Abstract

Наружный элемент (1) для пульпового лифтера (2), предназначенного для мельницы (3) с вращающимся барабаном, содержит первую стенку (4), направленную к разгрузочному концу мельницы, и по меньшей мере одну лопатку (6), выступающую от внутренней поверхности (12) первой стенки (4) во внутреннее пространство барабанной мельницы (3) и имеющую направляющую поверхность (10), расположенную на передней стороне лопатки (6). Наружная кромка (11) направляющей поверхности (10) расположена под углом относительно внутренней поверхности (12) первой стенки (4) таким образом, что величина угла () между внутренней поверхностью (12) первой стенки (4) и наружной кромкой (11) направляющей поверхности (10) составляет меньше 90°.The outer element (1) for the pulp lifter (2) intended for the mill (3) with a rotating drum contains the first wall (4) directed to the discharge end of the mill, and at least one blade (6) protruding from the inner surface ( 12) the first wall (4) into the inner space of the drum mill (3) and having a guide surface (10) located on the front side of the blade (6). The outer edge (11) of the guide surface (10) is located at an angle relative to the inner surface (12) of the first wall (4) so that the value of the angle () between the inner surface (12) of the first wall (4) and the outer edge (11) of the guide surface (10) is less than 90 °.
