Large alites means over-burnt clinker thus it's harder to grind. Clinker with a lot of pores are easier to crush. Some (not all) plants can monitor their grindability by watching the clinker literweights. As it rises, the clinker becomes over-burnt; sometimes balls up into bigger pieces; and sometimes it gets very dense (no pores).
