Most vibratory units run dual self synchronized unbalance motors for reliability. All screens are located into position by a manually operated clamping element. These graders are supplied with four post type pillars for floor mounting, it is recommended that if the unit is to be mounted above the nominal pillar / floor height that an additional sub structure & bracing set would be required to isolate the startup and shutdown forces generated to the surrounding area. The operation / function of the multi deck grader is to split the product being feed across it into various size fractions, the volumes and sizes screened are determined by the screen configuration in the grader, various sizes and configurations can be stripped out at different levels and at different volumes.
