YOUR SPECIALIST FOR SCREENING MACHINES AND CONVEYORS

Explore the world of RHEWUM



Finding the right screening machine made simple



Our machine finder will show you exactly which screening machines and conveyor
technology best match your individual requirements.



I would like to...

dry sieve wet sieve convey & distribute


POWDERS WITH THE HIGHEST PURITY.

Finest grains perfectly separated due to directly excitated screening with high
frequency drive.


CONSTANTLY PURE GRAINS.

Highest capacities with outstanding purity due to maximum machine size and
quality.


SUGAR PERFECTLY SIFTED.

Finest separations in many fractions due to high frequency vibration and
multiple screen decks.


MORTAR OF THE FINEST QUALITY.

Many fractions even for the most demanding separations due to directly excitated
screening with high frequency drive.


FERTILIZERS WITHOUT LUMPS AND DUST.

No clogging of the screen mesh due to direct excited screening with extreme
acceleration.



Applications

 * Phosphate fertilizers
 * Nitrogen fertilizers
 * Sugar
 * Metal Powder
 * Dry Mortar & Ready-Mix Plaster

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.

Vibrating screening machines with direct excitation of the screen cloth

In contrast to conventional screeners, the vibration in these screening machines
is generated by a high-frequency rocker shaft movement directly on the screen
cloth.

This allows the precise and energy-efficient separation of even the finest and
most difficult to screen materials.

Screening machines with double-frequency drive

In this particular type of drive, two unbalance motors with different speeds are
used. Upstream, a large oscillation amplitude ensures the loosening and removal
of the material, while downstream, a small oscillation amplitude at higher
acceleration ensures that even difficult to screen products are classified
accurately.

Screening machines with linear vibration

Linear vibrating screens are a cost-effective alternative to directly excited
screening machines. They can be supplied with several screen decks on request
and are available in tailor-made special designs. Their low-maintenance
unbalance motors and good accessibility through large inspection openings
simplify maintenance tasks.

Screening machines for wet classification and dewatering

By overcoming cohesion forces, our high-performance dewatering screens achieve
maximum dewatering of solid particles from suspensions with optimized residual
moisture content for particles down to less than 1 mm. In wet processing, the
precise screening technology ensures efficient disagglomeration of the material
and thus optimum separation of coarse and fine material.

Conveyor technology: Conveying systems, feeders and distributors

We offer product-friendly, customized conveyor technology for the transport and
dosing of bulk materials, dividing them into uniform product streams or feeding
downstream machines.

Depending on the selected design, it is even possible to design conveying and
distribution devices with integrated pre-screening.

THE SCREENING MACHINE MANUFACTURER WITH A PASSIONATE COMMITMENT

Believe it or not – for over 70 years it has been our objective to manufacture
the best screening machines in the world! For our customers, we always aim to
deliver the most effective screening machines for their specific task. Of
course, we consider our customers’ technical and commercial constraints, and
adjust each screening machine exactly to their wishes and requirements.

RHEWUM screening machines are “Made in Germany” or more precisely “Made in
Remscheid” – for this reason it is no surprise that we are not the cheapest
manufacturer of screening machines, but our sophisticated clientele appreciates
our established quality. Still not convinced? We will test your material in our
technical center and demonstrate to you the performance of our screening
machines, live on site! Clear, committed answers instead of cryptic promises are
what you can expect from RHEWUM.
