CLINKER GRINDING IN CEMENT PRODUCTION

In this article, we will consider the composition of clinker and its impact on grinding balls deterioration in milling process. Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed.
