Screening machine with acceleration-constant control |
摘要 |
In a screening machine with a three-dimensional oscillating screening movement and a control unit for converting a given vibration level into the required energy supply for the electromagnet, the results of screening analyses are to be reproducible or comparable; to this end it is provided that the control unit (26) is designed for calculating the machine acceleration as a function of the respective determined vibration level and the simultaneously determined frequency value as a control value for the energy supply to the electromagnet and for the setpoint-actual value comparison of the calculated machine acceleration actual value with a given machine acceleration setpoint value and for compensating a determined machine acceleration deviation by adjusting the energy supply to the electromagnet (21) on the basis of the change in the vibration level calculated as a function of the given frequency.
