Obviously by looking at these figures the vibrating screen is underperforming. Is anyone able to provide an indication or reference for the required values for frequency, amplitude, screen deck acceleration. I have ordered the AEM Vibrating Screen handbook but being from New Zealand it is taking 20 days to get here.

The first rule is vibrating screen manufacturers recommend generally DO NOT WELD. But, alas.....sideplates crack and go bad during mid season operations and welding sometimes is just plain necessary. Most people.....just FILET weld the whole crack only to come back the next day and find it cracked beside the weld again.
