Description
Technical field
The present invention relates to wear-resistant ball technical field, particularly relate to a kind of complex abrasion-proof ball.
Background technology
Wear-resistant ball is a kind of for the crushing medium in ball mill, for the material in crushing mill, and Yi Zhongshi, being that the white cast-iron of main alloy element is called for short chrome alloy cast iron with chromium, is that the cast grinding ball of material is called chromium alloy iron casting abrading ball with chrome alloy cast iron; Another kind is, is that the cast grinding ball of material is called ductile iron abrading-ball with spheroidal graphite cast-iron, and the ductile iron abrading-ball of the matrix wherein obtained by heat treatment mainly bainite is called for short bainite ductile iron abrading-ball; The matrix obtained by heat treatment mainly martensitic ductile iron abrading-ball is called for short martensite nodular cast iron grinding ball.Wear-resistant ball is widely used in the industry ball mills such as metallurgical mine, cement building material, thermal power generation, flue gas desulfurization, magnetic material, chemical industry, water-coal-slurry, pellet, slag, superfine powder, flyash, calcium carbonate, quartz sand.
In Chinese Patent Application No.: disclose a kind of combination wear-resistant ball in 201220094493.6, it is characterized in that being combined by ball matrix and wear-resisting sphere, wear-resisting sphere is made up of two semi circular shells, and two semi circular shells joints are L-shaped, wrapped up by ball matrix by adhesive.Two semi circular shells linked together by means of only adhesive in this technical scheme, not firmly, two semi circular shells are easily separated, and this wear-resistant ball surface abrasion resistance effect is only desirable, haves much room for improvement.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of complex abrasion-proof ball, grinding effect is good.
A kind of complex abrasion-proof ball, comprise two hemispherical shells, this housing comprises hemispherical alloy wear-resisting layer, is provided with hemispherical steel layer inside this alloy wear-resisting layer; Alloy wear-resisting layer in a housing is provided with clamping block, and the alloy wear-resisting layer in another housing is provided with the buckling groove for accommodating clamping block;
The madial wall of this clamping block is provided with groove, and the steel layer be provided with in the housing of buckling groove is provided with through hole, and after clamping block is placed in buckling groove, this groove is communicated with through hole;
Wear-resistant ball also comprises the joint pin for embedding in groove and through hole; The diameter of joint pin can be a bit larger tham the diameter of through hole, allows joint pin and through hole interference fit, prevents joint pin landing.
Clamping block, buckling groove, joint pin is utilized to be linked together by two hemispherical shells, not easily separated; Wear-resistant ball is spherical, the probability rolled to any direction is the same, therefore, the degree of wear on alloy wear-resisting layer surface is substantially the same, both improves grinding effect like this, also extends service life, if wear-resistant ball is designed to oval grade for other shape, wear-resistant ball just can not roll with identical probability wantonly, and this just causes the degree of wear on alloy wear-resisting layer surface inconsistent, and service life is short.
Be provided with shot in the space formed between two steel layer, the volume of this shot is less than the spatial volume of two steel layer formation.
This joint pin is along the radial distribution of wear-resistant ball; Be convenient to like this utilize shot to pour in groove by joint pin, the length of joint pin is unsuitable long, prevents affecting shot and rolls.
First joint pin is inserted in through hole from inner side, when clamping block be placed in after buckling groove, two hemispherical shells link together time, now, groove is communicated with through hole, rock wear-resistant ball with strength, utilize the impulsive force of shot to pour in groove by joint pin, utilize joint pin, effectively avoid two hemispherical shells to be separated, increase service life.After alloy wear-resisting layer weares and teares completely, steel layer can be recycled, effectively provide cost savings.
Because the volume of shot is less than the spatial volume that two steel layer are formed, effectively like this to provide cost savings; Because shot density is large, in the process of grinding material, shot can impact steel layer, allows irregular, the aimless motion of wear-resistant ball, so just ensure grinding evenly, effective, and, the degree of wear on alloy wear-resisting layer surface is basically identical, reduces wear-resistant ball loss, extends service life.
Steel layer is provided with some skeletons, and this skeleton embeds in alloy wear-resisting layer away from one end of steel layer; Utilize skeleton to be convenient to steel layer and alloy wear-resisting layer to be fixed together, avoid mutual landing.
The region that this clamping block is positioned at groove is provided with runs through clamping block and the sight vane be communicated with groove; Utilize sight vane can get information about joint pin whether to have inserted in groove, avoid wear-resistant ball to occur substandard products like this.
The diameter of shot is 1:1.5-2 with the ratio of the internal diameter of steel layer; The words that the diameter of shot is excessive, be inconvenient to utilize shot to impact joint pin, the scroll zones of shot in the space that 2 steel layer are formed is large not, wear-resistant ball can not be allowed more arbitrarily to roll, the words that the diameter of shot is too small, the impulsive force of shot is little, and whole wear-resistant ball global density is not ideal enough, and grinding effect is bad.
This alloy wear-resisting layer surface is provided with some protrusion element, and this protrusion element comprises some arc convex, and the some arc convex in a protrusion element become circle distribution centered by the radial direction of wear-resistant ball.
By the design of projection, projection is allowed to be uniformly distributed centered by the radial direction of wear-resistant ball, no matter how roll, projection can both apply frictional force to material, projection in different protrusion element applies the active force of different directions to material, such grinding material is even, and grinding effect is good, the degree of protruding wearing and tearing is consistent, long service life.
This alloy wear-resisting layer surface is provided with at least 2 protrusion element, and this protrusion element comprises some rectangular preiections, the bearing of trend of the projection in a protrusion element and the bearing of trend oblique or vertical of the projection in another protrusion element.
By the design of projection, by arranging at least 2 protrusion element, no matter how roll, different protrusion element applies the frictional force of different directions to material, different protrusion element is different to the frictional strength of material, and such grinding material is even, and grinding effect is good, the degree of protruding wearing and tearing is basically identical, long service life; If the bearing of trend of protrusion element is consistent, the same to material active force like this, grinding effect is bad.
This protrusion element is interspersed; Increase grinding effect, allow different protrusion element share the active force of material to wear-resistant ball, improve service life.
In the present invention, clamping block, buckling groove, joint pin is utilized to be linked together by two hemispherical shells, not easily separated; Utilize shot, shot can impact steel layer, allows irregular, the aimless motion of wear-resistant ball, so just ensures that grinding evenly, effective; By the design of protrusion element, increase grinding effect; Structure of the present invention is simple, and cost is low.
