Geheimrezept hoher Druck und wenig Wasser: Der Hydro-Clean reinigt Körnungen von Schad- und Störstoffen bei geringem Ressourceneinsatz.

Die Hydro-Clean Waschanlage HC aus dem Programm von Haver & Boecker Niagara befreit in effektiver Weise Nutzkorn von Schad- und Störstoffen. Dabei soll der Wasserbedarf im Vergleich zu traditionellen Waschsystemen um bis zu 75 % niedriger liegen bei ebenfalls um bis zu 15 % geringeren Energiekosten. Dieser Spareffekt ist der kompakten Baugröße und dem geringeren Gewicht gegenüber traditionellen Waschsystemen, die zudem eine größere Aufstellfläche haben und mehr Ausrüstung benötigen, zu verdanken. Das wartungsfreundliche Design ermöglicht im Bedarfsfall den einfachen Austausch der wenigen Standardkomponenten, wobei der HC laut Hersteller wenig verschleißanfällig sein soll.

Zur Reinigung von Aufgabematerialien bis zu einer Größe von 150 mm in einer vertikalen Trommel sprühen Hydro-Clean-Hochdruckdüsen Wasser mit Drücken bis zu 140 bar bei einer Drehzahl von 90 UpM auf das Material. Das Waschsystem entfernt auf diese Weise Schlamm- und Lehmpartikel bis zu 63 Mikron aus Mineralgemischen.

Die Waschanlage ist in vier Modellgrößen erhältlich, die 18 bis 400 t Material pro Stunde aufbereiten, je nach Typ und Anwendung. Der Wasserverbrauch reicht dabei je nach Anwendung und Modellgröße von 102 bis 798 l/min.

Das System funktioniert folgendermaßen: Verunreinigtes Material wird über einen Trichter in die vertikale Trommel des Hydro-Clean aufgegeben, woraufhin die oben montierten Hochdruckdüsen rotieren und das Material mit Wasser besprühen. Die Turbulenzen in der Trommel erzeugen zusätzliche Scheuer- und Schleifkräfte, die den Reinigungsprozess verstärken, während das Material den Trommelzylinder passiert. Am Ende des Reinigungsprozesses wird die Aufgabe über einen Abzugsförderer ausgeleitet, der zu einem Waschsieb führt. Dieses ist für eine Nachwäsche zuständig, während es gleichzeitig das Material fraktioniert.

The master system allows customers to get the most production and profitability out of their natural mineral deposit. The system provides increased flexibility for primary crushing stages, especially with non-homogeneous natural deposits. For high quality natural deposits, the operations can use the master system to feed extracted material completely to the production. The system can screen stony soil off to a second vibrating screen for moderate natural material deposits. The system can be configured to completely remove stony soil from difficult natural material deposits.

Both systems work with the Haver & Boecker Niagara N-Class vibrating screen. The screen is perfect for scalping thanks to its smooth operation and heavy-duty design making it capable of screening as much as 5,000 tons per hour. 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.

Haver & Boecker Niagara primary crushing plant systems feature rugged steel construction and a robust design incorporating a durable, optimum flow, low wear and maintenance friendly chute system and integrated custom conveyor technology. Accessibility is easy thanks to engineered work platforms, walkways and stairway systems. Integrated plant control systems and data management ensure intuitive operation.

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
