Tackling tailings safely and sustainably
Alfa Laval decanter centrifuges are a proven, efficient solution for large-scale dewatering of tailings and removing the finest particles that conventional solids control equipment is unable to deal with. They offer a cost effective, sustainable and, above all, safe solution to manage tailings, acting as a complement to traditional separation systems such as thickeners, sedimentation basins and filters or replacing old systems altogether.
技術工作原理
阿法拉伐P2和P3臥螺離心機專門用于將礦漿和尾礦分離成固相和液相，分離在配備螺旋輸送機的水平圓柱形轉筒內進行，給礦漿通過固定的進料管進入轉鼓，然后在給礦區平穩加速。高達 3,500 G 的離心力將固體顆粒從液體中分離出來，固體堆積在轉鼓的內表面。
輸送機的旋轉方向與料碗相同，但速度不同，這給固體顆粒帶來了軸向推力，傳送帶將這些顆粒向碗的錐形端輸送。固體顆粒通過固體排放口離開貯料碗進入機殼，而澄清液體則流過可調節的板壩或動力管進入機殼離開貯料碗。

Tailing dewatering - Breaking new ground in mining and minerals
Alfa Laval decanters revolutionize coal mine tailings management strategy.
The Rix’s Creek coal mining operation, part of the Bloomfield Group, set out to improve its onsite coal tailings management as part of its sustainability strategy to reduce water and energy consumption and minimize the surface footprint of waste handling processes.
After evaluating various technologies, Rix’s Creek engineers installed an Alfa Laval decanter centrifuge to dry coal tailings.
The result? Savings in capital expenditures as well as, about 90% recovery and re-use of the process water.
