본 발명은 골재 입도 분포 조절방법 및 장치에 관한 것으로, 더욱 상세하게는 파쇄기에 의해 파쇄된 후 스크린에 의해 입도 별로 분리선별된 골재를 사용목적에 맞는 입도 분포를 갖도록 혼합하여 생산할 수 있는 골재 입도 분포 조절방법 및 장치에 관한 것이다.The present invention relates to a method and apparatus for controlling aggregate particle size distribution, and more particularly, aggregate particle size distribution that can be produced by mixing aggregated aggregates separated by particle size by screening to have a particle size distribution suitable for the purpose of use. It relates to a control method and apparatus.

일반적으로, 석산 골재 및 재생골재 생산에 사용하는 설비는 크게 골재를 일정 입도 이하로 파쇄하는 파쇄기와, 골재를 입도 별로 분리선별하는 골재 선별장치와, 이물질을 분리하기 위한 이물질분리장치로 구성되어 이물질이 제거된 양질의 골재를 생산하고 있다.In general, the equipment used for the production of masonry aggregates and recycled aggregates is composed of a crusher for crushing aggregates to a predetermined particle size or less, an aggregate sorting device for separating aggregates by particle size, and a foreign matter separating device for separating foreign matters. This produces good quality aggregates that have been removed.

그러나, 종래의 설비를 이용하여 골재를 생산할 경우 골재 입도 분포량을 조절할 수 없어 특정 입도의 골재가 부족하거나 반대로 과다할 수 있는 문제점이 있었다.However, when the aggregate is produced using conventional equipment, the aggregate particle size distribution amount cannot be adjusted, and there is a problem in that aggregates having a specific particle size are insufficient or vice versa.

즉, 특정 입도의 골재가 과도하게 남거나 부족하게 될 경우 불필요하게 골재를 쌓아두어야 하므로 이를 쌓기 위한 추가적인 공간이 필요하게 되며, 아울러 쌓아둔 골재는 단순 매립에 사용하거나 노반재용 등과 같이 저급한 용도로만 사용할 수밖에 없어 재생골재의 생산에 따른 생산성이 저하되는 문제점으로 이어지고 있었다.In other words, if aggregates of a certain particle size are excessively left or insufficient, the aggregates need to be piled up unnecessarily, and thus additional space is required for stacking the aggregates. There was no problem leading to a decrease in productivity due to the production of recycled aggregate.

이를 보완하기 위해 각각의 입도에 따라 생산된 골재를 페루로더 등과 같은 별도의 혼합설비를 이용하여 일정 비율로 혼합한 것이 제안되어 사용하고 있으나, 이는 적정 분포를 갖기도 어려울 뿐만 아니라 별도의 장비 사용에 의한 부가적인 비용이 발생할 수 있는 등의 문제점도 있었다.In order to compensate for this, it is proposed that the aggregate produced according to each particle size is mixed at a certain ratio by using a separate mixing facility such as a Peru loader, but this is not only difficult to have a proper distribution but also by using separate equipment. There were also problems such as additional costs may occur.

따라서, 본 발명은 상기와 같은 문제점을 해소하여 별도의 혼합설비를 갖추지 않고도 적정 입도 분포를 갖는 골재를 생산할 수 있도록 하는데 그 목적이 있다.Therefore, an object of the present invention is to solve the problems as described above to produce aggregate having an appropriate particle size distribution without having a separate mixing facility.

본 발명의 목적은, 특정 입도의 골재를 사용목적에 따라 조절하여 생산할 수 있도록 한 골재 입도 분포 조절방법을 제공하는 데 있다.It is an object of the present invention to provide a method for controlling aggregate particle size distribution, which enables the production of aggregates having a specific particle size according to the purpose of use.

본 발명의 다른 목적은, 재생골재를 자동으로 파쇄기에 재투입하여 적합한 입도 분포를 갖는 골재를 지속적으로 생산할 수 있도록 한 골재 입도 분포 조절장치를 제공하는 데 있다.Another object of the present invention is to provide an aggregate particle size distribution control device capable of continuously producing aggregate having a suitable particle size distribution by automatically reintroducing recycled aggregate into a crusher.

본 발명의 또 다른 목적은, 골재를 폐기처리하지 않고 재활용하여 폐기비용의 낭비를 줄이고, 아울러 경제적 효과도 동시에 누릴 수 있도록 한 골재 입도 분포 조절방법 및 장치를 제공하는 데 있다.Still another object of the present invention is to provide a method and apparatus for controlling aggregate particle size distribution, which can reduce waste of waste costs by recycling the aggregate without disposing of the aggregate, and at the same time enjoy economic effects.

혼합용 골재가 입도 별로 쌓이지 않도록 혼합하는 골재혼합단계와;An aggregate mixing step of mixing the aggregate so that the aggregate is not accumulated for each particle size;

재투입용 골재를 파쇄기로 재투입하는 골재재투입단계로 구성되어 달성된다.It is achieved by consisting of an aggregate input step of re-inserting the aggregate for re-feeding into the crusher.

한편, 본 발명을 달성하기 위한 골재 입도 분포 조절장치는 파쇄기에 의해 파쇄된 골재를 입도 별로 분류선별하기 위한 스크린의 출구에 설치되어 상기 스크린의 걸름망을 통과하지 못한 골재를 혼합용 골재와 재투입용 골재로 배분하는 분배기와;On the other hand, the aggregate particle size distribution control device for achieving the present invention is installed at the outlet of the screen for sorting the aggregates broken by the crusher for each particle size aggregate for re-injecting the aggregates that did not pass through the strainer of the screen A distributor for distributing to aggregate;

상기 분배기를 통하여 공급된 혼합용 골재가 입도 별로 쌓이지 않도록 포집하여 혼합하는 혼합기로 구성되어 달성된다.Mixing aggregate supplied through the distributor is achieved by consisting of a mixer to collect and mix so as not to accumulate by particle size.

따라서, 파쇄기에 의해 파쇄된 후 스크린에 의해 입도 별로 분리선별된 골재를 사용목적에 맞는 입도 분포를 갖도록 분배기를 통해 배분한 후 혼합기를 통하여 혼합하여 생산할 수 있게 되며, 아울러 외부로 배출되지 않은 골재는 파쇄기로 재공급되어 재투입됨에 따라 사용목적에 맞는 입도 분포를 갖는 재생골재를 지속적으로 생산하게 되는 것이다.Therefore, aggregates separated by particle size by screening and then divided by particle size can be distributed through a distributor to have a particle size distribution suitable for the purpose of use, and then mixed through a mixer to produce the aggregates. As it is fed back into the crusher and re-injected, it is continuously producing recycled aggregate having a particle size distribution suitable for the purpose of use.

도 5는 본 발명에 따른 혼합기의 실시 예를 단면도로 보인 것으로, 분배기에서 배출된 골재를 혼합하기 위한 혼합기의 구성을 단면으로 보이고 있다.5 is a cross-sectional view showing an embodiment of the mixer according to the present invention, the configuration of the mixer for mixing the aggregate discharged from the distributor in cross section.

즉, 도 1에서 보인 것과 같이, 본 발명은 사용목적에 따라 골재의 입도 분포를 조절하면서 생산할 수 있는 골재 입도 분포 조절방법 및 장치에 관한 것이다.That is, as shown in Figure 1, the present invention relates to an aggregate particle size distribution control method and apparatus that can be produced while adjusting the particle size distribution of the aggregate according to the purpose of use.

이를 위하여 본 발명인 골재 입도 분포 조절방법은 크게 골재를 파쇄하기 위한 파쇄단계(1)와, 파쇄된 골재를 입도 별로 분류선별하기 위한 골재선별단계(2)와, 분류선별된 골재를 사용목적의 입도 분포에 맞게 혼합용 골재와 재투입용 골재로 배분하는 골재배분단계(3)와, 혼합용 골재가 입도 별로 쌓이지 않도록 혼합하는 골재혼합단계(4)와, 재투입용 골재를 파쇄기(미도시)로 재공급하는 골재재투입단계(5)로 구성된다.To this end, the aggregate particle size distribution control method of the present invention includes a crushing step (1) for largely crushing aggregates, an aggregate sorting step (2) for classifying crushed aggregates by particle size, and a particle size for which the classified aggregates are used. Aggregate distribution step (3) for distributing the mixing aggregate and re-entry aggregate according to the distribution, aggregate mixing step (4) for mixing so that the mixing aggregate does not accumulate by particle size, and shredder aggregate for re-entry (not shown) It is composed of an aggregate input step (5) for resupplying with.

상기 파쇄단계(1)는 도로 및 건설현장 등에서 배출된 건설폐기물을 재생골재에 적합한 입도, 입형을 갖도록 파쇄기를 이용하여 파쇄하는 단계로, 이 파쇄단계(1)를 거친 건설폐기물은 재생골재에 접합한 입도, 입형을 갖게 된다.The shredding step (1) is a step of shredding the construction waste discharged from roads and construction sites using a shredder so as to have a particle size and shape suitable for the recycled aggregate, the construction waste subjected to the shredding step (1) is bonded to the recycled aggregate One bite will have shape.

이러한 파쇄단계(1)를 거친 골재는 골재선별단계(2)를 통하여 입도 별로 분 류선별하게 되며, 본 발명에서는 도 2 내지 도 3에서 보인 것과 같이, 골재선별장치(6)의 상부에 설치된 스크린(10)을 이용하여 파쇄된 골재를 입도 별로 분류선별하는 골재선별단계(2)를 수행하게 된다.Aggregate that has undergone such a crushing step (1) is classified by particle size through the aggregate screening step (2), in the present invention, as shown in Figures 2 to 3, the screen installed on the top of the aggregate screening device (6) Using (10) to perform the aggregate selection step (2) to classify the broken aggregates by particle size.

상기 스크린(10)은 골재를 입도 별로 선별하기 위하여 적어도 하나 이상의 걸름망(11a)(11b)(11c)(11d)을 갖고 다수의 프레임(6a)을 수직 및 수평으로 결합하여 이루어진 골재선별장치(6)의 상부에 경사지게 설치된 것을 보이고 있다.The screen 10 has at least one strainer (11a) (11b) (11c) (11d) for screening the aggregates by particle size and the aggregate selection device (6) made by combining a plurality of frames (6a) vertically and horizontally. It is shown to be installed inclined at the top of the).

즉, 파쇄기를 이용한 파쇄단계(1)에서 파쇄된 골재는 골재투입장치(7)를 통하여 스크린(10)의 걸름망(11a) 상으로 공급되는데, 상기 걸름망(11a)을 통과하지 못한 골재는 출구(12)를 통해 배출되고, 걸름망(11a)을 통과한 골재는 그 다음 걸름망(11b)에 공급되어 재선별과정을 거치게 된다.That is, the aggregate crushed in the crushing step (1) using the crusher is supplied to the strainer 11a of the screen 10 through the aggregate input device 7, the aggregate that does not pass through the strainer (11a) is exit ( Aggregate discharged through 12) and passed through the strainer 11a is then supplied to the strainer 11b to undergo re-selection.

따라서, 스크린(10)의 내부에는 필요에 따라 걸름망(11a)(11b)(11c)(11d)의 수를 선택적으로 설치하여 사용할 수 있으며, 예로 이 걸름망(11a)(11b)(11c)(11d)을 통해 분류선별되는 골재의 입도는 각각 40㎜, 25㎜, 15㎜, 5㎜ 등이 있다.Therefore, the number of strainers 11a, 11b, 11c, 11d can be selectively installed and used inside the screen 10 as needed. For example, the strainers 11a, 11b, 11c, 11d. The particle size of the aggregates sorted through) are 40mm, 25mm, 15mm, 5mm, etc., respectively.

그러나, 이는 하나의 예로 사용목적에 따라 걸름망(11a)(11b)(11c)(11d)을 통해 배출되는 골재의 크기는 변결될 수 있음을 사전에 밝혀둔다.However, it is noted in advance that the size of the aggregate discharged through the strainer 11a, 11b, 11c, 11d may vary depending on the purpose of use as an example.

여기서, 이러한 구성의 스크린(10)은 골재를 입도 별로 선별하는 과정에서 진동력을 이용하여 골재의 용이 선별을 유도하기 위하여 진동수단(20) 및 다수의 완충스프링(21)에 의해 자체 진동 가능한 상태로 골재선별장치(1)에 설치된다.Here, the screen 10 of this configuration is capable of vibrating itself by vibrating means 20 and a plurality of buffer springs 21 in order to induce easy sorting of aggregate using vibration force in the process of screening aggregates by particle size. Furnace is installed in the aggregate selection device (1).

이는, 골재투입장치(2)를 통해 공급된 골재가 경사진 스크린(10)의 걸름망(11a)(11b)(11c)(11d)을 자연스럽게 통과하면서 선별이 이루어지도록 하여도 무방하나, 진동수단(20)을 이용하여 상기 스크린(10)을 진동시킬 경우 골재의 선별에 따른 효율성을 높일 수 있게 되며, 진동과정에서의 충격은 완충스프링(21)을 통해 흡수하여 보호할 수 있기 때문이다.This may allow the aggregate supplied through the aggregate input device 2 to naturally pass through the strain screens 11a, 11b, 11c, and 11d of the inclined screen 10, but may be sorted out. When the screen 10 is vibrated using 20), the efficiency according to the selection of the aggregates can be increased, and the shock in the vibration process can be absorbed and protected through the shock absorbing spring 21.

즉, 상기 구성의 진동수단(20)과 완충스프링(21)이 설치된 스크린(10)이 골재선별장치(6)의 상부에 설치된 상태에서 골재투입장치(7)를 통하여 파쇄된 골재가 공급될 경우 진동수단(20)을 통한 진동 과정에서 걸름망(11a)을 통과하지 못한 40㎜이상의 굵은 골재는 출구(12)를 통하여 배출된다.That is, when the crushed aggregate is supplied through the aggregate input device 7 in a state in which the screen 10 having the vibration means 20 and the shock absorbing spring 21 of the above structure is installed on the aggregate selection device 6. The coarse aggregate of 40 mm or more that does not pass through the strainer 11a in the vibrating process through the vibrating means 20 is discharged through the outlet 12.

그리고, 상기 걸름망(11a)을 통과한 40㎜이하의 골재는 스크린(10)의 내부에 설치된 다른 걸름망(11b)으로 공급되고, 이 걸름망(11b)을 통과하지 못한 25㎜이상의 골재는 스크린(10)의 출구(12)를 통해 배출되며, 걸름망(11b)을 통과한 25㎜이하의 골재는 그 하부의 다른 걸름망(11c)으로 순차적으로 공급되어 재선별과정을 거치게 되는 것이다.The aggregate of 40 mm or less passing through the strainer 11a is supplied to another strainer 11b installed in the screen 10, and the aggregate of 25 mm or more that fails to pass through the strainer 11b is screen 10 Discharging through the outlet 12 of the), the aggregate less than 25mm passed through the strainer 11b is sequentially supplied to the other strainer 11c of the lower portion is subjected to the re-selection process.

골재배분단계(3)는 골재를 사용목적의 입도 분포에 맞게 혼합용 골재와 재투입용 골재로 배분하기 위한 단계로, 본 발명에서는 스크린(10)의 출구(12)에 분배기(30)를 설치하여 골재를 입도 분포에 맞게 조절하여 배출하는 골재배분단계(3)를 수행하게 된다.Aggregate distribution step (3) is a step for distributing the aggregate to the mixing aggregate and re-entry aggregate in accordance with the particle size distribution of the intended use, in the present invention, the distributor 30 is installed in the outlet 12 of the screen 10 By performing the aggregate distribution step (3) to discharge by adjusting the aggregate to the particle size distribution.

상기 분배기(30)는 골재배분단계(3)를 수행하는 하나의 예로 이 외에 부지활용차원에서 스크린(10)의 걸름망(11a)(11b)(11c)(11d)에 의해 각각의 입도 별로 배출된 골재를 이송할 수 있도록 분배용 컨베이어 등을 상기 스크린(10)의 출구(12)에 설치하여 사용하여도 무방하나, 본 발명에서는 도시되어 있는 분배기(30)로 설 명함을 밝혀둔다.The dispenser 30 is discharged for each particle size by the filter net 11a (11b) (11c) (11d) of the screen 10 in addition to one example for performing the aggregate distribution step (3). Dispensing conveyors and the like may be installed at the outlet 12 of the screen 10 so as to transfer the aggregates, but in the present invention, the business card is set up as the distributor 30 shown.

즉, 파쇄기에 의해 파쇄된 골재를 입도 별로 분류선별하기 위한 스크린(10)의 출구(12)에 분배기(30)를 각각 설치하여 상기 스크린(10)의 걸름망(11a)(11b)(11c)(11d)을 통과하지 못하고 배출되는 골재를 혼합용 골재와 재투입용 골재로 배분하게 되는 것이다.That is, the distributors 30 are respectively installed at the outlets 12 of the screen 10 for sorting the aggregate crushed by the crusher by particle size, so as to filter the nets 11a, 11b, 11c of the screen 10 ( Aggregate discharged without passing through 11d) is allocated to mixing aggregate and re-entry aggregate.

여기서, 상기 분배기(30)를 이용하여 골재를 혼합용 골재와 재투입용 골재로 분리 배출하는 것은 재생골재의 생산과정에서 특정 입도의 골재만이 과도하게 생산되거나 부족하게 생산되는 것을 방지하기 위함이다.Here, separating and discharging the aggregate into the mixing aggregate and the re-input aggregate using the distributor 30 is to prevent the excessively produced or insufficiently produced aggregate of a specific particle size during the production of recycled aggregate. .

즉, 이러한 역할을 수행하기 위한 분배기(30)의 실시 예는 도 4에서 보인 것과 같이, 걸름망(11a)(11b)(11c)(11d)을 통과하지 못한 골재가 투입되는 입구(31)가 상부에 형성되고, 하부에는 상기 골재를 혼합용 골재와 재투입용 골재로 분리 배출하기 위한 한 쌍의 배출구(32)(33)가 분할 형성되며, 내부에는 상기 배출구(32)(33)가 만나는 분기점(C)에 회동 가능하게 설치되어 투입된 골재를 유도배출하는 가변칸막이(34)로 구성된 것을 보이고 있다.That is, in the embodiment of the distributor 30 for performing this role, as shown in FIG. 4, the inlet 31 into which the aggregate that has not passed through the strainer 11a, 11b, 11c, 11d is introduced into the upper portion. Is formed in, a pair of outlets 32, 33 for separating and discharging the aggregate into the aggregate for mixing and re-entry aggregate is formed in the lower portion, the branching point where the outlet 32, 33 meets therein (C) is shown to be composed of a variable partition 34 is installed rotatably installed to induce discharge of the injected aggregate.

상기 한 쌍의 배출구(32)(33)는 각각 후술될 재투입용 컨베이어(50)와 혼합기(40)에 연결되어 혼합용 골재 또는 재투입용 골재를 공급하게 되며, 가변칸막이(34)는 그 움직임을 통하여 입구(31)를 크기를 조절하여 배출되는 골재의 분포량을 조절하는 역할을 수행하게 된다.The pair of outlets 32 and 33 are connected to the re-entry conveyor 50 and the mixer 40 to be described later, respectively, to supply the aggregate for mixing or aggregate for re-entry, and the variable partition 34 is By controlling the size of the inlet 31 through the movement it serves to control the amount of aggregate discharged.

따라서, 상기 구성의 분배기(30)가 각각 스크린(10)의 출구(12)에 설치됨에 따라 걸름망(11a)(11b)(11c)(11d)을 통과하지 못한 골재는 혼합용 골재 또는 재투 입용 골재로 분리배출되어 재투입용 컨베이어(50) 또는 혼합기(40)로 공급되는 것이다.Therefore, the aggregate that does not pass through the strainer 11a, 11b, 11c, 11d as the distributor 30 of the configuration is installed at the outlet 12 of the screen 10, respectively, the aggregate for mixing or the reinjection aggregate. Separated and discharged to be fed to the re-feed conveyor 50 or mixer 40.

골재혼합단계(4)는 분배기(30)를 통해 배출된 혼합용 골재가 입도 별로 쌓이지 않도록 포집하여 혼합하는 단계로, 비교적 입도가 큰 굵은 골재는 배출방향에서 바깥쪽으로 떨어지고, 입도가 작은 잔 골재는 안쪽으로 떨어져 서로 섞이지 않고 별도 쌓이게 된다.Aggregate mixing step (4) is a step of collecting and mixing the aggregate aggregate discharged through the distributor 30 so as not to accumulate for each particle size, the coarse aggregate having a relatively large particle size falls outward in the discharge direction, the small aggregate fine aggregate They do not fall inward and mix with each other.

즉, 이를 방지하기 위하여 본 발명에서는 혼합기(40)를 이용하여 골재혼합단계(4)를 수행하게 되며, 이러한 골재혼합단계(4)에 사용되는 혼합기(40)의 실시 예는 도 5에서 보인 것과 같이, 분배기(30)를 통해 이송된 골재가 공급되는 공급부(41)가 상부에 형성되고, 하부에는 혼합된 골재를 배출하는 배출부(42)가 형성되며, 내부 가장자리에는 이송된 골재가 낙하하면서 분리되지 않도록 안내하는 안내판(43)이 구비된 것을 보이고 있다.That is, in order to prevent this, in the present invention, the aggregate mixing step 4 is performed by using the mixer 40, and the embodiment of the mixer 40 used in the aggregate mixing step 4 is that shown in FIG. Similarly, a supply part 41 through which the aggregates transported through the distributor 30 are supplied is formed at the upper portion, a discharge part 42 is formed at the lower portion to discharge the mixed aggregate, and the transferred aggregate falls at the inner edge thereof. It is shown that the guide plate 43 is provided so as not to be separated.

여기서, 이러한 구성의 혼합기(40)에 혼합용 골재를 공급하기 위하여 상기 혼합기(40)와 분배기(30)는 연결관(35)을 통하여 연결되며, 이를 도면으로 보이고 있다.Here, the mixer 40 and the distributor 30 are connected through the connecting pipe 35 to supply the mixing aggregate to the mixer 40 of this configuration, which is shown in the figure.

따라서, 이러한 혼합기(40)가 연결관(35)을 통하여 분배기(30)와 연결됨에 따라 상기 분배기(30)를 통하여 배출된 혼합용 골재는 상기 혼합기(40)의 상부 공급부(41)를 통하여 혼합기(40)의 내부에 공급되는 과정에서 내부 가장자리에 구비된 안내판(43)에 부딪쳐 상호 혼합되는 것이다.Therefore, the mixing aggregate discharged through the dispenser 30 as the mixer 40 is connected to the distributor 30 through the connecting pipe 35 is passed through the upper supply part 41 of the mixer 40. In the process of being supplied to the inside of the 40 to hit the guide plate 43 provided on the inner edge is mixed with each other.

이때, 상기 안내판(43)이 혼합기(40)의 내부에 서로 엇갈리게 구비될 경우 굵은 골재와 잔 골재의 낙하지점이 배출구(42)를 향하도록 하여 혼합작용을 더욱 극대화시키게 된다.At this time, when the guide plate 43 is provided to cross each other in the mixer 40, the falling point of the coarse aggregate and the fine aggregate is directed toward the outlet 42 to further maximize the mixing action.

이와 같은 골재혼합단계(4)를 통하여 입도 분포가 조절된 재생골재는 혼합기(40)의 하부에 자연스럽게 쌓이거나, 본 발명에서 보인 것과 같이, 별도의 수거함(44) 또는 배출용 컨베이어를 이용하여 도로현장이나 건설현장으로 이송되며, 상기 수거함(44)이 아닌 별도의 배출용 컨베이어를 사용할 경우에는 이 컨베이어의 낙하지점에 혼합기(40)를 설치하여 골재분리가 발생하지 않도록 하는 것이 바람직하다.The recycled aggregate whose particle size distribution is adjusted through such aggregate mixing step 4 is naturally piled up in the lower portion of the mixer 40, or as shown in the present invention, using a separate collection box 44 or a discharge conveyor. When transported to a site or a construction site, when using a separate discharge conveyor other than the collection box 44, it is preferable to install a mixer 40 at the dropping point of the conveyor so that aggregate separation does not occur.

골재순환단계(5)는 스크린(10)의 출구를 통하여 배출된 골재 중 분배기(30)를 통하여 배출된 재투입용 골재를 다시 파쇄기로 재공급하는 단계로, 상기 분배기(30)를 통해 배출되는 재투입용 골재는 이송관(36)을 통해 재투입용 컨베이어(50)로 공급된 후 이 컨베이어(50)를 따라 파쇄기로 재투입되어 파쇄되고 선별됨에 따라 사용목적에 맞는 입도 분포를 갖는 골재를 지속적으로 생산하게 되는 것이다.Aggregate circulation step 5 is a step of resupplying the re-input aggregate discharged through the distributor 30 of the aggregate discharged through the outlet of the screen 10 again to the crusher, which is discharged through the distributor 30 Aggregate for re-feeding is supplied to the re-feeding conveyor 50 through the transfer pipe 36, and then re-injected to the crusher along the conveyor 50 to be crushed and sorted to have an aggregate having a particle size distribution suitable for the purpose of use. It will continue to produce.

상기와 같은 본 발명의 구성에 의하면, 파쇄된 골재를 분류선별하기 위한 스크린의 출구에 분배기가 설치되고, 이 분배기를 통해 배출된 혼합용 골재는 혼합기가 포집하여 혼합함으로써, 특정 입도의 골재를 필요에 따라 조절하여 생산할 수 있게 된다.According to the configuration of the present invention as described above, a distributor is installed at the outlet of the screen for sorting the crushed aggregate, and the mixing aggregate discharged through the dispenser is required to aggregate aggregate of a specific particle size by collecting and mixing the mixer. It can be adjusted according to the production.

또한, 입도 분포에 따라 배출되지 않은 재생골재는 재투입용 컨베이어를 통해 자동으로 파쇄기로 재투입됨으로써, 입도 별로 분리된 골재를 일정 비율로 다시 혼합하여 사용목적에 맞는 입도 분포를 갖는 골재를 지속적으로 생산할 수 있게 된다.In addition, the recycled aggregate that is not discharged according to the particle size distribution is automatically re-inserted into the crusher through the re-input conveyor, so that the aggregate having the particle size distribution suitable for the purpose of use is mixed by re-mixing the aggregate separated by particle size at a certain ratio. Will be able to produce.

따라서, 특정 입도의 골재만이 과도하게 남거나 부족하게 되어 이를 별도로 쌓기 위한 공간이 필요 없게 되고, 적정 입도 분포에 따른 시장성 확보를 통해 골재를 단순 매립하거나 노반재용과 같이 저급한 용도보다는 보조기층용과 같은 고가의 용도로 활용할 수 있어 폐기비용의 낭비를 줄임과 동시에 경제적 효과를 누릴 수 있게 되는 것이다.Therefore, only aggregates of a certain particle size are excessively left or lacked so that there is no need for space for stacking them separately. It can be used for the purpose of reducing waste of disposal cost and at the same time can enjoy economic effect.
