Abstract
A modular multi-disc assembly for use in material separation screens and a method of application to those screens are provided. The modular multi-disc assembly includes an inner securing hub that clamps onto the drive shaft of a material separation screen. The modular multi-disc assembly further includes an outer multi-disc module split into halves with each half mounting separately onto the inner securing hub. Multiple discs can be replaced at one time as opposed to replacing each individual disc in a typical screen. The inner securing hub spaces the outer multi-disc module away from the drive shaft so that the primary wear concern reduces to the resilient discs on the outer multi-disc module, allowing for multiple outer multi-disc module replacements before needing to replace the inner securing hub.
