LINATEX G3 Rotary Screens

Linatex® G3 Rotary Screens consist of a rotating cylindrical drum supported on four heavy-duty polyurethane support rollers in the case of the three, five and seven module units. The single module drum is cantilevered on a central stub shaft, which rotates in two heavy-duty bearings
 

The drum is of a tubular space frame design with box ends into which the tubes are welded. For the three larger machines these ends form the tracks, which contract the support rollers. The design allows a variety of different filtering mesh membranes to be fitted. The cloth is visible during rotation and thus easily inspected for wear or damage
 

The screen cloth (Type 304 stainless steel woven wire or woven polyester monofilament or other synthetic mesh) is attached to the drum by special two part plastic rivets and rubber-faced stainless steel clamping straps. Removing or fitting the screen cloth is a simple operation. No tracking of the cloth is required
 

The feed to the screen is evenly distributed by the feed box down the length of the drum. Oversize material is retained on the screen cloth with liquid and undersize particles passing through into the underpan. As the drum rotates, the oversize material held on the inside of the screen cloth is first rinsed by the internal spray nozzles. The tramp material is further transported, with assistance from the longitudinal lifters, before being washed off by the external spray nozzles into the discharge launder for disposal outside the unit. A supply of clean water is required outside the unit. A supply nozzle enters the process stream while a stream from the external spray nozzles keeps the screen cloth clean and carries the oversize material away

The drum is positively rotated via a simplex chain sprocket connected through vee-belts to a shift mounted gear reducer, which completes the drive

Selection Process:  Screen capacities can vary widely depending on the material characteristics and the separation required. Our process and application engineers are able to draw on their many years of experience and intricate knowledge of numerous worldwide installations to ensure that the most appropriate screen size and best screen configuration is selected for your projects.

The following factors should be considered

• Type of material to be screened

• Feed rate

• Bulk density of material
