Stainless Steel 316 Reverse Johnson Screen Rotary Screen Drum Cylinder Back Flush Screen
Product Description:
Reverse Wedge wire screen cylinder is made by Johnson screen mesh through reverse welding . Johnson screen mesh is welded by V wire and support rod.There is a fixed value slot between each v wire, and the continuous slot, designed to provide maximum open are to reduce entrance velocity, increase hydraulic efficiency and promote more effective development. The finished reverse wedge wire screen cylinder have a smooth inside.The filter screen cylinder has a number of longitudinal and horizontal ribs on the outside, greatly enhancing the anti-crushing strength of the sieve cylinder, especially suitable for sieving cylinder with rotating blades inside the extruder.

Other components : Flange, stiffener, lifting handle, and other type components by request.
Special specification can be made according to your need.
Advantages:
adoption of the wedged wires made a V profile slot. This design ensures the fluent of water filtration and more effective
The CNC machine tools strictly control the gap between the wire, so that the gap is even.
Stainless steel have the high corrosion resistance.
Filter from inside to outside , and the outside slot is bigger than inside slot, so it is easy to bakc flush.
Apply to Built-in scraper, brush, suction first class cleaning device.
easy operation, fine permeability, unaffected by temperature, long life service, safety and reliability, low comprehensive cost.
