[0002] Construction aggregate refers to materials such as gravel and sand that are mixed with cement and water to form mortar or concrete, and the quality of these materials has a significant impact on the characteristics of the concrete.

[0003] While natural aggregates mined from rivers are ideal for construction, there are practical difficulties in securing them due to various regulations aimed at protecting nature and preventing ecosystem destruction caused by excessive extraction.

[0004] In particular, the extraction of natural aggregates such as river gravel and sand is legally prohibited, and crushed gravel or sea sand is currently used as a substitute.

[0005] For the reasons mentioned above, the method of producing aggregate by crushing rocks is widely used to resolve the shortage of natural aggregate supply.

[0006] When producing aggregate by crushing rocks, ensuring that the particle size of the final aggregate is uniform is a critical issue for its use after production.

[0007] If aggregate production is carried out using the above method, the quality of the aggregate produced may be degraded due to various foreign substances that may be introduced during the rock extraction process, and in such cases, it may become a factor that significantly reduces the overall strength when constructing concrete.

It includes a seventh moving member (150) for moving rocks and a foreign substance separation member (160) for separating foreign substances from crushed rocks moved by the seventh moving member (150).

[0037] In the aggregate production device system according to the present invention, the rock for producing aggregate is fed into the supply member (10).

[0038] The above supply member (10) is for supplying the rock to the first crushing member (20). It can be composed of a hopper.

[0039] The rock supplied through the supply member (10) is crushed by the first crushing member (20).

[0040] The first crushing member (20) above is configured to crush rocks into small pieces and, for example, can be configured as a jaw crusher.

[0041] The rock, finely crushed by the first crushing member (20), is moved to the first screen member (40) through the first moving member (30).

[0042] The remaining moving members, including the first moving member (30) mentioned above, may be configured to include a driving roller and a driven roller not shown and a conveyor belt placed between them, and the crushed rock is placed on the conveyor belt and moved.

[0043] The crushed rocks moved through the first moving member (30) are classified by size by the first screen member (40).

[0045] The above screen sections (401, 402, 403, 404, 405) may be composed of a metal mesh having a grid size according to the size of the aggregate to be sorted.

[0046] The crushed rocks classified by size by the first screen member (40) and the second screen member (90) can be moved to the next device through the moving member (B).

[0047] The first screen member (40) and the second screen member (90) can be modified according to the throughput of the entire device or the size and type of aggregate to be classified.

[0048] By sorting the aggregate according to size through the first screen member (40) above, it is configured to be separated into, for example, clay (B) having the smallest particle size, aggregate (A) having a size of approximately 40 mm, or aggregate having a particle size larger than 40 mm.

[0049] For example, among the aggregates selected by size by the first screen member (40), aggregates having a size of approximately 40 mm are configured to be moved to area A through the conveying member (42).

[0050] And, the crushed rocks classified into soil sizes by the first screen member (40) are configured to be moved to area B through the transport member (44).

[0051] The rocks classified by the first screen member (40) are moved to the moving member (52) by the second moving member (50).

[0052] In addition, an electromagnet sorting member (60) is disposed on the moving member (52), and the electromagnet sorting member (60) can be configured as a device that generates magnetic force by applying power.

[0053] The above-mentioned electromagnet sorting member (60) is configured to sort and remove magnetic materials from crushed rocks moved through the above-mentioned moving member (52).

[0054] The rock moved by the moving member (52) is fed into the first cone crushing member (70-1) included in the second crushing member (70).

[0055] Preferably, the second crushing member (70) includes a first cone crushing member (70-1) for crushing rocks transmitted from the second moving member (50) and the moving member (52), and a second cone crushing member (70-2, 70-3) for crushing rocks transmitted from the sixth moving member (140).

[0056] The above cone crushing members (70-1, 70-2, 70-3) are configured to crush rocks by applying pressure through the crushing cone (712) by introducing rocks into the crushing cone (712) which is positioned in the middle between the side walls (714).

[0057] The above cone crushing member (70-1, 70-2, 70-3) is configured to adjust the gap with the side walls (714) by moving the crushing cone (712) included therein in the up and down direction, thereby allowing the particle size of the crushed rock to be adjusted.

[0058] And, as illustrated in FIG. 4, for a pair of the second cone crushing members (70-2, 70-3), the rock moved by the sixth moving member (140) can be configured to be selectively distributed by a distribution device (142) and fed into the pair of the second cone crushing members (70-2, 70-3).

[0059] That is, the distribution device (142) is configured to be adjustable so that rocks are evenly distributed and fed into the pair of second cone crushing members (70-2, 70-3), or so that a larger amount of rocks is fed into one of the second cone crushing members (70-2, 70-3).

[0060] The rock crushed through the first cone crushing member (70-1) of the second crushing member (70) is transferred to the third moving member (80) through the moving member (72).

[0061] And, the crushed rock delivered to the third moving member (80) is fed into the second screen member (90).

[0062] As described above, the second screen member (90) may also be configured to include a plurality of screen sections (401, 402, 403, 404, 405) for classifying crushed rocks of different particle sizes, as a configuration for sorting crushed rocks according to size.

[0063] The rocks selected by the second screen member (90) can be moved upward or downward, that is, in both directions, by the fourth moving member (110).

[0064] The above-mentioned fourth moving member (110) may include a pair of moving members (110a, 110b) that move in both upward and downward directions and a moving member (110c) that moves upward.

[0065] The rocks classified by the second screen member (90) are moved upward or downward by the fourth moving member (110) and then transferred to the seventh moving member (150).

[0066] Through the uppermost 7th moving member (150-3) of the above 7th moving member (150), aggregate with a diameter of approximately 25 mm is moved to area D.

[0067] And, through the middle 7th moving member (150-2) of the 7th moving member (150) above, the stone powder is moved to area E.

[0068] And, through the lowest 7th moving member (150-1), aggregate with a diameter of approximately 40 mm can be moved to area C.

[0069] The rock moved upward by the fourth moving member (110) is moved by the sixth moving member (140) to the second crushing cone member (70-2) and the third crushing cone member (70-3) of the second crushing member (70).

[0070] And, the rock moved by the sixth moving member (140) is selectively distributed by the distribution device (142) and distributed to the pair of second cone crushing members (712, 714) and fed.

[0071] In addition, the rock moved downward by the fourth moving member (110) is moved to the third crushing member (130) through the fifth moving member (120).

[0072] And, the third crushing member (130) is configured to be a high-speed cone crushing member in which the cone crushing part rotates at high speed, so as to be configured to crush the rock being fed in at high speed.

[0073] An example of a procedure for producing aggregate through various members as described above is as follows.

[0074] First, when producing aggregate mainly with a diameter of 25 mm, aggregate with a diameter of approximately 25 mm is discharged from the second screen member (90) to the moving member (110a), aggregate with a diameter of approximately 40 mm is discharged to the moving member (110b), and aggregate with a diameter of approximately 40 mm or more is discharged to the moving member (110c).

[0075] If the quality of the 25mm diameter aggregate is good, the aggregate is moved upward through the moving member (110a) and transferred to the 7th moving member (150-3) to be transported to area D.

[0076] And, if the quality of the aggregate is poor, the aggregate is transported downward to the fifth moving member (120) and then transferred to the third crushing member (130).

[0077] The moving member (110b) transports 40 mm aggregate upward, and the moving member (110c) transports rocks larger than 40 mm upward and transfers them to the second crushing cone member (70-2, 70-3) through the sixth moving member (140).

[0078] And, mainly when producing aggregate with a diameter of 40 mm, aggregate with a diameter of 25 mm is discharged from the second screen member (90) to the moving member (110a), aggregate with a diameter of 40 mm is discharged to the moving member (110b), and rocks of 40 mm or more are discharged to the moving member (110c).

[0079] The moving member (110a) transfers a diameter 25 mm aggregate to the 7th moving member (150-3) and transports it to area D.

[0080] Additionally, the moving member (110b) conveys a 40 mm diameter aggregate downward and conveys it to area C through the 7th moving member (150-1).

[0081] The moving member (110c) moves rocks with a diameter of 40 mm or more upward and transfers them to the second crushing cone member (70-2) and the third crushing cone member (70-3) through the sixth moving member (140).

[0082] And, when producing low-quality aggregate with a diameter of approximately 40 mm, first, the rock fed through the supply member (10) is crushed by the first crushing member (20) and moved to the first screen member (40) through the first moving member (30).

[0083] And, the aggregate classified into 40 mm diameters by the first screen member (40) is moved to area A by the moving member (42).

[0084] And, when producing aggregate with a diameter of approximately 25 mm or 40 mm, the process of the rock fed through the supply member (10) being crushed by the first crushing member (20) and moving to the first screen member (40) through the first moving member (30) and being classified is the same.

[0085] Then, rocks with a diameter larger than 40 mm and crushed rocks with a diameter of approximately 40 mm are transported upward by the second moving member (50) and then crushed by the first cone crushing member (70-1).

[0086] And, it is fed into the second screen member (90) by the moving member (72) and the third moving member (80).

[0087] In addition, aggregate classified into diameters of approximately 24 mm by the second screen member (90) is moved to area D through the uppermost seventh moving member (150-3).

[0088] And, aggregate classified into diameters of approximately 40 mm by the second screen member (90) is moved to area C through the seventh moving member (150-1) at the very bottom.

[0089] In addition, if the diameter is larger than 40 mm, it is moved upward by the fourth moving member (110) and distributed and fed into the second cone crushing member (70-2) or the third cone crushing member (70-3) through the sixth moving member (140).

[0090] Thus, the aggregate re-crushed by the second cone crushing member (70-2) or the third cone crushing member (70-3) is configured to repeat the process of being re-feeded to the second screen member (90) through the moving member (72) and the third moving member (80).

[0091] And, when producing high-quality aggregate with a diameter of approximately 25 mm, the process in which the rock fed through the supply member (10) is crushed by the first crushing member (20) and moved to the first screen member (40) through the first moving member (30) for classification is the same.

[0092] Afterwards, the crushed rock is moved upward through the second moving member (50), and the rock with a diameter larger than 40 mm and the crushed rock with a diameter of around 40 mm are transported by the moving member (52) and then crushed by the first cone crushing member (70-1).

[0093] Then, after being fed into the second screen member (90) by the moving member (72) and the third moving member (80), crushed rock with a diameter of approximately 40 mm is selectively fed into the second cone crushing member (70-2) or the third cone crushing member (70-3) through the fourth moving member (110) and the sixth moving member (140).

[0094] At this time, the gap of the cone crushing section (712, 714) included in one or more of the second cone crushing member (70-2) or the third cone crushing member (70-3) is configured to crush the rock in a state adjusted to produce aggregate of approximately 25 mm.

[0095] And, the rock crushed by the second cone crushing member (70-2) or the third cone crushing member (70-3) is fed back into the second screen member (90) and the process of classification is repeated.

[0096] In addition, in the case of low-quality aggregate or wind stone, only stone powder of 15 mm or less is produced, and the process in which the rock fed through the supply member (10) is crushed by the first crushing member (20) and moved to the first screen member (40) through the first moving member (30) and classified is the same.

[0097] Afterwards, the crushed rock is moved upward through the second moving member (50), and the rock with a diameter larger than 40 mm and the crushed rock with a diameter of approximately 40 mm are transported to the first cone crushing member (70-1) by the moving member (52) and crushed.

[0098] Then, after being fed into the second screen member (90) by the moving member (72) and the third moving member (80), the stone powder is moved to area E through the intermediate seventh moving member (150-2).

[0099] And, the remaining crushed rock is moved downward through the fourth moving member (110), transferred to the fifth moving member (120), and then fed into the third crushing member (130).

[0100] And, the rock crushed at high speed by the third crushing member (130) is fed again into the second screen member (90) through the moving member (74) and the third moving member (80).

[0101] And, the stone powder classified by the second screen member (90) is moved to the area E, and the remaining crushed rock is fed into the third crushing member (130), and the process is repeated.

[0102] By configuring the above third crushing member (130) as a high-speed cone crushing member, it is configured to be able to produce low-quality aggregate or wind stone efficiently in a short period of time.

[0103] Meanwhile, a foreign matter separation member (160) is provided to separate foreign matter from crushed rocks moved by the 7th moving member (150).

[0104] The above foreign substance separation member (160) may include an input tank (162) for inputting crushed rocks moved by the seventh moving member (150), a collision plate member (164) that collides with the moving crushed rocks, an air injection member (166) for applying pressure to the foreign substances to move them, a foreign substance sorting screen member (167) positioned below the collision plate member (164) and the air injection member (166), and an eighth moving member (168) for moving the crushed rocks.

[0105] The above-mentioned input tank (162) is formed as a structure in the shape of a cylinder or a cuboid, configured so that crushed rocks can be fed into it.

[0106] A collision plate member (164) is disposed on the upper part of the above-mentioned input tank (162) to move by colliding with crushed rocks that are moved and input by the 7th moving member (150).

[0107] As shown in FIG. 6, the impact plate member (164) is positioned at an angle inside the input tank (162) so that crushed rocks collide with the impact plate member (164) and gradually fall downward due to their own weight.

[0108] The above collision plate members (164) are arranged in pairs (164-1, 164-2) facing each other inside the input tank (162).

[0109] As shown in FIG. 7, the collision plate member (164) may be configured to have collision protrusions (1642) formed thereon so that crushed rocks collide with the collision protrusions (1642) as they are moved downward by the collision plate member (164).

[0110] And, an air injection member (166-1, 166-2) is disposed at the bottom of the collision plate member (164) to apply pressure to and move foreign substances that are scattered during the process of crushed rocks colliding with the collision plate members (164-1, 164-2).

[0111] Here, the air injection member (166-1) positioned at the top is positioned between a pair of collision plate members (164-1, 164-2) positioned adjacently above and below, and the air injection member (166-2) positioned at the bottom is positioned between the collision plate member (164-2) and the foreign substance line edge screen member (167).

[0112] In addition, foreign matter discharge sections (163-1, 163-2) for discharging foreign matter to the outside may be formed on the side of the input tank (162) facing the air injection members (164).

[0113] Thus, it is configured so that foreign substances such as dust, vinyl, or wood powder can be discharged to the foreign substance discharge section (163-1, 163-2) by the air pressure sprayed through the air injection member (164).

[0114] And, a foreign matter screening screen member (167) is disposed below the collision plate member (164) and the air injection member (166).

[0116] And, foreign substances falling onto the sorting screen (1672) are moved to the outside of the input tank (162) by the operation of the drive roller (1674) and are configured to be moved and removed by the air pressure sprayed from the air injection member (1676).

[0117] And, an eighth moving member (168) for moving crushed rocks is disposed at the lower part of the above foreign matter line screen member (167).

[0118] Through the above eighth moving member (168), aggregate of a predetermined diameter that is the target object can be moved to the outside of the input tank (162) and collected.

[0119] Meanwhile, in another embodiment of the present invention illustrated in FIG. 8, a blower member (161) for applying downward air pressure is disposed at the upper part inside the input tank (162).

[0120] Thus, it is configured so that foreign substances, such as dust generated during the process of crushed rocks being fed into the input tank (162) colliding with the impact plate member (164), can be scattered more smoothly.

[0121] And, a water spray member (170) is disposed in the foreign matter discharge section (163-1, 163-2) outside the input tank (162).

[0122] As illustrated in FIG. 9, the water spraying member (170) may include a water supply pipe (172) and a scattering member (174) for scattering water falling from the water supply pipe (172).

[0123] Here, the scattering tip (176) formed at the lower part of the scattering member (174) is formed in a "U" shape, and its end (177) can be positioned to contact the opening (173) at the lower part of the opening (173) of the water supply pipe (172).

[0124] Thus, the water discharged into the water supply pipe (172) through the scattering tip (176) is broken into small pieces and falls downward.

[0125] The above water spray member (170) may be configured to be coupled to a foreign matter blocking member (171) to spray water downward, and the above water spray member (170) is installed at a location where a lot of dust and foreign matter are scattered, so that by spraying water on the dust and foreign matter, they can fall into the foreign matter collection unit (1632, 1634).

[0126] The foreign substances such as dust are configured to fall into the foreign substance collection unit (1632, 1634) and be collected without being scattered far to the outside through the foreign substance blocking member (171), the water spraying member (170), and the foreign substance collection unit (1632, 1634).

[0127] If a configuration for supplying finely broken water is installed inside the opening (173) of the water supply pipe (172), dust and foreign substances entering the opening (173) may get stuck in the space between the configuration for supplying finely broken water and the opening (173), thereby closing the opening (173), or in the case of winter, the water may solidify in the space, thereby closing the opening (173).

[0128] To prevent this phenomenon, the scattering tip (177) is positioned close to the opening (173) of the water supply pipe (172), thereby maximizing the cross-sectional area of ​​the opening (173), which is the water flow passage, while also allowing the water to be broken into small pieces and supplied.

[0129] The above scatter tip (177) is formed with a circular cross-section, but its end may be formed pointed or flat as shown in FIG. 10.

[0130] As described above, when the end (177) of the scattering tip (176) is formed to be pointed, the space between the end of the scattering tip (177) and the opening (173) can be secured to be wider and larger, thereby preventing dust and foreign matter from getting stuck between the end (177) of the scattering tip (176) and the lower part of the opening (173).

[0131] And, as shown in FIG. 10, if the end (177) of the scatter tip (176) is formed flat, water can be sprayed over a wider range.

[0132] In the above scatter tip (176), a plurality of concave portions (1762) formed in the height direction may be formed at predetermined intervals along the circumferential direction.

[0133] The space between the scatter tip end (177) and the water supply pipe opening (173) can be made slightly larger by the above-mentioned concave portion (1762), and the water discharged through the water supply pipe opening (173) can be supplied uniformly along the circumferential direction of the scatter tip (176) without being biased to one side.

[0135] For the above, the terms used in the embodiments of the present invention have the same meaning as generally understood by those skilled in the art to which the present invention pertains.

[0136] Although the present invention has been described by limited embodiments and drawings, the above embodiments are intended to explain, not to limit, the technical concept of the present invention, and therefore the technical concept of the present invention is not limited to these, and various modifications and variations may be made by a person skilled in the art within the scope of the technical concept of the present invention and the equivalent scope of the following claims.

[0137] Accordingly, the scope of protection of the present invention shall be interpreted by the claims, and all technical ideas within an equivalent scope shall be interpreted as being included within the scope of rights of the present invention.

[0138] In addition, within the scope of the purpose of the present invention, one or more of the components may be optionally combined.

[0139] The terms "included" or "composed" mentioned above mean that the relevant component may be included, and should be interpreted as meaning that other components may additionally be included. Explanation of the symbols
