To leach the metal, crushed ore must be dumped in relatively thin layers of a height of approx. 5 m to 10 m. A conveying and stacking system, including a movable conveyor belt system, traveling tripper and stacker is used for this. The movable conveyor belt system is formed by a plurality of individual belts, the so-called grasshoppers. Provisions are made in the dumping technology for a high block for the end device in the conveying chain, the stacker with its swingable stacker boom, to always discharge an arc-shaped layer of ore, after which the device moves back by the amount of the next layer to be discharged in an arc-shaped pattern. This process is repeated until the stacker has moved back by the effective length of a grasshopper. Conveying is then stopped, one grasshopper is removed from the conveyor belt system and dumping of the ore is then continued. To enable this technology to be used, the stacker must be provided with a material pickup area, which is as long as a grasshopper. Furthermore, the material pickup must take place laterally from the direction of conveying of the stacker to ensure that the stacker is not hindered during the moving back. A transfer grasshopper is provided for this purpose, which stands in the direction of conveying at an angle of approx. 30° to 60° in relation to the main direction of conveying of the stacker. To enable the individual devices of the system to perform the movement intended for them, they are equipped with individually driven and steerable caterpillar-type chassis.

A movable belt conveyor system for a leach pad for use for sulfidic copper ore, where favorable conditions are to be generated for leaching out the copper by a slight compaction of the ore piled up into a dump for the microbiological leaching technology. The movable belt conveyor system of a length of up to several km is composed of a plurality of smaller belt segments, comprising a tail segment (70), standard segments (711-n) and a head segment (72), as well as a traveling tripper (8). To prevent the loading by these individual components from being excessively compacted by the weight of the device during multiple travel over the dump during the moving process, the belt drives with the driving drum are accommodated in the tail element (70), which is supported on the soil next to the leach pad. In addition, the traveling tripper (8) is designed as an independent unit with the belt drums, additional belt drives and the belt-tensioning means, which unit is autarchically displaceable on a caterpillar-type moving gear (85) of its own. Due to the moving of the belt on the caterpillar-type moving gears of the standard segments (711-n), on the head segment (72) and on the traveling tripper (8) as well as due to the absorption of the weight of the tail segment (70) by the transfer carriage (6), the surface pressure acting locally on the dump is reduced and the compaction of the ore on the dump due to being traveled over by the belt conveyor system remains low. Traveling over with a moving device, which frequently happens with the use of a moving caterpillar, is eliminated.

The object of the invention is an apparatus for storage of wood chips in a curved-top stockpile the apparatus consisting of a central tower which supports a conveyor for loading the chips and a beam-like turning pile composer, and a unloading beam supported on ground level on the lower part of the tower as well as on supporting wheels and furnished with unloading devices for transporting the wood chips towards the center of the apparatus. The central tower is furnished at one side with a tubular ex-central opening, and the tower occupies a central tube for delivering the wood chips either upwards or downwards from the opening, whereby a service and passage space is formed between the mantle of the central tower and the transport tube

A mobile bag filling system for filling bags with fluent matter, such as sand, and comprises a hopper, a flume, and first and second conveyor systems. The hopper receives the fluent matter from a source and an auger within the hopper moves the fluent matter onto the first conveyor system and transfers the fluent matter from the hopper up a ramping section to the flume. The flume directs the fluent matter into at least one holding receptacle, or sandbag. The second conveyor system receives the sandbag after it has received the fluent matter and moves the sandbag sufficiently to one side of the flumes to allow a user to fill another sandbag. The mobile bag filling system may also include a sandbag docking station configured to receive the sandbag after the sandbag has received the fluent matter and disconnected from the flume. The sandbag docking station and the second conveyor system are positioned such that when the sandbag is pushed toward the second conveyor system, the sandbag falls onto the second conveyor system. A string clamp automatically seals the sandbags.

摘要:
A flexible feeder conveyor system for removing material from a stockpile and transporting the removed material to a fixed conveyor. The system includes an underconveyor positioned below an excavator and having a loading hopper attached to its forward end to receive material and transport it beneath the excavator a rearward end of the underconveyor. A string of trailing conveyors is towed behind the underconveyor with the last trailing conveyor having its rearward end attached to a stationary terminal support positioned at the fixed conveyor. The underconveyor, the trailing conveyors, and the terminal support are connected together using transition hoppers. Each transition hopper includes an upper hopper mounted to the raised rearward end of the forward conveyor, and a lower hopper mounted to the forward end of the next rearward conveyor. The forward end of the conveyor is rollingly supported by a pair of caster wheels. The upper and lower hoppers are connected together for rotation through both a horizontal plane and a vertical plane. The horizontal rotation is permitted by constructing the upper hopper with an annular support portion and a housing portion rotatably supported thereabove by an annular bearing. The vertical rotation is permitted by a pair of pivot pins attached to the annular support portion which are loosely received within corresponding upwardly opening slots in a housing portion of the lower hopper to permit the upper hopper to pivot with respect to the lower hopper.

A mobile pipe conveyor system which is capable of bending smoothly and freely both in horizontal and vertical within a certain range to be moved and/or laid in zigzag without dropping transported materials in contrast to the conventional flat-belt conveyor, and a method for reclaiming and leveling grounds utilizing said mobile pipe conveyor system arranged between a swiveling conveyor and a base point inside or outside of a land to be reclaimed, the entire pipe conveyor system together with the swiveling conveyor being pulled by one or more bulldozers and easily moved about the base point without adjusting l/e zigzag movement and/or laying, so that reclaiming and leveling works on a large scale can be completed in a short time.
摘要:
A high angle conveying apparatus including a conveyor belt and a cover belt trained for movement in endless paths of travel. The belts are supported for movement by an array of upwardly directed and downwardly directed troughed idler rolls for movement through a material loading zone whereat the belts are out of operative proximity with each other, through a material lifting zone whereat the belts are in operative proximity to each other whereby material on the conveyor belt will be held in contact therewith by the cover belt, and then through a material discharge zone whereat the belts are moved out of operative proximity with each other for discharging material therefrom. Pressure devices are provided to maintain predetermined belt speeds and pressures.
