These reclaimers are more suited to the blending of material with medium to high flow rates.
Design features of bridge-type bucket-wheel reclaimers
For higher flow rates and/or larger particle sizes, we strongly suggest a machine configuration in which the bridge is mounted through the bucket wheel. In this manner, power transmission between the bucket-wheel trolley and bridge is enhanced which has a positive effect on machine life.
Configurations include the number of mounted bucket-wheel trolleys and their arrangement. Two carriages can increase material recovery and homogenization and can also be mechanically linked for a common drive system. However, we prefer to install each carriage with its own individual drive. In such instances, our proprietary TAKRAF Speed Controller improves the efficiency of the interaction between the carriages.
Machines can be designed for one or two directional reclaiming and all our machines are fully automated.
Drum reclaimers (barrel reclaimers)
These are ideal for homogenizing and blending bulk material for sophisticated downstream processes, especially for iron ore and/or coal processing. Our machines can be designed for one or two working directions.
The drum reclaimer achieves excellent mixing and blending through:
- Continuous flow and trickling of material on the escarpment across the entire stockpile width
- Simultaneous reclaiming of thin layers of material over the entire stockpile cross-section
- Overlapping discharge of material onto the cross-belt conveyor
Design features of drum reclaimers
All TAKRAF machines are designed to our client's requirements and incorporate various solutions according to the specific application.
Several buckets can be arranged in parallel rows with these symmetrical buckets swiveling automatically in the pre-selected working direction. These buckets continuously remove thin material layers from the stockpile cross-section as they rotate and discharge onto a belt conveyor within the drum. The machine is equipped with rakes. These rakes are equipped with prongs or scraper rods, depending on the particle size of material to be reclaimed, and create a continuous flow of material over the entire width of the pile escarpment directly into the reclaiming buckets.
High-strength, hardened materials ensure a long service life, even when handling abrasive materials. For extremely low temperatures, rakes can have hardened tines to break frozen surfaces.
As a benefit to our clients, TAKRAF provides complete in-house design services, starting from stockyard layout to stockyard automation and the equipment for the stockyard.
These services include:
- Rock testing
- System sizing and arrangement
- Automatic operation
