Bulk Material Handling Stacker&Reclaimer System

MineAlpine stacker/reclaimers come in two main types: bucket-wheel models for alternate stacking and reclaiming, and circular units, which normally stack and reclaim the material alternately but can be designed to do so simultaneously if required. Our bucket-wheel models, normally supplied complete with tripper cars, are compact and economical for longitudinal stockyards where simultaneous stacking and reclaiming is not required and where there can be large variations in the demand for stacking and reclaiming capacity. Our standard circular units, which build a ring-shaped stockpile and are normally housed inside a covered dome due to environmental concerns, both continually stack the stockpile at one end of the ring and reclaim the material simultaneously from the other end.

Boom-type bucket-wheel stacker/reclaimers

Borne on rails or crawlers, MineAlpine bucket-wheel stacker/reclaimer rigs ASR100 (pylon-type) and ASR200 (rocker-type) can be supplied in many configurations and sizes, with booms up to 60 meters in length and stacking/reclaiming capacities up to 20 000 metric tonnes per hour respectively (22 050 short tonnes per hour). Like all MineAlpine materials handling machines, they are controlled by state-of-the art PLC systems with user-friendly interfaces and can be supplied with advanced automation capabilities. All units are custom built and made to order. Basic data for the most popular standard models is given in the table below.

Circular stacker/reclaimers ASR300 series

In circular stockpiles, normally housed inside a dome, the pile is built up automatically at one end by means of a slewing and luffing stacker using the cone-shell stacking method for 360 degrees of rotation, and reclaimed alternately at the other end by a radial scraper-type reclaimer. The latter reclaims the material layer by layer from the pile cross-section and conveys it into a central hopper located under the central column. If required, the rig can be designed to stack and reclaim simultaneously. Basic data for the most popular standard models is given in the table below.
