参照铀矿右的磨矿和浸出同时进行的过程对该磨矿机的操作工序介绍如下:把稀硫酸加入柱形磨矿筒1,用粒度为20毫米左右的铀矿石作磨矿介质.磨矿筒1中的螺旋3借助其上部的驱动装置4转动.装入筒中的-3毫米铀矿石靠螺旋的磨碎作用进行磨矿,磨细的矿粒同稀硫酸一起由柱形磨矿筒1经矿槽8流入沉降分级槽2.进入受矿槽的粗颗粒经管5通过砂泵6返回柱形磨矿筒,以便再次磨矿和浸出.流入沉降分级槽2的粗颗粒,在其底部沉降,将其用砂泵6返回柱形磨矿筒1,这部分粗颗粒再次进行磨矿和浸出,磨细的矿粒从脱水器的溢流分离出来.现将该方法与常规方法(铀矿石用球磨机磨矿,然后用稀硫酸浸出)加以比较,列表如下:
With reference to the uranium right grinding and leaching process at the same time the operating procedures of the mill are described as follows: the dilute sulfuric acid added to the cylindrical grinding cylinder 1, with a particle size of about 20 mm uranium ore grinding media grinding The spiral 3 in the pit 1 is rotated by means of its upper drive 4. The -3 millimeters of uranium ore charged in the pit are ground by a helical grinding action which together with the dilute sulfuric acid consists of a cylindrical grinding bowl 1 flows into the settling tank 2 through the ore tank 8. The coarse particles entering the ore tank are returned to the cylindrical grinding barrel via the sand pump 6 for further grinding and leaching out.The coarse particles flowing into the settling tank 2 are collected at the bottom Settling, returning it to the cylindrical grinding bowl 1 with a sand pump 6, again grinding and leaching of the coarse particles, the finely divided particles being separated from the overflow of the dehydrator, and this method is compared with the conventional method (uranium The ore is ground with a ball mill and then leached with dilute sulfuric acid) to be compared as follows:
