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 be generated because this wet screening machine is perfectly suitable for fine and finest solids. It is particularly specialized in separating suspensions of less than 1 mm (0.04 inch) or dewatering them. Usually, this screen achieves a dewatering rate that is about half the rate of a normal linear vibrating screen. This saves the customer expensive energy costs for further drying, as the product is already very well dewatered after screening.
