The track-mounted GT205 multi-frequency screen features KPI-JCI and Astec Mobile Screens’ multi-frequency screen design, which blends the technology of conventional incline and high frequency screens to create a screening tool that increases fines separation more than any other in its class, according to the manufacturer.
Conventional incline screens function by applying a lower speed (900 to 950 rpm) and increased stroke (1/4 to 3/8 in. [.6 to .9 cm]) to the entire screen box to convey the material down the screen and maintain consistent bed depth. High frequency screens apply high speed vibration (3,600 to 4,200 rpm) directly to the screen media to allow for increased stratification and separation of material.
The GT205 multi-frequency screen combines the two screening theories to produce a one-of-a-kind vibration that creates a versatile screen prepared to tackle any application, according to the manufacturer.
“We know that coarser material requires more amplitude and less frequency, while finer material requires less amplitude and more frequency. By combining these theories, we can take advantage of the power of our high frequency screen, which offers the highest screen capacity in the market for fines removal, chip sizing, dry-manufactured sand and more,” said Stephen Whyte, product manager of KPI-JCI and Astec Mobile Screens.
“Our new GT205 multi-frequency screen allows producers to process finer materials with higher moisture content that no conventional screen could process, all while being operated at a lower angle than a high frequency screen.”
The GT205 multi-frequency screen is well-suited for applications including sand and gravel, top soil, slag, crushed stone, recycle, reclaiming and reducing waste and processing materials from 6 in. (15 cm) to 20 mesh. It is ideal for experienced producers seeking to reclaim material or reduce waste and improve their performance compared to conventional screens, Whyte said.
