Abstract
The invention relates to an ore grinding medium, which is characterized by comprising a multi-surface prismoid located in the middle section and a frustum extending from the bottom to two ends of the multi-surface prismoid, and the number of the sides of the multi-surface prismoid is not less than 5. The ore grinding medium provided by the invention is capable of reducing the abrasion of the ore grinding medium and a lining plate of a grinding machine and obviously improving the ore grinding efficiency.
Description
Technical field
The present invention relates to a kind of milling medium, relate 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 affect 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 put and put the way of contact and grind with ore, be unfavorable for carrying out fine grinding, but often caused thick and caused metal loss, so that the metal material consumption is large, reduce grinding efficiency.For cylindrical and truncated cone-shaped milling medium, although 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 unsuitable 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 mutually cutting, thereby the consumption of aggravation milling medium and the wearing and tearing of lining board of grinder.
For addressing the above problem, patent of invention ZL200620120216.2 discloses a kind of milling medium, it comprises cylindrical portion, the arc sections from cylindrical portion to the two ends extension that is positioned at the stage casing and the end face portion that is positioned at two ends, this cylindrical portion is cylindrical, 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 cylindrical 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, only having when both ends of the surface contact is the face contact.Therefore, the milling medium of foregoing invention patent contacts with line as main take 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.
Summary of the invention
In order further to improve the grinding efficiency of milling medium, the invention 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 described polygonal prism cylinder is equal to or greater than 5.
Preferably, described prism is regular prism, and preferably, and the ratio of the length h of described prism and the external diameter of a circle D in its bottom surface is in 0.3～5 scope.
Alternatively, described prism is the slant edge cylinder.
Preferably, the side of described prism is 6-12.
Preferably, the side of described frustum is arc surface.
Alternatively, the side of described frustum is the plane.
Alternatively, rounding off between each side of described prism.
Because the present invention is made of the prism that is positioned at the stage casing and the frustum that extends to two ends 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, wherein the ratio of face contact is larger, and it is particularly suitable for the method for the many broken few mills of present ore dressing industry.Therefore milling medium of the present invention can reduce the wearing and tearing of milling medium and lining board of grinder, can improve significantly grinding efficiency again.

The specific embodiment
Embodiments of the invention are described below with reference to the accompanying drawings.Take positive eight prismatic and positive seven prisms as example is described, the number that the side of stage casing of the present invention prism is described both can be odd number to accompanying drawing, also can be even number respectively.
Shown in Fig. 1 and 2 be according to prism of the present invention be positive eight prisms, top view and the front view of milling medium 1 when the frustum side is arc surface.As shown in the figure, milling medium 1 comprises positive eight prisms 2 that are positioned at the stage casing and the frustum 3 that extends to two ends from the bottom surface of polygonal prism cylinder, and wherein the side of frustum is arc surface, and the end face at frustum two ends is the plane.
Wherein, the length of positive eight prisms is h, and the external diameter of a circle in its bottom surface is D, and diameter D is slightly larger than the length h of positive eight prisms in the present embodiment.According to practice, preferably, the ratio h of the length h of positive eight prisms and the external diameter of a circle D in its bottom surface: D is in 0.3～5 scope.
Because the stage casing of milling medium is eight prisms that are made of eight planes, and two ends are the frustums that formed by arc surface, therefore in grinding process, the way of contact is that the face contact contacts with line substantially, and wherein the ratio of face contact is larger.Improve thus grinding efficiency, reduced simultaneously the wearing and tearing of milling medium and lining board of grinder.
