2.2  Separator, magnetic drum and hopper 

 
The  abrasive  separator  is  mounted  to  the  end  of  the  recovery  duct.  It  separates  the  abrasive  from 
contaminants  and  feeds  the  cleaned  abrasive  onto  the  magnetic  drum(2).  This  magnetic  drum  functions  as  a 
second separator for bigger particles and feeds the cleaned abrasive back to the abrasive storage hopper(7). 
 
Two wire meshes are fitted to prevent any coarse contaminants from getting into the blast wheel. In order to 
clean the wire mesh drawers, the drawers can be removed from the sides(8).
