我厂是一个日处理能力50吨的黄金小选厂。以φ900×1800毫米球磨机和φ450毫米螺旋分极机构成闭路磨矿作业。几年来,由于螺旋分级的给矿是由砂泵直接输送,造成分级机工作不正常,分级效率低。针对这种情况,厂三结合小组,以φ350毫米水力旋流器代替螺旋分级机,获得成功。 Our factory is a small processing plant of gold processing capacity of 50 tons. The φ900 × 1800 mm ball mill and φ450 mm spiral pole machine form a closed-circuit grinding operation. In recent years, due to the spiral grading to the mine is transported directly by the sand pump, resulting in grader work is not normal, the classification efficiency is low. In response to this situation, the factory three combined with the team, to φ350 mm hydrocyclone instead of spiral classifier, to be successful.
