Sustainability of Grinding Tools

Abstract

Sustainability of grinding tools can only be discussed with a deep understanding of all relevant system components. This chapter summarizes the analyses and conclusions from the preceding chapters into a holistic description model.

In 1822, grinders did not become old:.

About thirty years ago, the steam engine was first adapted to the purposes of grinding; and then a very important era arrived in the annals of the grinder. He now worked in a small low room, where there were ten or twelve stones; the doors and windows were kept almost constantly shut; a great quantity of dust was necessarily evolved from so many stones, and there was scarcely any circulation of air to carry it away. […] If, then, the grinders’ asthma were a disease of not unfrequent occurrence before, it is probable that its frequency would have been much increased now. Such, indeed, was the fact; and it is at the present time become so general, that out of twenty-five hundred grinders, there are not thirty-five who have arrived at the age of fifty years. [KNIG22].
