Phosphate fertilizers

Perfect separation for phosphates

Super phosphate (SP), triple super phosphate (TSP) or double super phosphate (DSP) as well as diammonium phosphate (DAP) and monoammonium phosphate (MAP) are mainly used as fertilizers and are subject to strict quality requirements. Since phosphate fertilisers are produced in large quantities of several hundred tonnes per hour, even small efficiency deficits lead to high product losses. The aim of the screening process is to achieve high product purities at maximum throughput - and this can only be achieved by preventing clogging of the screen meshes.

Nitrogen fertilizers

Best screening results for nitrogen fertilizers

The screening tasks in the processing of nitrogenous fertilizers such as ammonium sulphate (AS), ammonium nitrate (AN), calcium nitrate (CN), potassium nitrate (KN), calcium ammonium nitrate (KAS) and urea range from lump separation to the demanding separation of product fractions as well as dust removal. Screening nitrogen fertilizer with high efficiency and throughput requires precise adjustment of all machine parts as well as a well-functioning self-cleaning system, since urea and co. tend to bind air humidity in the dust fraction and thus clog the screen cloth.

Sugar

Perfect vibrations for sugar sifting

To properly separate sugar requires the application of a high frequency directly to the material. The reason is, that sugar can become sticky even at low humidity levels and also tends to clog the sieve mesh, due to its crystalline grain shape. Screening machines with direct excitation of the screen mesh have therefore proven to be not only energy efficient, but also extremely precise. Thanks to the high accelerations, they reliably separate even finest sugars into several fractions simultaneously.

Metal Powder

Efficient separation of metal powders

Efficient separation of metal powders
High-alloyed metal powders for 3D printing (additive manufacturing/ rapid technology) should be extremely pure to guarantee a high-quality end product. Dust and agglomerates must therefore be reliably removed from the extremely fine powder during production and recycling. A suitable screening machine should not only be highly precise, but also reduce the loss of valuable product and machine downtime to a minimum.

Dry Mortar & Ready-Mix Plaster

Screening mortar precisely into several fractions

When processing dry mortar into different fractions, the fluctuating grain size distribution of the crushed limestone, as well as its tendency to clog up the screen mesh, lead to great challenges during screening. Efficient and flexible screening equipment can prevent these negative effects. On the one hand, it must be possible to individually adjust the oscillation amplitudes on each screen deck, and on the other hand, an automatic cleaning system is required to keep the screen surface open and thereby ensure throughput and product quality.
