详细介绍了中信重工机械股份有限公司为德兴铜矿设计制造的φ10.37m×5.19m半自磨机和φ7.32m×10.68m球磨机的低压电气控制系统,包括控制系统的组成、配置及主要控制功能等。首次采用了超大功率双电动机驱动方式,实现全液体较厚油膜润滑,功耗大幅降低。该系统已在使用单位稳定运行两年,达到并超过了设计能力,满足了工艺要求。
The paper introduces in detail the low-voltage electrical control system of φ10.37m × 5.19m semi-self-mill and φ7.32m × 10.68m ball mill designed and manufactured by Dexin Copper Mine by CITIC Heavy Industry Machinery Co., Ltd., including the composition, configuration and main parts of the control system Control function and so on. The first ultra-high-power dual-motor drive, the whole liquid thick oil film lubrication, power consumption significantly reduced. The system has been in stable operation of the use of units for two years, to meet and exceed the design capabilities to meet the technical requirements.
