Hetra-GSS Gmbh offers suction dredgers used in the mining industry and sand extraction. Their main task is to efficiently extract and convey materials such as sand, silt or sediments from the bottom of water bodies or mining sites. The dredgers suck the material through suction pipes and then transport it through conveyor systems for further processing or use. These versatile machines enable effective handling of large quantities of bulk material and help optimize mining and quarrying processes.
