Summary
Worker who extracts aggregates (gravel, sand, clay, etc.) used in concrete and paving materials, and handles crushing, sorting, and transportation.

Aggregate extractors are specialists who extract, process, and transport aggregates necessary for construction materials. They operate equipment such as shovel loaders, dump trucks, and crushers (crushing machines) at quarries or riverbeds, handling tasks from raw material excavation to crushing, screening, and loading. Work includes safety management and quality control, requiring consideration for environmental conservation and local residents. Responsiveness for machine maintenance and troubleshooting is also important.
