In the crushing apparatus of the waste concrete aggregate according to the present invention configured as described above, first, the waste concrete is crushed several times, and the crushed aggregate of 40 mm or less (including the fine aggregate of 6 mm or less) is introduced into the aggregate input hopper 4. After that, when the vibration motor 22c1 of the vibration unit 2 is driven, the vibration rotating shaft 22c is rotated at a speed of about 2000 to 2200 rpm. When the vibration rotating shaft 22c is rotated, the vibration rotating shaft 22c is rotated. Vibration is generated by the vibrator 22c2. In other words, the vibration grinding plate 23 of the vibration unit 2 inclined obliquely to the support 11 of the support frame 1 is in a state of vibrating in the vertical direction, that is, the normal direction of the inclination.

At the same time, when the eccentric motor 35 of the eccentric rotation part 3 is also driven, the eccentric rotation shaft 34 is rotated by the eccentric motor 35, and when the eccentric rotation shaft 34 is rotated in this manner, the eccentric cam 34a is rotated. As a result of being supported by the bearing housing at the end of the original tube 33, the rotary side plate 32 and the rotary grinding plate 31 are allowed to flow counterclockwise.

More specifically, the rotary grinding plate 31 is gradually lifted upward while being in close contact with the vibration grinding plate 23 to the maximum while being pulled downward to rotate a series of trajectories that are opened.

In this way, the waste concrete aggregate introduced from the aggregate input hopper 4 in the state where the vibrator 2 and the eccentric rotation part 3 are operated is ascended to the top dead center by the eccentric cam 34a of the eccentric rotation shaft 34. Since the rotary grinding plate 31 and the vibration grinding plate 23 is pressed, the aggregates having cracks are crushed, and the other crushed aggregates are pressed against each other and polished. Thereafter, while the rotary grinding plate 31 is lowered, the aggregates are continuously lowered while the aggregate is pulled downward, so that the continuous crushing and polishing are performed.

At this time, the rotation side plate 32 of the eccentric rotation part 3 is to be smoothly rotated while being elastically supported by the spring 37 of the buffer spring (32b) and the support rod (36).

As such, the aggregate input hopper 4 or the vibration grinding plate 23 and the rotary grinding plate are crushed and polished by the vibration grinding plate 23 of the vibration unit 2 and the rotary grinding plate 31 of the eccentric rotation unit 3. When water is sprayed between the 31, it is possible to remove the dust generated when the crushed aggregates collide with each other, as well as to clean the cement paste or the dirt on the surface of the aggregate.

Then, the rotary grinding plate 31 is in close contact with the vibration grinding plate 23 by the rotational movement of the eccentric rotation part 3 to perform an operation such as rubbing the waste concrete aggregate therebetween. As well as fracture of the aggregate, the angular portions of the aggregate are polished and blunted.

In addition, the waste concrete aggregates thus broken and polished are passed through them and transferred to a next stage through a separate screw conveyor (not shown).

On the other hand, when abnormality occurs during the crushing and polishing operation of the waste concrete aggregate or when the vibration grinding plate 23 of the vibrator 2 and the eccentric rotating plate 31 of the eccentric rotation part 3 are replaced or when the waste concrete aggregate In order to adjust the distance from the rotary grinding plate 31 by size, as shown in FIG. 7, the fastener 15 of the holder 16 is separated and the piston rod of the cylinder 13 is extended to vibrate the side plate. Opening the upper end of the 21 to adjust the number of the inclination adjusting member 17 disposed between the fastening bracket 14 and the upper surface of the fixing stand 16 to continuously crush and polish the waste concrete aggregate You can do it.

In addition, the number of sets of the vibrator 2 and the eccentric rotor 3 of the present invention may be freely adjusted according to the degree of crushing and polishing of the waste concrete aggregate.

As described above, the crushing device of the waste concrete aggregate of the present invention gives a vibration and pressurized while rubbing the waste concrete aggregate crushed to a predetermined particle size rubbed the waste concrete aggregate with cracks and other waste concrete aggregates In the pressed state, the edges are blunted as they are rotated and rotated, so that the grain shape is polished into a rounded spherical shape. This makes it easy and easy to polish the surface edges of the waste concrete aggregate. Get the effect.
