WEDGE WIRE TROMMEL SCREENS | CYLINDRICAL DRUMS
Looped wedge wire trommel screens from Screen Systems
Wedge wire trommel screens, also known as rotary screens, are mechanical screening machines used to separate materials. Mainly, these are used in the mineral and solid-waste processing industries. In addition, they are often used to remove fines from a given waste stream. The trommel consists of a wedge wire cylindrical drum that is normally elevated at an angle at the feed end. Screen Systems looped wedge wire is an extremely robust and durable screening method product.
How does a recycling wedge wire trommel screen work?
Material is fed into the trommel drum and is lifted up by the rotation and aerated as it falls back down. Then, this action is repeated with each revolution along the length of the drum. As a result, the smaller segments pass through the screen openings. Also, the larger fractions tumbles towards its eventual exit at the rear of the drum.
A trommel drum cylinder is used to separate materials by size. For example, they are sometimes used for separating biodegradable fraction of mixed urban waste. Also, for separating different sizes of crushed stone. In addition, 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. As a result, this allows the contractor to resell their waste, instead of incurring the cost of sending it for disposal.
Wedge wire and looped wedge wire cylindrical drums are often used for wash plant applications. For example, coal mining, mineral extraction plants, fibreglass processing operations. Also, food washing factories and many more.
