May 11, 2015· industry has increased the demand of cement. Increase of the cement utilization demands for higher production efficiency and ultimately low production cost. The efficiency of the cement production depends greatly upon the efficiency of a grinding mill which consumes 60-70% of the total electricity consumption of the cement plant[12].

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.

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

They are cement pre-grinding technology, equipment modification technology, powder separator transformation technology, new abrasive body and grinding aid.
