Definitions
- the invention relates to a sifter for sifting lumpy feed and a method for operating a classifier.
- the material In grinding systems in open mode, the material is once passed through the grinding plant and then has the desired product properties in terms of fineness and particle size distribution.
- a significant increase in the efficiency of the grinding system could be achieved through the use of classifiers, whereby the material to be ground is driven in a mill-classifier circuit.
- the fresh food can be abandoned before or after the mill.
- An oversize, as in the open mode, is reduced and the product properties can be better adjusted.
- ball mills, vertical and horizontal roller mills, stirred ball mills or high-pressure roller presses are used as mills in the cement and mineral sectors. The throughput of these mills is limited and independent of the separation result in the classifier nearly constant. In order to increase the amount of finished goods per hour, this can be done when using these mills therefore only on an improvement of the sighting.
- a better sighting has the consequence that less fines (Fertigut) is in the coarse material of the classifier and accordingly the proportion recirculated to the mill is reduced, so that a correspondingly larger proportion of fresh material in the mill can be processed.
- the classifiers have evolved from a static to a dynamic airflow sighting. That is, the rotation was added to the air flow and gravity.
- the usual structure consists in that an air guidance system is arranged around a rotating rotor cage so that a viewing zone is formed between the rotor cage and the air guidance system.
- the feed to be viewed is introduced either together with the classifying air flow through the air guidance system and / or from above directly into the viewing zone.
- the invention is based on the object of improving the visual efficiency of classifiers with a rotor basket rotating about a rotor axis and an air control system arranged around the rotor basket.
- the method according to the invention for operating a classifier for sifting lumpy feedstock has the following method steps:
- Abandonment of the chunky feed into the viewing zone wherein in the viewing zone one or more internals are arranged such that increases the torque acting on the rotor cage - at the same speed - by at least 20% compared to a version without internals and / or the distance of the air control system to the rotor cage is selected so that the torque acting on the rotor cage - at the same speed - increased by at least 20% compared to a version with a distance of the air control system without affecting the torque of the rotor cage.
- the sifter according to the invention for sifting lumpy feed has a rotor cage rotating about a rotor axis and an air guiding system arranged around the rotor cage, wherein a viewing zone is formed between the rotor cage and the air guidance system.
- a viewing zone is formed between the rotor cage and the air guidance system.
- one or more internals are arranged such that the torque acting on the rotor cage - at the same speed - increased by at least 20% compared to a design without internals and / or the distance of the air duct system to the rotor cage is selected so that on the rotor basket acting torque - at the same speed - by at least 20%> compared to a version with a distance of the air duct system without influence on the torque of the rotor cup is increased.
- an inhomogeneous flow is selectively generated in the viewing zone, at least in individual areas. It is therefore consciously away from the hitherto pursued concept of a homogeneous flow as possible and could surprisingly find in the experiments on which the invention is based, that a more effective sighting takes place precisely due to the inhomogeneous flow.
- the bypass so the proportion of the fine material, which is rejected by the classifier together with the coarse material is reduced.
- the above classifier or the associated method is also advantageous if the classifier is to produce two finished products of different grain size, since the fine material and thus the higher-quality proportion is obtained in a correspondingly larger amount.
- the increase in efficiency of the classifier is based on the fact that the installations in the viewing zone or the air guidance system placed closer to the basket cause an increased deagglomeration of the feed material to be viewed. Due to the built-in or narrowed viewing zone also flow bottlenecks, which can increase the kinetic energy of the feed particles by a multiple. As a result of the drag forces of the rotor-basket rotation and the internals, the feed material is subjected several times to a deagglomeration and again to a sighting on the rotor cage, whereby the particles can disintegrate and be more effectively sighted.
- the lumpy feed material to be inspected can be supplied together with the classifying air through the air guidance system and / or at least partially separately from the classifying air of the classifying zone.
- the rotor cage may be cylindrical, frusto-conical and / or stepped.
- the largest diameter of the rotor cage should be at least 0.5 m, preferably at least 1 m. But there are also rotor baskets with diameters of up to 8 m or more conceivable.
- the distance of the air guidance system to the rotor is preferably less than 60 mm, preferably ⁇ 55 mm, most preferably ⁇ 50 mm.
- the through the internals and / or the distance of the air control system to the rotor basket-related torque increase is preferably at least 25%, with values of at least 30% or at least 50%> higher bypass reductions are possible. In the experiments on which the invention is based, it has also been shown that torque increases of at least 75% or even at least 100% bring about an even greater increase in efficiency.
- the distance of the control system and / or the internals to the rotor cage is adjustable, so that you can park the system targeted to the available drive power of the rotor cage.
- the air duct system consists of a plurality of baffles (vanes and / or Bo genschaufeln and / or Rieselblechen), wherein the arranged in the viewing zone internals are attached to some or all of these baffles. It is also conceivable that the internals are formed by end portions of some baffles, wherein the end portions protrude into the viewing zone. The internals may extend over the entire or only part of the axial extent of the rotor cage and may be aligned parallel or not parallel to the rotor axis.
- the rotor cage has additional, projecting into the viewing zone and mitrotierende with the rotor basket components for supporting generating an inhomogeneous flow field in the viewing zone.
- the rotor basket rotates about a vertically oriented axis.

It can be seen that the torque M decreases with increasing distance a of the air guidance system from the rotor cage and the air guidance system exerts no influence on the torque from a certain distance. In this state, the torque M in Fig. 13 is given as 100%.
- the shaded area 24 shows the known from the prior art area, according to which the distance of the control system is more than 60 mm to the rotor cage.

- Particularly preferred is a range of more than 175% or even more than 200% of the torque over a design without internals and / or with a distance of the air control system without affecting the torque of the rotor cage.
- the bypass T m i n , norm is the minimum degree of separation of the separator curve of a classifier.
- the bypass is at a particle size smaller than that at which the separator section is located (see common practice of trump evaluation of separation curves).
- the bypass thus represents a measure of the proportion of the fine material, which is rejected by the classifier due to agglomeration with the coarse material.
- the bypass Tmi n , norm [%>] is usually normalized to compare the number of classifiers to a circulation factor (ratio of classifier input to fines) of 2, in order to eliminate influences of raw material and milling process of bypass value.
- the classifier 100 and the mill 200 is operated as Umlaufmahlstrom, wherein the coarse material 600a is returned to the mill 200 and there further comminuted together with fresh material 300.
- the fresh food can also be given to the classifier first.
- a ball mill, a vertical and horizontal roller mill, a stirred ball mill or a high-pressure roller press may be considered as the mill 200.
