Some days, certainly in my line of work, you learn something new and interesting about a new industry. On the other hand, sometimes when you investigate a new industry you’re simply overwhelmed and inundated with new, apparently meaningless phrases, words, acronyms, jargon, and lingo simply leaving you confused none-the-wiser. If you consider yourself to be someone firmly based in the former camp, now might be a good opportunity to go and make yourself a cup of tea with a biscuit. For fans of the latter, you’re in for a treat as we delve fearlessly into the subject of grinding media!
