On the territory of the Sosnovsky mine in Techa iron ore deposit will soon begin construction of a new crushing — sorting facility for the production of porphyritic rubble. The tender for the construction and production of crushed stone, announced LLC «Bakalskoe mining plant administration», won LLC «Heritage» (Kostomuksha).
With representatives of the contractor signed a contract to carry out works. At present, the forces of LLC «Bakalskoe mining plant administration» are a preparation site for the import of mobile crushing equipment supply to the industrial site utilities — water, electricity. In addition, the form feedstock for the production of crushed stone. Warehouse can accommodate half a million tons of porfirita (durable building stone).
Recall porphyritic crushed stone used for the construction of railways, roads, civil construction and concrete production. From this, in particular, make the building blocks, wall panels. Degree first category includes crushed flakiness not more than 15%, cuboid particle shape. «Flakiness» — one of the most important characteristics of the rubble, figures which are strictly accounted for in the production of various construction works. Use a flaky crushed to 15% in the production of concrete compaction provides a more dense, and, in turn, reduces the intergranular voidage of the mixture. This saves on the additional binder component. In addition, the cube-shaped crushed stone is highly durable, which is also economically viable and profitable producers of building materials.
