In terms of eco-friendliness and recycling of resources, construction wastes generated when dismantling construction and building structures are collected by construction waste intermediate treatment companies and are produced as quality resources through intermediate treatment processes. In particular, the recycled aggregate obtained by intermediary treatment of waste concrete, which accounts for about 60 to 70% of construction waste, has been greatly increased in utilization based on the Act on Promotion of Recycling.

Looking at the intermediate treatment process of the construction waste, the collected construction waste is shredded below a certain particle size by various shredders, during which the rebars are sorted and recycled by magnetic separators, such as wood chips or styrofoam. Organic foreign matter is removed to less than 1% by methods such as a blower and a water tank to produce recycled aggregates.

However, even the recycled aggregate obtained through such a process, due to segregation caused by the characteristics of cement mortar and compression crusher attached to the aggregate surface, the physical properties of the aggregate is not good compared to natural aggregate, especially the density is 2.1 ~ 2.3g / It is known to be as low as cm 3 and have a water absorption rate of 4% or more, which is very high compared to natural aggregate. As a result, when the recycled aggregate produced by the conventional method is used for concrete, the adhesion between cement paste and aggregate decreases, and the compressive strength decreases and the durability decreases, making it impossible to use the recycled aggregate for concrete. In reality, it is urgent to develop a device that can solve this problem.

In order to solve the above problems, in the present invention, as a device for peeling off the mortar attached to the circulating aggregate and removing segregation, the impact mortar and the frictional force generated by the vibration of the mortar and the mortar-type conveyor itself generate the attached mortar. It is an object of the present invention to provide a mortar peeling and segregation removal device with a ball-type circulating aggregate, which can improve the quality of circulating coarse aggregate by crushing the poor portion at the same time as peeling.
