Interview Dr. Marcus Wirtz – AT Mineral Processing Europe

Half Time reached!

For our long-standing customer, Dyckerhoff company, we have now exchanged JOEST tube type feeder at two star distributors for silo loading during the winter overhaul for the 4th year in a row, thus reaching the halfway point of the overall project.

Classifying & Dewatering with JOEST

JOEST vibrating screens are essential equipment for classifying and dewatering contaminated soil. Four vibrating screens were specifically designed for our long-time Belgian customer. In addition to the three dedicated dewatering screens, a two-deck screen for classifying and dewatering was also delivered earlier this year. A unique feature is the upper deck, which has various inclinations. These different inclinations ranging from 5 to 0 degrees have a positive impact on the final screening outcome. With steep throw angles and high accelerations, very low residual moisture levels are achieved. Another crucial aspect is the special PU screen panels that contribute to efficiently dewatering the soil and achieving the desired classification and dewatering effects.

31-meter Vibrating Conveyor System

Plant for transporting and processing waste incineration slag. PreZero Energy in Roosendaal produces electrical energy and district heating by incinerating domestic and industrial waste. In addition to the energy extraction, metals and recyclable building materials are also won from the incineration process. These materials are extracted right after the thermal process as part of the so-called waste slag and are then transported away and preprocessed. Well known characteristics of this material compound are its abrasiveness and chemical aggressiveness in combination with a high moisture content.

Largest Vibrating Screens for the aggregate industry

Back in 2008 and 2009, JOEST delivered a total of eight large, 3,070 x 7,000 mm, Linear Vibrating Screens to their client Norsk Stein in Jelsa. Norsk Stein is Norway’s leading producer of gravel and stone materials, producing more than 15 million tons of aggregates for the entire European market. The JOEST Screens equip the secondary crushing plants with two parallel production lines for extremely abrasive granite. At a total capacity of 3,000 t/h, the material is classified from 125 mm down to 5 mm. In 2014, the plant was modified to focus more on the production of armourstone. An increased feed grain size and screen cuts of up to 220 mm became necessary. To achieve these new demands, one Linear Vibrating Screen was exchanged for a Double-Shaft Elliptical Motion Screen.
