Performance and serviceability are the primary reasons that 120 85 LLC, a Colorado company, chose the Lokotrack LT1213S mobile impactor plant with screen over a competitor’s machine for its recycling application. For the past 3½ years, 120 85 LLC has crushed asphalt and concrete, operating out of the Henderson Pit in Henderson, Colorado. “We recycle asphalt to a ¾-inch-minus finished product for various projects, including parking lots, driveways, road applications, anything like that,“ says Adam Schultejann of 120 85 LLC. Adam, along with his father, Dave Schultejann, owns 120 85 LLC and runs the day-to-day operations at the pit.
Finding a cost-effective, sustainable way to recycle asphalt and concrete, while also reclaiming land formerly used for gravel mining, provided a business opportunity for the Schultejanns. Mining activity at the Henderson Pit ended in 2007, and the 39-acre property sat vacant and mostly inactive since that time. Initially, the site’s reclamation plan called for converting the pit into a water reservoir. However, that plan was never implemented due to economic factors and other considerations. Several years ago, the Schultejanns stepped in with a reclamation plan that called for filling the pit with clean, non-hazardous material, bringing in up to 1 million cubic yards of fill material to return the property to its original grade. The pit’s location (northeast of the metropolitan Denver area) is convenient for area contractors bringing in clean construction and demolition (C&D) material for on-site processing.
COMPARING CRUSHERS
The Schultejanns are currently using a Lokotrack LT1213S to crush and screen primarily asphalt, and an LT1415 impactor plant to crush concrete, loading both crushers with a John Deere 1350 excavator. The Lokotracks are provided by Inter-Mountain Construction Equipment of Fort Lupton, Colorado, Metso’s crushing and screening distributor in the state of Colorado and southeastern Wyoming (Inter-Mountain Construction Equipment was recently acquired by Wagner CAT, who will serve as Metso’s new crushing and screening dealer in the region). Adam Schultejann says he’s been pleased with the performance of the LT1213S, as well its ease of maintenance.
Prior to leasing the LT1213S, the Schultejanns first tested another manufacturer’s mobile impactor plant with screen for about 4 months. However, that unit did not meet performance expectations. “We’ve had good experience with Metso equipment, and the LT1213S runs fine,” notes Schultejann, adding that “the LT1213S really doesn’t give us any of the issues we had with the other unit at all.” Schultejann has been operating the LT1213S for several months, and has achieved production rates as high as 300 tons per hour (tph).
In addition to the productivity of the LT1213S, Adam Schultejann has been impressed with the efficiency of the combination impactor with screen. “In the past, we’ve had just a regular LT1213 track-mounted machine, and we’ve run an ST3.8 screen with it,” he says. “This is a much more efficient setup, with less labor on the machine, fewer people needed to run the machine, and more fuel-efficient. Compared to operating two machines, it’s been half the fuel, at least, if not better.”

DESIRED IMPACT
The Lokotrack LT1213S is a fully equipped mobile impactor plant with a high-output single deck screen and a return conveyor. The plant is built around the updated Nordberg NP1213M impact crusher, powered by a clean Caterpillar C13 diesel engine. Metso engineered the NP1213M crusher specifically for mobile applications, with a rugged, reinforced frame and high-quality blow bars for efficient crushing.
The new dual-slope screen on the LT1213S provides high on-board screening capacity and makes the LT1213S easy to operate in both closed and open circuits. The LT1213S can be customized for recycling applications, including asphalt, with features like a vibrating grizzly or pan feeder under the crusher. The vibrating grid effectively separates scrap from the feed, resulting in much cleaner screened end products.
STILL GROWING
Finding the right equipment at the right time has been integral to the Schultejanns’ ability to serve the expanding market for recycled concrete and asphalt. Adam and Dave Schultejann have relied on Greg Jones at Inter-Mountain Construction Equipment for a number of years, going back to their previous construction contracting company. “We’ve been working with Inter-Mountain for 6 or 7 years now,” says Adam Schultejann. “Greg has been great, he is the biggest reason we use them.”
Since acquiring the Henderson Pit, the Schultejanns have seen a steady increase in the demand for their recycled concrete and asphalt products. “We sell the end products to mostly contractors, who buy it for things like parking lots and storage yards,” says Adam Schultejann. “Business has been great,” he adds. “We recycle old concrete, so a lot of our business is reconstruction, buildings being torn down, new stuff being put up, and a lot of highway work.” Although we just started our business 3½ years ago, we’ve already grown into one of the largest recyclers in Colorado.” ■
