Drives in steel and rolling mills are exposed to extremely hard demands. Glowing steel, alternating operational modes and overloads spell out a high level of electrical and mechanical strain that calls for very sturdy designs. As a traditional supplier to heavy industry, VEM has developed over decades into a specialist for rolling mill drives.

Grinding systems in cement production make up approximately 85 to 90 percent of total plant electrical energy consumption. 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.
