To reveal the synergistic mechanism of mechanical vibration on tailings thickening and sand discharge, based on the mechanism of tailings slurry vibration thickening, an experimental system for vibration thickening independently developed was used to conduct discontinuous thickening and sand discharge experiments under vibration. The technical feasibility of mechanical vibration to improve tailings slurry thickening efficiency and promote underflow activation and sand discharge was verified. The results show that the accumulation of tailings particles in a conical structure within the thickener is the key to improving the mass concentration of the underflow. The eccentric vibration mechanism transmits energy in a sinusoidal harmonic motion, and the excitation range of the vibrating rod is related to the slurry density and vibrator mass. A cylindrical activation region is formed around the vibrating rod during vibration, with a larger radius when the yield stress is lower and the plastic viscosity is higher. Compared with the no-vibration condition, with the increase of feeding velocity under vibration, the underflow mass concentration is increased by an average of 7.74%, the solid content of overflow water is increased by an average of 10.11%, while the increase of the overflow water rising velocity is not obvious. The research results provide a basis for the development of mechanical vibration-assisted high-efficiency thickening equipment.

为揭示机械振动对尾砂浓密与放砂的协同作用机制,在尾砂料浆振动浓密机理的基础上,依托自主研制的振动浓密试验系统,开展振动作用下非连续浓密及放砂试验,验证机械振动对提高尾砂料浆浓密效率,促进底流活化放砂的技术可行性。结果表明:尾砂颗粒在浓密机体内以锥体结构堆积是提高底流质量浓度的关键;偏心振动机构以正弦简谐运动方式传导能量,振动杆激振作用范围与料浆容重、振动器质量相关;振动过程中振动杆周围形成圆柱体的活化区域,屈服应力越低、塑性黏度越高,作用半径越大;相较于无振动条件,振动作用下随着给料速度的增加,底流质量浓度平均提高7.74%,溢流水含固量平均提高10.11%,而溢流水上升速度增加不明显。研究成果为开发机械振动辅助高效浓密设备的研制提供了依据。

为揭示机械振动对尾砂浓密与放砂的协同作用机制,在尾砂料浆振动浓密机理的基础上,依托自主研制的振动浓密试验系统,开展振动作用下非连续浓密及放砂试验,验证机械振动对提高尾砂料浆浓密效率,促进底流活化放砂的技术可行性。结果表明:尾砂颗粒在浓密机体内以锥体结构堆积是提高底流质量浓度的关键;偏心振动机构以正弦简谐运动方式传导能量,振动杆激振作用范围与料浆容重、振动器质量相关;振动过程中振动杆周围形成圆柱体的活化区域,屈服应力越低、塑性黏度越高,作用半径越大;相较于无振动条件,振动作用下随着给料速度的增加,底流质量浓度平均提高7.74%,溢流水含固量平均提高10.11%,而溢流水上升速度增加不明显。研究成果为开发机械振动辅助高效浓密设备的研制提供了依据。

To reveal the synergistic mechanism of mechanical vibration on tailings thickening and sand discharge, based on the mechanism of tailings slurry vibration thickening, an experimental system for vibration thickening independently developed was used to conduct discontinuous thickening and sand discharge experiments under vibration. The technical feasibility of mechanical vibration to improve tailings slurry thickening efficiency and promote underflow activation and sand discharge was verified. The results show that the accumulation of tailings particles in a conical structure within the thickener is the key to improving the mass concentration of the underflow. The eccentric vibration mechanism transmits energy in a sinusoidal harmonic motion, and the excitation range of the vibrating rod is related to the slurry density and vibrator mass. A cylindrical activation region is formed around the vibrating rod during vibration, with a larger radius when the yield stress is lower and the plastic viscosity is higher. Compared with the no-vibration condition, with the increase of feeding velocity under vibration, the underflow mass concentration is increased by an average of 7.74%, the solid content of overflow water is increased by an average of 10.11%, while the increase of the overflow water rising velocity is not obvious. The research results provide a basis for the development of mechanical vibration-assisted high-efficiency thickening equipment.
