The choice of a costructive and technological scheme of a separation device and the parameters of its sieves

As a result of theoretical research of separation of flax heap with slugged oscillating sieves equations of motion of flat slugged oscillating sieves and boundary conditions of their operation are received. When using slugged oscillating sieves for driving the heap up on the surface of a sieve the kinematic parameter of a sieve boot is 41–76% lower than one of the existing sieve boots, for driving the heap downwards it is 21–23% lower, for separating from the surface of a sieve it is 54–85% lower that allows to reduce the power to be spent on purifying the seeds by 12.7–27.2%.
