超细全尾砂深锥动态絮凝浓密试验 USTB

The solid mass fraction of the underflow of the deep cone thickener increases with the increasing mud height, and this process conforms to the DoseResp function. This growth process can be divided into three stages: (1) slow growth (mud height 1–4 m), (2) rapid growth (mud height 4–7 m), and (3) basic stable (mud height over 7–8 m).In the practical thickener cone systems, the underflow concentration is hard to measure through physical sensors while there exist the high cost and significant measurement delay. This paper presents a novel and deeply efficient long short-time memory (DE-LSTM) method for concentration prediction in the deep cone thickener Underflow concentration prediction based on improved dual

A Short History of Deep Cone Thickener Development

deep cone thickener that is a third of the diameter. Bagatto (1989) had compared raked thickeners with rakeless ones and had also determined that the underflow could be controlled using the torque signal. In 1973, Robinsky pioneered the use of thickened tailings disposal, which has gained steadily in popularity.Deep cone thickener (DCT) is key equipment in cemented paste backfill (CPB) technology. However, rake blockage occurs frequently in DCT during the dewatering process of the unclassified tailings being thickened from dilute slurry to thickened tailings or paste. Rake blockage has disastrous effects on the CPB operation. In order to A Theoretical Model for the Rake Blockage Mitigation in Deep Cone
