Description
Technical field
The utility model relates to a kind of multi-functional many ribs abrading-ball using in ore mill.
Background technology
In ore dressing industry, conventionally, by means of impact and the mill stripping effect of milling medium and ore itself, the granularity of ore is diminished gradually, until grind into powder.The object of doing is like this to make to form the valuable mineral of ore and gangue mineral to reach to greatest extent and dissociate, so that the material that meets next beneficiating process requirement in granularity to be provided.The shape of milling medium, size, material can directly affect the waste 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.
In process of lapping, abrasive body determines the fine degree of grinding with the way of contact that is polished object.As known in the art, at abrasive body, when being polished object and carrying out contacting, result is to be polished object to be roughly ground, and forms larger particle; Abrasive body be polished object and carry out line while contacting, result is to be polished object to be subject to middle mill, forms medium sized particle; Abrasive body be polished object and carry out face while contacting, result is to be polished object to be subject to fine grinding, forms the particle of less and even powdery.
The milling medium using in ore mill is at present called again abrading-ball, it is generally spheroidal, cylindrical, truncated cone-shaped etc., for spheroidal abrading-ball, in ore mill, its mode with a contact is ground ore, corase grind efficiency is very high, but is unfavorable for fine grinding, therefore often causes ore particles after grinding to cross thick and causes metal loss, make metal material loss quantitative change large, reduce grinding efficiency.For cylindrical and truncated cone-shaped abrading-ball, although the way of contact that they have comprised point, line, surface, the amount that some contact contacts with line contacts much larger than face, is suitable for corase grind, middle mill, but is unsuitable for fine grinding.
For addressing the above problem, utility model patent ZL200620120216.2 discloses a kind of milling medium, it comprises cylindrical portion, the arc sections of extending to two ends from cylindrical portion that is positioned at 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 rounded, and round diameter is d, and D>d, arc sections is from cylindrical portion to end face portion, to form circular arc transition.
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 line contact when the face of cylinder contacts, only having when both ends of the surface contact is face contact.Therefore, the milling medium of above-mentioned utility model patent be take a contact and is contacted with line as main in grinding process, and its grinding efficiency needs further to be improved.
