JOEST delivered two high-performance vibrating feeder including tunnel frame, discharge chute and needle gate, each one feeding gabbro up to an edge length of 700 mm as a free stockpile discharge. Our focus was on a robust, blockage-free, wear-optimized and installation-friendly design.
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.
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.
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.
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.
SECONDARY RAW MATERIALS – RECYCLING The OSCILLA Family What is needed to screen challenging, inhomogeneous material? A special screening technology. This is what the OSCILLA Family does. Through nearly clog-free operation, products are loosened up enough to separate a fine fraction. Traditional screens are usually not capable of doing this, which is why JOEST Flip…
JOEST was awarded another contract to manufacture another large plant for screening and cooling of granulate material. The client is Melos GmbH, the specialist in EPDM-Granulat and Cable Compounds, based in Melle by Osnabrueck.
