About inertial screens

A. About the simplest vibrations of the frame of an inertial screen. This part of the article discusses the conditions under which it can be considered that the screen oscillates perpendicular to the plane of its sieve. An inertial screen is a sieve inclined at an angle a (from 5 to 40°) to the horizon and supported by several (usually four) strong springs perpendicular to the screen frame (see article). B. On the movement of inelastic rock along a normally oscillating inertial screen. In this article I will limit myself to considering the motion of an inelastic particle: after hitting a screen, the particle will remain on it until its negative acceleration exceeds the acceleration of gravity; from this moment the particle breaks away from it and moves along a parabolic trajectory until a new collision.
