at least the first part-quantity of the mill feed material is discharged separately from the tube mill.

Tube grinder and method for comminuting lumpy grinding stock

The invention relates to a separator comprising a separator housing with an inlet spiral for separating air which opens tangentially into an annular separating chamber and is divided into a plurality of delivery channels which lie one above the other, as well as a basket-shaped separator rotor disposed centrally and with a vertical axis in the separator housing and a guide vane ring which surrounds the latter with a radial clearance. In order that this separator on the one hand has a high effectiveness of separation between oversize material and fine material and on the other hand facilitates a sufficiently broad grain size distribution of the fine material, the overall shape of the separator rotor is that of a cone which tapers downwards.
