Abstract: A pulp lifter has a leading edge and a trailing edge with respect to rotation of a rotary grinding mill, and includes a first wall bounding an interior space and a second wall dividing the interior space into first and second regions. The first wall includes an inner edge wall section and a radially outer wall section. The second wall includes a guide that extends substantially from the radially outer wall section to a trailing edge of the inner edge wall section. The guide is configured such that the second end of the guide does not extend to a radially inner edge of the pulp lifter. The first and second walls form at least one inlet opening at the leading edge providing access to the second section and an outlet opening for discharge of slurry from the second section at the radially inner edge and the trailing edge.
Abstract: A pulp lifter and a pulp lifter assembly are described for a rotary grinding mill. The pulp lifter has a leading edge and a trailing edge with respect to rotation of the mill, and includes a first wall bounding an interior space and a second wall dividing the interior space into first and second regions. The first wall includes a leading edge wall formed with at least one inlet opening providing access to the second section, an inner edge wall, and a radially outer wall. The second wall includes a guide that extends substantially from the radially outer wall to a trailing edge of the inner edge wall. The first and second walls form an outlet opening for discharge of slurry from the second section at a radially inner edge. The first section of the interior space is at least partially open at the trailing edge of the pulp lifter.
