Electricity is an essential energy source for cement production, and it is used in raw material grinding, clinker calcination, and cement grinding. The industry's electricity consumption accounts for about 2.88% of my country's total electricity consumption. Under the background of "Double Carbon Targets", the cost of electricity consumption in the cement industry has risen sharply, and reducing energy consumption has become a rigid indicator for the elimination of outdated cement production capacity. Permanent magnet synchronous motors have become the key to reducing power consumption in the cement industry. Using our permanent magnet synchronous motors for transformation After that, the average power saving rate of previous projects can reach 10-40%.
