Trials Of Unique Tyre Grinding Machine Completed

Rubber Recovery has designed a unique grinding machine for tyres from 1.4m to 2.3m that has just successfully finished its production trials.

Reducing end-of-life car tyres to rubber crumb is nothing new.

But what about earthmoving vehicle tyres - those over 1.4m for which there have been no recycling options? Thanks to the ground-breaking development work undertaken by the process partnership, Rubber Recovery, this gap has now been bridged.

It has designed a unique grinding machine for tyres from 1.4m to 2.3m that has just successfully finished its production trials.

Rubber Recovery has impressive credentials.

It is a subsidiary of Montpellier, the diverse construction group whose annual turnover is in excess of £500 million.

The development of this machine is a very important step as it benefits both public health and the environment.

It also makes available, valuable raw material for re-use in the manufacture of secondary products.

The current policy towards unwanted large vehicle tyres is especially wasteful as the rubber and steel used to produce them are of exceptionally high quality.

In the absence of a method to crumb earthmoving vehicle tyres there has been no option but for them to be deposited whole in landfill sites, the cost of which can be substantial.

This is far from being a 'green' solution as the tyres occupy considerable disposal space.

They also harbour rainwater and as the Health Protection Agency has recently advised, this creates the perfect breeding ground for mosquitoes.

Rubber Recovery's new grinding machine is not designed just to reduce the tyre to scrap.

It extracts both rubber and steel from the tyre, rendering both suitable for re-use.

Dependent on the cutter formation chosen and the grades of rubber produced, the resultant crumb is a valuable secondary raw material.

There is a considerable premium on finer grades and a higher requirement in UK manufacturing for virgin rubber.

The robust patented machine comprises a strengthened steel frame that supports a double hydraulic ram system mounted on roller bearings.

These rams hold and rotate the tyre in adaptor rims located in the tyre beads.

The tyre is ground whilst turning and the crumb expelled via a jet of air into a dust and chip collecting system, ready for further grading and bagging.
