The revolving magnetic grille is a magnetic filter that separates ferromagnetic particles. Its main feature is that it helps the product flow due to its spinning magnetic bars. They therefore help the already purified product towards the exit. The magnetic bars are covered in stainless steel sleeves. By means of a pneumatic system, these sleeves are withdrawn from the separator and the ferrous contaminating particles are released into a reservoir outside the separator, without the need for manual cleaning by the user. There is also a manual cleaning option.
