【Abstract】 The industrial test and production application of D600mm Type GL\|2 spiral concentrator in Panzhihua titanium mineral processing plant for beneficiating the coarse grain particles (0\^4~0\^1mm) at the roughing stage are described. Results indicate that compared with the originally\|used cast iron spiral concentrator with the diameter of 600mm, this new concentrator is characterized by good beneficiation results, strong adaptability and long lifetime; the operational recovery can be increased by 13%; the production cost is saved and the technical and economic indexes of the Ti mineral processing mill are improved.更多还原
