 · A lack of abrasion grinding will generally lead to a high circulating load of slurry and is symptomatic of a lack of sufficient charge density to effect grinding. In turn, this can be due to excessive lift in the charge liner and speed issues - or a dry charge caused by excessive slurry dilution and drainage through the grates.
