You are molding plates of Alumina from powder. The customer continues to complain of the poor performance of the plate during cooling. You decide to reduce the particle size for the next order. You place a test batch of powder having a mean particle size of 250 micro-meters into a ball mill for 8 hours. When you check the new size, you find that it is too fine. The average particle size is now 35 micro-meters. How long should you mill the original powder to achieve a mean particle size of 75 micro-meters?
