Job Report Rubble Recycling Plant for Greater Munich - Hazemag

Plant Description
Job Report
This crawler-mounted mobile recycling plant is used to process building rubble, concrete and
broken asphalt paving to generate a classified high-quality end product. This compact unit accommodates
all the necessary processing stages – pre-screening, crushing, control screening
and metal separation – characterising the exceptional mobility of the recycling plant on the
work site.
The plant is fed by hydraulic excavator. By means of a vibrating feeder with variable drive, the
raw material is delivered to an eccentric screen which separates the material at 45 mm and
10 mm. The < 10 mm fines are discharged by a separate belt conveyor, and the
10 - 45 mm fraction is re-united with the product flow downstream of the crusher.
The > 45 mm material is selectively crushed in the impactor, in other words, all re-bars and
the like are separated from the actual concrete. The impact crusher, which has been specially
designed for use in the rugged recycling environment, is equipped with the latest hydraulically-
controlled impact apron support and adjustment system, which retains the aprons securely
and reliably in their pre-set position. On entry of any problem tramp metal, the impact aprons
retract to allow the passage of the tramp metal, automatically returning to their original pre-set
position as soon as the hazard has passed. This system ensures a high degree of operational
safety and consistent product quality. The material discharge is arranged in the rotational direction
of the impactor rotor, giving low trouble operation, even when concrete with a high rebar
content is being processed. Ferrous material is eliminated from the product by an over-belt
magnet and discharged in the direction of conveying. A downstream control screen separates
the small amount of oversize > 56 mm present in the product and which is then stockpiled and
returned to the impactor for re-processing as convenient. By means of conveyor belt, the product
0 – 56 mm is conveyed to the product stockpile.
Thanks to the selective crushing coupled with the outstanding technology, the end product
is an excellent recycling material which, by reason of its gradation, structure and quality, is a
valuable and highly-marketable product.
