When you say "particles" I assume you mean broken particles of ceramic correct?
On your machine you state to have a Sweco screener. What size screens are you using? Do both types use the same screener?
As you know the types of media you are using are close in size
AZB425 .425mm and ASR 110 .300mm. Your Sweco will basically only maintain the size of the media, broken partials need to be removed by using a spiral separator. Do you have one?
