By using Cleveland Cascade chutes, Lafarge Corporation in Grand Chain, Illinois, are successfully loading finished cement into barges within EPA guidelines.
The system at Lafarge/Joppa features a dual Cascade chute arrangement. The finished cement discharges from the weigh bin on to dual airslides to the dual Cascade chutes and into open-top barges. Each chute handles 300 tons/h. The chute system includes dual material probes, load-cell system, pneumatic and electric hose reels and special adapter cement skirts.
The truncated, oppositely inclined cones, supported by straps and covered by a wind shroud, allow material to be loaded in mass flow at low velocity, minimizing dust emission.
