Under a turnkey contract, Roberts & Schaefer designed, supplied,
installed, and commissioned a gypsum handling and barge loading
system.
A 600 TPH, 1,014-foot long, 36-inch wide gypsum conveyor is fed
either by an existing radial stacker or by front-end loaders into
a dozer trap. The gypsum conveyor then transports the material
into a moveable-loading chute with a telescoping spout. The chute/spout
is designed to fill covered barges through open hatches, which
requires that the chute/spout be able to move laterally and extend
and retract. A certified belt scale weighs the amount loaded into
each barge.
 A
new barge haul system positions the barges. R&S constructed
a new river cell to support the conveyor structure and the barge
haul equipment. A programmable logic controller (PLC) controls
the entire operation.
