They tuber crushers are driven by two vibration motors. The sand lumps are crushed by rubbing against each other. The sand is discharged from the trough onto the sand conveyor floor below via easily replaceable perforated chilled cast iron plates. The pneumatically operated discharge flap is used for the automatic discharge of foreign matter.
Unbalanced Motors are three-phase asynchronous motors with centrifugal weights at the shaft ends. The unbalance can be modified at standstill, allowing the amplitude to be adjusted. The stable and rigid motor shaft and durable roller bearings enable reliable continuous operation, even under difficult conditions. Available with different numbers of poles, the optimum motor speed and therefore the vibration frequency can be ideally selected. Special versions are available for
higher mains voltages, deviating frequencies, explosion-proof or UL/CSA-certified models.
