AGG1: A Texas-Sized Show

This year’s AGG1 Show Was Bigger and Better, and on the Show Floor, Manufacturers Let the Equipment and Technology Do the Talking.

NSSGA Officials look on as the ribbon-cutting begins, opening up the AGG1 show.

The 2018 AGG1 Academy & Expo, co-located with the World of Asphalt, concluded a successful run, March 6-8, with a very positive atmosphere, as attendees and exhibitors conducted business and discussed issues affecting future growth such as infrastructure funding and industry experts shared best practices during well-attended education sessions.

The co-located exhibitions were held at the George R. Brown Convention Center in Houston. Exhibitors and attendees interviewed by Rock Products expressed satisfaction with their show experience, booth traffic and educational opportunities.

The National Stone, Sand and Gravel Association (NSSGA) and National Ready Mixed Concrete Association each held their annual convention in association with the event. Rock Productssponsored NSSGAs Young Leaders Luncheon speaker, former Navy SEAL David Sears.

Registered attendance was more than 8,300 at the close of the shows, down slightly from last year, with attendees coming from all 50 states, all 10 Canadian provinces and 50 other countries worldwide.

Both AGG1 and the World of Asphalt hosted a sold-out show floor that broke size records and spanned a combined 174,000 net sq. ft. of exhibits. More than 460 exhibitors, including more than 160 new to the shows, displayed their latest products and technologies for the aggregates, asphalt, and pavement maintenance and traffic safety sectors.

Education was an integral component of the event, with attendees purchasing more than 10,000 tickets for the shows’ signature learning programs: People, Plants and Paving Conference from the National Asphalt Pavement Association (NAPA) and AGG1 Academy from the NSSGA.

“These outstanding numbers emphasize the value of the convention and AGG1. This really is the best time for anyone in our industry to connect with peers, examine business issues that affect our operations and get energized for the future,” said Joel Galassini, Cemex regional president and AGG1 Academy & Expo chair.


At a press event held at its booth, McLanahan President Sean McLanahan (left) talked about the company’s growth and how it can meet the challenges of aggregates producers. At right is Mark Krause.

“This was one of our best events ever that delivered it all for industry professionals: product innovations, focused education and quality networking,” said Kevin Kelly, president of Walsh & Kelly and World of Asphalt 2018 chair. “It is always an incredible opportunity to come together and learn from each other, and we thank all participants for their continued support.” 

Industry support amplified the shows’ networking and knowledge sharing. More than 25 allied groups from the United States, Canada and worldwide participated as official supporting organizations.

AGG1 Academy & Expo focuses exclusively on the aggregates industry as its leading exposition and education resource, also co-located with the NSSGA Annual Convention. World of Asphalt Show & Conference is the largest education conference and exhibition focused on the asphalt, pavement maintenance and traffic safety industry sectors.

The shows are industry-owned and managed. World of Asphalt is owned by AEM, NAPA and NSSGA, and produced by AEM. NSSGA owns and produces AGG1.


The AGG1 show broke records for floor space.

The next AGG1 Academy & Expo and World of Asphalt Show & Conference will be held Feb. 12-14, 2019, at the Indianapolis Convention Center in Indianapolis. The shows are held annually except in ConExpo-Con/Agg years, when that show spotlights the exhibitors and products of AGG1 and World of Asphalt.

A number of manufacturers used AGG1 to show new products and services, as well as equipment enhancements and improvements:

CASE Construction Equipment is celebrating its 60th anniversary of wheel loader production with a variety of promotions and activities throughout the year. The activities started at World of Concrete 2018 and continued at AGG1.

The current offering of CASE wheel loaders evolved from the W9, the first CASE integrated four-wheel drive wheel loader introduced in 1958.

“The wheel loader is an iconic piece of the CASE lineup dating back to 1958, bridging the construction and agricultural industries that CASE has most proudly served for generations,” said Scott Harris, vice president – North America, CASE Construction Equipment. “These machines have come a long way since the original rigid-frame models built in our Racine tractor plant, and more than ever reflect the practical innovation CASE builds into its equipment to maximize performance and dependability.” 

The latest wheel loader offering from CASE – The G-Series – span 141 to 347 hp, with bucket capacities ranging from 2.1 to 6.25 cu. yd. In the short time since their introduction, the G-Series have won several awards, including the prestigious Good Design Award in the Industrial Category from the Chicago Athenaeum: Museum of Architecture and Design and The European Centre for Architecture Art Design and Urban Studies, and top new product recognitions from industry publications.

The full-sized G-Series line is complemented by the compact F-Series line, which features models ranging from 58 to 74 hp and 0.92 to 1.3 cu. yd.



The new Cat 988K XE is the first wheel loader offered by Caterpillar with a high-efficiency electric drive system. The product was introduced to the trade press last year at a special event in Peoria, Ill., and the rollout of the product continued at AGG1.

This new large wheel loader joins the 988K and the recently launched 986K wheel loaders to provide customers with the most cost-effective loader for each application, according to the company. Delivering high-production in all loading applications, the 988K XE is recommended for demanding job sites where fuel efficiency makes a difference in the machine’s total cost of operation.

The new loader features switched reluctance (SR) technology and leverages more than 15 years of Cat electric drive experience and more than four years of stringent testing in a range of applications for proven reliability in the field. The field proven and tested C18 ACERT engine, mechanical dropbox, driveline and axles from the 988K remain in the electric drive machine for consistent, trouble-free operation.

Offering increased truck loading and load-and-carry efficiency, the new 988K XE increases efficiency by 25 percent overall and by up to 49 percent in face-loading applications, as compared to the 988K. This reduces costs and helps operations reduce greenhouse gas emissions and carbon footprint. At the same time, Caterpillar production studies report the new loader delivers up to 10 percent higher productivity in load-and-carry applications.

HaverBoecker Ty Rail 1Haver & Boecker

Haver & Boecker introduced new configurations of its Ty-Rail quick-tensioning system for screen media. As a result of Ty-Rail’s success, Haver & Boecker developed and now offers three angle-box designs for different vibrating screen setups. This allows producers to benefit from Ty-Rail’s time savings during screen media change-outs, even on difficult-to-access areas of a vibrating screen.

The patented Ty-Rail system is designed specifically for Haver & Boecker’s Tyler brand of vibrating screens and now comes standard on all new F-Class and T-Class machines with three-bend tension rails. The system solves an age-old problem of time-intensive screen media change-outs. Replacing tension rails is typically time consuming and requires removing and replacing many pieces of hardware per screen section. Washers or bolts are often dropped or lost in the process, which adds to downtime and parts costs. Ty-Rail eliminates this problem by combining the tension rail and all of its hardware into one piece. The new Ty-Rail angle box designs provide the ability to change screen media in half the time, even in tight or hard-to-reach areas.

“Our goal is to continually develop new ways to help our customers achieve more productivity,” said Karen Thompson, Haver & Boecker Canada president. “Our patented Ty-Rail system is just one way we are achieving that goal. The feedback from customers and the positive impact on their operations encouraged us to develop additional configurations to accommodate more screen designs and applications.”

Aerial intelligence solutions provider Kespryshowcased the work of more than ١٧0 aggregates customers at AGG1. These organizations, including new Kespry aggregates customers CSA Materials, Stoneco of Michigan (a division of Oldcastle) and York Building Products, all use the Kespry industrial drone-based platform to manage stockpile inventories, plan mining operations and maximize revenue. 

To date, Kespry aggregates customers have flown 10,400 worksite missions measuring 223,000 stockpiles across 1.4 million acres. 

York Building Products operates stone quarries, and sand and gravel operations throughout Pennsylvania, Maryland and Delaware, providing high-quality aggregates to the Mid-Atlantic region for more than half a century. To ensure greater control over inventory management and mine planning processes, the company implemented the Kespry aerial intelligence platform so it can frequently and automatically calculate the perimeter and volume of all aggregate stockpiles. It also uses Kespry to estimate reserve levels, and to compare volume measurements from stripping and mine reclamation work.

“With the Kespry drone, we can fly as often as we want across all of our sites to make sure that our production numbers are right on target,” said Jim Gawthrop, vice president, York Building Products. “We no longer have costly surprises. Bottom line, it’s about getting the right information – and more information – just when we need it, instead of waiting for a manned aerial survey.”

Stoneco is a leading supplier of crushed limestone, sand and gravel in Michigan, that has been in business for more than 100 years. It serves the Michigan Department of Transportation and Ohio Department of Transportation, and commercial organizations, with aggregates materials designed for highways, parking lots, driveways, and other applications.

“Stoneco uses the Kespry system monthly at all of our operations for inventory management and it has allowed us to increase our accuracy, and have same day results,” said Austin Fisher, assistant operations manager and quality control manager, Stoneco of Michigan. “The speed of obtaining data from the Kespry system has allowed us to tweak changes to our operations days faster than old methods, providing us with virtual real-time inventory checks that increase our operations’ efficiencies.”

“The Kespry aerial intelligence platform delivers a single source of truth for aggregates companies’ worksite data,” said George Mathew, CEO and chairman, Kespry. “Our 170 aggregates customers are all experiencing the unprecedented benefit of survey-grade, aerial topographic data that enables them to accurately define volumes for stockpiles, blasting and stripping. It easily and rapidly enables them to take that data and use it to calculate volumes, manage material, create inventory reports, and validate or update design plans. We’re extremely pleased so many companies are reaping such significant benefits from our platform.”


Major Wire Industries

Major welcomed attendees to its booth to learn about maximizing their production and profit potential by using FLEX-MAT High Vibration Wire Screens. Executive Vice President of Sales and Marketing André Mathieu and Vice President of North American Sales Jimmy Siler were on-hand to speak to customers.

FLEX-MAT high-vibration wire screens have individual wires that vibrate independently at a high-frequency of between 6,000 to 10,000 strokes per minute. FLEX-MAT accelerates the stratification process and allows more material to pass through the screen.

Major ensures optimum wire quality and consistency at all times by developing, (through its own specifications and internal laboratory quality controls), the best recipe for a wire’s chemical content to optimize all factors, and by using the most advanced patented wire-making process, Major also only uses the highest quality of stainless steel wires with the highest tensile strength, available in Type 304 and Type 316.

FLEX-MAT vibrating wire screens will provide more spec product at a lower operating cost, while delivering more wear life and eliminating blinding, pegging and clogging issues, the company said.

At a press event held at its booth, McLanahan President Sean McLanahan talked about the company’s growth and how it can meet the challenges of aggregates producers.

“Today more than ever, producers want to know they have a partner in those challenges – whether that be someone to assist in turnkey plant set or to be there to troubleshoot when things go wrong,” he said. “More and more, that is what we’re trying to develop – whether through our process engineering team or a dealer network that is focused on keeping you running with local service and support.

“We are also focused on sites that want quick set-up and delivery,” he said. “We continue to be excited about the growth the aggregate industry is seeing and look forward to what the coming years are going to bring.”

Mark Krause, managing director – North America for McLanahan, added, “Obviously, a lot of our success here in Texas has come from our strong reputation in the frac sand market in places like Wisconsin and Minnesota, but it also comes in part due to our ability to offer customers equipment that has quick set up upon delivery. For us, that has largely come from creating a more standardized set of equipment modules that can be designed and manufactured to meet the needs of producers.

“For a long time, we touted our custom engineered process solutions,” he said. “While we still make sure that your equipment meets the processing needs of your site, standard equipment modules allow us to quickly configure a site to meet your processing needs, as well as provide a competitively priced solution. “



McCloskey Washing Systems (MWS) launched a new product line, the Compact Sand Plant (CSP), at the AGG1 and World of Asphalt Show. The new additions to the MWS product range are compact sand plants, CSP 60, CSP 120, CSP 200 and CSP 250 single and twin sand plants. The range has been designed to give the ultimate choice and flexibility to meet customers’ expectations.

Telsmith Inc. exhibited at AGG1, introducing The Extra Mile campaign, which honors those who go the extra mile – from Telsmith employees to people within the aggregates and mining industry, and beyond. The heart of this campaign is partnering with The Independence Fund to donate a Track Chair to a severely wounded U.S. Veteran from the Houston area who is on the waiting list.

The Independence Fund helps veterans get back outside to enjoy the outdoors through a variety of devices that include all terrain wheelchairs and adaptive bicycles. Many severely wounded veterans have lost the ability to experience activities they previously enjoyed – from hunting and fishing to simply going outside in their backyards. Wounded veterans who use The Independence Fund’s all-terrain mobility devices regain the ability to do the things they love, transforming their lives toward a better future.

Telsmith supports this program that believes, “we owe it to our veterans to provide the resources they need to move forward and build a strong foundation toward lasting physical and emotional healing in order to reestablish their independence.”

Telsmith believes U.S. Veterans are individuals who have gone the extra mile in their lives, and this is a core value of the Telsmith team.

To showcase the Telsmith promise that “The Extra Mile Isn’t Extra. It’s Included.,” the company displayed the T-Series cone crusher hybrid bearing, and had employees on hand to discuss how Telsmith goes the extra mile with their concept-to-completion services.

Telsmith T-Series cone crusher patented hybrid bearing technology provides the ability to crush at lower horsepower from improved lift that helps carry the crushing forces, when compared to roller bearing machines. Engineered to hold up to tough, abrasive aggregate and mining processes, the T-Series cones with hybrid bearings deliver tested productivity, safety and ease of maintenance with maximum uptime.


Van der Graaf

The engineers at Van der Graaf expanded research and development in the last five years to produce the all-new GrizzlyDrive design drum motor, which addresses industry-specific operating challenges.

The GrizzlyDrive is a different kind of drum motor. It has been designed exclusively to reliably perform and operate in very harsh environments and demanding conditions. Currently GrizzlyDrives operate from the extreme cold (-50 F) temperatures of Labrador to the extreme hot (+40 F) temperatures of San Antonio.

All components of the drum motor are protected inside the drum. The robust mechanical seals are designed to prevent abrasive dust and water to penetrate the unit. The massive end-flanges on the GrizzlyDrive are engineered to deflect debris and rock overspill, and inhibit accumulation to occur between the drum motor and the conveyor frame.

The heavy-duty bearings have been designed for high static and dynamic rating to absorb heavy shock loads and high belt tension. The planetary and coaxial gear configuration design can absorb the high starting torque (240 percent) produced by the high torque design “C” electric motor that is able to start the conveyor under full load conditions.

The electric motor windings are manufactured with heavy-duty magnet wire and encapsulated with the vacuum pressure impregnation (VPI) process to withstand vibration and shock loads. The rubber lagging is hot bond vulcanized with or without ceramic tiles, is reinforced and installed in sections between welded bars in order to absorb the sheer loads produced by the belt.

The GrizzlyDrive drum motor has been designed exclusively for mining and aggregate applications, and is built like no other, according to the company.

Wirtgen (Kleemann)

A series of four new MOBISCREEN EVO aggregate classifying plants from Kleemann complements Kleemann’s mobile jaw, impact and cone crushing plants with easy mobility, flexible application options and high output.

Now being introduced to North America, Kleemann’s four new classifying screens are the track-mounted double-deck classifying screens MS 702i EVO and MS 952i EVO, and the triple-deck classifying screens MS 703i EVO and MS 953i EVO.

The two plant sizes have a screening area in the upper deck of 75 or 102 sq. ft., respectively. As with the crushing plants, the classifying screens with their convenient transport dimensions and short setup times optimize the productivity of contractor crushing operations.

The MS 702i/703i EVO achieves a maximum output of 386 tph and the MS 952i/953i EVO an hourly output of up to 551 tons. An optimized material flow through the plant makes this possible.

It starts with feeding, which thanks to the generously sized feed hopper, is possible both with a wheel loader as well as an upstream crushing plant. The material on the extra-wide feeding conveyor is conveyed to the screen box. The screening angle of the box can be adapted to the application. An impact plate at the conveyor discharge distributes the material evenly on the screen surface, keeping wear to a minimum and achieving a high output.

Kleemann also puts safety first with MOBISCREEN EVO screening plants. These new screening plants are operated by a mobile control panel that can be installed at three different points on the machine, guaranteeing ideal visibility during operation.

All plant functions are started automatically, without each side discharge conveyor having to be activated individually. Data on machine operation can be read off at the operator panel. The plant is moved without jolts thanks to the proportionally activated hydraulic valves.

When interlinked with MOBICAT jaw, MOBIREX impact, or MOBICONE cone crushing plants from the EVO series, whose size and output are tuned to the EVO screening plants, the plants work particularly efficiently and achieve a high output. An emergency-off function enhances safe working conditions.

The large engine compartment ease maintenance, and further service components are easily accessible via the all-round work platform. Thanks to the easy access to the screen deck, it’s now easier for users to change screen media. The fines conveyor can be lowered, for example, to allow access to the lower screen deck. From a large number of screen media, Kleemann offers the suitable surface for each application.


Look for more AGG1 product updates in upcoming issues of Rock Products.
