Classifying-liners are the best form of cement mill liners to adapt the grinding charge to the feed material´s granulometry while keeping a smooth material flow going. They are efficient energy wise because of the constant optimum grinding charge. Magotteaux produces several types of these. Xclass® is easy to handle and has increased safety in part because of its reduced weight, which is 35 per cent less than that of more traditional second chamber mill liners. Classoline® is another type of liner. It can be put together in three different ways; vaulted, semi-vaulted or bolted.
