As the name suggests, screening buckets are a particular type of excavator and loader attachments, designed to “screen” materials. They are used for screening and separation of materials, both before and after a crushing phase. They feature a number of screening blades – designed in different configurations-, which allow different particle sizes of screened material, depending on the job’s requirements. Simply said, screening buckets are able to separate materials of a particular size or shape, that pass through them, from the rest of the matter.
