Concrete and concrete products recycling machine

Processing of large concrete waste

A significant number of construction projects of residential and industrial complex of Russia was built in the 60s of last century. Reinforced concrete, which is the basic building blocks of these objects have already exhausted its resources. By now, it is very relevant to recycle and reuse of materials from the disassembly of residential buildings and industrial facilities. Reuse of concrete seems appropriate because further use of steel reinforcement and coarse aggregate.

Substandard and damaged concrete and concrete products, construction products, and who have served their sentences, obtained during dismantling of buildings, waste building materials after processing are converted into construction rubble of secondary origin in accordance with GOST 25137-82 and the reinforcing steel.

Application areas of recycled concrete rubble :

• Arrangement of gravel base under the floors and foundations of buildings;
• Under the asphalt pavement of all classes;
• As a coarse aggregate in concrete strength of 5 … 20 MPa;
• The manufacture of concrete and concrete products;
• When filling of temporary roads;
• In podsypku for all types of paving lanes;
• If a car park and raise a paved area;
• To replace the soil in the backfill;
• Under the foundation base;
• In landscape architecture.

Complex processing of substandard reinforced concrete slabs and concrete waste

The processing plant is designed for remediation of substandard concrete products (slabs) and concrete waste in the gravel with associated fittings for metal extraction. The system is designed for processing substandard concrete products (slabs) and concrete waste in the gravel extraction with associated fittings for scrap.

The main stages of processing substandard concrete are:

• Destruction of substandard concrete (grade 500) to install a pressure of up to sizes not exceeding 200 mm, with the release valve;
• Fractionation by thunder;
• Crushing larger pieces on the crusher.

Concrete and concrete products recycling technology:

Large concrete slabs, substandard load on the table, press the crane, crane girder or some other mechanism. Panels or pieces of concretes are to put on the table to tie the straps. Removal of fixtures can be done the same crane for disposal.
Primary crushing of concrete products with the release valve is installed on a press. The unit has a fixed grate table, and the product moves along the table to the press and the destruction of the structure occurs in pieces of 200 mm.

Pieces of shattered concrete fall on the conveyor with a special tape, which is protected from possible damage pieces of rebar. Iron separator installed above the conveyor to collect the remaining fixtures.

Next, pieces of concrete with the size of 0-200 mm by an inclined conveyor will be fed to the unit with a bang, where the screening of the required fraction. Large pieces come in a crusher for secondary crushing, and then returned to the roar of the fractionation.

The technical solution of concrete Recycling

The unit has a fixed grate table, and the product moves along the table to the press, damaging the product. The maximum dimensions of the processed products 12 x 1.5 x 0.6 m.

• Press force 1600 KN. Failure occurs in cycles lanes wide and 200 mm at full width of the panel being processed.
• Press the installation has hydraulic working bodies.
• Performance depends on the nature of processed substandard.

When peperabotke nearmirovannnyh concrete waste it is 15 tons per hour, and when peperabotke substandard concrete products – 10 tons per hour. The performance consists of time spent on loading the desktop, and just the process of destruction of substandard concrete.

Recycling of waste concrete products

The design of the complex provides for the dismantling and transportation of its individual parts, do not require complex foundations and pits. For assembly of the complex, usually enough to have leveled concreted or stacked road slabs site.
