Bulk Material Handling Stacker System

MineAlpine stackers effectively stockpile bulk materials in an efficient and orderly manner. Stationary or traveling, borne on rails or crawlers, they can be supplied in fixed, luffable or luffable-and-slewable boom designs, with capacities from 150 to 20 000 metric tonnes per hour (165 to 22 000 short tons per hour). The choice of design depends on factors such as the stacking method (Chevron, Windrow and Cone Shell) and size of the stockpile, the type of material, the required throughput and the demand for mobility. Tripper cars or tripper systems for transferring material from the yard conveyor to the stacker are considered part of the stacker.

Luffable and slewable stackers AST100-ASTT300 series

This type of stacker is able to luff and slew the boom and designed to service stockpiles on both sides of the rails. The higher initial cost of this stacker is quickly recovered by economies gained from their flexible mode of operation, as well as their ability to effect good layering and excellent blending. 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. Three configuration AST100 (pylon-type), AST200 (cantilevered-type) and AST300 (rocker-type) can be provided. Basic data for the most popular models is given in the table below.

Luffable stackers AST400 series

Luffable-only stackers are used for applications where the stockpile is required to be stacked from one side only, with little or no demand for blending. The absence of a slewing mechanism makes them an economical option in the right applications. Boom length can range from 10 to over 60 meters, and the exact configuration, as well as the operational features, will depend on the application. Basic data for the most popular models is given in the table below.
