force on the vibrating screen comes from the rota tion of the eccentric blocks inside the exciter. According to the vibration parameters of the used exciter, the exciting force can be calculated, and

Schenck Process directional force exciters series DF are used to drive vibrating conveyors or vibrat-ing screens with exciting forces from 43 up to 603 kN per exciter. Contrary to unbalance motors, directional force exciters have the advantage of well defined force flows and defined mechanical loads in the vibrating machine.

Vibrating motion for a screen is provided by means of out-of-balance motors or geared exciters. Enduron® vibrating screens use high g-force geared exciters for machines wider than 1.8m (6') to provide the vibration motion required. The major part of the exciter drive is the housing, which is a cast metal enclosure and serves as an oil bath.

The flip-flow vibrating screen (FFVS) is a novel multi-body screening equipment that utilizes vibrations to classify bulk materials in the field of screening machinery. The relative amplitude of FFVSs determines the tension and ejection intensity of elastic flip-flow screen panels, which is a critical operating parameter affecting the …
