Keestrack introduces the new green electric alternative for their Explorer range of classifiers named ECO-drive. The Explorer 1500 and 1800 (Fig.), both available as 3 and 4 split classifiers, are now also available in the ECO-drive version. The electrical driven machine can run autonomously by the diesel engine which generates the electric power. However the electricity can also be supplied by the electricity network or from an electrical plug on the crusher. The screening results are the same as the standard diesel/hydraulic driven version however the maintenance costs of the ECO-drive diesel engine is much lower as this machine also runs on ‘external’ electricity coming from the power network or generated from the engine of a crusher placed before the classifier. This saves energy, money and reduces emissions.
