Paper – Security Shredding
Paper shredding – tougher than you might think
Paper shredding and secure document destruction – tougher than you might think. Shredding paper is easy right? Well think again. Document security shredding is one of the toughest applications for a shredder due to the characteristics of layered/compressed/bound paper. This material absorbs the energy from the force of the cutters as it compresses until it reaches a shear point and shreds. If the layer of paper is too thick – the shredder will overload. So the trick is to ensure that the shredder receives the right amount of paper for maximum shredding efficiency, but not too much paper that would cause the unit to overload and reverse.
Paper Strip Shredders
Brentwood offer a range of security strip shredders as either an integrated solution including an infeed conveyor and guarding or as a stand-alone unit to enable integration into an existing plant. The width of the strip is equivalent to the cutter width and the length will be variable based on the infeed material. General industrial secure document shredding requires a maximum strip width of 5/8 inch (15.9mm) with an indefinite length. We offer cutter widths of 12mm and 16mm which are acceptable under most security conditions. They are extremely efficient and perform at a considerably increased rate per hour compared to shredders fitted with feed hoppers. By using a duplicated shredder system, cross-cut shredding can be achieved.
Our SS15WL, SS50HD, and SS100/2 paper strip shredders are typically used for secure document destruction.

Pierce & Tear Paper Shredders
Brentwood offers a wide range of pierce and tear (hooked cutter) shredders for secure document destruction. Hook style shredders can be supplied with 20mm, 31mm, or 47mm triple hook cutters. These are a special design cutters for the high loads seen in paper shredding. Output size is the same as the width of the cutter and 50-75mm long. The output from this type of shredder is suitable for baling.
Our AZ15WL, AZ50HD, and AZ100/2 dual shaft shredders are typically used for document shredding.

Paper Plant Designs
Everyone has different requirements when it comes to paper shredding and secure document destruction. That’s why we specialise in building customised plants. Once we have a clear understanding of your requirements, we will design a plant featuring our core technologies to achieve your throughput and sizing requirements.
Shown below are just a few of our document shredding plant designs – each with their own unique requirement. Talk to us about how we can design a plant to suit your needs today.
Sorting and Shredding Plant with Bin Lifter
This plant is designed for users who receive their material for shredding in 240L bins. A 2 man sorting station allows for unshreddables to be removed before transfer to the shredder. An AZ50HD shredder capable of 2 to 2.5T/hr discharges onto a conveyor to feed a baler.
Paper Shredding Plant with Dual Discharge Arrangement
This plant is fed using a pit conveyor to allow material to be pushed onto the belt using a bobcat or similar. An AZ50HD shredder shreds the paper at 2 to 2.5T/hr and discharges onto the main discharge conveyer. This conveyor can be reversed to route shredded paper to the secondary discharge conveyor.
Paper Sorting and Shredding Plant – With Strip shredder
This plant features a small metering conveyor fed by bin tipper which feeds onto a picking belt and then into a Security Strip Shredder with discharge onto a baler feed conveyor.
Paper Shredding Plant with Metered Bulk Feeder
A VSD controlled bulk feeder allows for full bins/cages to be tipped into the main hopper. This feeder slowly advances the paper onto the shredder infeed conveyor to ensure a metered feed to the shredder. Discharge from the shredder is into an air extraction system.
