Web5) insufficient inclination of screen surface. For the circular vibrating screen, the most common reason for the poor screening effect is the inadequate inclination of the screen surface, so it is necessary to pad the back support. In practical application, the inclination angle of screen surface is more suitable when it is 20 degrees. WebSep 1, 2012 · This is known as shielding effect or screening effect. Poor shielding therefore means poor screening of nuclear charge. In other words, the nuclear charge is not effectively screened by electrons in question. -s orbitals have the largest screening effect for a given n value since s electrons are closer to the nucleus.
