Abstract
An improved arrangement for feeding material through a material reducing machine. An inclined wall is positioned strategic to a material reduction unit and a plunger of the machine. A lower beveled edge of the inclined wall is positioned in close proximity to the material reduction unit and above the plunger. The plunger forces material toward the material reduction unit and the inclined wall. Material that is below the lower edge of the wall will be forced into the material reduction unit and material that is above the lower edge will be forced to elevate on the inclined wall thus preventing jamming of the forced feed mechanism of the machine. Controls are provided to control the rate of movement of the plunger in correspondence with the rotational rate of the material reduction unit. The rate at which the plunger moves toward the material reduction unit is decreased when the rotational rate of the material reduction unit decreases.
