Russell Finex, Inc.
Russell Finex announces its Blow Thru Sieve, which removes oversize contamination from powders during dilute-phase pneumatic conveying, enabling processors to screen and transport material simultaneously. It is suitable for screening powders from delivery tankers before storage, before filling tankers at dispatch, and other operations in which powders are pneumatically conveyed.
By combining material screening and transport, the sieve eliminates double handling, thus increasing efficiency. Product is conveyed under pressure into the sieve through a tangential inlet, ensuring that high throughput rates up to 60,000 lbs. per hour as recorded in on-site customer trials can be achieved with minimal pressure losses. Appropriately sized product is allowed to pass through the vibrating mesh screen while oversized material remains on top, where it can be removed at the end of a batch.
As the Blow Thru Sieve conforms to European Pressure Equipment Directive 97/23/EC, it is certified for use up to a maximum pressure of 2 bar in Europe, and is suitable for use up to 1 bar pressure (14.5 psi) in North America. The unit assembles and disassembles using a single tool to allow quick and easy cleaning between batches. The sieve is mounted on a mobile stand so that it can be used at multiple on-site locations.
The manufacturer says it has designed the unit to be operator-friendly, with an easily accessible inlet/outlet, operator safeguards and a spring-assisted lid hinge. Once opened, the lid is secured in the open position by a positive lock-off system, which frees the operator's hands for any cleaning or maintenance and prevents the lid from accidentally closing.
The Blow Thru Sieve is available with FDA-approved materials and surface finishes for pharmaceutical operations, and a variety of connections are available for complete compatibility with existing processes and equipment.
