most anywhere.” This is made possible by the Versa Jet’s centrifugal fan with axial discharge, which produces an airflow that is parallel to the axis of the burner. This allows an efficient use of space within the tube, removing the lamination of airflow when other burner configurations use only the outer half of the tube. Because the Versa Jet has removed the need for internal components to “straighten out” airflow, less horsepower is required for operation. All three models use 25 hp.

AMMANN
The ACP ContiHRT plant from Ammann Group, Langenthal, Switzerland, is a continuous plant for the North American market, designed to handle up to 60 percent RAP without burning the light ends off the replacement binder. The Ammann plant incorporates a high percentage of recycled material by taking an innovative approach to the heating process. The RAH60 dryer, the unique heating system used on the ACP ContiHRT, is designed to gently heat the RAP to prevent damage to the AC. The RAP can still reach its target temperature of 120 degrees C when the new aggregate comes into play. Fresh aggregate is heated in a separate dryer—and at a much higher temperature—where there is no AC to worry about. After heating, the hot, fresh aggregate is mixed with the RAP and in so doing brings the recycled material to its target temperature. The fresh aggregate acts as a second heat source. The gentle heating process does more than protect the coating. It also minimizes fuel usage and emissions.

H&B
Haver & Boecker Niagara, Haver & Boecker’s new mineral processing brand, exhibited the Niagara F-Class portable plant for the first time during CONEXPO-CON/ AGG 2020. The circular motion inclined vibrating screen of the plant is designed to increase production by 25 percent over linear-stroke horizontal machines. The screen uses gravity to help move material down the screen deck, reducing pegging as well as energy and horsepower requirements. Operations like Pidherney’s of Alberta are reporting production increases.
To address screen media change-out needs, the portable plant is manufactured with six hydraulic run-on jacks to raise and lower the vibrating screen quickly. Producers gain the production benefits of an inclined screen with the maintenance benefits of a horizontal screen, according to the manufacturer. In addition, plants outfitted with Haver & Boecker Niagara’s Ty-Rail™ quick-tensioning system can cut screen change-out times in half, according to the manufacturer.
The Niagara F-Class has an advanced double eccentric shaft design, supported by four high-performance, double-spherical roller bearings. It is beneficial for screening situations that require consistent, load-independent performance at constant g-force. The F-Class portable plant can be customized to include a crusher, conveyors or other components.

KENCO
Originally designed for the vertical construction industry, the foundation drilling auger protection concept from Kenco Engineering Inc., Roseville, California, can reduce downtime at the asphalt plant and at the paver by retaining auger diameter. Kenco’s unique tungsten carbide impregnated (TCI) process protects auger flights from abrasive wear. Crushed tungsten carbide (TC) is impregnated into the flight edges (and outer faces, if desired) by melting the flight metal to a depth between 0.25 and 0.375 inches and dropping crushed TC particles into the molten puddle. After cooling, the TC is solidified deep into the parent metal.
TC wear strips featuring the Kenco TCI process can be welded to flight edges and any other drill tooling that needs extra protection. It’s not an overlay or spray-on. The TC becomes a part of the steel. Kenco crushes and sizes the TC raw material inhouse to maintain quality. TC has a hardness exceeding 90 Rockwell A.

MAJOR
MAJOR, a Haver & Boecker company, Candiac, Quebec, introduced its FLEX-MAT ID Enabled concept at CONEXPO-CON/ AGG 2020. The RFID technology tracks and stores screen media data such as panel dimensions and customer-defined details to offer users information at their fingertips for simple reorders. All FLEX-MAT screen media is now embedded with the ID Enabled microchip. Product information is easily accessed through the company’s new MAJOR App without the need of an additional reading device. Operations scan the FLEX-MAT panel with the MAJOR app to access product information, simplifying re-ordering and inventory management. MAJOR can also program the chip during production with some customer-defined information to improve convenience. Users just need their smartphone to view the data. Prior to ID Enabled technology, operations required time-consuming gauge measuring — by hand — to order the properly-sized media. ID Enabled also enables operations to track orders with an electronic record instead of paperwork.

MEEKER
Meeker Equipment Co. Inc., Belleville, Pennsylvania, has launched the Freedom Air reverse-air baghouse. Hot air containing fine particles enters the baghouse’s tapered center plenum, evenly distributing air across all bags. Meeker uses variable fre quency drives (VFDs) on one to four stainless steel turrets atop the baghouse to move them faster or slower depending upon dust loading on the bags. The turrets pulse the bags in various configurations to allow even

flow of dust from the baghouse back to the drum or batch processes.
If a turret ever goes off line, the bag house can still operate. The operator simply takes the selected turret off-line and the plant continues. This is another unique fea ture of the Meeker Freedom baghouse.

MINDS
Minds Inc., Kelowna, British Columbia, offers the PlantManager multi-plant dashboard software.
PlantManager is designed to allow asphalt plant managers to gain a 30,000-foot lev el view of their company’s plants, all in one dashboard. Managers then spot issues at a glance and drill down into critical produc tion and job data.
The PlantManager software has opened windows into multiple plant processes, ac cording to the manufacturer, thanks to the use of aggregated data and Minds’ software development. The software allows all the Minds-equipped plants in a company’s arse nal to share relevant data, which gives management teams a one-stop shop for viewing plant production, configuring and generat ing reports, tracking plant health, and more. Managers can use this asphalt plant control system to look deeper into their individu al plants, where analog-style gauges make it easier than ever to track the temperature, energy consumption and mix rate of produc tion, according to the manufacturer.
The PlantManager asphalt plant software is available to managers who operate mul tiple sites that use Minds’ individual plant management systems, and can be used on tablets and PCs.
