We grind white marble limestone to make a super fine white slurry. Most of the contaminants that can discolor the slurry are slightly magnetic. What option do we have to try and separate the magnetic contaminates?
You can buy a magnetic plate and suspend it above the white slurry and it should pick up all the metal. We have a super powerful one in stock Plate Magnet Neodymium 400mm x400mm x120mm.
Alternatively you could buy some magnetic separator bars and have the slurry pour over it and it would collect contaminants.
They have M6 threads on the end and can be joined to form a grate.
