function of ball mill in cement manufacturing process
Cement Clinker Grinding Aids
The first commercial use of grinding aids in the cement industry came about 40 years ago. These grinding aids are usually organic liquids, added in amounts usually not exceeding 0.25Z by weight. They are used to increase the product fineness at a given production rate or to increase the production rate at a given product sire.

Clinker grinding technology in cement manufacturing
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 burning the benefits ...

This conclusion was drawn from a series of tests in which Portland cement was ground either conventionally in a ball mill or in high-pressure grinding rolls. The water demand of the ball milled cement was 27 per cent and of the high-pressure ground cement was 32.5 per cent, at the same specific surface area (350 m 2 /kg).
