Weir has designed its next generation of elliptical motion screens that are fully bolted and highly modular.
One of the main reasons a vibrating screen fails is high stresses on welded joints.
When a screen fails, it causes costly downtime for a quarry, cutting into profits and productivity.
That is why Weir has eliminated all welding from the main screen body on its new ENDURON Orbital range of vibrating screens.
Weir’s global product manager for vibrating equipment Corné Kleyn said the ENDURON Orbital vibrating screens are the next generation of circular motion and elliptical motion sand and aggregate screens.
“They are designed for modularity, ease of maintenance, and long service life,” he said.
“We have designed the screens with the widest operating window out of any screen, hereby eliminating failures associated with natural frequencies, which are often associated with vibrating screens.”
Designed for a wide range of feed material, the ENDURON Orbital screens operate in a variety of screening applications across sand and aggregate, construction and small tonnage mining operations.
The elliptical screens are built to deliver a combination of quality, superior performance and exceptional reliability when processing the most difficult materials.
The ENDURON Orbital E series screens accept feed sizes of up to 150mm. Their deck support structure allows them to switch between side-tension and modular panel decks without replacing the deck assemblies.
Kleyn said modularity and configurability have been considered throughout the entire design of the vibrating screen.
“We can accommodate both modular flat decks and side-tension crown deck
on the same deck structure,” he said.
“This allows for even more flexibility as operating conditions change.”
The all-bolted connections ensure ease of maintenance during the replacement of components. Carious parts can be individually replaced without needing to strip down the entire machine.
A premium rubber lining protects impact zones from wear in the toughest applications.
Kleyn said modularity is at the heart of the design of the vibrating screens.
“Decks, cross beams, exciters, they are all interchangeable within certain model sizes,” he said.
“With three single-shaft and three double-staff exciters, we are able to drive our full range of ENDURON vibrating screens.
“Bearings, seals, and shaft are all interchangeable between both the single and double-shaft exciter models. It further decreases the amount of spares our customers need to keep in stock.”
All of Weir’s ENDURON Orbital screens are EN 1009 compliant, meaning the operators can access the screening media in multiple-deck applications.
The digitally enabled modular exciters maximise bearing life thanks to their smart housing design and oil lubrication. Operators can measure exciter temperatures and vibration levels, then use that data to inform operational decisions.
Kleyn said the screens are competitive due to a design philosophy that takes advantage of global sourcing, parts commonality, and automated manufacturing processes.
As with all Weir products, the ENDURON Orbital screens are fully supported by the company’s service network, which offers support and expertise across the globe. •
