Study of a threshing device in the line of primary flax processing
The paper presents the methods and results of the experimental research into determining the degree of flax heads threshing with a device with an elastic working part in the line of primary flax processing of the firm Van Dommele Engineering. As a result of the experiment the mathematical model of flax threshing has been obtained. It's established that the threshing degree Е = 98.81 % can be received when the speed of flax band transporting is 1.41 m/s (v = 1.41 m/s), the space between a working part and concave is 0.01 m (Д = 0.01 m) and the frequency of cylinder rotation is 2.92 s <sup>-1</sup> (n <sub>6</sub> = 2.92 s <sup>-1</sup>).
