PROJECT ESSENCE

The technology involves the integrated processing of construction materials generated as wastes in the production of reinforced concrete structures and the production of modern secondary products (metal, crushed stone, and sand) that can be reused in production and sold as conditioned products by other construction companies.

APPLICATION AREA 

The technology belongs to the category of "green recycling”, which deals with deep waste processing, i.e. the extraction of valuable materials that can be reused in various technological processes (including industrial construction). Such technologies are widespread in the EU and form the basis of the sustainable development concept. In addition, they can be offered for the processing of building materials removed during the dismantling of destroyed buildings in the areas of destruction (which are classified as man-made raw materials).

END PRODUCTS

Different contaminant levels and variability of input materials require individualized approach to each processing plant of construction wastes.
• Processed send 0.1-2 mm and 2-4 mm;
• Recycled crushed stone 4-8 mm, 8-11 mm
and 10- 20 mm
• Removedіmetal components;
• Removed lightweight components (plastic,
wood, paper).

PROJECT ESSENCE

Improving the control method of an asynchronous machine, in which the introduction of new technological operations and parameters makes it possible to control rationally energy consumption during the steady-state period regardless the actual load, an integrated approach to economy at all levels of the electromechanical system and reduction of dynamic forces in transient modes.

RESULTS OF PREVIOUS RESEARCH

The parameters of a nonlinear smooth control regulator are determined, which allows to achieve a significant reduction in power consumption when changing the power supply parameter. On the example of a serial engine, the parameters of the local reactive power compensation system are determined and the limit of switching relay control is substantiated. The possibility of obtaining a two-zone step control system for an asynchronous drive with a slight improvement of relay control, which ensures a maximal energy efficiency at all levels of the electromechanical system, is proved. A hardware solution for an integrated efficiency improvement system has been created and tested, which implements an integrated approach to solving the problem. Quantitative recommendations for the development of an integrated control system are given.

 ADVANTAGES AND EFFICIENCY

Simplicity and reliability, affordability and sufficient consumer quality. According to the results of experimental studies, the potential energy saving capability is up to 40% of active and 51% of reactive power.

PROJECT ESSENCE

The technology involves enrichment ofthe associated sand to meet EN (ASTM) specifications and forced accelerated settling of clay particles of used water, which will reduce the consumption of process water and reduce the volume of construction work on the sludge storage facility.

APPLICATION AREA 

The use of a deep enrichment module as a "green recycling" module to produce high-qualityenriched washed fractions from granite or limestones creening will allow the production of paving stonesor FEM tiles.

END PRODUCTS

The raw material fraction is 5-10 mm, 2-5 mm, 0.63-2 mm 0.06-0.63 mm and 0-0.06 mm. Process water of accelerated rotation due to the use of peptizers (relevant in the summer period of operation or in areas with reduced water inflow).
