Description

Technical Field [0001] The present invention relates to a crusher for crushing asbestos,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crusher for crushing waste asbestos generated in a road repair work, etc., and more particularly, to a crusher for crushing waste asbestos by rotation of blades coupled to two axes of a fixed shaft and a variable shaft.

Generally, waste asbestos recycling apparatus for recycling waste asphalt waste, which is an asphalt waste, finely crushes waste asbestos, which is a large lump type asphalt waste collected in the beginning, and mixes the crushed waste asphalt with an appropriate amount of aggregate and asphalt oil in a heated state It is an assembly type device that regenerates as new asphalt through a series of processes.

Since the conventional waste asbestos regenerating apparatus does not include a separate device for crushing waste asbestos, most of the waste asbestos in the form of lumps collected in the first place is crushed in a separate place and then transported to a place where the waste asphalt recycling apparatus is installed .

Especially, the crusher which is mainly used for waste asbestos is jaw crusher, hammer crusher, and impact crusher. First, JOo crusher is crushed between fixed JO and moving JO. And when it is broken, the movable jaw moves forward toward the fixed jaw while being retracted, and the waste asbestos contained in the shredding space is crushed by applying impact and pressure. In addition, the hammer crusher is configured to crush the waste asbestos accommodated in the receiving space therein by the impact force of the hammer. The impact crusher is a method of crushing the waste ascon by impacting the special plate by high-speed rotation of the impact blade.

However, since the JO crusher is inexpensive and has a simple structure, the crushed size is not constant. Therefore, it is difficult to use it in the summer season because the crusher is not crushed by the moving crusher but is deformed into a crushed shape. The hammer crusher and the impact crusher have a problem in that the crushed material is not uniform in size and the crushed material is too much generated during the crushing process.

In addition, the above-mentioned JOo crusher, hammer crusher, and impact crusher have a difference in degree but they commonly adopt a method of crushing waste asbestos by an impact force, so that a collision noise is generated. Therefore, it is the government regulation that the shredding work in the city center is regulated.

Therefore, since the crushing operation can be performed only in the outskirts outside the city center, it is difficult to supply crushed waste ascon in real time, and the crushed waste ascon is required to be transported to the place where the recycling device is located. .

In addition, the crusher is relatively large, which makes it difficult to mount or transport or handle the crusher. Also, since the crusher generates a large amount of dust during the crushing operation, the crusher not only causes pollution of the surrounding environment, but also becomes an environmental factor harmful to workers. In addition, the crusher causes segregation of the aggregate contained in the waste asphalt when the waste asphalt is crushed, resulting in unevenness in particle size, specific gravity, and composition of the powder particles, resulting in non-uniformity of recycled ascones of high quality .
