目前钨重选厂细泥计量方法有电磁流量计、矿浆计量器、溜槽缩分计量器及直接接取称量等方法。这些方法中,电磁流量计比较先进,但经常受雷电、矿石性质、杂物堵塞或维修不及时等影响,在现场条件下,其误差难于达到说明书上的精度,有时甚至不能使用。笔者调查:江西曾有三个钨选厂使 At present, the tungsten re-election plant fine mud metering methods are electromagnetic flowmeter, slurry meter, chute shrinkage gauge and direct access to weighing and other methods. Of these methods, the electromagnetic flowmeter is more advanced, but often affected by thunder and lightning, ore properties, clogging or maintenance is not timely and other effects in the field conditions, the error is difficult to achieve the accuracy of the instructions, and sometimes can not even use. The author survey: Jiangxi had three tungsten processing plant
