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
