our raw mill is ball mill having capacity of 280tph. but last 10 days our mill is not pperforming well. problem in our mill is the mill is geting jam and relasing, so the return flow is not constant it is vary from 150tph to 290 tph. mill sounnd level is also varying correspondingly. we checked our seperator and all fan damper there is no variation in that and fan power also not having much variation. we suspect first chamber grinding media is less and we put grinding media too. still the problem is existing and the residue is not maintaing. can i get some suggesstion
