VIBRATING SCREENS

Condition monitoring systems, like those offered by Haver & Boecker Niagara, include permanently affixed sensors for 24/7 monitoring and data collection for trends analysis.

Don’t compromise on vibrating screen health

Vibrating screens work at the heart of an operation; every tonne of material must be screened at least once before it is loaded into a truck for sale. And just like the human heart, the screens need to be kept strong and healthy to do their job well. By Wilm Schulz , Haver & Boecker Niagara service manager (exclusive to Capital Equipment News).

M aintenance crews have a lot to take care of. From vibrating screens and crushers to conveyors and load trucks, the list is a long one. It’s tough to be an expert on every piece of equipment. By partnering with a technical vibrating screen OEM that also specialises in equipment monitoring, operations can rely on a team that not only manufactured the equipment, but offers comprehensive diagnostic tools, product-specific knowledge and years of engineering experience. The result can be peace of mind, minimised downtime through faster problem solving, and lower repair costs down the line. There is a wide range of OEMs to choose from. While many have engineered reputable screening equipment, it’s important to consider the services they offer to take care of that equipment for the long run. One that has dedicated research and development focused on diagnostic tools, for example, will be that much further ahead in keeping that heart of the operation healthy. Vibration analysis & monitoring Vibration analysis is one such tool dedicated to measuring

the health of vibrating screens. These systems measure and transmit real-time vibration data such as acceleration, orbit, deviations and more. The data is transmitted while the machine is in operation via sensors that are placed at dedicated locations on the screen body. The information is recorded to software in a phone, tablet or computer, or to a cloud service where it can be viewed from multiple devices. In addition to analysing current machine performance, some systems also store historical data in order to predict the machine’s future performance and schedule maintenance accordingly. All of this data is used to fine- tune equipment for optimal performance and maximum output, as well as locate issues that could lead to larger repair costs or machine failure and unplanned downtime if not addressed. An OEM should perform a vibration analysis on any new vibrating screen before it even leaves the factory. This provides a baseline for how the machine should run. At each service visit, vibration analysis should be used to better understand the machine’s condition before any repairs are made. Once technicians make necessary
