UiK KD 800-1200
Dynamic crusher type UiK KD 800-1200 is intended for crushing coal and rocks in order to facilitate its further transport, especially at transfer points. It is located in a heading in the route of the beam stage loader with pan widths of 750 to 1104 mm. The crusher is driven by an flange electric motor with in an anti-explosion version.
It can be applied in headings with “a”, “b” or “c” level of methane explosion risk, as well as rating “A” and “B” of coal dust explosion risk at methane concentration in the surrounding atmosphere not exceeding values defined in applicable regulations.
