Industrial Sifter | RHEWUM ABX

Our selective ABX sifter

With the ABX industrial sifter, we were able to improve the already very sharp dividing sifter type AWR. A CFD simulation of the expected particle flow makes it possible to design a very high dust loading up to 700 g/Nm3 and to achieve a pressure drop of only 9-12 mbar at a sharp separating classification.

Simplified Material Transport

As a top loader, one or two feeding points are enough, depending on the frame size to disperse the feed safely. The devided material then falls directly into the separation chamber which is located between the air guide vanes and the classifying rotor. This ensures that the housing is not subject to blast wear. The rapidly rotating sifter wheel with strips made of wear-resistant steel achieves the same high durability.

Unbalancing of the rotor is safely avoided by complex CNC milling. For our customers, these features mean lower operating costs (air consumption) when compared with conventional sifters. The RHEWUM ABX industrial sifter combines the functional principles of a Sturtevant sifter and an Onda sifter to a create a completely new type of air classifier

Quartz Processing

Quartz is the second most abundant mineral in the aerth's crust. The deposits deliver either solid rock or eroded sand. Grain sizes < 0.5 mm are used in the glass production, road construction, moulding sand in foundries, adhesives in the ceramic industry and feedstock for sandblasting systems. To produce iron free products, contact parts are made of aluminium oxide (alumina) or they are coated. 

Feldspar Processing

Feldspars are the most common minerals in the earth's crust. Feldspar is required for the production of glass since it contains the necessary alkali and aluminum. It is also used in the production of glazes, enamels, abrasives and welding electrodes. Potassium feldspar is the raw material for the porcelain industry. Hard-paste porcelain is characterized by a high dielectric strength. Accordingly, it is used for electrical insulators like in spark plugs. For tiles, clinker and glazes a grain size distribution of 97 % < 45 microns is sufficient. For insulators and technical ceramic, grain sizes of 90 % < 125 microns are required. These materials must be absolutely free from iron. Appropriate linings at the sifter housing and rotor have to be predetermined.
