Grinding mills are infamous for their extremely low energy efficiency It is generally accepted that the energy required to produce new mineral surfaces is less than 1 of the electricity consumed

Breaking down energy consumption in industrial grinding mills

As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions they give cement plant owners a great opportunity to maximise productivity and minimise operating costs The high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited

Vertical roller mills offer supreme grinding
