The Progressive Industries, Inc. NPR Mill™ is a cross between a stirred media mill and a ball mill. The internal screen seperates the product from the media. The product is discharged and the media is recirculated through-out the mill.

 


The NPR Mill™ is shown in a closed loop setup with an Micro-Sizer® MS-5 where the coarse fraction is sent back to the mill for re-grind.
