本文综合叙述跳汰理论研究的现状,并根据这些理论研究提出一些改善跳汰选煤工艺的具体措施。大家知道,早期,试图从分析物体在《自由》或《干扰》条件下运动着手对跳汰过程作理论上的解释。近几年的工作中,又研究了单个颗粒在与跳汰条件相类似的加速运动液流中的行为。研究结果是获得了一系列关于颗粒运动的重要概念。稍后,又出现了《悬浮》 This article comprehensively states the status quo of the study of jig theory and puts forward some concrete measures to improve jig dressing technology based on these theoretical studies. We all know that in the early days, attempts were made to explain the process of jumpers by analyzing the movement of objects under “free” or “disturbing” conditions. In recent years, work has also investigated the behavior of individual particles in accelerating fluid flows that are similar to those of a jig. The result is a series of important concepts about particle motion. Later, there have been “suspended”
