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
Even if the ball mill is dried, only the material with moisture content of 3%-4% can be dried. . Therefore, vertical mills are used for the production of materials with large moisture content, which not only saves economic costs, but also saves time costs. 6, the way of discharging The vertical mill discharge material is forced to avoid over

1. The energy consumption rate of the ball mill is relatively low. At present, there is a tendency to be replaced by vertical mills, roller presses, etc., but the ball mill has a “granular shape that is approximately spherical, which is conducive to raw material calcination and cement hydration hardening”.
Turnkey mills for the mining sector for throughputs up to 1,500 tph and finenesses from a feed size of 300 mm to a product size of 80% < 40 µm; Vertical roller mills. CEMTEC's completely new and innovative vertical roller mill constitutes one more step toward more efficient grinding of soft and medium-hard products.
ball mills, have led to the development of a new generation of Cement Grinding Additives. These products have been specifically designed for the use in vertical mills, optimising both mill output and cement quality. Besides high levels of energy efficiency, vertical mills have the following advantages:
Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed
