FITNESS-FOR-PURPOSE: SHOULD YOU BUY ONE GRINDING MILL FOR THE PRICE OF TWO?

摘要

The early to mid 1980s was a period of miningrnconsolidation, and many senior design engineersrnretired from the mill industry. Similar conditionsrnhave existed in the last few years. This creates arnloss of a tremendous amount of experience. Thisrnpaper is a look back by two senior mill designersrnwho survived the dips in both time periods. From arncontinuous design practice of over 25 years, millrndesigns and fabrication practices are surveyed withrna view of identifying what works, and is necessary,rnand what doesn’t, or is not necessary, in the creationrnof a safe, economic, long-lived grinding mill.
