Rotary vibration of tower separator membrane separation in the flow of equipment developed on the basis of a new type of slime separator, with the principles of advanced, high efficiency, large capacity per unit area and so on.Vibration by rotating the paper sorting machine tower structural analysis and experimental study Gongyi parameters obtained in the crude slime of the device to sorting area with some effect, but there are many aspects for us to study and improve Key words: gravity separation；flow membrane separation; slime; rotating tower vibration sorter； 目录 摘要……………………………………………………………….……Ⅰ ABSTRACT……………………………………………………………….Ⅱ 一、研究背景………………………………………………..…..1 二、设备概况……………………………………..……..5 2-1 旋振塔式分选机结构…………………………….……5 2-2 工作原理…………………………………………...…6 2-3 各部分功能简介……………………………………....7 三、实验研究……………………………………………...……8 3-1 实验器材…………………………
