In a roller press, clinker material is subjected to extreme pressure between opposing rollers for a short time
As vertical roller mills are to 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. In standard cement mfr. by co-grinding cement clinker and a sulphate source the novelty is that the cement clinker and the sulphate source are crushed in a high pressure roller press and the finished cement is sepd. from the pressed and deagglomerated material by a sieve the oversize material being returned to the roller press and heat being

vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production when they want to design new grinding plants or a new integrated finish grinding of portland cement, slag and blended cements. the mill consistently uses five to ten percent less power than other cement vertical roller mills, and in comparison with traditional ball mill operations, the energy requirements for the OK cement mill is percent lower for cement grinding and percent lower for slag.
