Washing Drums are commonly used for the vigorous washing of rocks, gravels and minerals with coarse grain-size distribution, as well as for the preparation, homogenization and scrubbing of materials which will be later treated by wet process. Log Washers are indicated to liberate hard plastic clay, friable soil and soft materials from coarse aggregates and rocks not exceeding 75/100 mm size. Main feature of this equipment is the twin shaft fitted with replaceable abrasion resistant paddles to encounter the toughest duty. This type of equipment is indicated for the fine classification of materials by means of inclined vibration screens and high frequency screens available in various models.
