The present invention relates to a drying apparatus for producing aggregate by drying moisture-containing masato or waste stone powder and earth and sand, and more specifically, to dry aggregate materials such as moisture-containing masato, waste stone powder and earth and sand. The present invention relates to a drying apparatus for manufacturing aggregate, which makes it easy to sort the aggregate by separating the aggregate (sand, gravel), fine powder and foreign matter.

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 has become a big problem due to the destruction of the natural environment and the depletion of resources. Also, the production of aggregates in quarries or waste concrete recycling crushing sites is caused by the excessive inclusion of stone powder and fine particles. The production of aggregates and fine aggregates is not only unreasonable, and it is not possible to produce high quality aggregates.

On the other hand, the aggregate produced by recycling waste concrete is not only distributed evenly by the standard, but also contains large amounts of garbage and other foreign substances such as earth and sand fines, vinyl chips, wood chips, and tree roots. The quality of the aggregates could not be guaranteed due to the poor strength and high water absorption.

Therefore, in recent years, various techniques for producing aggregates for producing aggregates from masato, waste stone powder, and earth and sand have been proposed in order to increase the quality and production of aggregates. Since it contains a large amount, there was a problem that the sorting process for screening the aggregates by specification is not made efficiently.

In other words, since most of the aggregate materials such as masato, waste-rock powder and earth and sand are contained in rainwater or sediment water that penetrates underground, such moisture causes aggregates, fine powder and foreign matters to aggregate together in the aggregate raw material, and also the screening process. In addition to the segregation of the segregator in the screening because the screening operation is not made efficiently, there was a problem that the aggregates and fines and foreign matters were not selected separately.

In the above, the moisture contained in the aggregate material such as masato, waste stone powder and earth and sand aggregates the aggregate, fine powder and foreign matter together so that the aggregate content is first removed to some extent before the production process, In the past, the moisture contained in the aggregate raw material was dependent on the natural drying in the field, which took a long time and was inefficient.

The present invention has been devised to solve the problems of the existing aggregate production as described above, and dried by giving a hot air while digging and scattering in the state of transporting aggregate raw materials such as masato, waste stone powder, earth and sand containing water to one side. It is an object of the present invention to provide a drying apparatus for producing aggregate, which separates fine powder and foreign matter so that sorting of aggregate is easily performed.
