TROMMELS / TROMMEL SCREENS 

A trommel screen (also known as a rotary screen / screening drum / trommels), is a mechanical screening machine used to separate materials, mainly in the mineral and solid-waste processing industries, often used to remove fines from a given waste stream. It consists of a wedge wire cylindrical drum that is normally elevated at an angle at the feed end.

How does a Recycling Trommel Screen work?

Material is fed into the trommel drum and is lifted up by the rotation and aerated as it falls back down. This action is repeated with each revolution along the length of the drum. The smaller segments pass through the screen openings while the larger fractions tumbles towards its eventual exit at the rear of the trommel drum.

A trommel drum cylinder is basically used to separate materials by size, an example of this is they are sometimes used for separating biodegradable fraction of mixed urban waste or separating different sizes of crushed stone. Contractors may screen their site debris into two segments; a saleable topsoil for farms, nurseries and site-work, as well as rock cleaning for aggregates or landscaping work. This allows the contractor to resell their waste, instead of incurring the cost of sending it for disposal.
