Application practice of super wear-resistant nested hydrocyclone in Linhuan Coal Preparation Plant<br>Li Xiaofei<br>(Linhuan Coal Preparation Plant of Huaibei Mining Co., Ltd., Huaibei 235141, Anhui)<br>Abstract: in view of the existing problems of heavy medium cyclone, such as poor wear resistance, frequent material leakage, poor on-site operation environment, continuous production accidents in shift, large index fluctuation, heavy workload of cyclone replacement and maintenance, the reasons for poor wear resistance are analyzed from the wear-resistant materials, structural characteristics and fluid flow characteristics of the original heavy medium cyclone, Through the application of super wear-resistant nested cyclone with advanced material and structure, the leakage phenomenon of dense medium cyclone is reduced, and the continuity of production is ensured.<br>Key words: dense medium cyclone; wear-resisting; Material consumption<br>
