Roller entry guide relating to a rod mill

摘要

A roller entry guide to guide material along a longitudinal axis has a body and a pair of generally parallel roller assemblies pivotally mounted on the body for rotation about an axis normal to the longitudinal axis. Each of the roller assemblies is located on an opposite side of the longitudinal axis to define a passageway for material moving along the axis and includes at least one roller rotatably attached thereto. The guide also includes a wedge that acts between the roller assemblies and the body. The wedge has a pair of legs disposed at either side of the body. These legs have tapered portions at the ends thereof which are operable on respective roller assemblies. An adjustment assembly is operable on the wedge to position the wedge to induce rotation of the roller assemblies about a vertical axis, and cause the rollers to be moved simultaneously and to equal distances towards or away from the longitudinal axis.
