Contra-shear® Milliscreen®
by Johnson Screens Australia
The Contra Shear Milliscreen is the industry standard when it comes to rotary fine screening. The Contrea Shear was developed in NZ over 35 years ago as the world’s first rotary screen. It’s self-cleaning, internally fed rotary screen with a range of slot sizes and gap types is suitable for a large range of industries and process streams with years of research and over 15,000 installations worldwide, Johnson Screens® has by far the most diverse application experience in the industry.
The Milliscreen is commonly installed above channel with the influent either pumped or flowing by gravity into the screen. A weir tank inside the screen drum balances the flow and distributes it evenly over the rotating screen drum. Solids are captured inside the screen drum where they are de-watered and discharged using a series of diverter plates.
The Milliscreen drum is cleaned by using water under moderate pressure through two sets of sparge pipes that operate intermittently through a control system.
The wide range of Milliscreen models are capable of handling flow rates from 0.6 to 3,360 m³/hr. Slot sizes from 0.25 to 6.0 mm with Vee-wire models and from 1.0 mm and up with perforated plate and mesh models.
