Ore, Rock & Aggregate Screening (Complete Guide)

Jun 20, 2016 · In practice, the stroke used in a horizontal screen is 7 – 20 mm. A small stroke can be used when screening with a small hole size. Because of mixing and separation, a large stroke is recommended. Stroke is defined by the swinging mass and the flywheel moment of the vibration unit. Rotation speed has no visible effect on the stroke.
