Background introduction
• As the need for superior quality increases processors are adding more quality inspections to their processes
• Positive pressure screening has been identified as a valuable potential market where Russell Finex can achieve sales
• A need to screen incoming ingredients during dilute phase pneumatic conveying was identified.
• Customers need to screen incoming ingredients without slowing down the delivery/unloading process
Background introduction
• Some of our competitors are already exploiting this market
• Russell Finex have the expertise to provide better solutions to the problems associated with positive pressure sieving
• Pressurised panwork has been developed previously for the C600 C.I.P.
The Blow Thru Sieve Introduction
• Completely enclosed vibratory screener
• Fully certified pressure vessel
• 2 dished body sections connected by a hinge
• No spacer or magnet
• Mesh frames modified with cross members. Larger than standard Compact 600
• 2 inspection ports as standard
The Blow Thru Sieve Introduction
• Oversize outlet not yet available but will be later on
• 3 lifting lugs
• Minimum mesh size at present is 1000 micron. This may change as we get experience.
How it works
• Material enters the sieve under pressure via a tangential inlet
• Good product passes through the mesh
• Oversize material is collected on top of the mesh
• Good material passes out of the sieve via an outlet at the bottom

Main benefits to customers
• Removes contamination to improve product quality and ensure customers reputation
• Screening and conveying in one process increases efficiency by eliminating double handling/processing
• Completely enclosed screening reduces mess and potential harm to operators
• The fully mobile unit can be used at multiple locations in one site
Benefits over Competitors
• Fully certified and tested for use in a positive pressure line
• Constructed to PD5500.
• Conforms to pressure equipment directive 97/23/EC.
• High throughput rates are achieved with straight through design and tangential inlet and outlet
• Disassembly is an easy task due to simple design and is achieved using a single inclusive tool
• Safety features – Lock-off system prevents
accidental closing during cleaning– Spring assisted opening limits
manual lifting
