Abstract: A deflector (30) for a pulverizing bowl mill (10) includes a plurality of first upper plates (72) and a plurality of second upper plates (74) arranged with the first upper plates (72) to form the deflector (30) positionable on an inner surface of a substantially closed separator body (12) of the pulverizing bowl mill (10). Each of the second upper plates (74) comprises a skirted lower edge (75) that extends beyond a lower edge of each of the first upper plates (72). Each of the second upper plates (74) is also positionable in the pulverizing bowl mill (10) upstream of a journal (24) supporting a grinding roller (22) to deflect a flow of air (32) around the journal (24).
