Clinker size and cement grinding GCP Applied Technologies

For ball mills, it is more efficient to reduce the size of large particles prior to the mill, using physical means such as a hammer crusher, pre-grinder, or a roll press. Fine clinker is less of an issue in a ball mill, since the material simply passes through to the second chamber for fine grinding, although this can reduce the impact of the 1st chamber crushing action somewhat.

Calculate and Select Ball Mill Ball Size for Optimum Grinding

2/8/2013· In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

Cement mill Wikipedia

A cement mill (or finish mill in North American usage) (although this depends upon feed input size mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter). Ball diameter here is in the range 60–80 mm. In a two-chamber mill

Cement grinding Vertical roller mills versus ball mills

today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials. 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
