Description

[0001] The present invention relates to a cyclic aggregate multi-stage vibration peeling off device,

The present invention relates to a cyclic aggregate multi-step vibration separating apparatus, and more particularly, to a circulating aggregate multi-stage vibration separating apparatus capable of separating foreign matter (paste) adhering to the surface of a circulating aggregate by crushing and crushing the circulating aggregate, ≪ / RTI >

Generally, when the concrete structure or various buildings are lifted, the concrete is disintegrated, and various wastes such as wood, which are generated from various kinds of waste gas and wooden door frames, installed on the building, are discharged.

In order to save energy resources and cost reduction while avoiding environmental pollution caused by these wastes, recycled aggregate is obtained by carrying out regeneration processing to separate and sort into various raw materials so as to be regenerated.

The conventional recycled aggregate apparatus breaks up concrete waste materials step by step in several steps and crushes them to a predetermined particle size, separates and removes reinforcing bars, wood, synthetic resins, soil and the like in this process, , That is, waste concrete crushed aggregate that has been crushed to a predetermined particle size or smaller has been separated and then subjected to reprocessing to obtain high quality aggregates.

In the existing recycled aggregate processing equipment, the cracks generated in the crushing process of waste concrete and the corners of crushed aggregate are angled, so crack cracked aggregate must be split and the edge of crushed aggregate must be polished. This is because the crushed aggregates collide with each other simply by cracking the crushed aggregate and polishing the corners of the crushed aggregate.

A recycled aggregate treatment apparatus related to this technique is disclosed in Korean Patent Registration No. 10-0413325.

When the cylindrical body is rotated, the middle aggregate, which is pulverized concrete in the interior of the main body, moves on the inner wall of the main body due to its own weight. In this process, mutual collision occurs between adjacent intermediate aggregates or between the intermediate aggregate and the inner wall of the main body. The rolling contact phenomenon occurs, and the crushing and breaking action is effected, and the crushing between the particles is effected on the crushing action, so that the weak particles are broken, and the fine particles having the angles are changed into the spherical shape without angles Feature.

However, in the above-mentioned registered patent, it is possible to obtain the intermediate aggregate having a spherical shape of high quality by colliding with the middle aggregate, that is, with the middle aggregate. However, since the middle edge of the middle aggregate is crushed by the self weight of the middle aggregate, Spherical particles can not be obtained properly and it takes much time even if spherical particles can be obtained.
