Air separator CTC

metalverticalclassifier

The CTC fine separator series was developed based on the latest classifier technology findings (fourth generation). CTC fine separators are excellent for classifying metal oxides, mineral fillers (CaCO3, talcum, mica, dolomite), cement, slag, and raw meal. Experts also considered other crucial steps, such as coordination with the grinding unit and design of the corresponding peripheral equipment (material handling, air and gas technology, product transport). This series was designed to optimize production, operating, and maintenance costs, which was achieved by combining rotor geometry and an improved flow design in a new way. This leads to more efficient classification, low bypass of fines, and therefore lower energy consumption for pulverization and classification. The classifiers are designed and their strength is optimized through FEM simulations, vibration tests, and modal analyses. This does not only guarantee the lowest possible maintenance costs, but also streamlines manufacturing costs. Due to the specific design of each series, the critical rotor speed exceeds the maximum operating speed by far. The newly developed CTC series (for fine industrial minerals d98 = 25–30 μm) has an innovative design that guarantees peak production with the finest quality and optimized operation costs. The classifier’s modular design enables CEMTEC to create excellent customized solutions for their ball mills and vertical mills. Because of the modular design, air can also be supplied from below, in combination with CEMTEC’s vertical roller mill series or as a stand-alone solution for customized applications.
