What you missed at Wirtgen Group’s Technology Days

By |  March 29, 2018

Kleemann showcased four new classifying screens in the Mobiscreen EVO line at Wirtgen Group‘s North American Technology Days event outside of Nashville, Tennessee.

The track-mounted MS 702i EVO and MS 952i EVO double-deck classifying screens debuted along with the MS 703i EVO and MS 953i EVO triple-deck classifying screens.

The MS 702i and MS 703i EVO achieve a maximum output of 350 tph, while the MS 952i and MS 953i EVO are capable of producing up to 500 tph.

Kleemann attributes each plant’s output to good material flow, which starts with the feed and what the company describes as a “generously sized feed hopper.” Material feed into these plants is possible both with a wheel loader as well as an upstream crushing plant.

The material on an extra-wide feeding conveyor is conveyed to a screen box. The screening angle of the box can be adapted to the application, Kleemann says. An impact plate at the conveyor discharge distributes the material evenly on the screen surface. Wear is thus kept to a minimum, the company adds, and a high output is achieved.

Additionally, a mobile control panel that can be installed at three different points on the machine operates the Mobiscreen EVO plants. Data on machine operation can be read at the operator panel.

Also, the plants move without jolts thanks to proportionally activated hydraulic valves.

A large engine compartment facilitates maintenance, and further service components are easily accessible via the all-round work platform. Thanks to easy access to the screen deck, Kleemann says it is now easier for users to change screen media.

The fine grain conveyor can be lowered, for example, to allow access to the lower screen deck. From a large number of screen media, Kleemann offers a suitable surface for each application.

About Technology Days

The debut of the new screening plants was just one component of Wirtgen Group’s Technology Days event, which brought more than 1,000 guests to the company’s North American headquarters in Antioch, Tennessee.

Wirtgen Group, whose brands include Kleemann, Wirtgen, Vögele, Hamm and Benninghoven, showcased 29 machines for guests in two live demonstrations. Among the Kleemann equipment the company demonstrated was the Mobicat MC 110 Zi jaw crusher, the Mobicone MCO 9 Si cone crusher and the Mobiscreen MS 702i screening plant.

The company also offered tours of its Center for Training and Technology (CTT) located on the grounds. The CTT offers classes and curriculum to both dealers and end users, including technical service, operations, sales and parts. The 21,000-sq. ft. facility houses two classrooms and two laboratories, as well as a four-bay shop dedicated exclusively to training so hands-on training can take place regardless of the weather.

Jim McEvoy, president and CEO of Wirtgen America, sees the CTT as a commitment to the company’s customers.

“As the Wirtgen Group has developed its position in the marketplace in North America, we’ve done so on a platform of technology innovation,” McEvoy says. “Simply put, if you’re going to be that guy you have to back it up with training [and] with competencies so people understand how [to] use technology correctly for the most efficiency.”

With labor being such a hot-button issue at the moment, the CTT represents a solution to train the industry’s next generation.

“Labor is a big issue in the industry right now,” says McEvoy, adding that the CTT brought in about 3,000 people for training in 2017. “People are moving out who have been on the back of an asphalt paver or another machine for a long time. [With] that next generation you’re bringing in, these machines are sophisticated and require a lot of support from ourselves and the dealer.”

A series of short educational sessions at Technology Days also offered attendees training opportunities. In Kleemann-specific sessions, the brand’s representatives offered details on the Spective control system that debuted in 2017. Kleemann reps also offered tutorials on their cone and impact crushers.
