Dromone says its screening buckets’ bi-directional rotor system reduces build-up of material and eliminates blockage. The attachments are available with extra interchangeable rotors to cope with varied material. Three models are available to fit excavators from 14 tons to 39 tons – an 11- to 14.3-ton model, 17.6- to 22-ton model and 33- to 38.5-ton model. All consumable parts are designed to be replaced on site, and bucket teeth are compatible with the Cat tip and adapter system.
