Equipment maker says Niagara F-Class portable plant is designed for easy screen change-out.

Haver & Boecker Niagara, Germany-based Haver & Boecker’s new mineral processing brand, is now offering the Niagara F-Class Portable Plant, which was on display at ConExpo-Con/Agg in Las Vegas in arch. The circular motion inclined vibrating screen has been designed to allow operations to increase production by 25 percent while making screen media change-outs easier, says the firm.

“We design technology with the success of our customers in mind,” says Karen Thompson, president of Haver & Boecker Niagara’s North America and Australia operations. “The F-Class Portable Plant is putting more money into our customers’ pockets while making their jobs easier.”

A circular motion inclined vibrating screen uses gravity to help move material down the screen deck, reducing pegging as well as energy and horsepower requirements, says the firm. On a 20-degree incline and at a 70 to 75 feet per minute travel rate, an inclined screen will deliver up to 25 percent more capacity than a linear-stroke horizontal machine, according to Haver & Boecker Niagara.

The company cites Alberta, Canada-based trucking and heavy construction company Pidherney’s as an operator who has benefited from using the machine. “The F-Class Portable Plant exceeds expectations,” says Merv Pidherney, the firm’s owner. “I looked at other plants, and they just didn’t meet our needs. I wanted a trouble-free plant and I got it.”

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, says Haver & Boecker.

The vibrating model also is billed as ideal for tough applications, featuring four-bearing technology. The F-Class Portable Plant can be customized to include a crusher, conveyors or other components.

Global equipment provider says X900 can process up to 500 tons per day, but is portable.

United Kingdom-based CDE, which has its United States headquarters in Cleburne, Texas, has unveiled its 500 tons-per-hour (tph) Combo X900 at ConExpo-Con/Agg in Las Vegas in mid-March.

The company calls the X900 “the latest in CDE’s range of revolutionary Combo all-in-one wet processing and water management solutions.” With its 500 tph capacity, the new Combo X900 is the largest in the CDE series to date.

“With our new ComboTM X900, we’ve doubled its capacity and created a next-gen solution for materials processors across North America and Latin America,” says Kevin Vallelly, director of engineering at CDE.

The company says its wet processing systems can be customized “to reuse 80 to 100 percent of materials from construction, demolition and excavation waste.” CDE says it has installed some 2,000 wet processing systems globally and has “developed best in class solutions for recycling operations.”

CDE says its systems are “pre-wired, factory built and tested to get [customers] up and running in the shortest time possible.” It also says its AquaCycle technology “ensures up to 95 percent of process water is recycled for immediate re-use in the system.”

Says Vallelly, “Traditional washing systems would typically consume up to 15 times more water than that required for the Combo X900.” He adds, “The Combo X900 enables materials processors to wash more than 500 tph with only 800 gallons per minute, about the same amount of water that would be required to wash a truck.”

Calling it a plug-and-play system, CDE says the Combo X900 can be ready to process material within five days as a standalone plant or as part of a larger system.

Portland Cement Association economist Ed Sullivan outlines potential scenarios at ConExpo presentations.

Preparing an economic forecast in early March 2020 proved a fruitless task, according to Ed Sullivan, a vice president and the chief economist of the Skokie, Illinois-based Portland Cement Association. Sullivan presented recaps of his 2020 and 2021 forecast at a press conference at the ConExpo-ConAgg event in Las Vegas in mid-March, and at the annual meeting of the Construction and Demolition Recycling Association (CDRA), also in Las Vegas.

In the 10 days leading up to ConExpo, said Sullivan: several candidates dropped out of the presidential election; oil prices plummeted; the stock market in the United States and other nations lost tremendous value; the U.S. joined Asia and Europe with growing coronavirus cases and reactions; and the Federal Reserve Bank in the U.S. reduced interest rates to try to stave off coronavirus impacts. “A piece of cake,” joked Sullivan regarding creating a forecast.

The presentation and forecast devised by Sullivan thus included three scenarios for how the coronavirus could impact the U.S. economy, ranging from the shortest-term impact to a longer, more severe set of effects.

He selected the least damaging scenario as the most likely as of Wednesday, March 11, but acknowledged conditions were changing rapidly. In his preferred scenario, Sullivan sees six-to-eight weeks of economic disruptions, in particular to travel and leisure time discretionary spending. In that scenario, “panic and fear” in the U.S. would be relatively contained to a short time frame and the leisure sector, and a combination of lower interest rates and oil prices would help spur a rebound by the third quarter of 2020.

Sullivan said that if virus concerns remain beyond April and May, the prolonged fear would more deeply hit the American household consumer, “who accounts for two out of every three dollars” spent in the U.S. economy. Preliminary polling has already shown, said Sullivan, that when coronavirus cases are found geographically close to people, they can quickly change their behavior.

Underlying the coronavirus concerns, said Sullivan, is the notion that the U.S. economy is “due” for a recession after more than 10 years of steady growth. Dispelling that notion, said Sullivan, is the case of Australia, where economic growth has been ongoing for 27 years.

On the other hand, Sullivan said there are factors pointing to the idea that the U.S. is “in the late stages” of an economic upcycle. Even though employment figures are good, some 50 percent of metropolitan areas are exhibiting growth rates that show signs of being late stage. When that figure hits 60 percent, said Sullivan, that means a recession hits 12 to 18 months later.

The U.S. economy has lost some of its “zip and vigor,” said Sullivan, and the extent of coronavirus reactions will play a role in determining whether the U.S. can maintain economic growth through the turmoil, or if it experiences some negative growth quarters.

On the infrastructure and construction front, Sullivan says some 30 states have done what the federal government refuses to do—raise their per-gallon gasoline tax. This has helped some states boost their highway and transportation spending, raising the amounts of cement and concrete going into public works.

The association is considering alternative dates and venues for its convention, which was scheduled to take place April 27-30 in Las Vegas.

The Institute of Scrap Recycling Industries (ISRI), Washington, plans to postpone the ISRI Annual Convention & Exposition, ISRI2020, which was originally scheduled to take place April 27-30 at the Mandalay Bay Resort and Casino in Las Vegas.

“ISRI has been monitoring the spread of COVID-19 and its impacts on national and world events for nearly two months with one key factor in mind: the health and safety of our members, meeting attendees, exhibitors and staff,” says Brian Shine, ISRI chairman and president of Manitoba Corp. in Lancaster, New York. “Given that the World Health Organization officially deemed this a pandemic, and in light of the many states declaring an emergency along with associated closures and curtailments of normal daily life, it is impossible for ISRI to hold the convention as planned. 

“Therefore, for the safety of all involved, we cannot move forward with the ISRI2020 convention in April of this year,” he continues.

Shine says the association and convention team is in the process of reviewing options for alternative dates and venues as well as different methods of information delivery. He adds that more information on the impact of this cancelation will be sent to preregistered attendees and exhibitors in the coming days and weeks. 

“Thank you to all of you who have communicated with us to express your support and thoughts,” Shine concludes. “Let’s continue to work together through this pandemic and into even greater success in the future.”

The Inventhor Type 6 and the Methor are new to the company’s slow-speed shredder line.

Doppstadt, Velbert, Germany, plans to launch two new models to its slow-speed shredder line at IFAT 2020, which takes place in Munich. Both models, the Inventhor Type 6 and Methor, are in line with they company’s “Smart Solutions” concept: mobile, modular machines that can be used cost effectively and flexibly in a variety of areas of application, the company reports in a news release on its new shredder models.

The Inventhor Type 6, the successor to the DW 3060, is ready to “set new standards of use” in the recycling industry, according to Doppstadt. The entire machine concept has been optimized for economic efficiency, ease of use, good accessibility and minimized downtime. 

The VarioDirect Drive forms the core technology that combines high throughput, low fuel consumption and optimum startup performance even with difficult shredding jobs, Doppstadt reports. The shredder can handle a wide range of applications in the area of preshredding as a result of its configurable shredding system with easy-to-replace teeth that are available in size M and L, including limiters. 

According to Doppstadt, placing Doppstadt’s Selector 800 with SWS 800 spiral shaft screening deck, the company’s separation solution, directly in line after the Inventhor Type 6 results in an ideal machine combination to allow for the inline generation of a finished product. Also, presettable material programs support the operation of the Inventhor Type 6. 

Quality for small volume flows

Doppstadt reports that its Methor leverages the advantages of the company’s high-performance technology for smaller volume flows, monobatches or special materials, and the machine is geared toward maximum flexibility. The Methor shredding system can be switched over within 60 minutes. It is ideal for jobs with smaller volumes of materials or frequently changing tasks. 

Similar to the Inventhor Type 6, this shredder can be optimally combined as part of more complex systems with other Smart Solutions from Doppstadt, such as the Selector 400 with the SWS 400 spiral shaft screening deck. 

The Methor’s shredding shaft ensures high process reliability and processes material directly in the conveying direction of the rear belt, Doppstadt reports. With the Methor, the Hydraulic Direct Drive provides the best regulated output in conjunction with the unique load-controlled material feed by a tipping hopper. The company reports that this ensures the machine always works within the optimum utilization of the shredding unit capacity. 

The drive system also reacts quickly to blockages so that the machine protects itself. The internal components are easy to access and optimally cooled as a result of large ventilation openings. 

At the time of the product launch, the machine is powered using diesel engine technology, but the line will be expanded to include an electric drive option. In addition, the Methor is available as a stationary version as well as a carrier version for use with hooklift or on a track-mounted chassis. Also, the Methor can be connected via WiFi to any smartphone, laptop or tablet that is internet-enabled and has a browser installed regardless of the operating system.
