Haver & Boecker Niagara N-Class Scalper Excels in Heavy-Duty Applications

Haver & Boecker Niagara offers the rugged, efficiency-enhancing N-Class vibrating screen to optimize crushing plants and screening operations through its ability to screen as much as 5,000 tons per hour. The Niagara N-Class is ideal for tough jobs, such as scalping and classifying ores, minerals, stones, sand and gravel in aggregates and mining applications. Haver & Boecker Niagara builds the equipment with an advanced four-bearing design that minimizes structural vibration and maintains constant g-force even through fluctuating material feed rates.

“The Niagara N-Class is a one of a kind machine with the ability to productively accomplish screening tasks other vibrating screens have difficulty with,” said Peter Grotjohann, managing director of the German facility. “The machine offers our customers an ideal solution for improving crushing plant efficiency and classifying coarse materials, therefore improving profits.”

Haver & Boecker Niagara’s N-Class offers one to threescreen decks and features an advanced single-eccentric shaft design that’s supported by four high-performance, double-spherical roller bearings. It is dynamically balanced to minimize dynamic loads transferred into the structure and allows multiple screens to be placed side by side in the same building. The N-Class maximizes screening efficiency and virtually eliminates blinding and pegging by providing a consistent g-force in all operational modes regardless of load consistency. A heavy-duty body design handles heavy loads in applications with extreme material sizes up to 2 x 1 x 1 meter. The screens offer a self-cleaning action to minimize common problems encountered with traditional grizzly feeders.

The N-Class is ideal for reducing loads and energy demands for a crushing plant by providing more consistently-sized material to improve crushing efficiency. The use of the vibrating screen in the process before the crusher increases the crusher capacity and maximizes the quality of the crushed product.

Each N-Class comes equipped with Haver & Boecker’s signature Ty-Rail System, which cuts media replacement time by about 50 percent by simplifying the process.

Haver & Boecker Niagara builds the N-Class for quick and easy re-balancing. It includes long-life bearings and a maintenance-friendly, modular machine design. The vibrating screen is equipped with buffers between the screen box and support frame for improved process reliability.

It is recommended to equip the machine with Haver & Boecker Niagara’s patented crossbeam abrasion protection system, Snap-Guard®. Snap-Guard is made from polyurethane and protects crossbeams from harsh materials, extending maintenance intervals, reducing operating costs and increasing profits.

Haver & Boecker Features Ty-Rail™, an Industry-Changing Tension Rail System for Vibrating Screens

Haver & Boecker features the Ty-Rail™ quick-tensioning system. The patented Ty-Rail 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. The Ty-Rail system provides a fast return on investment, and cuts screen change-out time in half.

Haver & Boecker will feature Ty-Rail in Hall B2, Booth 149 at bauma 2019 in Munich.

“As a whole, Haver & Boecker is committed to innovation that’s focused on improving efficiency,” said Florian Festge, Haver & Boecker managing director. “Our engineers’ invention of the Ty-Rail system solves the long-time problem of lost parts and difficult, time-consuming screen panel change-outs. Without a doubt, once implemented, our customers will see increased uptime and, as a result, profits.”

Each Ty-Rail package includes two tension rails, eight angle boxes and eight bolts; all the hardware required to change one screen section. Once installed, each rail becomes a singular, removable piece since the bolts remain attached to the rail, and the angle boxes remain attached to the vibrating screen. To remove the tension rails, an operator simply loosens the bolts on each, shifts the angle boxes up, and lifts the rail and bolts out as one piece. This reduces screen media change-out times by about 50 percent. Additionally, the innovation can take the task of changing tensioned screen media panels from two people down to one.

The system is designed specifically for Haver & Boecker’s vibrating screens.

Underground processing plant for fluorspar

The opening up of a new mine in Germany’s Erzgebirge (Ore Mountains) in late 2013 marked a milestone for German mining, continuing the tradition in this region, following decades of stasis. The reasons for the extraction of fluorspar and baryte are closely tied to steadily rising raw material prices on the world market. The operator, the Erzgebirgische Fluss- und Schwerspatwerke, chose HAVER NIAGARA GmbH when it came to designing and installing an underground processing plant for the mine in the Erzgebirge. HAVER NIAGARA GmbH took on the challenge to set up a flexible and economically viable processing plant (Fig. 1). Despite the limited space and the high requirements to be met by the processing plant, a tailored plant was designed (Fig. 2) that fulfils the high expectations of the operator to full satisfaction.

The processing plant roughly consists of two independent production lines, which were installed in two parallel underground caverns. In the first process stage, the blasted raw material is removed from the feed bin by means of reciprocating feeders and fed to a NIAGARA scalper (Fig. 3). This reduces the load to be processed in the downstream jaw crusher. The material from the primary crusher is conveyed on a troughed belt conveyor to a NIAGARA screen, which as well as screening off the ultrafine material, splits the material into two sub-streams to feed an X-ray sorting plant. This sorter separates the raw spar from the “dead rock” on the basis of the atomic density. The raw spar obtained in this way is crushed in a cone crusher to the necessary finished grain. The crusher discharge is sent via a downstream NIAGARA screen to a loading silo, there the raw spar is loaded onto road trucks.

From there, the material is conveyed to the processing plant above ground, where it is ground and enriched in a flotation plant and then separated into the main components baryte and fluorite. After drying, two high-grade raw materials are produced, which are then sold.

Over the next years, HAVER NIAGARA GmbH will be on hand providing services for our german customer to keep the complete plant at its best both economically and ecologically.

Haver & Boecker offers the Pulse Vibration Analysis Service Program

Haver & Boecker  Niagara features its Pulse vibration analysis service program. This innovation in vibration analysis gives mining and aggregate customers a means to optimum vibrating screen performance.

Haver & Boecker will feature Pulse in Hall B2, Booth 149 at bauma 2019 in Munich.

Pulse is designed specifically to monitor the health of vibrating screens to ensure optimum screening performance and equipment durability. Understanding that small imbalances can lead to substantial and expensive problems, the program detects irregularities that could translate into diminished performance, decreased efficiency and increased operating costs for the vibrating screen. The reporting and historical tracking of the machine’s performance gives customers the information needed to minimize downtime and maximize productivity and profits.

The program was developed to be easy to operate. Components were specifically chosen and engineered for the harsh environments where screening takes place.

“Pulse has the potential to significantly impact our mineral processing customers as well as others in the processing chain,” said Florian Festge, Haver & Boecker managing director. “Customers that utilize the Pulse system have the tools they need to optimize screening efficiency on a daily basis. This helps improve their operation’s profitability through minimized downtime and lower maintenance costs.”

Pulse gives customers the hardware and software required to instantly record vibrations on their machine. That data is then transmitted to Haver & Boecker where the engineering team analyzes it. The team then issues a report back to the customer including an analysis of the machine’s performance and recommendations for improvement.

If the results are good, the customer has reassurance that the machine is healthy. If the results require a Haver technician to examine the machine in person, a service call is scheduled.

The Pulse system uses an industrial-grade tablet computer that connects wirelessly with eight tri-axial sensors. The sensors attach to key places on the equipment and send up to 24 channels of data to the tablet, which displays a real-time view of the machine’s orbit, acceleration, deviations and more.

Beyond the real-time view on the screen, all of the information from the sensors is electronically stored in the database for an easily-accessible historical overview of the machine. The information can be downloaded online in two report formats. The Orbit Report provides a visual of orbit and wave form, as well as data about acceleration, stroke, speed and phase angle. Fast Fourier transformation, or FFT, plots are processed by the software for values for three channels of data for each measuring point. The Tuning Report extrapolates deviations between measurement points while providing recommendations on balance, acceleration, stroke and speed. It provides feed and discharge analysis as well as diagonal measurements.

Hooked Engineered Screen Media as Alternative to Costly Deck Conversions

Haver & Boecker Niagara, a leading equipment manufacturer and solutions provider in aggregates and mining applications, offers its Tyler brand of hooked engineered screen media as a solution to the problem of expensive deck conversions. Tensioned screen media can be used on a cambered deck, eliminating the need for a deck conversion when switching from woven wire to polyurethane screen media. The media includes products such as Ty-Max and Ty-Wire.

Haver & Boecker will feature Tyler engineered screen media in Hall B2, Booth 149 at bauma 2019 in Munich.

Hooked screen media allows operations to easily switch from woven wire to modular polyurethane products without the expense of a deck conversion. Retrofitting a machine from a cambered deck to a flat deck can cost as much as $15,000 per deck. Tyler’s tensioned screen media is used on a cambered deck to eliminate the need for that conversion. This also allows operators to test the media on a vibrating screen with no additional cost or commitment.

Another benefit is that Ty-Max and Ty-Wire can be blended with woven wire or self-cleaning screens on cambered decks. In many applications, operators are looking for more wear life on the feed end of the screen. This can be accomplished by installing a section of Ty-Max at the feed end. Ty-Wire can be used in the middle of the deck, for example, where basic screening takes place to give operators the ideal combination of wear life and open area. Using woven wire or self-cleaning screens at the discharge end will provide maximum open area at the end of the deck.

The screen media is manufactured out of Haver & Boecker’s signature blend of polyurethane. It’s made in one of the only facilities that blends its own material, which is critical for quality control. Chemists developed the media to offer the best combination of open area and wear life for both wet and dry applications. Engineered screen media is poured open cast, resulting in 1.5 to 2 times longer wear life than injection-molded products sold at comparable prices. In addition, open cast polyurethane permanently hardens when cured to maintain its chemical properties, so it resists wear and tear. Injection-molded screens can soften when the temperature rises during screening, resulting in shorter wear life.

Haver & Boecker manufactures a variety of engineered screen media options to suit different operations’ applications, taking into consideration top sizes and opening requirements. Operators looking for high durability and strength choose Ty-Max, which Haver & Boecker reinforces with an internal wire grid as thick as 9.5 millimeters (3/8 inch). Ty-Wire combines woven wire with an engineered composite to achieve open area closer to wire cloth but with four to six times longer wear life. Ty-Wire weighs less than woven wire, making it safer to handle and easier to install.

Haver & Boecker also offers Ty-Deck modular panels, available in multiple configurations for flat deck setups. Ty-Deck’s lightweight design eases installation and sectional deck replacements
