Ceramic-lined cyclones are high-efficiency wear-resistant classification separators. With steel shells fully lined with 92%/95% high-purity alumina ceramic, they offer optional ZTA toughened ceramic for heavy-wear zones. The staggered seamless lining eliminates hollowing and peeling. It overcomes defects of conventional cyclones including fast abrasion, perforation, clogging and frequent maintenance, ideal for heavy scouring conditions in mining, building materials and chemical industries.
