Cement Plant Grinding Mills Power Consumption. To calculate theoretical horsepower required by a grinding mill to reduce feed material to a certain size from Bond grindability test data, it is necessary to apply the "Bond Third Theory of Comminution.". The first step in this procedure is to calculate from the following formula the work ...
