1. Scraper Reclaimers

Scraper Reclaimers

For a fully automatic operation of bulk storages TAKRAF is offering their field-proven scraper reclaimer technology.

TAKRAF scraper reclaimers are leading in terms of high performance and dimensions. Their reliability also in challenging bulk materials, cost effectiveness and long life time are outstanding.

Depending on whether pure buffer storages are demanded or storages for homogenizing and blending of bulk materials, for reclaiming either side or portal scraper reclaimers (i.e. full-portal and semi-portal reclaimers) or bridge-type scraper reclaimers are being used.

Scraper reclaimers are being increasingly employed worldwide in open storages as well as in enclosed or covered bulk storages. They are being used in nearly all industries and for almost all types of bulk materials.

This popularity and increasing application of scraper reclaimers are generally resulting from following machine characteristics:

  • High operational versatility
  • Robustness
  • High efficiency and low operating costs
  • Gentle treatment of bulk material / products
  • Problem-free reclaiming of challenging bulk materials (for example, if sticky or abrasive)
  • Complete emptying of the storage area
  • Transfer of constant and uniform bulk flow to outgoing conveyor
  • Full automatic operation

Our scraper reclaimers have spans up to 70 m and capacities up to 6,000 t/h.

About 400 delivered and successfully commissioned reference machine demonstrate the competence of TAKRAF for designing and supplying field proven scraper reclaimers and highlight as well the company's vast experience in handling different bulk materials such as coal, iron ore, bauxite, zinc ore, kimberlite, potash, phosphate, urea, sulfur, petroleum coke, limestone or slag.

The stackers and scraper reclaimers are supplied for longitudinal and for circular storages.

We offer and supply scraper reclaimers globally. To meet specific market demands from different countries and industries the company has established two centers of competence for their worldwide operations. One is in Germany (located in Gelsenkirchen) and the other one in India (located in Chennai). Both centers together reflect our competence in designing and building scraper reclaimers. An experienced team of engineers is committed to advise you regarding the layout of storage areas and in the application and design of stockyard machines.

    Outstanding span and high capacity of portal reclaimers

    The coal storage is equipped with one stacker and two portal reclaimers serving a railcar loading station. The whole project has been delivered turnkey including installation.

    In general portal scraper reclaimers are mainly used in buffer storages but can also achieve in combination with proper stacking methods certain blending and homogenizing results.

    For high reclaiming capacities of up to 6,000 t/h TAKRAF portal reclaimers are equipped with twin booms evenly distributing the bulk material flow onto two booms.

    For reclaimers with application in covered storages the scraper boom is being divided into a main and an auxiliary boom to cater for the limitation in height set by the building structure. Main and auxiliary boom are always firmly connected with each other in order to guarantee during entire operation and under all conditions a continuous and smooth flow of bulk materials from auxiliary to main boom.
