5. Abstract The Ball mill is one of the most important equipment in the world of chemical engineering. It is used in grinding materials like ores, chemicals, etc. The types of ball mills: batch ball mill and continuous ball mill with different grinding media and different design depend on the nature of the input material and the nature of the output which I need.
Vertimill® has 50% less footprint than a ball mill. Lower operating cost Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 10 microns. This provides up to a 40% higher energy efficiency.
