SECTION XIII. VIBRATING SCREEN ASSEMBLY
The vibrating screen is driven by an electric motor. Power is transmitted to the vibrating screen, from the electric
motor, by two V-belts. The vibrator screens determine the grades of aggregate desired. When the vibrator screens are
changed, the crusher roll clearance must be adjusted (fig. 50) to the size of the largest screen opening used.
Vibrating Screen Drive Belts Adjustment
