In an open-pit mine slope, rock mass has multiple joint structures and blasting operations have an obvious influence on its stability. Therefore, accurately predicting the blastingvibrationis necessary to ensure slope stability. In this study, the blastingvibrationsignals monitored at a blasting site with different rock masses were used to investigate the attenuation characteristics of ...

A Vibratory Sifter is a Screen Separator is a screening machine that vibrates around its centre of gravity. Vibrating of screens is done by eccentric masses on the lower and upper ends of the motion-generating piece. Rotating the top mass in a circular motion, creates a horizontal planevibration,causingmaterial to travel across the stainless steel sieve and over to the periphery of the ...
