mills gained in importance. However, it was not until the introduction of the diesel engine in the early twentieth century that high- speed mills were seen in more significant numbers across the continent. A relatively low-speed, water-cooled diesel engine can, for example, power a hammer mill, producing maize flour of acceptable quality.
Feb 25, 2016 The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and particularly the Edison roll crusher and in these machines ...
