DRUMMONDVILLE, Quebec—After two years of testing, Soucy Group subsidiary Soucy Plastiques has unveiled a heavy duty impact bar for use in mining applications that it claims will help cut down on operations and maintenance costs.
The Soucy HD Impact Bar consists of a two-inch rubber layer encased in two layers of ultra high molecular weight polyethylene.
The bar is manufactured in a one-step compression molding process using proprietary rubber and UHMW-PE formulas developed by the Soucy Group.
The rubber portion of the bar absorbs the impact of falling materials onto a conveyor belt, Soucy said, while the plastic outer layers seal the load zone, resulting in longer belt life, reduced spillage and decreased costs.
Drummondville-based Soucy tested the new bar for two years at a crushed stone quarry in Canada.
The firm claimed the test showed the Soucy HD Impact Bar increased service life by 55 percent compared with current bars.
The bottom layer, which replaces an aluminum frame, provides a consistent load transfer, is flexible and snaps back to its original shape after impact, giving an improved seal between the conveyor belt and impact bed.
In addition, Soucy Plastiques said the product is metal-, rust- and spark-free. It has no glues and adhesives, and the firm is offering lifetime warranty against delamination of the three segments.
Without the absorbing properties of the rubber, the conveyor belt would spring back, and the rocks would tend to fall off the belt, said Gilles Boilard, a project manager for Soucy Plastiques.
The subsidiary worked with sister company Soucy Techno to develop the proper rubber compound for the bar, he said.
Soucy Plastiques previously had used two rubber compounds in other products, but neither was right for this application.
Boilard said the long field test was necessary because the company had to prove the new bar worked before trying to market it. Otherwise, the cost of lost production at the mine would outweigh the cost of the part greatly.
