US producer of plastic granules relies on RHEWUM wet screening machine
In his production chain an American manufacturer will no longer use two machines for screening his plastic granulate, but only one: the Rhewum wafl with two screen decks. Pavement markings have been used since the beginning of the 20th century. Today they are part of the modern street scene and without them we would sometimes lose orientation. The line markings create a clear and safe traffic guidance. The products of the world’s leading North Carolina-based manufacturer are not only used on roads and highways, but also on taxiways, take-off and landing runways, parking lots, intersections and in all types of commercial, construction, government, industrial and architectural environments. So these markings help drivers, pilots and pedestrians to move safely in the right direction. The exact process of producing road markings will not be discussed in detail at this point, as it is quite complex. However, plastic granulate is processed in the production of road markings, that must be dewatered. With the help of the Rhewum wafl the water can be perfectly separated from the product and a low residual moisture of approx. 8 percent can

RHEWUM develops noise control solution for screening machines To reduce the noise emission of your screening machine RHEWUM now offers an innovative sound insulation cover.
RHEWUM develops noise control solution for screening machines
To reduce the noise emission of your screening machine RHEWUM now offers an innovative sound insulation cover. Usually screening machines are not the quietest machines in the production chain. Due to impact bar movements the screen cloth is excited to high frequency vibrations. This, in combination with the product to be screened, causes noise emissions which sometimes have to be reduced. The sound insulation tarpaulin for screening machines provides a quick and uncomplicated solution to this problem. The sturdy, custom-made tarpaulin is covered with an acoustic membrane which damps the sound and absorbs sound energy. The sound power level of the machine can be reduced by 8 dB by attaching the sound-insulating tarpaulin, which corresponds to approximately halving the perceived noise level. The tarpaulin is flexible and easy to bend - which in turn ensures simple and quick installation on the machine. Important maintenance openings remain easy to operate, as the tarpaulin can be opened at the crucial points using robust zips. The short implementation time and the cost-effective

New vibration motors: The GeniusDrive now up for delivery
RHEWUM will also build the vibration motors in-house in the future. The motors are compatible. We have made it our ambition to manufacture the best screening machines in the world. To achieve this, we also need the best vibration motors in the world. We have focused our in-depth expertise in screening and motor technology to make energy-efficient vibration motors even more reliable and stable, so that our customers can rely on a trouble-free production process. The result is our GeniusDrives. All key parts of the GeniusDrive are manufactured in Germany. Each of our self-produced unbalance motors is tested under full load before it leaves the production line. It is of utmost importance to us that the motors are perfectly matched to our machines and the needs of our demanding customers. Technical and other information can be found on the website of the same name. Order today and we promise you a fast delivery.

Company extends production of cat litter with RHEWUM screening machines
Company extends production of cat litter with RHEWUM screening machines
In order to increase the plant capacity for the production of cat litter, an international oriented company for raw materials built a second production line, in which RHEWUM screening technology was used once again to ensure product quality. A new, modern and automated high-bay warehouse ensures better logistics and efficient transport organisation to Europe as well as to the United Arab Emirates and Australia. After the discontinuation of mining in 1992 the potash factory in Lower Saxony was converted for a cat litter production using the already existing infrastructure. As a result of the success and increasing demand in the sales network with other companies, the second production line will increase capacity by 40 percent per year in the future. For this purpose further proven screening machines of Rhewum gmbH were designed, ordered, delivered on schedule and installed into an existing building. The commissioning at the end of 2019 was successful without any problems

High performance screen aggregates for the asphalt industry RHEWUM supplied various asphalt mixing plant operators with new DF screening units for the season.
High performance screen aggregates for the asphalt industry
RHEWUM supplied various asphalt mixing plant operators with new DF screening units for the season. In general asphalt is a mixture of minerals and bitumen as binder. In asphalt mixing plants asphalt mixes are produced by a thermal mixing process of mineral rocks, filler (rock flour), binder (bitumen) and if necessary additives for different requirements. Screening machines are required to classify the mineral rock for these processes. Like for example the Rhewum double Frequency Screening Machine (short DF) - a high performance unit for screening in the medium and coarse grain range. The drive principle of the DF is based on the use of two vibration motors with different speeds. The product is loosened and mixed at the screen inlet due to the large vibration amplitude. The higher frequency at the screen outlet causes even difficult to screen material to be screened due to the higher acceleration. By changing the direction of rotation of the vibration motors at the inlet and outlet, the transport speed of the product can be changed. Advantages include good accessibility

Screen Applications in the Glass Industry RHEWUM Screening Technologies for Glass Processing
Screen Applications in the Glass Industry
RHEWUM Screening Technologies for Glass Processing Glass can be found in almost all areas of daily life. Starting in the construction industry, through telecommunications, household, food, automotive and aircraft construction to optics. The ever-increasing demands on technical glass can only be met by using ever more precise basic materials such as quartz sand and soda. But also a variety of glass products such as glass wool, glass balls or other waste glass only become a saleable product through classification. RHEWUM screening machines are also used in the processing of glass. Glass production The technique of glass production has been known for over 6,000 years. It has been continuously refined until today. Since then, glass has been used in a wide range of applications and has become a versatile material. In general, every glass contains one or more glass-forming oxides. The most commonly used are silicon dioxide (SiO2), i.e. quartz sand, but also boron trioxide and phosphorus pentoxide. Classification in basic
