Description

Recycling aggregate sorting apparatus The present invention relates to a recycled aggregate sorting device capable of removing foreign substances from recycled aggregate obtained after the demolition of a building structure and sorting recycled aggregate of a certain size. Recycled aggregate refers to the use of waste concrete generated during the demolition of concrete structures as aggregate after undergoing physical or chemical treatment processes, and the quality standards for recycled aggregate are set forth in Article 35 of the Act on the Promotion of Recycling of Construction Waste. These construction wastes are usually produced by being separated into soil and aggregates through processes such as crushing, grinding, and the discharge of foreign substances. Vibratory screening devices are commonly used to sort aggregates by size and separate foreign substances mixed in the aggregates to secure only pure aggregates. A vibrating screen device feeds aggregate into a screen mesh having a sieve shape and applies vibration to separate the aggregate from foreign substances, thereby sorting the aggregate or sorting the aggregate by size. However, in conventional vibratory screening devices, since the screen mesh is installed at an angle, aggregates fed into the screen mesh roll down along the upper surface of the screen mesh and are screened. Since the vibration of the vibratory screening device is generated with the same amplitude and force from the top to the bottom of the screen mesh, the rolling speed of the aggregate is relatively constant in the section where the aggregate is first fed, but as it moves toward the bottom, the rolling speed of the aggregate gradually increases due to acceleration, so screening by the screen mesh is not fully achieved, and a large amount of aggregate is discharged outside the screen mesh, which causes a problem in that the efficiency of aggregate screening drops sharply. In addition, conventional aggregate sorting devices have a problem in that aggregates or foreign substances frequently get caught in the holes of the screen mesh, causing the holes to gradually become clogged, which significantly reduces the sorting efficiency of aggregates.
