In tower mills, there is no cascading action as in standard grinding mills. Stirred mills are also common for mixing quicklime (CaO) into a lime slurry. There are several advantages to the tower mill: low noise, efficient energy usage, and low operating costs. Table top hammer mill Vertical shaft impactor mill (VSI mill)

The energy efficiency is important in all kinds of activities, and in industrial processes it's a very important factor both economically and environmentally. In the grinding processes, the energy efficiency is determined as much by the current that needs the motor of the mill as of the time that delays the grinding process, these two variables remain determined by the speed on which it feeds ...

Maximum efficiency is usually near 75% of rated load. Thus, a 10horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at hp. A motor 's efficiency tends to decrease dramatically below about 50% load. However, the range of good efficiency varies with individual motors and tends to
