Drummond Company, Inc.
Shoal Creek, Alabama
As part of a new mine project, Roberts & Schaefer Company,
on a turnkey basis, supplied the slope conveyor running from the
mine mouth. This conveyor sends ROM coal from the mine to a grizzly,
which removes the oversize material, and then onto a raw coal
storage belt (supplied by others). The conveyor is 72" wide,
4,600' long and has a 1,100' vertical rise. It moves 5,500 TPH
of coal and operates at a speed of 800 fpm. The steel cord belt
is considered to be the strongest in North America and weighs
80#/ft. Two 2,000 HP motors mounted on each of the two tandem
drive pulleys (a total of 8,000 HP), drive the belt
