Screening Technology in 104 Languages on corporate website Rhewum

While others are just screening, we are seeing the big picture. Since its foundation RHEWUM has always been looking for the perfect solution. As the leading company in the field of industrial sieving technology we do not just provide screening machines, but the optimal separation of bulk materials that is perfectly tailored to your needs. We can achieve this through customized technology that offers unrivaled reliability with the highest service and product quality.

Announcing the launch of our latest innovation, the RHElite high-precision screen, a groundbreaking solution designed for the most demanding industrial applications. Engineered with a perfect blend of steel and Carbon Fiber Reinforced Polymer (CFRP), the RHElite sets new standards in the screening of finest high-end products. How is it possible to build such a machine? Due to the anisotropic behavior of certain types of GFK (glass-fiber-reinforced plastic), where mechanical properties such as strength and stiffness vary depending on the direction, the machine can be specifically optimized for certain load directions. This allows for more efficient and targeted use of materials. Optimized for Unmatched Precision Screening The RHElite is engineered to perform with unparalleled precision, making it the top choice for the screening of the finest high-end products. Its advanced technology ensures sharper separation of fine particles, significantly enhancing the quality of your output. The sophisticated design and superior performance of the RHElite outpace traditional models, offering a more energy-efficient solution that meets

Learn how RHEWUM’s screening technology optimizes the separation of glass fiber reinforced polyamide beads to increase quality and efficiency in material processing. Introduction The industry is continuously faced with the challenge of processing materials not only efficiently and economically, but also meeting the quality requirements of end products. A special focus is on the processing and separation of plastics, especially glass fiber-reinforced polyamide spheres (PA GF). These specialty plastics, enriched with glass fiber, offer improved mechanical properties and are therefore in high demand in many technical applications. Efficient sieving of these materials is crucial for the purity of the end product and thus for the quality. In this context, RHEWUM sieving machines play a central role. Technological progress in sieving technology RHEWUM’s sieving technology is based on long experience and continuous development to meet the specific requirements of different materials. Particularly in the separation of glass fiber-reinforced polyamide spheres, it is essential to achieve precise separation to secure the desired material

As the world gravitates towards sustainable solutions, the recycling of lithium-ion batteries has emerged as a crucial element in our green future. Central to this process is the handling of ’black mass,’ a complex substance that presents unique challenges in recycling and especially screening. Understanding Black Mass Screening Black mass, primarily composed of valuable metals like lithium, cobalt, and nickel, also contains graphite, which complicates the recycling process. Screening is essential at different stages, such as removing larger metal foils during black mass creation and purifying black mass by removing materials like aluminum and copper. The primary challenge arises from the large fraction of fine graphite particles in black mass, which can be as small as 10 µm. The nature of fine graphite as a sticky, greasy material complicates the process. It tends to adhere to other particles, making separation difficult. Additionally, graphite’s propensity to clog meshes and form agglomerates that move as cakes across screens reduces screening efficiency. Traditional screening methods often struggle

Sugar is usually offered in different particle sizes depending on sales requirements. The requirement: Fifteen different particle sizes A customer approached RHEWUM with a request to offer fifteen different particle sizes for sugar products. The customer supplies a number of different sugar processing industries, including companies as diverse as beverage manufacturers and bakeries. RHEWUM was therefore asked to provide screening machines that could process the feed material in three stages from very fine classifications to rather coarser separations in the final stage. Versatile high-performance machines Machines of the RHEsono type were used for the fine separations. Here, a high-frequency beater bar movement discharges the screenings at right angles from the screen mesh - the inclination of the mesh enables the screenings to be transported over the screen. For the two stages with coarser separations, smaller machines of the RHEmoto type were used. Maintenance-free unbalanced motors located outside the screen housing transmit high-frequency vibrations via oscillating axes directly into the screen

Foundries face the challenge of efficiently separating casting molds and sand cores from cast metal parts. This sand must be recycled. What is Cast Shakeout and Sand Shakeout? After the molten metal is poured into the molds and solidified, these molds need to be removed to obtain the finished castings. This process is called shakeout. Cast Shakeout specifically refers to the separation of casting molds or cores from the cast metal parts. Cores made of materials such as ceramics, which have a different composition than the surrounding sand, are often used. To obtain the final shape of the casting, these cores need to be removed. On the other hand, Sand Shakeout involves the separation of sand molds and sand cores from the cast metal parts. Sand is commonly used as a molding material in the foundry industry. Once the metal is cast and solidified, the sand molds need to be removed to expose the castings. RHEtrans for efficient Cast Shakeout RHEtrans by RHEWUM is an oscillating chute with an unbalanced drive, known for its economical conveying capability and robust, reliable construction. RHEtrans
