The SI screens feature a robust drive mechanism and oversized bearings to handle large tonnages and a wide variety of applications. Utilised as wet or dry screens, the units have adjustable stroke and speed combinations to fit a variety of applications and are available in 2 or 3 deck configurations. They are fitted with woven wire media but Terex MPS says they can be converted into modular media with polyurethane, rubber media or steel plate without any cutting or welding.
“The SI screens are intelligently engineered to provide maximum value and long life,” said Edwin Sauser, Terex MPS product manager. "The screens are versatile, reliable and have features designed for easy maintenance, such as large spacing between decks, which also allow for quick media changes."
The screens also have the option of operating with grease or oil lubrication, with an auto-lubrication system available with grease lubrication. Side plates are made of hot rolled semi-killed/killed steel and the decks along with reinforcement plates are Huck-bolted to the side plates. The robust tubular deck frames are made of hollow sections and fabricated structures.
Feed tray and discharge lips are provided with abrasion resistant liners. The screen box is made of weld-free construction to reduce stress concentration. The screen mechanism consists of steel eccentric shaft mounted in vibration screen duty self aligning spherical roller bearings, designed for longer bearing life. The stroke can be adjusted as per requirements by changing the counterweights mounted on the flywheels.
The screens can be converted into a rinsing screen by adding the rinser kit at site. Optionally, they are also available with dust encapsulation arrangement.
