The abrasion-resistant sphere with the plurality of spherical protrusions comprises a first abrasion-resistant sleeve, a second abrasion-resistant sleeve and an abrasion sphere body, wherein the plurality of spherical protrusions are formed in the outer side of the first abrasion-resistant sleeve; semicircular spherical cavities are formed in the inner side; the number of the semicircular spherical cavities is equal to the number of the plurality of spherical protrusions; the semi-diameter of any semicircular spherical cavity in the plurality of the semicircular spherical cavities is equal to the semi-diameter of the abrasion sphere body; a convex side is arranged on the end face of the inner side; spherical protrusions are formed in the outer side of the second abrasion-resistant sleeve; the number of the spherical protrusions is equal to the number of the spherical protrusions which are formed in the outer side of the first abrasion-resistant sleeve; semi-spherical cavities are formed in the inner side; the number of the semi-spherical cavities is equal to the number of semi-spherical cavities which are formed in the inner side of the first abrasion-resistant sleeve; a groove is formed in the end face of the inner side and matched with the convex side of the end face of the inner side of the first abrasion-resistant sleeve; the first abrasion-resistant sleeve is mutually engaged with the second abrasion-resistant sleeve; and the abrasion sphere body is wrapped by the first abrasion-resistant sleeve and the second abrasion-resistant sleeve. The abrasion-resistant sphere with the plurality of spherical protrusions has the beneficial effect that the abrasion-resistant sphere is simple, novel and unique in product structure and capable of remarkably improving the production efficiency and greatly reducing the production cost.
Description
Technical field
The utility model relates to mining equiment part field, especially a kind of wear-resistant ball with a plurality of spheroid projections.
Background technology
At present cement, in ore deposit and metallurgical industry, the abrading-ball that the ball mill of disintegrating apparatus adopts is all cast by material integral material, mainly contains spherical abrading-ball, cylindrical mill section or frotton.Contacting operating mode or be point and contacting of putting between these abrasive medias and material in use, or be line and the contacting of line.Its Shortcomings is due to the restriction that is subject to specific area, therefore its operating efficiency is lower, ball surface is very easy to wear in addition, and distortion, causes grinding efficiency low, and energy consumption is high, and abrading-ball is changed frequent, and production cost is increased.If the frustum of a cone joint, capsule ball middle part in Chinese patent " Novel capsule ball abrasive media (patent No.: 01245362.5) " is not in smoothing junction, serious wear in use, in Chinese patent " a kind of combination wear-resistant ball (patent No.: 201220094493.6) ", abrading-ball be subject to specific area lower, operating efficiency is lower.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of wear-resistant ball with a plurality of spheroid projections, and the technical scheme of employing is as follows:
A wear-resistant ball with a plurality of spheroid projections, is characterized in that, comprises wear-resistant sleeve first, wear-resistant sleeve second and abrading-ball body; Described wear-resistant sleeve first outside is several spheroid projections, outer surface is provided with grid fin, inner side is provided with the cavity of several semi-round balls, and in described several semi-round ball cavitys, the radius of any one semi-round ball cavity equates with the radius of described abrading-ball body, and inner side end is provided with chimb; Described wear-resistant sleeve first and described relative engagement of wear-resistant sleeve second, described abrading-ball body is wrapped in the cavity of described wear-resistant sleeve first and wear-resistant sleeve second; The outside of described wear-resistant sleeve second is provided with the spheroid projection equating with quantity outside wear-resistant sleeve first, in several spheroid projections of each spheroid projection radius and described wear-resistant sleeve first, the protruding radius of any one spheroid equates, outer surface is provided with grid fin, inner side is provided with the semi-round ball cavity equating with quantity inside described wear-resistant sleeve first, the radius of each semi-round ball cavity equates with the radius of described abrading-ball body, inner side end is provided with groove, and groove matches with the chimb of described wear-resistant sleeve first inner side end; The abrading-ball body that described wear-resistant sleeve first and described wear-resistant sleeve second parcel equate with semi-round ball number of cavities inside wear-resistant sleeve first or second.
The beneficial effects of the utility model are: product structure is simple, novel unique, enhances productivity significantly, greatly reduces production costs.
