Maurice Ethier, manager of NORTHGATE’s Kemess mine writes:"The article on the Goodyear conveyor belt used by Albian Sands caught my attention, as did the stated capacity. I think that 7 tons/hour might be a bit lower than the user anticipated. You might want to check the math again. Thanks I’m a regular reader and enjoy the articles!"Well, Mr. Ethier, the math has been checked and figure corrected to read 14,000 tons/hour.
