Description

Abrasive body

Technical field

The utility model is related to a kind of abrasive body, its be used for various materials (such as cement, coal, ore, construction material, Rubbish and other materials) it is ground.

Background technology

Known metal and non-metal grinding material has spherical form.In addition, the also abrasive body of other forms, such as The combination of cube, disk, taperer and various three-dimensional shapes.

Date of application describes a kind of abrasive body for the BG1359U documents on June 16th, 2010, and it has close to class Spherical tetrahedral form, it is made up of four same sections to link into an integrated entity, and is pushed up formed with six edges and four Point.In some variations, these edges for rounding or it is flat inclined, these summits for rounding or one in them It is individual or multiple also flat inclined.

Utility model content

The purpose of this utility model is to provide a kind of abrasive body, and it can be used in various materials (such as cement, coal, ore deposit Stone, construction material, rubbish and other materials) it is ground.

The utility model provides a kind of abrasive body, and it has close to spherical tetrahedral form, wherein four summits Formed by the part of spheroid, the region of six roundings is formed in institute between four summits and four spherical arms Six edges stated between arm are rounding, and the region of six roundings is formed by six edges of rounding , and each of region of six roundings is in the shape reduced from both ends to center section.

Wherein, formed by three summits and along three arms with the roundabout ring close to the section of semicircle.

In a word, the utility model provide it is a kind of have close to spherical tetrahedral geometry abrasive body, its by this as Four identical arms of the part of spheroid are formed, and summit is the part of spheroid (its diameter is less than the diameter of spherical arm), between arm Edge is rounding, and spherical arm is connected with spherical summit by the surface of rounding, so that in the body newly formed It is cut in the spherical tetrahedron of preferable geometry, and each in three parts is gradually transitions two other.Such shape Into abrasive body there are spherical tetrahedral all feature and advantage, here it is：Have compared to those spherical grinding bodies Bigger surface, ball arrange have and be used to carry out high speed powder to the larger particles material to be ground more to high-density Broken edge simultaneously has spherical summit, and these are the prerequisites of mill shell fanout free region.Because cement is in higher temperature Under be ground, this can cause the rapid abrasion and loss of expensive shell, therefore, the abrasive body proposed is applied to cement first Grinding.The grinding for being additionally, since cement is carried out in water-less environment is dried, and the edge of the abrasive body proposed will be used for The self-cleaning of abrasive body, to remove the fine particle for the institute's grinding-material being bonded on their arm.Now, spherical grinding is removed The fine particle of the adhesive surface of body is carried out by means of the help of special chemical product, and such cleaning delays cement life Produce and add the cost of manufacture of cement.The form of the abrasive body proposed is applied to a large amount of lifes by casting and edging Production.In other modification, abrasive body is formed through its three spherical summits and along the roundabout of three spherical arms Ring.It is roundabout by the press forging by means of automatic forging press because metal unnecessary on steel billet can flow out and form the roundabout ring Ring allow largely to produce this abrasive body.Both modifications proposed are applied to by metal and metal alloy and non-metallic material Material and combinations thereof finely manufacture abrasive body.

Brief description of the drawings

The utility model is shown by accompanying drawing appended below.

Fig. 1 is the front view of proposed abrasive body；

Fig. 2 is the top view of the abrasive body proposed shown in Fig. 1；

Fig. 3 presents the А-А parts of the abrasive body shown in Fig. 1；

Fig. 4 is the front view of the abrasive body with roundabout ring proposed；

Fig. 5 is the top view of the abrasive body with roundabout ring proposed.

Embodiment

The utility model is more fully hereinafter illustrated by Fig. 1 and Fig. 2, wherein accompanying drawing show arm 3, summit 2 and Region 1, the arm 3 are the part of spheroid, and the summit 2 is the part of the spheroid sphere diameter of arm 3 (its diameter be less than), the region 1 Connect the spheroid on the summit 2 and the spheroid of the arm 3.The edge 4 of rounding is located between these arms 3.In a word, abrasive body has four 4, the four spherical summits 2 in edge of spherical 3, six roundings of arm of identical and the surface 1 of six roundings (are used to connect summit 2 With arm 3).Fig. 3 presents the А-А parts of the abrasive body shown in Fig. 1, and the wherein edge 4 of arm 3 and rounding is labeled.Can be with Rounding is carried out along circular arc or along the protrusion arc of another geometrical curve.The region 1 of six roundings is by rounding Six edges 4 and formed, and each of region 1 of six roundings is in shape from both ends to center section that reduce from.

The front view of the modification of the abrasive body shown in Fig. 1 and Fig. 2 is given in Fig. 4.It is included through three summits 2 simultaneously Along the roundabout ring 5 of three arms 3.The shape in the section of ring 5 is similar to semicircle.The top view of abrasive body modification in Fig. 4 exists Provided in Fig. 5, wherein arm 3 and roundabout ring 5 are labeled.

Application of the present utility model

Abrasive body is used to crushing and grinding multiple material.Compared to this kind of abrasive body being currently known, edge carries The high crushing to material, while the material granule for the crushing for feeding grinding machine is ground by their spherical arm.Compared to class As ball diameter, under equal volume and quality, the bigger diameter of the spherical arm can realize grinding technique Improvement, it is advantageously reflected in the quality for the material to be ground.Since it, which is high quality manufacture of cement, creates prerequisite bar Part, this just have found concrete application in cement.The abrasive body is initially used for going barrel ball mill, it may also be used for other knots In the grinding machine of structure, such as vertical-type, oscillating mode or other types.By using for producing skill known to known abrasive body Art, the abrasive body proposed are fabricated to various materials meticulously.This means their price be similar to have now known grind The price of mill body.Their use is not required to special vocational training for the workers and staff or converts grinding machine equipment used.
