Construction of a New Primary Crushing Unit (KET-3) at “Ellatzite” Mine

Employer: Ellatzite-Med AD

Designer: Geoproject EOOD

Contractor: Geostroy EAD

Project execution period: 2006 – 2009

Description of the project:

The new primary crushing unit (KET-3) consists of a trestle, a transfer house supplied with a tension station and a transportation gallery.

KET-3 is built of reinforced concrete and steel. The facility has a total built-up area of 820 sq.m.  It is equipped with two crushers “Allis” and “Krupp” which are serviced by a crane with a hoisting capacity of 100/30 tons.

The foundation was constructed on a solid ground using a 1800-mm thick foundation slab. The earthworks, necessary for reaching the elevation of the foundation (-26.75 m), were carried out by means of blasting. The foundation slab, columns, floor structures and walls are monolithic. The whole facility is built as a monolithic frame structure with multiple outsets and floors, and with walls, beams and columns that bear horizontal forces and vertical impacts.

Conducted works:

  • Concrete works – 16,000 cub.m.
  • Steel structures – 1300 t
  • Large-size metal formwork – 32,000 sq.m.
