It finds application in ore enrichment, production of construction materials, waste processing and other industrial branches. The grinding body comprises a spheroidal cone, whose forming curve is part of a circle or of some other geometrical curve and a vertex, and a base which is part of a sphere or of other three-dimensional figure, obtained by rotation of geometrical curves and an edge between them. In one of the versions the cone and the base are connected by a cylinder. For better producibility of the grinding body, a flat spot with circular or other shape is made on the surface of the base. In another version the flat spots are made on the surface of the cone and on the surface of the cylinder between the base and the cone. In a subsequent version the vertex of the cone is cut flat with its plane perpendicular or inclined towards the axis of the body. In other versions, more or less convex peripheral rings are made between the cone and the base. The cross section of these rings has the shape resembling a circle, a triangle or a rectangle. In a subsequent version on the base and on the flat cut vertex short cylinders with flat bases are protruding. All edges and the vertex of the body may be rounded along part of a circle, spiral or other geometrical figure. The grinding body has greater area than the spherical grinding body and greater density in a given space. The existence of an edge and a vertex increases milling productivity. ## Claims ### Claim 1 A grinding body formed by a spheroidal cone (1) with a convex forming curve (5) and a vertex (6), and a base (2) which is part of a sphere, characterized in that an edge (4) or a cylinder (9) or a peripheral ring (10, 11, 12) is formed between the cone (1) and the base (2), where a flat spot (3, 7, 8) is formed on the surface of the base (2) or on the surface of the cone (1) or on the surface of the cylinder (9). ### Claim 2 (depends on 1) A grinding body according to claim 1, characterized in that the curve (5) forming the cone (1) is part of a circle or of other geometrical curve. ### Claim 3 (depends on 1) A grinding body according to claim 1, characterized in that the base (2) of the body is part of a sphere or other three-dimensional figure, made by rotation of geometrical curves. ### Claim 4 (depends on 1) A grinding body according to claim 1, characterized in that the curves, forming the cone (1) and the base (2) are equal or different in length and/or in shape. ### Claim 5 (depends on 1) A grinding body according to claim 1, characterized in that the flat spot on the base (2), on the cone (1) or on the cylinder (9) has a circular or other shape. ### Claim 6 (depends on 1) A grinding body according to claim 1, characterized in that the vertex (6a) of the spheroidal cone (1) is cut flat with its plane perpendicular or inclined to the axis of the body, which (axis) passes through the vertex (6) before the flat cut and through the centre of the body. ### Claim 7 (depends on 1) A grinding body according to claim 1, characterized in that between the cone (1) and the base (2) a peripheral ring (10) is formed, more or less convex, whose cross section is near in shape to a circle or other geometrical curve. ### Claim 8 (depends on 1) A grinding body according to claim 1, characterized in that between the cone (1) and the base (2), a peripheral ring (11) is formed, whose cross section resembles a triangle. ### Claim 9 (depends on 1) A grinding body according to claim 1, characterized in that between the cone (1) and the base (2) a peripheral ring (12) is formed, whose cross section resembles a rectangle. 8 ### Claim 10 (depends on 1) A grinding body according to claim 1, characterized in that protruding short cylinders (13) with flat bases (14) are formed on the base (2) and on the cut flat vertex (6a). ### Claim 11 (depends on 1) A grinding body according to claim 1, characterized in that all edges and the vertex are rounded and the rounding is a part of a circle, spiral or other geometrical curve.
