Description
Technical field
The utility model relates to a kind of milling medium, relates in particular to a kind of milling medium that in ore mill, uses.
Background technology
In the ore dressing industry, the shape of milling medium, size, material and interpolation quality directly can influence the consumption of grinding efficiency, metal recovery rate and metal material.Therefore, the research about the shape of milling medium, size, material is the research emphasis of this area always.
The milling medium that uses in the present ore mill (or claim abrasive body) is generally spheroidal, cylindrical, truncated cone-shaped etc.; For the spheroidal medium; In ore mill, be to grind, be unfavorable for carrying out fine grinding, but often cause thick and caused metal loss with the point and the some way of contact with ore; Make that the metal material consumption is big, reduce grinding efficiency.For cylindrical and truncated cone-shaped milling medium, though they have comprised the way of contact of point, line, surface, grinding particle size is thick, is suitable for corase grind, middle mill, but is inappropriate for fine grinding.And the edge of each cylinder, round platform can be cut on the lining board of grinder and cause between the milling medium cutting each other, thereby the consumption of aggravation milling medium and the wearing and tearing of lining board of grinder.
For addressing the above problem, utility model patent ZL200620120216.2 discloses a kind of milling medium, and it comprises the columnar portion that is positioned at the stage casing, the arc sections of extending to two ends from columnar portion and the end face portion that is positioned at two ends; This columnar portion is the cylinder bodily form; Diameter is D, and end face portion is a plane and rounded, and round diameter is d; And D＞d, arc sections is to form the circular arc transition from columnar portion to end face portion.
Above-mentioned milling medium has solved spheroidal, the cylindrical and existing problem of truncated cone-shaped milling medium to a certain extent.But when the contact Shi Weidian contact of its arc transition place, be the line contact when the face of cylinder contacts, having only when both ends of the surface contact is the face contact.Therefore, it is main that the milling medium of above-mentioned utility model patent contacts with line with a contact in grinding process, and its grinding efficiency remains further to be improved.
And; Technological improvement along with the ore dressing industry; Adopt the method for many broken few mills; Change into the present granularity below 20 millimeters by the mill feed size more than 50 millimeters in past, milling medium also should change its ore grinding principle thereupon, changes into present by being ground to the principle of pounding by common ball by pounding mill.
The utility model content
In order further to improve the grinding efficiency of milling medium; The utility model provides a kind of milling medium; It is characterized in that: comprise the polygonal prism cylinder that is positioned at the stage casing, from the frustum that extend to two ends the bottom surface of polygonal prism cylinder, the number of the side of said polygonal prism cylinder is equal to or greater than 5.
Preferably, said prism is the regular prism body, and preferably, and the ratio of the length h of said prism and the external diameter of a circle D in its bottom surface is in 0.3～5 scope.
Alternatively, said prism is the slant edge cylinder.
Preferably, the side of said prism is 6-12.
Preferably, the side of said frustum is an arc surface.
Alternatively, the side of said frustum is the plane.
Alternatively, rounding off between each side of said prism.
Because the utility model is to constitute to the frustum of two ends extension by the prism that is positioned at the stage casing with from the bottom surface of polygonal prism cylinder; Therefore; In the ore mill grinding process; The way of contact mainly is that the face contact contacts with line, and wherein the ratio of face contact is bigger, and it is particularly suitable for the method for the many broken few mills of present ore dressing industry.Therefore the milling medium of the utility model can reduce the wearing and tearing of milling medium and lining board of grinder, can improve grinding efficiency significantly again.
