美国一家生产水压驱动式排液泵的公司生产出了一种ＫＳＰ80排液泵 ,用于铂矿将高浓度回填料输往采石场。连续运转的双轴强制混合器产生固体含量为 77%的由水泥、尾矿和水混合而成的糊膏。通过混合器上转矩反馈自动添加物料使糊膏中固体含量始终保持在 1%以内。这种ＫＳＰ80排液
A US-based company that produces hydraulically driven drain pumps has produced a KSP80 drain pump for transporting high concentrations of backfill to the quarry in platinum mines. Continuous operation of the biaxial forced mixer produces a paste made of a mixture of cement, tailings and water with a solids content of 77%. The amount of solids in the paste is always kept within 1% by automatically adding material through the torque feedback on the mixer. This KSP80 drained
