HAVER Australia is casting a medical eye on its screening machines with the introduction of the Pulse service for vibration analysis, as part of predictive maintenance.

Haver Australia has introduced the Pulse service for better maintenance of its screening machines.

Developed by its Canadian sister company Haver and Boecker (formerly WS Tyler), Pulse monitors the health of vibrating screens to help users up performance and equipment durability through predictive maintenance.

The system consists of a tablet computer that uses wireless technology to connect with sensors attached to key areas on the screening machine. The sensors send 24 channels of data to the tablet to illustrate in real-time the machine’s orbit, acceleration, deviations and other performance criteria.

Haver Australia technical manager Dominik Vennewald said Pulse had the potential to impact the efficiency and profitability of the mineral processing chain.

“Changing 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 said.

“By partnering with our customers through the Pulse service program, we can regularly monitor the health of the machine and identify any problems early on.

“The program can significantly extend service intervals and improve performance. Ultimately, this minimises downtime and maximises productivity and profits.”

In addition, information from the sensors can be electronically stored in a database and downloaded online in two report formats that include recommendations for improvement.

The orbit report provides a visual of orbit and wave form, as well as data about acceleration, stroke, speed and phase angle. The software also processes Fast Fourier transformation plots for values for each measuring points in three channels of data.

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.

If improvements are required, a Haver technician will get a service call to examine the machine.
