The performance of vibrating screens used by mining and aggregate companies can be tested and optimised using a new vibration analysis service program from mineral processing technology provider Haver Australia.
Developed by Haver Australia’s Canadian sister company Haver & Boecker (formerly WS Tyler), the Pulse system consists of sensors attached to key areas on the screening machine which sends 24 channels of data wirelessly to an industrial-grade tablet computer.
“The Orbit Report provides a visual of orbit and wave form, as well as data about acceleration, stroke, speed and phase angle,” Haver says. “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,” the company adds.
The screen shows real-time data which can also be stored in a database for an historical overview of the machine. The information can be downloaded online in two report formats including recommendations for improvement.
The system is designed to be easy to operate and to withstand harsh conditions in the environments where screening takes place.
“We know that Pulse has the potential to significantly impact the efficiency and profitability of our mineral processing customers as well as others in the processing chain,” Haver Australia technical manager Dominik Vennewald says.
“”hanging screen media products, unbalanced machines, and machine damage that is undetectable to the eye are some of the key contributing factors to machine wear and damage and inefficient operations,” he says. “By partnering with our customers through the Pulse service program, we can regularly monitoring the health of the machine and identify any problems early on.
“The program can significantly extend service intervals and improve performance,” Vennewald says. “Ultimately, this minimises downtime and maximises productivity and profits.”
