Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The cone crusher according to the present invention relates to a cone crusher for producing sand by re-crushing a crushed stone in a certain range of sizes.

The cone crusher is made by crushing pure aluminum aggregate having a size of 6 to 40 mm, which has been introduced into the cone cushion 100 by using an impact force and a compressive force due to the interaction between the cone cave 100 and the mantle 200, A conventional method of crushing the aggregate filled between the cone cave 100 and the mantle 200 by eccentrically rotating the mantle 200 located below the cone cave 100 is used, Which is different from a well-known technique in the structure of each of the magnet 100 and the mantle 200.

1 and 2, the cone crusher according to the present invention includes a cone cave 100 having a hollow formed therein, which extends from the top to the bottom.

The upper end of the cone cave 100 can be poured into the hollow interior of the pure aggregate, which has been crushed to a predetermined size by a pre-process, And the lower end is opened to allow the sand to be discharged to the outside. As described above, the inner hollow extends from the upper part to the lower part as described above, and the inner surface A plurality of vertical portions and inclined portions are formed.

Specifically, the cone cave 100 includes a first vertical part 110 forming an inlet, which is a passage through which the pure algae material is injected into the hollow, and a second vertical part 110 extending in the first vertical part 110 A second vertical portion 130 having a vertical inclination and a second inclined portion 120 having a slope of 35 degrees with respect to the second vertical portion 130, A third inclined portion 160 continuous from the second inclined portion 140 and inclined at 38 degrees with respect to the second vertical portion 130; And a fourth inclined portion 170 continuous from the first vertical portion 160 and having an inclination of 48 ° with respect to the second vertical portion 130.

The first vertical portion 110 may have a structure in which the inner hollow area of the cone cube 100 is not expanded or reduced but remains the same in a certain range, The area of the inner hollow of the cone 100 is extended to a certain extent downward and the area of the inner hollow of the cone 100 is not expanded or reduced by the second vertical portion 130 and is maintained in a constant range, The inner hollow area of the cone cave 100 is gradually expanded downward by the second inclined portion 140, the third inclined portion 160, and the fourth inclined portion 170.

1 and 3, the cone crusher according to the present invention is eccentrically rotated by a rotating shaft installed inside the cone crusher, and is inserted into the inner hollow of the cone cave 100, (200).

4 is an exemplary view showing a mantle inserted into an inner hollow of a cone of a cone crusher according to the present invention.

The upper and lower ends of the mantle 200 are coupled to the rotating shaft passing through the upper and lower ends of the mantle 200, so that all the outer surfaces of the mantle 200 are separated from all the inner surfaces of the cone 100 by a predetermined distance. (100), which is eccentrically rotated by a rotating shaft that is eccentrically rotated, and re-crushes pure algae charged through the inlet by interaction with the cone (100), and discharges it to the outside.

Specifically, the mantle 200 has a lower end area wider than an upper end area. The upper end of the mantle 200 has a plurality of inclined surfaces inclined downward from the upper end to the lower end. And a right-angled rectangular protrusion 210 is formed.

5, the first inclined portion 120, the second vertical portion 130, the second inclined portion 140, and the third inclined portion 140, which are sequentially formed on the side surface of the cone cave 100, The gap between the cone cave 100 and the mantle 200 is widened by the rectangular portion 160 and the fourth inclined portion 170 and the rectangular protrusion 210 formed on the side surface of the mantle 200 and the plurality of inclined surfaces So that the pure algae are compressed and crushed while being compressed when the distance between the cone cave 100 and the mantle 200 is narrowed, thereby inducing a repetitive action of descending when the interval is widened.

At this time, the gap between the cone cave 100 and the mantle 200 is not always kept fixed. As the mantle 200 is eccentrically rotated, the gap is continuously changed, Promote the yam and descent.

The rectangular protrusion 210 is a component that impacts pure algae when the mantle 200 is eccentrically rotated. The rectangular protrusion 210 is formed on one side of the side surface of the mantle 200, And at the same time, all or a part of the pure aggregate is crushed.

In other words, if the shape of the sand added to the concrete is not excellent, the frictional force between the sand increases, which affects the workability, fluidity and filling of the concrete, so that the shape of the sand to be added to the concrete is preferably circular or cubic , The present invention realizes the above effect by crushing all or a part of the pure algae material by the right-angled protrusion 210.

At this time, an inclined protrusion 150 corresponding to the right-angled protrusion 210 is formed on the inner side surface of the cone 100 by the second vertical part 130 and the second inclined part 140, The gap between the cave 100 and the mantle 200 is narrowed, and at the same time, all or a part of the pure aggregate is crushed.

That is, the right-angled protrusion 210 and the inclined protrusion 150 are positioned adjacent to each other to narrow the gap between the cone cave 100 and the mantle 200, and at the same time, Have the same function.

The aggregate in which all or part of the aggregate is crushed by the right and left protrusions 210 and 150 is moved downward along the gap between the cone 100 and the mantle 200, And a second inclined portion 140 continuous from the second inclined portion 140 and having an inclination angle of 38 degrees with respect to the second vertical portion 130, The gap is temporarily narrowed by the contact portion of the third inclined portion 160 where the inclination is formed and the gap is temporarily reduced by at least one of the plurality of inclined surfaces formed on the side surface of the mantle 200 The pure alumi aggregate in which all or a part of the aggregate is crushed is crushed and crushed, and then the raw aggregate becomes sand.

Thereafter, the gap is again widened by at least one of the inclined surfaces formed on the third inclined portion 160 and the fourth inclined portion 170 of the cone cave 100 and the side surface of the mantle 200 So that the produced sand is easily discharged to the outside.

The mantle 200 and the mantle 200 have a height difference of 185 to 195 mm between the upper end of the cone cave 100 and the upper end of the mantle 200 when the mantle 200 is installed inside the cone crusher, ) Is set to 190 to 200 mm.

Since the cone crusher according to the present invention has the purpose of producing sand of various sizes by re-crushing the crushed pure aggregate material having a size of 6 to 40 mm, the length of the horizontal portion of the right- And the interval between the cone cave 100 and the mantle 200 which is narrowed by the slant projection 150 and the right-angled protrusion 210 is 90 mm and the length of the vertical part is 25 mm to 35 mm. And may be configured to have a contact point between the second inclined portion 140 and the third inclined portion 160 of the cone cave 100 and a plurality of inclined surfaces formed on the side surface of the mantle 200, And the minimum range of the interval narrowed by the inclined surfaces is 32 to 37 mm.

The gap between the cone cave 100 and the mantle 200 described above is an interval in which the mantle 200 is not rotated. When the pure algae material is refracted, the mantle 200 is eccentrically rotated, The gap can be further reduced to a maximum of 20 mm so that the interval between the cone 100 and the mantle 200 narrowed by the inclined protrusion 150 and the right protrusion 210 can be narrowed to a maximum of 70 mm, A concave cove 100 that is narrowed by at least one of inclined surfaces formed at a contact point between the second inclined portion 140 and the third inclined portion 160 of the cone cave 100 and a plurality of inclined surfaces formed at a side surface of the mantle 200 ) And the mantle 200 can be narrowed to a maximum of 12 mm.
