the stockpile has been raised so reliably that its cross‐sec‐
tion shows as many layers of equal material as possible. The
stackers can be of fixed or mobile types, depending on the
requirement. In case of circular stockpiles the stackers are
mounted onto a column and with a longitudinal blending
bed, they are mounted on rails. The stackers are designed as
fixed, raisable and pivotable booms with conveying capac‐
ities of up to 4,000 tph. The choice of the right system de‐
pends on different factors, as for example, the shape and
size of the stockpile, the material, the throughput and the
desired mobility.
Lastly, the bridge scraper homogenizes the material. It
has a mobile rake on each side. The material is removed
in layers by stroking the face of the stockpile with the
rake. The scraper blades move the bulk material to‐
wards the belt conveyor which runs parallel to the stock‐
pile. Beumer bridge scrapers are not only robust, but
they also transport the bulk material so that the product
is handled gently. This makes them suitable for a vari‐
ety of bulk materials. Their continuous and comparably
simple working motions allow for a fully automated op‐
eration and ensure a constant and steady flow of the
bulk material.
