<p>A stationary material mixing apparatus in the shape of a cylindrical conduit (31) being open at both ends. The conduit (31) houses a plurality of mixing elements (33, 34, 35, 36) which are characterized as having no edges perpendicular to the longitudinal axis (37) and which are sized and positioned within the conduit (31) such that at any plane passing perpendicularly to the longitudinal axis (37), at least 75 % of the circumference of the conduit (31) is free of any mixing element.</p> |
