In North Carolina sit three quarries approximately 80 km (50 miles) apart. Riverbend Construction Services was contracted to drill, blast, and crush hard granite at each site.
A dependable, flexible solution
Riverbend had the difficult task of reaching peak production at each location without the footprint available for stationary crushing equipment. Duff Boyd, owner at Riverbend, chose Metso’s line of mobile Lokotrack® crushing units to solve this unique challenge: “We’ll come in here (each site) and build a bunch of inventory, fold up shop, pack it up, head to the next site, do the same thing.”
Since his client wanted everything broken down to -1/2" after crushing in the pit, he simplified the end material production process by connecting multiple units together. He lined up the Metso LT300HP™ for secondary crushing with the LT220D™ for tertiary crushing. After that, material is fed to an ST4.8™ washing screen.
“With Metso offering the LT220D, it removed the need for five pieces of equipment,” Boyd says. The machines have proven to be dependable, flexible, and mobile to allow one solution to be shared between all three sites.
Choosing the right partner for the job
Choosing Metso for the job meant weighting a few factors. Boyd explains, “Number one, can it do the job? The equipment has to be physically capable of producing a quality product that meets specs. And secondly, you have to have the support. You can have the best piece of equipment in the world, but if you don’t have the support, then I’m not interested. And that’s where the local dealer, Stowers, and Metso come in. Metso’s support is unmatched.”
Maximizing results through simulation
Metso’s proprietary simulation software, Bruno, was another factor that helped Riverbend choose the equipment best suited to their needs. They used the Bruno software to input their unique site challenges, model exactly what equipment would work, and even how best to configure it.
Again, Boyd explains: “They can plug in their models, whether it be the LT300HP, or the LT106, and plug it all in and hit ‘go’. With Metso, they understand their equipment. It’s not just a generic AggFlow program, it’s unique to Metso, and the accuracy is impressive.”
