Cement Kilns: Size Reduction and Grinding

As has been discussed, mills that rely upon sieves for their fineness control may be suitable for rawmix or coal grinding, but for cement, particles leave the mill as soon as they are just fine enough to pass the sieve, and the ultra-fines needed for cement strength are not produced in quantity. For this reason, such ball mills were only used as a pre-grind stage, followed by - for example ...

16/06/2016  That would make the most sense.Grinding down exposed aggregate just seems like opening a can of worms. Grind too little and you now expose more sharp edges, grind too much and you have a slick surface (much like poured concrete flooring) that is a huge headache in wet areas. You can provide flipflops for every visitor for the next decade or so at a lot less cost and headache.
