External circulation technology for VRM raw meal grinding

    The pressure differential of a traditional vertical roller mill (VRM) system for raw meal grinding is high, with the fan accounting for about 45 per cent of power consumption. Sinoma International Engineering has developed external circulation VRM technology for raw meal grinding, whereby materials are transported by elevator instead of gas flow, leading to reductions in pressure differential and power consumption.
