Metso EF Series vibrating screens

Metso EF Series (Ellipti-Flo) of vibrating screens are a high performance banana style screen utilizing an elliptical motion with varying high to medium G acceleration which results in eliminating blinding and plugging for difficult to screen ores.

APPLICATIONS
Efficient with difficult to screen sticky ores
Use as standalone unit, or in a multi-stage process
Applicable industries: Minerals processing of all metallic and non-metallic ores (e.g. copper, gold, iron ore, silver, lead, nickel, zinc, molybdenum, bauxite, alumina, clays, and more)

Features
Self synchronized two shafts elliptical motion
High capacity banana shape
Side plates – completely huck-bolted assembly
V series vibrators
Oil or grease lubrication
Available in double deck models

Benefits
Elliptical motion provides non-binding, non-plugging performance
Self synchronized elliptical motion attained with no need for gears or timing belts
Optimize screen production and efficiency while in motion by an optional electronic synchronization device that provides the ability to adjust both stroke angle and speed while running
Global product support and application expertise with local dedicated experts

How it works?
The 1:3 ellipse ratio is generated by two lines of mechanisms positioned far from the screen gravity center, enabling self synchronism operation, eliminating the need of gears and timing belts.
With this unique feature, by electronic synchronization device, it is possible to adjust the stroke angle and speed with the machine in operation, optimizing the screening production and efficiency.

Unique benefit
The stroke angle is varied from the standard 45° to slow material flow. This varying the stroke angle on a pre-arranged time interval dislodges any material from the media aperatures
