Apr 4, 2020. The name "ball" or "pebble" refers to the type of grinding media that is introduced into the mill. The media when combined with ores or other subtances accelerate particle size reduction by virtue of their impacting on the particles as the mill rotates. The grinding action is as described in our article about how grinding ...
In this essay, I will explore the history of milling, the processes involved, the impact on our nutrition and the directions that we can choose to go in, if we want to consume healthier, more localized bread. To begin with, a field of wheat is converted into a loaf of bread by breaking the grain open and grinding it in a process called milling ...

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
The control of ballmills is relatively simple in comparison ( addition of balls to maintain power and control of the cyclones and pulp density). Pebblemilling is used on some mines for secondary grinding, to reduce operating costs. However, the availability of pebbles is essential and pebble storage is required.
