Trommel Screen Introduction
A trommel screen, also known as rotary screen, is an essential unit which is used mainly in the mineral and solid-waste processing industries. It consists of a perforated cylindrical drum which is normally elevated at an angle at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material smaller than the screen apertures passes through the screen, while the oversized material exits at the other end of the drum(via wikipedia).
Trommel Screen vs Vibrating Screen
Trommel screens are cheaper to produce than vibrating screens. They are vibration free which causes less noise than vibrating screens. Trommel screens are more mechanically robust than vibrating screens allowing it to last longer under mechanical stress.
However more material can be screened at once for a vibrating screen compared to a trommel screen. This is because only one part of the screen area of the trommel screen is utilised during the screening process whilst the entire screen is used for a vibrating screen. Trommel screens are also more susceptible to plugging and blinding, especially when different sized screen apertures are in series. Plugging is when material larger than the aperture may become stuck or wedged into the apertures and then may be forced through which is undesirable. Blinding is when wet material clump up and stick to the surface of the screen. The vibrations in the vibrating screens reduce the chance of plugging and blinding(via wikipedia).
