Embodiment 1

[0035] Embodiment 1, combining image 3 :

[0036] The surface of the alloy wear-resistant layer 1 is provided with several protruding units, the protruding unit includes several arc-shaped protrusions 10, and the several arc-shaped protrusions 10 in one protruding unit are distributed in a circle around the radial direction of the wear-resistant ball .

[0037] Through the design of the protrusions 10, the protrusions 10 are evenly distributed around the radial direction of the wear-resistant ball. No matter how they roll, the protrusions 10 can exert friction on the material, and the protrusions 10 in different protrusion units exert friction on the material. Forces in different directions, so that the grinding material is uniform, the grinding effect is good, the degree of wear of the protrusions 10 is consistent, and the service life is long.

Embodiment 2

[0038] Example 2, combined with Figure 4 :

[0039]The surface of the alloy wear-resistant layer 1 is provided with at least two protruding units, and the protruding units include several rectangular protuberances 12, and the extending direction of the protruding 12 in one protruding unit is different from the protruding 12 in the other The direction of extension is oblique or vertical.

[0040] Through the design of the protrusion 12, by setting at least 2 protrusion units, no matter how they roll, different protrusion units exert friction in different directions on the material, and the friction strength of different protrusion units on the material is different, so that the grinding material is uniform and the grinding The effect is good, the degree of wear of the protrusions 12 is basically the same, and the service life is long; if the extension directions of the protrusion units are consistent, the force on the material is the same, and the grinding effect is not good....

Abstract

The invention discloses a combined grinding ball. The combined grinding ball comprises two hemispherical shells. Each shell comprises a hemispherical alloy abrasion-resistant layer. A hemispherical steel layer is arranged on the inner side of each alloy abrasion-resistant layer. A first extension layer is arranged on the edge of the alloy abrasion-resistant layer in one shell, and a second extension layer is arranged on the edge of the steel layer in the other shell. A first thread is arranged on the first extension layer, and a second thread engaged with the first thread is arranged on the second extension layer. According to the combined grinding ball, the two hemispherical shells are connected through the first thread, the second thread and connecting columns, and thus the two hemispherical shells cannot be separated easily; a lead ball is adopted and can impact the steel layers, so that the grinding ball is made to move irregularly and aimlessly, and accordingly uniform grinding is guaranteed, and the effect is good; through the design of protrusion units, the grinding effect is improved; and the combined grinding ball is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of wear-resistant balls, in particular to a combined wear-resistant ball. Background technique [0002] Wear-resistant ball is a kind of crushing medium used in ball mills to crush the materials in the mill. One is white cast iron with chromium as the main alloying element, referred to as chromium alloy cast iron, and the casting of chromium alloy cast iron as material The grinding ball is called chromium alloy cast iron grinding ball; the other is that the casting grinding ball made of ductile iron is called ductile iron grinding ball, and the matrix structure obtained by heat treatment is mainly bainite. Martensitic ductile iron grinding ball; the matrix structure obtained by heat treatment is mainly martensitic ductile iron grinding ball, referred to as martensitic ductile iron grinding ball. Wear-resistant balls are widely used in ball mills in metallurgical mines, cement building materials, thermal pow...
