Screening Machines for Lithium-Ion Battery Recycling
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

 Efficient separation technology for foundries Foundries face the challenge of efficiently separating casting molds and sand cores from cast metal parts. This sand must be recycled.
Efficient separation technology for foundries
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

Sand extraction through mobile processing Due to the flourishing construction industry, sand is now the second most traded raw material after water. But suitable sand resources are limited. RHEWUM has developed a solution to produce sand from widely spread gravel right next to the customer.
Sand extraction through mobile processing
Due to the flourishing construction industry, sand is now the second most traded raw material after water. But suitable sand resources are limited. RHEWUM has developed a solution to produce sand from widely spread gravel right next to the customer. A flourishing construction industry without sand is unthinkable. According to One Stone Consulting, around 10 to 15 billion tons of building sands are required worldwide each year (1). In addition, we need industrial sands, for example for fracking or the glass industry. This corresponds to a per capita sand consumption of about two to eight tons per year, so that a total of 40 to 50 billion tons of sand and gravel must be extracted. This makes sand the second most traded raw material after water (2). Since the demand for sand is growing faster than suitable sand resources can be found, sand is instead produced from gravel or transported over long distances. This is not environmentally reasonable. RHEWUM has developed a solution to process sand mobile and therefore directly on site. THE RAW MATERIAL Quartzite sand is mainly used in the construction industry. It consists of silicon dioxide (SiO2). The great hardness of the material (7° according to Mohs) is an advantage.

Building materials - sieving with finest separations
Calcium carbonate is a material that originated from the remains of single-celled sea creatures over millions of years of Earth’s history. Today, it is the basis for a range of commonly used building materials, including limestone and dolomite. Finest separations up to 0.1 mm A British customer discussed with RHEWUM ways to renew an aging installation for processing calcium carbonate. Several existing sieving machines and sifters were to be replaced. Fine separations up to 0.1 mm were performed. Setting vibration during operation Machines with direct excitation of the screen fabrics were planned as the machine type. Drives for the decks on which coarser separations were to be performed were unbalanced motors. The decks for fine separations were equipped with oscillating heads that allow the vibration to be changed during operation via thyristor controllers. The machine types of choice were then RHEsono, RHEmoto and RHEfino as a combination of both types. For the task of feeding the material onto the machines, RHEside feeders with lateral feeding were used. Customer requirements were met With
