ABSTRACT:
This invention provides a ram for use in a mixer with counter-rotating non-intermeshing rotors on which the central portion of the ram utilizes a apex, either a point or a line produced by a “V” or similar shape, that protrudes a given distance into the mixing chamber and on which the end portions of the ram are either horizontal such that they do not protrude into the mixing chamber at all or are otherwise shaped such that they protrude into the mixing chamber less than the apex of the central portion of the ram.
