\\ Tyre Shredding Plants
Introduction
Brentwood has been manufacturing and supplying shredding machines for processing car and truck tyres for many years. Through extensive R & D and interactive liaison with our customers, our current range offers the latest technology in tyre shredding and processing.
As steel radial tyres are one of the most difficult products to shred in our industrial age, particular attention has been paid to developing machinery with superior working life and reducing maintenance.
 |
Brentwood offer a large range of machines with many diverse cutter arrangements. This allows us to provide machinery to produce various product sizes required for primary or secondary processing. This can be achieved by cutter selection, multi shredder plants or screening.
Tyre shredding is a world wide necessity due to environmental controls restricting the dumping of whole tyres. Innovative industry are continually using shredded tyre for purposes such as fuel for kilns, retaining wall fill, 25 - 50mm chip for road base, municipal tip cover. Extensive use of rubber chip for production of rubber crumb is now common place. |
As the charges for dumping whole tyres are increasing, new business opportunities are emerging. Fees for tyre removal are charged, which incorporates sufficient funds to allow shredding prior to further processing or disposal.
Our latest technology includes a tyre crumbing plant with a unique modular design. This allows production of rubber crumb with separation of steel and fibre.
Tyre Shredding Machines Available

Brentwood Engineers can assist in the selection of correct machinery to suit a particular application. In determining this, the following consideration must be addressed:
The following provides capacities of various model shredders and the expected maintenance considerations: |

The AZ-50HD - This machine is a good entry level unit capable of shredding up to 300 car tyres per hour. The lower capital cost provides opportunities for smaller businesses to shred tyres. This machine is supplied with 37kW electric drive. Maintenance expenses on this machine are obviously higher than the larger machines in the Brentwood range. This machine is also used as a secondary shredder in our Multi Purpose Shredder plants or Classifiers for the production of tyre chip.
The AZ-100HD is the machine which can be used as the primary plant of the Multi-Shredder Chipping Plant. It can be used to process car, light truck tyres. Based on the construction of the Az 150W this machine is equipped with the largest shafts, bearings & gears available from Brentwood. This machine is supplied with 75kW electric drive. The machine can handle about 600 - 800 car tyres per hour but produces a fairly large product, which it is then necessary to shred through a secondary process. This machine provides high production rates on car tyres with lower maintenance levels.
The AZ-150W is Brentwood's largest machine. It will handle truck tyres without debeading. However, we recommend debeading, because this will reduce the maintenance costs on the machine. If you intend to install a crumbing plant, the removal of the bead is essential. The machine can handle 1000 car tyres per hour and up to 200 truck tyres per hour. Power supply requirements are high due to a 110kW drive and DOL start.
The product from this machine can be kept to a size which is close to the EPA's specifications without a secondary shred provided the truck tyres are debeaded. This is acheived 47mm cutters and production rate is 120 tyres per hour. In order to process undebeaded truck tyres, the cutters are wider producing larger pieces.
Classifier
|
On all of the above machines, a Classifier
Screen is available. This is a small trommel screen which
rotates around the shredder and has holes in it to determine
the size of the output product. The material which does not
go through the holes on the first pass is returned to the
shredder for more shredding. Obviously depending upon the
size of the product, this effects the production rate
through the machine.
For example with an AZ-150W, aiming at a product within the EPA specification of 250 x 250mm, the production rate on car tyres in this machine will drop from 1000 to about 500 - 600 per hour.
Multiple Shredding Plants for ChipOur standard Multiple Shredding Plant to produce a 40mm rubber chip.This is acheived by using a primary shredder and then processing through secondary AZ40 shredders fitted with classifiers. The product is excellent for fuel purposes and for fill. The chip from this plant is suitable for feeding into our tyre grinding plants.
ElectricalElectrical supply needs are high and you should keep in mind that the power requirement is to be considered on the basis that the shredder starts Direct on Line. |
