The most common application of a vibrating screen is to separate an unconfined conglomerate of materials into different size fractions. Other popular uses of screens are scalping, washing, dewatering and dedusting. A review of the duty is essential to know the type of screen to recommend.
The Step Screen has the highest hydraulic capacity of any fine screen due to its larger open surface area when compared to any other Fine Screen technology. Step Screens are available with either 3mm or 2mm thick movable and 3mm or 2mm fixed lamellas. For the 2mm option, the open surface area for a clean screen is 75% (3mm thick lamellas = 60%).
Unified SuperFlow Screens are an advanced combination of wire and polyurethane. The screens are designed to eliminate wire-to-wire contact. When material falls on the screen, the wires vibrate at their own frequency, allowing material to slip through while maintaining accurate material sizing.
AEI Screens offers high-quality screening solutions for the aggregate and mining industries. The BIVITEC dual vibratory screen is an excellent option for screening challenging materials without plugging and blinding the screen. Meanwhile, the Ortner is a high efficiency solution for washing and dewatering fines like manufactured sand.
High-frequency screens, for example, are used for separating fines through a high-speed small-stroke action. They are often used for processing sand, metal powders and chemicals. Dewatering screens are used in situations where material is washed.
