84 • ROCK products • May 2015 www.rockproducts.com EQUIPMENT & TECHNOLOGY SCREENING & SIZING nership with SKF gave them in helping to solve this critical bearing and lubri- cation issue," Fuller said. "The F-Class vibrating screen featuring the upgraded SKF Explorer bearings are tested and proven to offer nearly double the service life in poor lubrica- tion conditions and twice the service life in contaminated conditions," said Keith Meyers, global industry manager, mining mineral processing and cement, SKF. "The operation of the F-Class with upgraded SKF Explorer bearings at the Arizona copper mine match these results." W.S. Tyler – now using its parent company's name, Haver & Boecker – introduced the Pulse vibration analysis program. This innovation in vibration analysis gives mining and aggre- gate customers a means to optimum vibrating screen perfor- mance. Haver & Boecker's team of engineers, led by Dieter Takev, designed Pulse specifically to monitor the health of vibrat- ing screens to ensure optimum screening performance and equipment durability. Understanding that small imbalanc- es can lead to substantial and expensive problems, Pulse 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. Pulse was developed to be easy to operate. Components were specifically chosen and engineered for the harsh envi- ronments where screening takes place. The Pulse program gives customers the hardware and software required to instantly record vibrations on their machine. That data is then transmitted to Haver & Boecker, where it is analyzed by the engineering team. 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 reas- surance that the machine is healthy. If the results require a technician to examine the machine in person, a service call is scheduled. The system consists of an industrial-grade tablet computer that uses wireless technology to connect with eight tri-axial sensors. The sensors are attached in key places to the equip- ment and send 24 channels of data to immediately illustrate the machine's orbit, acceleration, deviations and more. Beyond the real-time view on the screen, all of the informa- tion 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 pro- cessed by the software for values for three channels of data for each measuring point. The Tuning Report extrapolates deviations between measurement points while provid- ing recommendations on balance, acceleration, stroke and speed. It provides feed and discharge analysis as well as diagonal measurements. "We know that Pulse has the potential to significant- ly impact the efficiency and profitability of our mineral processing customers as well as others in the processing chain," said Karen Thompson, president of Haver & Boeck- er's W.S. Tyler operations. "Changing screen media prod- ucts, unbalanced machines, and machine damage that is undetectable to the eye are some of the key contributing factors to machine wear and damage as well as inefficient operations. By partnering with our customers through the Pulse service program, together we are regularly monitor- ing the health of the machine and identifying any problems early on. Pulse can significantly extend service intervals, improve performance and ultimately save our customers a lot of time and money." Pulse was developed specifically for vibrating screens. The measurement equipment DAViS MD is based on hard- ware and software that was developed and perfected by Haver & Boecker over years of research and develop- ment. DAViS Machine Diagnostics is now available for any age, model or brand of vibrating screen equipment. Haver & Boecker, www.wstyler.ca Haver & Boecker Pulse Vibration Analysis Service As Seen At:
