Reclaimers

Sandvik reclaimers are designed to reclaim bulk materials from stockpiles at mines, ports, steel plants, power stations, etc. in a quick, efficient and orderly way. They are available in several main types, including bucket wheel, scraper and drum-type reclaimers, and in many configurations and sizes, with capacities from 500 to 20 000 tonnes per hour and more. The choice of design depends on factors such as the size and shape of the stockpile, the type of material to be reclaimed, the required reclaiming rate and the need for blending or homogenization.

Boom-type bucket wheel reclaimers PR100-P200 series

Sandvik boom-type bucket wheel reclaimers PR100 (pylon-type) and PR200 (rocker-type) are designed to reclaim large volumes of bulk material from stockpiles at mines, ports, power plants, steelworks etc. They can be mounted on rails or tracks, with exact design, boom length and control system tailored to suit the stockpile configuration, the type of material to be handled and the needs of the customer. Boom length can range from 10 to over 60 meters and the exact configuration, as well as the operational features, will always depend on the application. Basic data for the most popular models is given in the table below.

Bridge-type bucket wheel reclaimers PR300 series

Sandvik bridge-type bucket wheel reclaimer designs are for a more efficient blending purpose. This can be even more improved by means of a dual bucket wheel design. They are typically used in the coal, iron-, and steel industries for reclaiming material from stockpiles where homogenization is a primary requirement. The harrows are designed to promote homogenization and direct the flow of material to the base of the pile, where it is scooped up by the buckets and discharged on to a cross conveyor that either passes through the axis of the wheel, or is connected to the bucket wheel by means of an intermediate conveyor. Basic data for the most popular models is given in the table below.

Model Material Nominal

Portal scraper reclaimers PR400 series

Full portal scraper reclaimers usually reclaim the material from the surface of the stockpile in a longitudinal direction from one side of the pile only, down the full length of the pile. They discharge the material on to a conveyor belt along the stockpile. Because of the reclaiming path from the surface, traveling portal scrapers have limited ability to homogenize the material, unless a strict and rather complicated material layering scheme is implemented. They can be a good solution for small to medium capacities and where homogenization is not a priority. Basic data for the most popular models is given in the table below.

Model Material Nominal capacity (t/h) Rail gauge
m (ft) Number of scraper booms

PR400-430/36 Sulfur 430 36 (118) 1

PR400-1000/42 Urea 1000 42 (138) 1

PR400-1800/52 Coal 1800 52 (171) 1

PR400-3500/51 Coal 3500 51 (167) 2

Bridge scraper reclaimers PR500 series

Front-acting bridge scraper reclaimers that operate in a transverse, slice-wise manner are clearly superior to those that reclaim the material longitudinally, because they cut across the pile layers and blend the material effectively during reclamation. Basic data for the most popular model is given in the table below.

PR500-300/35 Coal 300 36 (118)

Drum-type reclaimers PR600 series

Essentially, the drum-type reclaimer is the alternative to single- and double bridge-type bucket wheel reclaimer. It comprises a long rotating drum fitted with a large number of reclaiming buckets arranged radially along its length, into which material is fed uniformly by the harrow. The drum-type reclaimer is a good solution if good homogenizing characteristics are of paramount importance. Basic data for the most popular model is given in the table below.

Model Material Nominal

PR600-1400/38 Iron ore 2500 38 (125) 5.7 (18.7) 1400 (ť55)
