Determining the relative velocity of the particles of the layer of bulk material inside the cylinder in the elastic separator
Incoming article date: 15.04.2015Efficient operation of separators bulk materials is possible when the relative velocity layer on the separating surface which knowledge is necessary to determine the optimal parameters and operating modes. Developed methods of measuring and determining the relative speed of the layer of granular material driving inside the rotating cylinder using a tachometer TCh-10P, which increased the size of the tip (roller), diameter with 31.4 mm to 62.8 mm, width 4 mm to 30 mm, and changed the material of the cushion rubber foam. This allowed tachometer TCh-10P to measure the speed of the layer, and to improve the measurement accuracy by reducing the moment of rolling friction and sliding the cushion layer. The relative error of the measurements during the experiments did not exceed 5% and is confirmed by the results of experimental studies of elastic separator. The technique may also find application in the determination of the velocities of the layer in inclined conveyors.
