Technology 3. One mass shaker conveyor systems: Installation instructions Rocker mounting angle β: According to the relevant processing function of the shaker conveyor, the rocker arms are positioned at mounting angles between 10° to 30° in relation to the perpendicular line. (The ideal combination of fast conveying speed with high material throw is given by a rocker inclination angle of 30°.) The power input position of the drive-rod from the eccentric drive should stay at right angles to the rocker arms, this orthogonal positioning offers a harmonic course of the drive system.

Technology 5. Maximum rocker load G, revolutions ns and angle of oscillation α Size (e.g. AU 15) max. load capacity per rocker [N] The angle of oscillation α of each oscillating component (rockers accumulators and drive head) has to be settled within the permissible range (ns and α). Calculation oscillation angle for rockers Eccentric radius R [mm] Center distance A [mm] Oscillation angle α ± [°] Please contact ROSTA for the permissible load indications by higher accelerations and for rocker elements offering higher load capacities. Usually are the revolutions ns between 300 to 600 min -1 and...
