Abstract

A powerful grinding ball is characterized in that a plurality of groups of circular hole grooves are uniformly designed on the surface of a grinding ball body, conical grinding teeth are arranged in the hole grooves, the powerful grinding ball is used in a rough grinding section of a ball mill, a meshing rolling cutting edge is generated for coarse grinding materials to shear and enhance crushing strength, the coarse grinding materials are rapidly cracked, and the rough grinding materials enter a grinding material fine grinding section through coarse and fine grinding material fence grids in the ball mill, so that the effects are improved, energy is saved, and the environment is protected. The design and manufacture of the sphere mold are simple, the sphere pressing mold is easy to operate, and the demolding is convenient after the sphere is molded. The edge of the circular hole slot and the edge of the ball surface body form a large-angle shearing effect. And because the round hole groove designed on the surface body of the strong grinding ball has a moderate caliber, the mutual meshing abrasion between the balls is effectively delayed, and the service life of the strong grinding ball is prolonged.

Description

Strong grinding ball

Technical Field

The utility model relates to a metal or nonmetal grinding ball that is used for ball-mill built-in to use, concretely relates to a powerful grinding ball that is used for the interior corase grind district section of ball-mill to use to coarser grinding material.

Background

At present, metal or nonmetal grinding balls used in a ball mill have smooth surfaces and poor relative friction force, and particularly when the metal or nonmetal grinding balls are used in a rough grinding section of the ball mill, the metal or nonmetal grinding balls are small in friction force during rolling operation with a coarse grinding material, so that the metal or nonmetal grinding balls are time-consuming, power-consuming, low in working efficiency and not beneficial to energy conservation and environmental protection. In the prior art, a mode of manufacturing a blind hole on a grinding ball body and then fixing a grinding nail in the blind hole is adopted, and although the friction force is increased, the grinding ball has small crushing force on harder materials and larger abrasion due to smooth surface.

Disclosure of Invention

To above not enough, the utility model provides a pair of powerful grinding ball is applicable to and grinds the use of quick-witted corase grind district section.

The utility model discloses a powerful grinding ball, including the grinding ball body, characterized by grinding ball body surface evenly distributed has shallow hole groove, the bore in shallow hole groove is 1/12-1/6 of the outer periphery of grinding ball body, the hole depth in shallow hole groove is 1/12-1/6 of grinding ball body diameter, the shallow hole inslot have the grinding tooth.

The strong grinding ball is characterized in that the shallow hole grooves are circular shallow hole grooves, and the number of the circular shallow hole grooves is six and the circular shallow hole grooves are uniformly distributed on the outer surface of the grinding ball.

The powerful grinding ball is characterized in that the grinding teeth are conical grinding teeth, and the height of the conical grinding teeth is the same as the depth of a shallow hole groove.

The strong grinding ball is characterized in that the conical grinding teeth are truncated cone-shaped or truncated pyramid-shaped grinding teeth.

The utility model discloses a powerful grinding ball evenly designs the circular hole groove of multiunit and sets up the taper in the hole groove and grinds the tooth in grinding ball body surface, is used in the coarse grinding district section in the ball-mill, produces the interlock to grinding the broken dynamics of blade shearing reinforcing to the coarse grinding material for coarse grinding material is cracked rapidly, and gets into the abrasive material fine grinding district section through coarse, fine grinding material fence net in the ball-mill, improves the energy-concerving and environment-protective of efficiency.

Drawings

FIG. 1 is a schematic diagram of a power grinding ball structure;

in the figure, 1-the body of the grinding ball; 2-shallow hole groove; 3-grinding the teeth.

Detailed Description

Referring to the attached drawing 1, a powerful grinding ball, including grinding ball body 1, evenly set up the shallow hole groove 2 of the circular or square or ellipse of a plurality of or rectangle isopipe on this grinding ball body surface, the degree of depth and the aperture in shallow hole groove do the twelfth to sixth of the outer periphery of grinding ball body is provided with grinding teeth 3 in the shallow hole groove, and this grinding teeth's height is the same with the hole groove degree of depth, and the top of grinding teeth is together with the outer periphery of grinding ball body promptly. The grinding teeth may be in the shape of a truncated cone or a truncated pyramid, or may be in other shapes.

The utility model discloses a concrete example, design 6 circular shallow hole grooves 2 of group on grinding ball body 1, there is pyramid form grinding tooth at the inslot, shallow hole groove and pyramid form grinding tooth evenly distributed in it on the powerful grinding ball body, form the blade on the spheroid surface and cut, wherein the round hole bore in circular shallow hole groove is 6/1-12/1 of this spheroid girth, such design lies in the effectual mutual interlock that prevents between the grinding spheroid, cuts and cause wearing and tearing, extension powerful grinding ball life cycle. The top of the pyramid grinding tooth in the shallow hole is as high as the surface of the strong grinding ball, and the height is the same as the depth of the shallow hole groove, which is 6/1-10/1 of the diameter of the ball, forming a grinding tooth structure. The coarse abrasive in the coarse grinding section of the ball mill generates the meshing rolling shearing force. The design grinding tool is simple, the film pressing operation is convenient, and the demoulding is convenient and fast after the ball body is formed.

Roll over powerful grinding ball and can be by casting direct forming, if adopt the shell mould casting then can make production efficiency improve greatly.

The high-power grinding ball is used in the coarse grinding section of the ball mill, and generates the shearing force of the meshing and rolling cutting edge aiming at the coarse grinding materials, so that the effect is effectively improved. The coarse grinding materials are quickly crushed and enter a fine grinding section of the grinding machine through the fence grids, the quality is effectively improved, the yield is effectively increased, the design requirements are met, and the purposes of energy conservation and environmental protection are achieved.
