The app collects various indicators from a number of cement production lines during the production process, such as: power consumption of crushing process , power consumption of raw material process, power consumption of coal preparation processes, etc. Users can enter their own production line data, and compare the data with the corresponding indicators from other production lines. Users can not only understand the level of their production line efficiency in the industry, but also know which aspects of the production line should be improved. Therefore, users can carry out targeted operations and management to improve cement production efficiency.
