Coal milling Question 1 Page 1 of 1

Re: Coal milling. There are well established guidelines for the safety operation of coal grinding equipment. These fall into two broad categories: (i) explosion prevention, and (ii) explosion protection. For prevention the best solution is to ensure that there is less than 12 per cent oxygen in the atmosphere. You cannot do that when cooler exhaust air is used for coal drying. As a general guideline drying with
