The MVE-Exe Increased Safety can be utilised in a range of industries as flow aids on hoppers or to increase material discharge, or as drives on machines for sizing, screening, conveying as well as compacting. When the MVE-E is turned on, the eccentric weights rotate, producing a sinusoidal centrifugal force. A rotating force is given by only one MVE installed on a machine, leading in a circular movement of the machine. Two counter-rotating MVE placed in parallel on the same machine create a linear force, resulting in machine linear movement. The application determines whether circular or linear movement is required.
