在选矿工艺中,各种药剂的添加要求准确、调整方便,同时要求尽量减少岗位工人对药剂的直接接触。目前我国大多数金属矿选厂是采用杯式或吊斗式加药,也有部分是经改进后的虹吸式加药方式。长期生产实践证明,这些方法是不能满足上述要求的。为此,我们共同研制出活动球阀脉冲遥控加药装置。经过单点小试验和三个月的工业试验运行证明,该装置能够达到设计和生产的要求。三个多月用药量调
In the beneficiation process, the requirements for adding various kinds of medicaments are accurate and the adjustment is convenient. At the same time, it is required to minimize the direct contact of the workers in the positions with the medicaments. At present, most metal mines in our country use cup-type or bucket-type dosing, and some are siphon dosing methods that have been improved. Long-term production practice has proved that these methods can not meet the above requirements. To this end, we jointly developed the activities of the ball valve pulse dosing device. After a small single point test and three months of industrial test run proved that the device can meet the design and production requirements. More than three months dose adjustment
