The ground material is discharged through a discharge hollow shaft. Due to the constant uniform feeding, pressure will causes the material in the cylinder to move from feed end to discharge end. During wet grinding, material is carried away by water flow; during dry grinding, raw material is taken away by the airflow drawn out of cylinder.
