The article presents a method of vibrating screen trajectory control based on MR (magnetorheological) dampers applied in a screen suspension. A mathematical description of the dynamic screen model was derived, and parameters of this model were estimated based on experimental data from a semi-industrial vibrating screen. The …Web

Soil-cutting forces are key indicators of root-tuber harvesters and other soil-engaging tools' performance. To improve operational efficiency, minimise soil disturbance, and reduce fuel consumption, the draught and vertical forces involved in root and tuber crop harvesting must be minimised. Two field experiments assessed the harvester's …Web

It didn't take long to discover a few flaws. The nature of material I screen has a lot of rock. These would lodge in the screen. The mechanics of the vibrating deck was not adequate to move these rocks across the screen. Several times a day I had to climb up on the deck with a 3lb. Hammer and pound the rocks through to unclog the screen.Web

The amplitude of most vibrating screens is between 1–10 mm. Therefore, the dynamic behavior at 1–10 mm amplitude and 16 Hz frequency is discussed, in which 16 Hz is the common frequency of normal vibrating screens. Figure 4a shows the bifurcation diagram of different amplitudes at θ = 10°, a = 90°, f = 16 Hz, and f c = 0.5. With ...Web
