链斗式采金船的受矿过程是,挖斗链绕斗桥的上、下滚筒转动来采掘、提升矿砂,同时不断地将矿砂卸至受矿装置处,然后进入选别系统.链斗在卸矿时,由于高差等原因的限制,以及斗桥随着挖深的改变,其角度变化的影响,往往在卸矿时漏矿现象是很难避免的,据查定某100升链斗式采金船和150升链斗式采金船漏矿量分别为原矿量的5%～8%.当挖掘的原矿砂含泥量较多、并胶结性很强时漏矿量就更为严重,此数值往往超过10%以上.
Bucket-type gold mining vessels by the mining process is digging bucket chain around the bridge of the upper and lower drum rotation to excavation, upgrading ore, and ore will continue to unload ore units, and then enter the sorting system. In unloading mine, due to the reasons such as the height difference and the bridge with the change of digging depth, the impact of changes in perspective, often in the unloading ore leakage phenomenon is difficult to avoid, according to find a 100 liter chain The bucket-type gold mining vessels and the 150-liter chain bucket type gold mining vessels are respectively 5% -8% of the original amount of ore leakage. When the amount of ore ore excavated is large and the amount of ore leaching is more In severe cases, this figure tends to exceed 10%.
