NONFERROUS INDUSTRY

The sintering method and the Bayer process are currently the main methods for industrial production of alumina.

Most of the alumina produced is produced by Bayer process.

The Bayer-sintering hybrid method was first created, which greatly improved the total recovery of alumina.

With the continuous improvement of production technology, some new production methods such as lime Bayer method and beneficiation Bayer method are continuously applied to production.

The integrated process control system is a distributed control system.

The system consists of eight process control subsystems (workshop) for raw material grinding, lime digestion, dissolution, sedimentation, seed filtration, evaporation, product filtration, and roasting.

Each workshop has an engineering station EWS and 2-3 operator stations OPS.

The data collection, real-time monitoring, data processing and other information transmission of the internal process parameters of the workshop are realized by the EtherNet/IP control network.

The main production operations of the entire alumina plant are completed by these eight subsystems, each controlled by a ControlLogix controller.
