Screening News - Preventing pressure screen failure

Why is screen fit so important?

A primary cause for cylinder breakage is wear in the base of the screen housing. The interface design of the housing and cylinder make a “fit”, and maintaining that fit is critical for keeping the cylinder stationary and operating properly.

A loose fit can be indicated by vibration and cylinder movement, leading to damage that can show itself in a number of ways:

• Wear in the housing fit area
• Increased vibration of the screen
• Additional stress on the top fit where the cylinder is bolted and eventual bolt breakage
• Movement of the cylinder causing inefficient surface cleaning – leading to poor debris removal
• Additional stress on the cylinder leading to breakage
• Loss of efficiency in the filtration process

A regular screen inspection is the most critical maintenance step to prevent pressure screen failure. Inspection frequency will depend on the screening process and typical wear tendencies.
