How to Maximize Efficiency at Your Cement Plant with
In a ball mill, the grinding process takes place by impact and attrition. On the other hand, a vertical roller mill exposes a bed of material to a pressure high enough to fracture the individual particles in the bed. This process creates a stable and consistent grinding bed between the rollers and the VRM table.

Cement grinding Vertical roller mills versus ball mills
For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.

CEMENT GRINDING SYSTEMS
Finish grinding system. Press equipped with separator and desagglomerator. Cement is ground in roller press only. Rule of Thumb. 1 [kW] absorbed in the press replaces 2 – 2,5 [kW] in the tube mill. If roller press is used as a retrofit for existing systems, capacity increase of. 25 – 50 [%] can be achieved.
Clinker grinding technology in cement manufacturing
By. admin. Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started …

Grinding ball | Magotteaux
Critical Speed and a Grinding Ball. For the ball mill to work properly, it must reach critical speed. This is the speed at which the grinding balls start to spin along the ball mills' interior walls. If the ball mill does not reach critical speed, the grinding balls will stay at the bottom. They won't be able to grind the material properly.
