Demolition rubble recycling plant

The state-of-the-art process for recycling construction wastes containing reinforced concrete involves imported from abroad  jaw and cone crushers, double deck screens and belt conveyors..

The use of conventional jaw crushers for coarse crushing implies frequent failures  caused by uncrushable objects found in the crushing chamber.. The cone crushers used on the secondary crushing stage fail to yield aggregate with low content of slivers and needle-shaped particles.

As distinct from those the processing line developed by Mekhanobr-Tekhnika comprises a vibrating jaw cruser, a vibrating cone crusher and a triple deck vibrating  screen.

 

Application:

The plant can be employed for processing demolition rubble containing reinforced concrete to obtain secondary aggregate
