Auxvausse, MO, Con-Agg Companies, a leading supplier in crushed limestone, concrete products, and warehousing is producing more tons per hour and increasing efficiency with their new Telsmith 8×20 and 6×20 Vibro-King TL® Portable Screen Plants, Titan™ T400 Portable Cone Plant, and TRAC10® Automation System.

Con-Agg Companies, a division of Summit Materials, is a diversified supplier of crushed limestone products, concrete, warehousing facilities, and record-management services. Headquartered in Columbia, Missouri, Con-Agg has over 50 quarry and ready-mix locations and over 500 employees serving a large geographical footprint in Central / Northwest Missouri and Central / Northeast Arkansas. Through the years, their mining operations have been recognized by the Missouri Limestone Producers Association as Best-in-Class for both large and medium-sized operations. Recent honors include the Hillenkamp-Rush Meritorious Safety Award and special commendations for 22 consecutive years with no lost-time accidents.

On the aggregate side, they operate three companies under the names of Boone Quarries, Norris Quarries, and Mid-Missouri Limestone. They produce some of the highest quality materials in the state, which include: concrete and asphalt aggregates, as well as base products, clean aggregates, road rock, rip rap, and agriculture lime.

Ronnie Simms, Quarry Manager of Con-Agg Companies is in charge of the Mid-Missouri Limestone Auxvasse South Quarry in Auxvausse, MO, along with 16 other quarries in Missouri. This location is processing concrete rock that goes into their precast and concrete plants.

Being in the industry for 37 years, Ronnie saw that this quarry needed an upgrade. “Our old stationary plant included worn-out equipment that was no longer dependable or producing to our needs,” says Ronnie. “We have been running Telsmith equipment for 22 years, so the decision was clear to choose Telsmith again.” Con-Agg’s first experience with Telsmith was in 1997 when they purchased a full modular plant at their Boonie Quarries West operation that is still running today.

Their old plant in the Auxvasse South Quarry was only producing 200 TPH, so Ronnie got in contact with Telsmith’s Regional Sales Manager, Jerry Hall, to see how Telsmith could help Con-Agg out again. The timing was perfect, as Telsmith had an 8×20 Vibro King TL® Portable Screen Plant and a Titan™ T400 Portable Cone Plant in stock, ready to ship. Con-Agg then abandoned their 50-year-old stationary plant and moved their new Telsmith portable plants to a better location within that quarry. They went from primarily impact crushing to compression crushing as their old plant had a primary jaw crusher and secondary impact crushers.

The main features of the Telsmith equipment that stood out to Con-Agg were the automation system and the features of the Titan™ T400 cone crusher including the TRAC10® automation and it’s top-service capability.

“With Telsmith’s automation system, they were able to link some of our old pieces of equipment into the automation plan,” says Ronnie. “We put laser level sensors over our secondary crusher, tying it back to our Syntron feeder, then put a level sensor on the bin interlocking it back to our grizzly feeder. This balanced out the plant and increased our production. Telsmith’s automation technology has helped us be the most efficient we’ve ever been. So efficient that we went from 200 TPH to over 400 TPH,” says Ronnie.

“The TRAC10® automation on the Titan™ T400 Cone Crusher also really impressed us,” says Ronnie. TRAC10® monitors crusher operations, provides automated calibration and setting controls, and protects the crusher from overload; all to yield greater crushing performance and efficiency. Operators can initiate an automated calibration process via the touch screen monitor, that automatically “zero’s-out” and resets to the proper setting. Operators can also modify the crusher setting at any time, even while crushing.

“We really like the simplicity and safety aspect with the ability to service the cone from the top,” says Ronnie. Titan™ Cone Crushers are built so the components are removed from the top instead of the bottom, reducing the need to work under the crusher, which is safer and more efficient. The main shaft on the Titan™ series cones is fixed into the lower mainframe and the countershaft sits below the main gear allowing all other components to be removed through the top.

The combination of Telsmith’s automation system, TRAC10®, and top-service capability on Titan™ cones increased Con-Agg’s efficiency and tons per hour from 200 to over 400. “We currently run it five days a week at ten hours per day. At the end of each shift, we inspect the plant for any problems that may shut us down the next day and perform regular maintenance, which is the key to our uptime success,” says Ronnie.

Con-Agg also enjoys working with Telsmith because of their knowledgeable sales team, parts availability and factory service support. “The sales, service, and parts departments have been great to work with. If you have any problems, they will work through your issues over the phone, or send somebody out. Telsmith’s sales team has many years of experience that brings value to the table. Parts and service availability has also been a great marriage for us,” says Ronnie.

Looking ahead, Con-Agg plans to expand and is always looking for new opportunities to grow. “Our next step is to add a high-frequency screen in to make an asphalt fraction and our concrete rock at the same time,” says Ronnie.
