“We bought it because of how its grizzly screen separates the small fraction from the bigger stones so well,” Bälder says. The double-deck independent grizzly section operates separately from the hopper and efficiently screens out the fine material prior to it entering the crushing chamber. And by using the screen box, the crusher gives operations the ability to produce two sellable products.

“Then there’s the crusher, the ‘Quattro Movement,’ which gives good shape to the stones,” Bälder says, adding that ease of maintenance also played a significant role in the unit’s selection. “All three sides are totally 100-percent accessible. And that’s a nice thing for maintenance, for service. The competitors do not have this easy access.”

The crusher is remote controlled by the operator in the excavator. Moersdorf’s operators, Bälder says, can safely and easily adjust the position or move the machine to another task.

Dependability is key in the competitive rock crushing and concrete business, Bälder says: “It’s reliable. We cannot afford any breakdowns because our customers want to have the product in the time, in the quantity, and quality we have promised them.”

There have not been any major service or repair issues, but Bälder says he is confident of Atlas Copco’s ability to provide service and 24-hour turnaround on spare parts.

For Moersdorf, a company that specializes in shaping rocks for tight compaction, the crusher itself has been a perfect fit. AM
