RATTLER Russian patent published in 2009 - IPC B02C17/00 

FIELD: mining.

SUBSTANCE: this invention refers to the technology of the hard material reduction. The rattler consists of multisectional cylinder each section whereof is composed of quadrangles with the formation of the square sections at the ends. The square is turned relative to the square of the previous section for 90°. Quadrangles are made of big and small rectangles and two identical trapeziums bottom bases whereof are equal to the side face of big rectangle, and upper bases are equal to the side face of small rectangle. Side faces of trapeziums are equal to the rest two sides of big and small rectangles with the formation of the quadrates multi-inclined into different directions and to the axis of the sections at the ends whereof. It also includes loading and unloading mechanisms and the drive assembled within the frame hung by rubber-cord pneumobottles to the bed plate. The cylinder is assembled out of the sections each assembled of rectangle bases and two side faces in the form of two isosceles triangles fixed by their bases under the 90° angle to the big sides of the rectangle base. The length of the smallest side of the rectangular base is equal to the length of each of four of side faces of the isosceles triangles with the formation of multiturn helical surface, four polygonal helical lines of the main direction directed towards each other and two polygonal helical lines of the opposite direction. They are formed along the perimetre of the cylinder.

EFFECT: expansion of the cylinder's features.
