From Rail to Sale

A Major Rail-Based Distribution Network Beefs Up Material Handling to Meet Growing Customer Demand

Rail-based aggregate distribution is on the rise. In fact, a recent Florida-focused report refers to efficient rail transport as “the linchpin” behind the rapid movement of material from mine to market. The study states that Florida’s current pool of 4,000 rail cars must be increased to handle the additional material coming from out-of-state rail networks and through port terminals that need redistribution by rail.

Headquartered in Daytona Beach, Conrad Yelvington Distributors, Inc. (CYDI) is the largest rail distributor of aggregates in the southeast region of the U.S., moving more than 10 million tons of materials through a network of 27 rail-served distribution terminals in Florida, Alabama, Mississippi and Michigan. The company, which is a division of CRH Americas, currently leases more than 1,815 hopper cars, owns and operates at least two dozen locomotives, and dispatches its own fleet of material delivery trucks. Its rail logistics department is linked to the CSX Transportation computer for up-to-date information on rail shipments and railcar locations, and trucking delivery tickets are computer-generated at each terminal. Most terminal sites offload one-to-two 100-car unit trains each week, with each rail car holding up to 100-tons of material.

Aptly put, the CYDI slogan is “aggregates in motion,” a phrase that fits its rail distribution network as well as the ongoing material handling upgrades at its terminals – the latter being an initiative toward greater stockpiling capacity and efficient unloading at lower costs per ton. To that end, CYDI has recently installed no less than a dozen automated telescoping radial stacking conveyors and at least five automated truck unloaders, all manufactured by Superior Industries. The new material handling equipment is placed in a number of terminals and applications, with plans for even more units being added as new terminals open within the network. At certain sites, Superior Industries has also engineered the tunnel conveyors and overland conveyors for the transfer of material from the rail cars to the telescoping stacking conveyors.

When a 100-car train arrives at the company’s DeFuniak, Florida-based terminal, the train splits onto five different tracks. A locomotive backs in and hooks onto one of the sections at a time, and pulls each car over the tunnel conveyor where its load is conveyed to the TeleStacker conveyor, which builds up to eight different products stockpiles on the main part of the site. Then the telescoping conveyor is remotely adjusted to feed its load onto a 300-foot overland conveyor which transfers material to an additional yard which accommodates another eight high-volume stockpiles. The entire 10,000-ton shipment takes approximately 10 hours to unload and stockpile, all without the use of a loader or truck.

TeleStacker® Conveyor
RazerTail® Truck Unloader

Summary

At Conrad Yelvington’s two Alabama rail terminals petcoke and coal are distributed and stockpiled. Using two Razertail Truck Unloaders to streamline its operations, they are able to quickly and easily transfer materials onto a 170-ft TeleStacker Conveyor. The conveyors automatically start and stop using an infrared eye on the Razertail to detect material, removing the need for a dedicated operator and preventing the truck driver from having to leave his cab.

pump up the volume


CYDI distributes a variety of materials including granite, limestone, decorative stone, river gravels, and silica sands. No matter what the material, the company’s goal is to maximize stockpiling capacity at each of its distribution sites to meet growing demand.

After all, regional reports indicate that from the mining process to the marketplace, and on to the placement of material at the construction site – only a week may transpire – therefore unloading, conveying and stockpiling are key links in the logistics chain.

With more than 30 years of experience in the aggregate industry, Terry Cummings is operations manager over CYDI Gulf Coast operations. He cites several major reasons for replacing conventional stackers with the 42” x 170’ TeleStacker conveyors from Superior Industries. Top among them is up to 30-percent more stockpile volume on the same limited footprint. “With the stinger conveyor on the TeleStacker unit, you can build a much larger volume pile than that built by a fixed stacker. You’ve got that extra length that you can run, and that makes a big difference in volume,” he says, adding that an additional advantage is stockpiling without material loss due to segregation or degradation.

Minimized loader use is equally important. “With fuel, operator labor hours, and the current tire situation – we need to cut our operating costs and these conveyors allow us to do that,” says Cummings.

Then there is the issue of safety and loss prevention. “The safety in being able to adjust the telescoping stacker in bad weather is crucial. Once you retract the stinger conveyor, you bring the unit into a low profile,” he says, explaining that they had lost a couple of conventional gantry-type stackers to high winds during the recent major hurricanes. “That’s when we decided we had to make the switch to the TeleStacker conveyors. We can bring them in low to the ground and we don’t have all the cables to deal with, which was also a huge maintenance issue as well on the previous conveyors.”

Effective truck unloading


Alabama offers over 3,000 miles of railroad track serviced by five Class I railroads, which gives shippers excellent main line connections to all major market centers. CYDI currently maintains three rail-distribution terminals in the state, with a fourth under development.

At two of its Alabama sites, CYDI stockpiles and distributes petroleum coke (petcoke), a residual product of the oil refining process, which has made significant inroads into traditional utility coal markets. Particularly along the Gulf Coast, supplies of fuel grade petcoke are growing in response to the installation of new refining capacity. Petcoke is now being blended with coal for use in fossil-fuel power plants that can accommodate higher sulfur fuels.

The company’s Calera, Alabama site is both a coal and petcoke operation. “We’ve got a system there that blends coals with varying ash and sulfur contents to meet customer specifications. Then we stockpile it and sell it to the local market,” says Cummings.

Coal products are trucked into the site and unloaded. CYDI uses two Superior RazerTail Truck Unloaders to streamline its operations. The unloading systems can quickly and easily transfer material from belly dump trucks or end dump trucks and onto a conveyor. “I have installed an infrared eye on the RazerTail. When the nose of the truck runs across the grate and dumps into the hopper, it breaks in front of that electronic eye, which automatically kicks the conveyors on,” says Cummings who further explains that the system is equipped with a timer so that the belts will cut off after material transfer is finished. The system does not require a dedicated operator, nor does it require the truck driver to leave his cab to start the process.

Cummings stresses the importance of the RazerTail being equipped with its own low-profile ramp. “Any other type of unloader would require us to pour a concrete tunnel and then install a conveyor within it – and that is rather sticky to do. This system has everything you need – and it’s portable – so if you need to, you can move it anytime you wish,” he says, adding that he is currently in the process of combining the RazerTail with a 42” X 170” TeleStacker conveyor to gain an even greater payback in product quality control and costs-per-ton savings.
