KYF series rotors and stators are mostly contracted projects for end customers, with models ranging from 2m³ to 320m³. They use high-end polyurethane raw materials. The products have high wear resistance, impact resistance, tear resistance and chemical stability, especially for copper beneficiation in non-ferrous mines. Molybdenum separation and other strong acids or alkalis (PH13-14) and accompanied by high temperature environments above 80℃ have a long service life. Currently, they have achieved very good results in various large-scale mines.
