The Russell Blow Thru Sieve is inserted directly within vacuum or pressure pneumatic conveying lines and it check-screens dry, free-flowing powders and granular materials without disrupting processing lines.
When you consider how often these types of materials are moved using a pneumatic conveying transfer system, you will start to grasp the multitude of uses for this sieve.
The unique design of the Blow Thru Sieve check-screens and conveys product in one single operation providing improvements in quality without sacrificing productivity.
Product is conveyed under pressure into the sieve through a tangential inlet ensuring high throughput rates are achieved with minimal pressure losses. Good product is allowed to pass through the vibrating mesh screen, while oversize material remains on top where it can be removed at the end of a batch.
Nupac have identified three specific applications where the Blow Thru Sieve can prove to be effective in the manufacturing process.
The first application is check-screening incoming ingredients during tanker unloading to ensure down stream processes are free from contamination.
Secondly, the Blow Thru Sieve can be used to screen materials while they are pneumatically conveyed at any point throughout your production process.
The final application, screening product before it is dispatched, is the one that we feel is the most important. It ensures customers receive contamination free products, safeguarding your reputation.
The Blow Thru Sieve also eliminates the need for auxiliary equipment such as cyclone receivers, airlocks, receiving hoppers and blowers generally required when using standard atmospheric pressure sieving units.
Its well thought out design not only provides for reduced maintenance costs but requires minimal operator involvement resulting is substantial cost savings. Dis-assembly of the unit is fast and simple, clamps release the lid of the unit so it can be can be lifted open. Once open, a positive lock-off system secures the lid, giving operators complete access for cleaning or maintenance.
