螺旋分离器是一种重力选鑛设备,根据苏联专家建议,于1956年1～6月在选别砂鑛方面进行了半工业性试验,现在正在进行工业性试验。半工业性试验的结果表明,螺旋分离器在用于砂鑛粗选方面,具有特别的优越性,经济技术指标远远地超过了现用的选鑛设备(溜槽)。
Spiral separator is a kind of gravity mineral processing equipment. According to Soviet expert’s suggestion, semi-industrial test was carried out in January-June 1956 in sorting sand ore. Now, industrial test is underway. The results of the semi-industrial tests show that the spiral separator has particular advantages for the rough selection of sand ore, and the economic and technical indicators far surpass the existing mineral processing equipment (chute).
