 · In order to perform the tests, based on the above-mentioned centrifugal fertilizer spreader, a spreading model with the following technical parameters was developed: dual disc; distance between the discs—105 cm; disc diameter—60 cm; length of the blade—32 cm with non-rotating angle and 36 cm with a 5° rotation, respectively.

 · centrifugal spreaders have been modified to enable even larger operational widths that additionally increase their high productivity and decrease costs [15]. The spreading width can now reach to over 45 m [16]. z y x O Figure 1. A centrifugal fertilizer spreader, having a flat disc with straight radial vanes.

 · The correctness of the developed model was verified by comparing the transversal distribution of the applied amount of fertiliser from the model with the measured one resulting in a root-mean-squared error of 2.08% and a Pearson correlation coefficient of 0.96. Keywords: VR application, centrifugal spreader, on- and off-disc dynamics

 · Approaches to modelling particle flow off centrifugal spreader discs. Centrifugal fertiliser spreaders dominate the market in most agriculturally developed countries; their main advantage is their low price, wide application width and high output. Their main disadvantage is the sensitivity for spread characteristics to change with

 · To facilitate calibration and avoid unnecessary waste of pesticide or fertilizer, this quantity is reduced to a much smaller area. This is done by setting up a ratio or proportion problem and solving for the unknown. 180 Pounds. X Pounds. 43,560 sq. ft. 250 sq. ft. In this case, X equals 1.03 pounds (43,560 X = 180 X 250 therefore X = 1.03).

 · PDF Tools Share Summary The success of centrifugal spreaders (80 % market share in Europe) can be explained by their low price, easy maintenance and a working width exceeding up to 15 times the machine width. The main disadvantage of this machine is the high sensitivity of the spread pattern to flow rate variations.
