The present invention relates to a mortar peeling device for circulating fine aggregates by grinding and vortex control, and in particular, by installing a vortex control unit for converting the rising vortex generated between the inside of the tank and the lower end of the inlet into a descending vortex, and separating plate and discharge pipe. The grinding part is installed in between, so that foreign matters contained in the pulverized product, such as water, are easily separated through the inlet, and at the same time, the surface of the circulating fine aggregate from which the foreign matters are separated is removed to remove pure mortar. The fine aggregate is obtained to have sufficient compressive strength after constructing the structure.

In general, the construction waste treatment apparatus crushes the particles selected through the primitive sorter using a crusher, and then sorts the metals such as rebars or nails contained therein with a metal sorter, and then selects the particles selected through the particle sorter. Blow air with a blower to remove the debris and then regrind smaller with a crusher.

Next, the remaining metal contained in the regrind particle is separated by the metal sorter, and only the particles having a certain size are sorted through the particle sorter, and then the sharp edges of the sorted particles are removed through the shape improvement process, and the shape is improved. Only a certain size is re-selected from the particles to remove the suspended matter contained in the wet separator, and dehydrated to obtain renewable sand (circulating fine aggregate).

In general, such a wet separator is installed such that a screen conveyor for filtering suspended solids from the upper part of the tank so as to extend transversely from the lower part of the rear side of the tank to the upper part of the tank, and the bucket conveyor is installed to have an upward inclination angle. Due to the specific gravity of the water contained in the tank, the weight of the building waste supplied to the tank is transferred to the bucket conveyor while sinking to the bottom of the tank, and at the same time, the paper powder, wood powder, styrople powder, and waste vinyl powder are relatively light in weight. It is configured to be separated and separated by the screen conveyor by a screen conveyor, but is suitable for obtaining a relatively large particle recycled aggregate, but not suitable for obtaining fine particles of circulating fine aggregate, suspended matter contained in the pulverized particles Also removes only large suspended solids. Remove the organic material together was difficult.

As a way to solve this problem, the present application proposes a foreign material separator of Patent Registration No. 421812 (2004.2.25), and the foreign material is removed due to the difference in the specific gravity in the process of mixing sand containing fine foreign matter with water. Separated and floated to the surface, and foreign matter floated to the surface was removed with the overflow overflow with water, but the foreign matter is separated in the process of moving the sand containing the foreign matter injected with water through the inlet to the bottom In the process of floating foreign matters to the upper part, there was a cause of re-introduction into the inside of the input guide, and the gap between the lower end of the inner body and the separation plate was wide, resulting in an increase in the flow of fluid, resulting in a lower foreign matter removal rate. .

In addition, the sand containing the foreign matter introduced through the inlet is circulated as only the foreign matter contained in the sand is separated from the sand due to a simple difference in gravity in the process of moving to the bottom, and thus the mortar adhered to the sand surface cannot be removed. In the process of blending fine aggregates with cement, the required amount of water was increased and the mixing ratio thereof was changed, which did not have sufficient compressive strength. That is, compared to natural fine aggregate, there is a large amount of mortar that could not be removed from its surface, and more water is absorbed by such mortar, and accordingly cement is not directly contacted with the surface. Will occur.
