Bucket reclaimer "Cascade"
Reclaimer is equipped with material reverse backfill function from side face top layer to stockpile rear part. Reclaimer takes material from a stockpile “quality” level after production of given material volume and then transports it on factory stockyard conveyor.
Stockpile special preparation is carried out using a stacker or a stacker of gantry or bridge type, which performs layer-by-layer stacking of various ores and additives necessary to obtain alloys with the specified characteristics.
- Bucket reclaimer consists of a truss span structure mounted on supports with a running gear, as well as a bucket elevator with a boom and a chain bucket conveyor mounted on it. The boom can be stationary or swinging one, depending on the type of stacker used at the stockyard.
- Three belt conveyors: basic, mobile and reverse are included in the reclaimer’s design. The Basic conveyor is used for the material transportation to a factory stockyard conveyor at the main process implementation. The Mobile conveyor is used for the possibility of adjusting the position of the discharge telescopic tube when feeding a "low-quality" layer of material back to the stockpile. The Reverse conveyor works as a gate in which the material is transported either to the main conveyor, or to the moving and feeding material conveyor, or to the main or semi-moving conveyor.
- Chain bucket conveyor consists of two chain branches with buckets fixed on them, and also of drive, bypass and tension sprockets, and a drive station. Buckets’ cutting edges (knives) are produced of hardwearing steel.
- To ensure high environmental performance when collecting material, the reclaimer is equipped with aspiration systems in the places where the material is poured and a water mist dust suppression system, the nozzles of which are located along the boom, on both sides, as well as in the lower part of the discharge telescopic tube.
- Reclaimer is also equipped with pneumatic cleaning system of units and the compressor station.
- By means of a system of hose and cable reels water and power supply to the mobile elements of the reclaimer is carried out.
- For the lubrication of bearing assemblies, the reclaimer is equipped with automatic centralized lubrication systems.
- To prevent outsider metal objects from entering the factory stockyard conveyor, a metal detector is installed on the reclaimer.
- By means of special scales, it is possible to measure the production capacity of the material being reloaded.
- The integrated control system provides various modes of automation of the reclaimer’s operation, the integration into the automated control system of technological process of the Customer's enterprise is realized.
- The reclaimer is equipped with a video surveillance system (CCTV) and a remote monitoring system.
Bucket reclaimer "Cascade" is designed in accordance with the requirements of European norms and standards, including environmental standards for noise and dust.
