re Re: Pre-grinder
The pre gorund material is almost 90 % through 1mm .It is very fine .To regualte the feed to weigh feeder we needto install prefeeder and provide wider width belt to avoid spillage and space for settling the dusty clinker to ensure weighing accurracy .The problem can be better addressed to weigh feeder suppliers for accurate solution.
