Abstract
A camming member is used to adjust two beater grates. The camming member has two circular camming discs. The first camming disc engages an oval aperture on the first beater grate. The second camming disc engages a U-shaped slot on the second beater grate. An intermediate transition grate is located between the two grates and is bolted to the camming member. The transition grate has a radial aggressive profile and a tangential less aggressive profile. By rotating the camming member the beater grates are moved up and down and the profile of the transition grate is changed.
