본 발명은 칩 등의 형태로 공급되는 폐타이어와 같은 피분쇄물을 미세한 분말로 분쇄하기 위한 미세분말 생성장치에 관한 것으로서, 더욱 상세하게는 멧돌 형상과 같이 절삭면이 서로 대향하도록 배치된 두 개의 절삭날을 회전시켜 미세분말을 생성시키되 상기 절삭날의 눈금 크기가 미세분말의 배출방향을 따라 순차적으로 감소하도록 구성함으로써 피분쇄물의 분쇄 효율을 최대화할 수 있는 미세분말 생성장치에 관한 것이다.The present invention relates to a fine powder generating device for pulverizing a grinding material such as waste tires supplied in the form of chips, etc. into fine powder, and more specifically, two cutting surfaces are arranged so that the cutting faces face each other, such as a shape of stone. The present invention relates to a fine powder generating apparatus capable of maximizing the grinding efficiency of a pulverized object by rotating the cutting edge to generate fine powder but reducing the scale of the cutting edge in order along the discharge direction of the fine powder.
현대 사회의 급속한 산업화 및 도시화 경향으로 인하여 여러 가지 소재로 이루어진 다양한 공업 제품들이 대량으로 생산되고 있으며, 이러한 추세에 따라 이들 공업 제품들의 폐기 처분으로 인한 각종 산업 폐기물들도 대량으로 발생되고 있다. Due to the rapid industrialization and urbanization trend of the modern society, various industrial products made of various materials are produced in large quantities, and according to this trend, various industrial wastes due to the disposal of these industrial products are also generated in large quantities.
이러한 산업 폐기물들을 야적장에 오랜 시간동안 방치하거나 소각할 경우에는 오염물질의 배출로 인하여 주변 환경을 심각하게 오염시키게 됨은 물론, 이들 폐기물에 포함된 재활용 가능한 자원들이 그대로 버려지게 되는 문제점이 있다.When these industrial wastes are left in the yard for a long time or incinerated, the environmental pollution is seriously polluted by the discharge of pollutants, and the recyclable resources included in these wastes are discarded as they are.
따라서, 최근에는 이들 산업 폐기물에서 배출되는 폐자원들을 적극적으로 재활용하기 위한 연구가 활발하게 진행되고 있으며, 그 중 대표적인 예가 폐전선 피복이나 폐타이어 등에서 얻을 수 있는 합성수지 소재 또는 고무 소재 등의 폐자원들을 분쇄하여 보도블럭 또는 건축자재 등으로 재활용하는 기술이라고 할 수 있다.Therefore, in recent years, researches are being actively conducted to actively recycle waste resources emitted from these industrial wastes, and representative examples thereof include waste materials such as synthetic resin materials or rubber materials obtained from waste wire coating or waste tires. It can be said to be a technology that is crushed and recycled into sidewalk blocks or building materials.
그러나, 종래 기술에 따른 분쇄장치들은 서로 맞물리도록 회전하는 분쇄용 칼날을 사용하는 방식이어서 유효 분쇄면적이 작고 칼날의 회전속도를 증가시키는데도 한계가 있거나, 한국공개특허 제2002-0076661호 등에 개시된 전체적으로 눈금의 크기가 일정한 절삭날을 이용하는 방식이어서 하나의 분쇄공정에서는 칼날의 조도에 따라서 분쇄 결과물의 입경이 동일하기 때문에 원하는 수준의 입경으로 피분쇄물을 분쇄하기 위해서는 칼날의 조도를 변경하면서 순차적으로 분쇄하는 것이 불가피하였다.However, the grinding apparatus according to the prior art is a method using a grinding blade that rotates to mesh with each other, so that the effective grinding area is small and there is a limit to increase the rotational speed of the blade, or as disclosed in Korean Patent Laid-Open No. 2002-0076661 or the like. Since the size of the scale uses a cutting edge with a constant size, in one grinding process, the particle size of the grinding result is the same according to the roughness of the blade, so to grind the workpiece to the desired particle size, change the roughness of the blade in order It was inevitable.
이로 인하여, 종래 기술에 따른 분쇄장치는 상기 폐자원을 원하는 수준의 조밀한 입경으로 분쇄하기 위해서는 복수 단계의 분쇄 공정(예를 들어, 조립 분쇄공정, 중립 분쇄공정 및 미립 분쇄공정 등)을 거쳐야 하기 때문에 장치의 구성이 전체적으로 대형임은 물론, 그에 따라 생산비용도 크게 증가되는 문제점이 있었다. For this reason, the pulverizing apparatus according to the prior art has to go through a plurality of stages of grinding (for example, granulation grinding, neutral grinding and fine grinding) in order to grind the waste resources to a desired level of dense particle size. Because of the large configuration of the device as a whole, there was a problem that the production cost is greatly increased accordingly.
또한, 상기 종래 기술에 따른 분쇄장치들은 복수의 공정을 거쳐야 비로소 원하는 입경의 미세분말을 얻을 수 있기 때문에 다량의 피분쇄물을 처리할 경우 전체적인 공정 시간이 크게 증가되어 장치의 생산효율 및 경제성을 크게 저감시키는 문제점도 있었다.In addition, since the pulverizer according to the prior art can obtain a fine powder having a desired particle size only through a plurality of processes, the overall process time is greatly increased when a large amount of pulverized material is processed, thereby greatly increasing the production efficiency and economic efficiency of the apparatus. There was also a problem of reducing.
