FIELD: mining engineering.
SUBSTANCE: device for mechanised rock development has an inclined scraper conveyor 1 with at least one sieving element 3, and a second inclined scraper conveyor 2 with at least one sieving element 4. The upper end of the first conveyor 1 is above the lower end of the second conveyor 2. Wherein, at least the first conveyor is configured to adjust the height of its upper end.
EFFECT: simplification of the design and simultaneous adjustment of crushing capacity by changing the impact force, reduction of ash content.
