Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is regarded as a breakthrough.

Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses (typically in combination with a ball mill), and clinker pre-grinders with ball mills. Ball mills have been the traditional method of comminution in the mineral processing industries and continue to operate with old generation ...

Answer (1 of 2): Concrete floor grinders are about the size of a vacuum cleaner. They use horizontally rotating discs to level, smooth or clean concrete surfaces. Concrete floor grinders are similar to "fine" sandpaper in a range of masonry tools, …

a gear unit in a vertical mounting position with an axial fan and air cooling cover Separators can be retrofitted in existing ball mill circulations or integrated into new grinding systems. The X series industrial gear unit and its wide range of options provide a complete drive package - all from a single source.

The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.

Cement grinding mill is usually used in the clinker grinding process.It is the final stage in cement production which will directly affect the cement product quality, output and benefits. Clinker particles, gypsum, and other materials in cement grinding machine will be ground together into fine powder to match the fineness of the finished product.

There are efficiency factors for dry grinding, open circuit ball milling, mill diameter, oversize feed, grinding finer than 75 microns and too large or too small reduction ratios. For cement application, the dry grinding (EF1), mill diameter (EF3), oversize feed (EF4) and fine product (EF5) factors are relevant.

compared to the ball mill, and 20% compared to a vertical roller mill. It is a compact machine installed in a compact grinding plant. The small quantity of materials present in the milling circuit minimises the duration of the transition periods when changing cement qualities, which avoids the production of out-standard cement.
