国内外一般都在采金船圆筒筛内安装一套碎散装置来提高矿砂的碎散效率,但我国引进的MTE采金船上的圆筒筛未安装这种装置,只用高压冲洗水来碎散矿砂。圆筒筛内是否必须安装一套纵向附加物、环形堰板等?本文就一些文献料资和生产实践,对碎散装置,高压冲洗水对于矿砂的碎散效率问题,作一粗浅的探讨。 At home and abroad, a set of crushing devices are generally installed in the cylinder screen of the gold mining vessel to improve the crushing efficiency of the ore. However, the cylinder screen on the MTE gold mining vessel introduced in our country is not equipped with such a device and only high pressure flush water Broken ore. Whether it is necessary to install a set of longitudinal attachments, annular weirs, etc. in the cylinder screen? In this paper, some literature materials and production practices, on the fragmentation device, high pressure washing water on the ore dispersion efficiency, make a superficial discussion.
