The hammer mill grinding circuit ran near the total rated power of 42 kW for the wood chip grinding. The SEC was kWh/OD kg wood. The net SEC, calculated by subtracting the energy input of idle run from the SEC, was kWh/OD kg, or 74% of the SEC. The ratio of the net SEC and SEC is an important parameter for evaluating grinding ...
