2015.3.1 MPS mill (roller-race) model. The most significant difference between the MPS and E-mill designs is the grinding mechanism. The MPS mill uses a three roller-race system instead of the 10 ball-race system deployed in the E-mill. The elutriator zone in the MPS mill also appears to be closer to the air classifier entry area.
