Screening machine for difficult material - with beater strips on oscillating frame with unbalanced mass drive

摘要

A screening machine for the separation of material which is difficult to screen is equipped with several beater strips which knock against the underside of the screen area. These strips are rigid elements and are supported in a rigid oscillating frame which is coupled to a vibration drive with unbalanced masses. This screening machine has a simple design and has an improved efficiency for the separation of materials which are normally difficult to screen. It has the same good effect in all parts of the screen area and can be readily added to all existing screens. Clogging by fines is effectively eliminated.
