螺旋选矿机在工业上的应用,在国外也只有二、三十年的历史,而我国还是一项新颖的技术。它最大的特点是设备本身不需要任何动力,同时由于结构简单,造价低廉,占地面积少,因而建厂快,投资少,操作容易,劳动生产率高,应用范围广泛。它对于高品位和低品位的砂锡矿均获得良好的技术经济指标。由于具有上述的优点,因此在选矿工业中大力推广应用螺旋选矿机是符合党总路线多快好省的方针。
Spiral concentrator in industrial applications, only two or three decades abroad, while our country is still a novel technology. Its biggest feature is the device itself does not require any power, at the same time due to simple structure, low cost, small footprint, and thus build fast, less investment, easy operation, high labor productivity, wide range of applications. It is a good technical and economic indicators for high grade and low grade sand tin mine. Because of the advantages mentioned above, it is a policy that the spiral concentrator should be widely promoted and applied in the beneficiation industry in line with the principle of making the party’s general line faster and better.
