Beater mill for crushing and/or grinding mineral matter comprising automated adjustment means

摘要

The machine has a secured unit moving shock shields (9) from a circular trajectory of swatters. An automated adjusting unit (11) has a hydraulic jack (13) on a lateral side of a frame. The jack has a jack rod (13a) and a cylinder (13b) respectively connected to a crossbeam (14) and to a work column (20) that slides with respect to a tilting rear part (3) of the frame. The adjusting unit has an electronic or electrical control unit to control the displacement of the rod to define various lengths of the jack, where each length corresponds to a gap determined between the shields and swatters.
