Screening machines and screen mesh

The German Rhewum GmbH is specialised in the building of static screening machines that are set up diagonally in order to prevent loads on the structure of your building. But they also produce screens with a dual frequency, horizontal multi-level screens, wet screening machines and air classifiers.

Screening machines and screen mesh

Screening machines with vibrating screen mesh (WA and WAU)

High performance vibrating machine type WA and WAU are used for classification of bulk material in the finest to medium grain size range. These machines are set up diagonally and designed in such a way that the bottom of the screen mesh is struck by cross latches that cause it to vibrate. The products distributed on top of the screen mesh jump up and tumble down past the screen mesh. The housing of these machines is completely static. This preserves the building and/or the steel structure as no dynamic loads are transmitted like they are inevitably created by conventional vibration screens. This is why these screening machines can be installed on the top floor of a production tower.

WA

In the type of machines, the latches are hit against the screen mesh by outside the screen housing rugged electromagnetic drives. This allows you to increase the vibration frequency to the maximum briefly during screening in order to clear the screen. This results in a stable optimum screening without having to stop the machine. It is also why these machines.

High performance vibrating machine type WA and WAU are often used for sticky or difficult to screen products like sugar, salt or agrochemical products

Advantages:

  • Ideal for extremely small (from 100 µm) to medium-sized particles
  • Small footprint
  • Energy-efficient
  • Replacing the screen mesh goes quick and easy
  • Available in many different dimensions
  • Food grade executions are also available

WAU

The screen mesh is struck by the high speed movement of a transversally mounted rocker shaft, located beneath the screen cloth. Out of balance motor drives rock the knocker shafts, conveying the high frequent oscillation directly into the screen mesh.

Screening machines with a dual frequency (DF)

In these machines the screening principle is based on two vibrating motors with different speeds and different operating weights. These screens are ideal for the screening of medium-sized to large particles.

Advantages:

  • Ideal for medium-sized particles (2 to 40 mm)
  • Extremely low service costs
  • Can process products to 450°C
  • Can handle large volumes (to 500 ton/hour)
  • Minimum vibration of the housing

Simple linear screening machines

The Rhewum RIUS screening machine is an economical solution for the screening of bulk goods in medium-sized to large dimensions. It operates at an angle of 15° and uses just one vibration motor.

RIUS screening machines can be adapted for use in the food or pharmaceuticals industries.

The standard machines are between 600 and 2400 mm wide and can be fitted with either screen meshes or screen plates.

Horizontal multi-deck screening machines

By using two contra-rotating out-of-balance motors generating a linear motion, the particles are thrown up and down several times until they leave the machine, so called micro throwing principle.

The modular system of our plansifter allows to superimpose up to 23 sifting decks in one sieve stack! So that machines can produce 24 different fractions.

The screen levels consist of wooden or metal frames with a screen mesh on both sides, sandwiching plastic balls that keep the mesh free of product.

Advantages:

  • Can contain to 23 different screen levels, which means that it can offer a total screen surface area of 112 m².
  • Up to 24 fractions can be generated with 1 machine.
  • Screen frames in wood, metal or stainless steel
  • Suitable for food applications
