Research on Vibrating Spin-drier of Two-way and Half-spiral

摘要

In this paper, the structure characteristics and working principle of vibrating spin-drier of two-way and half-spiral were introduced. The dynamic characteristics of vibrating spin-drier were analyzed and the movement of materials on screen face was studied. The vibrating spin-drier was utilized for dehydration of lees and obtained more than 60% one-off dehydration efficiency. If it was used to treat with the white liquor of paper mill, it can recover paper pulp from the white liquor. It was a quite meaningful work on recycling wastes and eliminating social effects of pollution in order to protect the environment If it was adopted on the separation of mill products, the strict classification according to granularity was accurately realized. It would help reducing the load of grinding ore cycle and overgrinding, and enhancing concentrate grade.
