Problem:
Conveyor belts and crushing equipment were being damaged by tramp iron contaminated coal arriving at the Clairton, PA, USA coke works of
U.S. Steel Corporation.
Solution:
An Eriez
Suspended Electromagnet was installed above a conveyor that connected a barge unloader and the crushing building. All tramp iron was removed from an average nine-inch (23 cm) burden depth of coal traveling at 596 feet per minute (182 mpm).
Problem:
Consolidated Edison needed to protect pulverizing equipment at their Astoria Long Island, NY, USA plant.
Solution:
An Eriez 42-inch (1067 mm) diameter
Electromagnetic Pulley was installed downstream of the primary breaker. Afterwards, tramp iron such as nails, nuts and bolts was completely removed before the coal reached the pulverizing mills.
Problem:
Snap Creek Mining, a U.S. coal mining operation, looked to replace an existing vibratory feeder with an economical unit that could withstand the constant beating of day-to-day operation.
Solution:
They chose an Eriez'
Ultra Force Mechanical Vibratory Feeder, a rugged two-mass design using heavy duty readily available coil springs.
Developed specifically for the coal and aggregate industries, this line of feeders handles capacities up to 2,500 tons per hour (2,268 mtph), depending on tray size.
