On what basis is selection of bowl mill is not done?(a) Total moisture

1.	On what basis is selection of bowl mill is not done?(a) Total moisture content of coal(b) Volatile matter(c) Ash producing capacity(d) GrindabilityThis question was addressed to me during an interview.My question is taken from Pulverised Mills topic in section Steam Power Plant of Energy Engineering
Answer» Correct choice is (c) Ash producing capacity Explanation: The selection of bowl mill is done on the basis of TOTAL MOISTURE content of COAL, sulfur and mineral content (used to determine pyrite removal sizing requirement), GRINDABILITY(used to select mill size), volatile matter (used to determine the REQUIRED coal fineness).
