Development And Reform the Iron Ore Processing Self Grinding Equipment

Many types of iron ore equipment, we often hear some iron ore processing equipment and iron ore crushing equipment. By adopting the combination of flexible transmission system since the mill by a certain division of manufacturing, in twentieth Century 90 time metaphase is applied in Iran iron mine (3 West 9.75 m X4.72 m semi autogenous grinding, each power of 2 x 4000 kW) and Zhang Italy arc of a copper mine F1 Taiwan hit 10.36 (2) gearless drive ring motor. In the self grinding (Ban Zimo) no gear driving machine adopts ring motor is an innovation. Ring motor for low speed synchronous motor, the rotor is fixed in the barrel body on. Its advantages are: 1, large driving power, the gear transmission is difficult to be used to solve the problem of large mill; the short drive chain, the transmission efficiency is high; the convenient using variable frequency speed regulation; the whole area of equipment is reduced. The disadvantage is the high price is around 25% device of gear transmission. In 1989, Sweden BolidenAllis company in the world for the first time made 2 gearless drive semi autogenous grinding, specifications for coffee 9.75 m * 4.57 m, power of 8206 kW for XXX, Chile copper concentrator. To twentieth Century the end of the 90's, the world's nearly 20 self mill (Ban Zimo) machine using this drive mode, mostly large equipment.                                            Related knowledges and articles:/grinding-machine/on-the-construction-of-garbage-sorting.html                                      /news/sand-production-line-in-to-do-protection-work-and-save-the-cost-of-winter!.html
