Abstract: A method for filling a terrain using bulk material, preferably excavating material from an ore mine.

Abstract: An angle pipe conveyor comprises a conveyor belt or roller belt. The conveyor belt includes a first conveyor belt section and a second conveyor belt section to define a cylinder structure having an overlap thickness based on plural sections of the roller belt with an overlap structure having an oval- shaped cross section. Support elements support the conveyor belt as rollers located on the support elements guide the cylinder structure.

Abstract: A multiple roll crusher is provided for crushing of mineral material, more particularly of coal or oil sand. The multiple roll crusher includes at least three crusher rolls (1, 2, 5 1?, 2?), the rotation axes (R) of which lie in parallel to each other and horizontal or roughly horizontal. All directly neighboring crusher rolls (1, 2, 1?, 2?) have opposite directions of rotation. A connecting line (V) of the rotation axes (R) has at least one kink.

Abstract: A mobile crusher unit is provided having a supporting framework (12) which is includes at least a crusher unit (13), a feed conveyor (11), and a dumping conveyor unit (14), and which can be relocated by means of a crawler undercarriage. To minimize construction height and weight the supporting framework and the traveling gear are configured as one unit, with parts of the supporting framework (12) serving as parts of the traveling gear, and with the crawlers (16) of the crawler vehicle protruding into recesses of the supporting framework.

Abstract: A twin-rotor impact bar crusher is provided for comminuting preferably limestone, marl, clay or similar materials. The impact bar crusher includes two rotors arranged horizontally parallel to one another and impact bars which are rigidly fastened to the circumference of the rotors in a uniformly distributed manner. The impact bars preferably extend over the entire length of the rotors. The two rotors are arranged next to one another at the same height and rotate inwards in opposition to one another.

Abstract: A travel support device for a conveyor bridge 4 having a swivel joint 12, a two-axis tilting joint 10 and a roller table 8. A portion of the tilting joint 10 is mounted to the swivel joint 12 and another portion of the tilting joint 10 is mounted to the roller table 8 such that the tilting joint 10 rotates about a defined longitudinal axis 30 and an axis 32 transverse of the longitudinal axis 30.

Abstract: A portal-type scraper reclaimer having a support structure 10 and a boom 16. The support structure 10 includes end support members 12. The boom 16 has a main portion 17 and an end portion 15. The end portion 15 is bent relative to the main portion 17. The boom 16 is connected to the end support member 12 at a pivot 26 so that the boom moves relative to the end support member 12. A pair of support sprockets 20 and a pair of drive sprockets 18 are connected to the end support member 12. A boom sprocket 22 is fixed to the boom 16. A scraper chain conveyor 24 extends along the boom 16. The described pairs of sprockets 18, 20, 22 guide the scraper chain conveyor 24.

Abstract: A crushing device is configured as a mobile or semi-mobile unit (1), in particular for use in open cast mining and in the recycling industry, with a feeding container (Z), a feeding conveyor means (3) connected downstream of this for a crusher unit (7), a discharge conveyor (8) serving to transport the crushed product therefrom and a support structure (4), on which the previously named components are held. In order to improve the feasibility of the crushing device, only a single discharge conveyor unit (8) is provided as a discharge conveyor device for both the drawing off and the discharge process. The conveyor unit (8) is constructed to slew as a subassembly in the horizontal and vertical direction relative to the support structure (4).
