The aggregate processing plant features a custom-built chassis and six hydraulic run-on jacks that quickly level the screen, eliminating the need for cribbing. The jacks also ensure the chassis stays level during operation, minimizing equipment wear.

‘Portable plants should not only give producers the flexibility to move from one site to another or within a quarry, but they should also be fast and easy to set up,’ said Karen Thompson, president of Haver & Boecker Niagara’s North American and Australian operations. ‘We are committed to producing mobile screening plants that possess these qualities, with the same durability, longevity and minimal maintenance as stationary vibrating screens.’

According to Haver & Boecker Niagara, users can move and set up the machine in under 30min at most locations. The custom-built chassis includes a hydraulic system that positions the vibrating screen at an optimal 20o angle. The plant has three screen decks and features an advanced double-shaft design supported by four high-performance, double-spherical roller bearings.

The F-Class unit is suitable for demanding screening applications (eg scalping and classifying ores, mineral, stone, sand and gravel etc.) that require consistent, load-independent performance at constant g-force. Operators can also customize the portable set-up to include a crusher or conveyor for enhanced productivity. Additionally, Haver & Boecker Niagara can offer the Pulse vibration-analysis programme to monitor the ongoing health of the F-Class and other vibrating screens through real-time views, logged reports and data analysis.

Participating at Conexpo-Con/Agg for the sixth time, Keestrack will once again present their latest full-line programme of mobile processing equipment for the recycling and aggregates industry.

Highlighting the heavy range will be the Keestrack H6e full hybrid cone crusher for secondary and tertiary crushing. With a maximum feed size of 215mm and variable crushing chamber configurations and stroke settings, the specially adapted cone crusher, based on proven Sandvik technology, can processes up to 440 tonnes/h. The powerful e-motors for the crusher drive and plant hydraulics (220kW and 2 x 30kW respectively) and all other directly electric-driven components are powered by a detachable power unit including onboard diesel and generator (345kW/500kVa) or plug-in via mains or external genset. An optional three-deck post-screen module
(24.5 m2) with oversize recirculation ensures high-quality end products. With all options fitted, the machine weighs 68 tonnes (56 tonnes without three-deck screen).

Designed for hard stone and recycling applications, the diesel-hydraulic Keestrack B4 primary jaw crusher – also available as full hybrid electric plug-in version B4e – accepts a maximum feed size of 600mm and has a feed capacity of up to 400 tonnes/h.

MAJOR, a global manufacturer of high-performance screen media, will be using this year’s show to present their Flex-Mat high-vibration wire screens. The company’s technologically advanced wire screen media has been designed to deliver increased throughput by providing more open area than traditional panels.

According to MAJOR, Flex-Mat offers customers greater operational benefits with up to 40% more screen capacity than traditional woven wire and up to 50% more than traditional polyurethane/rubber panels, setting a new standard in performance for aggregates and mining producers. The product’s high-frequency movement helps make the media an active part of the screening process, improving efficiency compared with static media such as woven cloth and synthetic panels.

‘Quality is key to any operation, which is why we place a strong emphasis on it at MAJOR,’ said Bernard Betts, president of MAJOR. ‘We understand that no two operations are identical, which is why we configure each screening panel to precisely fit individualized requirements. That attention to detail is how we achieve what alternative media cannot — unrivalled throughput and superior end-product quality.’

The efficiency-enhancing characteristics of all Flex-Mat screening media products, including the modular panels, are created by bonding long-lasting OptimumWire with distinctive lime-green polyurethane strips rather than weaving them. This allows wires to vibrate independently from end to end under material contact. The high frequency of the wires, at 8,000 to 10,000 cycles per minute, adds to the vibration of the screen box (800–900 cycles per minute) which speeds up material separation and passing.

MAJOR say these features improve material throughput while virtually eliminating near-size pegging on the top decks and fine material blinding and clogging on the bottom decks, reducing the overall cost of production as well as providing up to five times longer wear life than traditional woven wire.

The Flex-Mat modular panels are available in three pattern options – D, S, and T series. The D series feature a standard square pattern for precise sizing, while the S series maximize open area to eliminate blinding and reduce fine contamination. The T series enhance screening for particles below 1.5mm and feature small openings to minimize blinding. The wire screen is secured through either grooved, step, or pin and leg panels.

MAJOR’s flagship Flex-Mat screen media panels are offered in either the patented OptimumWire or 304 stainless steel wire. They are also available in tensioned sections for use on crown decks.

At Conexpo-Con/Agg 2020, Metso will be showcasing their latest innovations and field-proven technologies for the aggregates industry, with a particular emphasis on the needs of small-to-mid-sized quarry operators and general contractors.

Previously launched at the 2017 show, the MX Multi-Action cone crushing technology has been well received by quarry operators around the world with close to 100 units sold in total globally. This year, Metso will feature the new MX3 crusher and a special Lokotrack mobile crushing plant equipped with an MX4 crusher.

Also on display will be the new Lokotrack ST4.10 mobile screen, a high-capacity screening plant for quarrying that further adds to Metso’s range of hybrid equipment. Other key offerings at the show will include Metso’s new lightweight truck body solution, which is available for all major off-highway truck models used in quarrying and mining operations.

In addition, with recycled aggregates becoming more acceptable in many regions, Metso will be showcasing their latest solutions in recycling and demolition, including their new, purpose-designed Nordtrack range, which includes track-mounted crushers and screens as well as track- and wheel-mounted stacker conveyors for recycling, demolition and small quarries.

At this year’s show, Philippi-Hagenbuch Inc. (PHIL), specialists in off-highway truck customization, will be showcasing a new version of their Autogate Tailgate specifically for off-highway trucks that require a 100% positive seal. The latest design can be paired with PHIL’s proprietary fluidic seal material to provide a water-tight seal that contains liquid materials within an off-highway truck body or roll-off container when environmental regulations make even slight spillage undesirable.

The Positive Seal Autogate Tailgate has been designed for any size off-highway truck and, when paired with PHIL’s simple and robust outrigger, its traditional scissors-style mechanism is said to provide an industry-leading maximum opening clearance at full dump. In the closed position, the new design locks into place and will not open under normal conditions without the body or container entering the ‘dump’ mode.

The Autogate Tailgate builds up the rearmost portion of the truck body to create a cohesive flange from which the tailgate compresses. Two hooks on either side of the base of the flange intercept a corresponding tag on the tailgate, allowing the tailgate to pivot inward as the sidearm and over-centre locking mechanism compressively locks the rear tailgate into place.

As with PHIL’s entire line of Autogate Tailgates, a three-year warranty is standard when installed with the company’s ‘installation supervision assistance’ scheme or at its Peoria facility, in Illinois. Optional body seals, fluidic seals and cushion pads are available to further customize PHIL’s Autogate Tailgates for unique applications.

When capacity is a concern, PHIL’s Positive Seal Autogate Tailgate can be built up for sideboards. These are available in 1in increments from 6in to 40in in height and provide a unified body height whilst increasing the volumetric capacity of the truck body, helping operators achieve optimal loads.

Making their ninth appearance at the Conexpo-Con/Agg show, Northern Ireland-based Rapid International will be exhibiting their Trakmix mobile continuous mixing plant, which offers an entirely self-contained design mounted on tracks, including an on-board genset, for fast, mobile flexibility.
