Based on the kinematic analyes of 5XF150/180 grain selecting machine, the relationship between amplitude, frequency, angle of throw and other main kinematic parameters of reciprocating separator and relative size, and screening probability was established. There are three ways including passing through the screen surface while the material particles are sliding down or up along the screen, or jumping along the screen for the material particles to pass through the screen surface. Through establishing the mathematic model of the above three ways, the theoretic formula of screening efficiency of5...
