What is the design of a trommel screen? Trommels are rotating screens within a cylindrical tube. Trommels are open on both ends and may have a small incline so the material can move through, paired with the rotating screen. The screens can be made of a plate with holes in it, a wireframe, or other materials depending on materials that need sorting.Web

TROMMEL. SCREENS. Our trommel screens are highly efficient in the separation and processing of wood chips, top soil, compost, light demolition waste, domestic waste and aggregates. Their rotating drums roll larger pieces of material to allow all fines to flow down and through the trommel screen plates.Web

Trommel screen, or rotary screen, is a kind of mechanical screening machine which is widely used in the separation operation. It controls the material separation by the particle size, and the separation precision is high. The cylinder of the trommel screen is generally divided into several sections, depending on the specific situation.Web

The trommel design implication is that we need to stop the feed landing half way down the trommel screen as this reduces trommel efficiency and causes high wear to the screen media. "In order to combat this we have designed what we call a baffle plate placed at the feed end of the trommel that forces the feed down onto the trommel surface to ...Web

To begin choosing the right size trommel screen for your operation, Bonhorst recommends looking at the screen size. "Most operations are looking for screens between a 1/8 inch to 3 inches (.3 cm to 7.6 cm), and production rates can vary greatly depending on size selected," he said. "Smaller screens produce a more fine material for reselling.Web

A trommel, also called a rotary screen, is used to separate materials. As the barrel spins, smaller materials are sifted through the screen while the bigger stuff stays in the middle.

However, the design is primarily based on heuristics. Therefore, design rules are often used instead of governing equations in the design of trommel screens. When designing a trommel screen, the main factors that affect sieving efficiency and production rate are drum rotation speed, feed particle mass flow rate, drum size, and trommel screen tilt.Web
