The present invention relates to an aggregate washing apparatus for producing high-quality aggregates by washing and screening aggregate materials such as crushed stone powder or waste concrete powder and masatosa, and more specifically, aggregate raw materials (crushed stone powder, waste concrete powder, It produces high quality aggregate by removing foreign substances (vinyl, waste wood, plastic, fiber, etc.) mixed in Masatosa, and washing and sorting fine powder or fine powder attached to aggregate material through washing process. It relates to an aggregate cleaning device that suppresses the generation of waste water.

In general, aggregates such as sand or gravel, which are used as concrete for construction, are mostly collected from rivers, rivers or the sea, washed with water, and produced by screening them by size, or crushed in recycling crushing sites of quarries or waste concrete. Aggregate is produced and used by work.

However, in recent years, the collection of aggregates in rivers and rivers is a major problem due to the destruction of the natural environment and the depletion of resources, and the production of aggregates in quarries or waste concrete recycling crushing sites includes excessive amounts of stone, foreign matter and fine particles. As a result, the production of sand and fine aggregates was not unreasonable, and the production of aggregates was not sufficient because the production of high-quality aggregates was insufficient.

Most of the crushed stone powder from the construction waste is used for road compaction or cover, and the recycling of waste concrete is limited to a part of the waste concrete. Since the foreign material is not effectively removed, the aggregate material is mixed with a large amount of foreign matter (vinyl, waste wood, plastic, fiber, etc.) and fine powder and fine powder, so that the strength is low and the absorption rate is high, and thus it is not recycled as construction aggregate.

Looking at the process of waste concrete in recent construction wastes, first, crushing (crushing) in the crushing process to a suitable particle size and then using a metal separator to separate and remove the steel and metal mixed in the crushed aggregate In the sorting process, a vibrating screen sorter or a drum sorter is used for sorting to an appropriate particle size as an aggregate. Here, some foreign matters having light specific gravity are separated through a separation process using a blower and then washed to produce the aggregate.

Most of the existing aggregate washing process is applied to the sorting and washing device of the water tank method, the aggregate is produced by sorting some floating foreign matter and aggregate in the sorting and washing apparatus and washing fine powder and fine powder attached to the aggregate.

The sorting and washing apparatus according to the conventional water tank method is usually discharged by collecting or lifting floating foreign matter by generating water or vortex while the recycled aggregate is discharged to the outside by the discharge conveyor after the washing process in the tank. As in the prior art, the washing method using water or vortex has a problem that the foreign substances mixed in the waste concrete cannot be effectively separated from the aggregates, so that the washing and sorting operations cannot be efficiently performed. Also, a lot of water must be used during the washing of the aggregates. Because of this, a large amount of wastewater is generated and there is a problem of contaminating groundwater and water resources.

The present invention has been made to solve the problems of the existing aggregate cleaning device as described above, remove the floating foreign matter mixed in the aggregate material (crushed stone powder, waste concrete stone powder, Masatosa), fine attached to the aggregate raw material It is a main object of the present invention to provide an aggregate washing apparatus that prevents contamination of groundwater and water resources by producing high quality aggregates by washing and sorting powder or fine powder through a washing process to minimize the generation of waste water. .
