Ball mill
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal I see that several have answered based on dry grinding, i.e. Vertical Roller Mill vs. conventional Ball Mill. If we instead focus on wet grinding, we should differentiate between stirred media grinding, which can be both vertical and horizontal, and tumbling mills with manufactured grinding bodies.Vertimill VS Ball Mill Grinding & Classification Circuits

Vertical roller mills: The new leader in grinding technology
The Loesche VRM has adaptable grinding modules which are already proven to be the way forward in other mining industries, allowing for variant mineral ores to be milled efficiently to the required particle size. The VRM, depending on the roller size, has a high reduction ratio; feed from 80 mm to 140 mm to a product of P80 at 75 µm in one A decided advantage of the vertical roller mill compared to a ball mill is its ability to dry feed materials with high water content, like for instance slag.

A Technical and Economic Comparison of Ball Mill Limestone
A pilot-scale Loesche VRM was used to determine the power required to grind 100 t/h of the same limestone as used at Kusile (work index of 12 kWh/t) with a top size of 19 mm to a 85% and 95% passing 45 µm product. A significant power saving of 39.2% was observed for the dry VRM compared to the wet ball mill (37.7% for the circuit).It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are air-swept ball mills and vertical roller mills. At present, most cement plants use coal as the main fuel in the clinker production process.
