It is characterized by the configuration.

As another example, a sand sorting plant of Patent No. 415778 has been devised. This aims to obtain high quality aggregates by removing the floating matter and fine powder mixed with aggregates to prevent the degradation of strength when recycling aggregates. The construction waste materials are input and crushed into sand below a certain standard by a crusher. In the plant, a raw material input section in which a hopper and a feeder are installed so that recycled aggregates crushed to a predetermined particle size or less are dispersed, and an impact crusher is installed so that the raw material supplied from the raw material input section is broken into aggregate close to a spherical cube.

The sorting apparatus for sorting and reusing aggregates by using such waste concrete or construction wastes is not only economical in terms of recycling using waste materials, but also when resources are not sufficient as in Korea. In addition, it is very effective in recycling waste resources, and since the waste building is not discarded, it is very environmentally friendly in terms of natural environment.

However, these conventional construction waste recycling apparatus, there are a number of problems in the process of screening the aggregate to recycle the waste concrete or construction waste.

First, the sand is washed with water in the screening process to remove the foreign matters on the sorted sand, and the washed sand is dried for a long time to dry. There is a problem that is difficult to do.

Second, the structure of the transfer screen mounted on the sorting device for sorting the crushed aggregate is composed of one eccentric shaft and move up and down or left and right equally so that the aggregates sorted in the sorting device always progress downward. As the sorting operation is performed only by, the internal aggregates accumulated in the aggregate pile conveyed by the transfer screen are not properly sorted, and thus there is a problem that the sorting operation must be repeatedly performed.

Third, as the sorting operation is repeatedly performed as described above, there is a problem that the sorting operation time is delayed and the enormous loss in productivity improvement is caused, as well as additional costs.

The present invention was devised to solve the problems of the sorting devices that crush waste concrete buildings and recycle them into aggregates. The aggregates are vertically eccentric with each other in the same axis on the lower side of the vibration screen that is transported to the exit side when the aggregates are injected and sorted. By constructing two eccentric cams, the aggregates are floated into the air by the strike of the eccentric cams and then settled down, so that even aggregates contained in the aggregate piles can be sorted so that productivity can be improved by not repeating the sorting operation. In addition to recycling, the selected aggregate can be washed by the sprayed water and dried immediately by the wind blowing through the blower, so that no residue remains in the aggregate to obtain high quality sand. The purpose is to provide a sand sorting device.
