Description

Aggregate screening screen modular with improved screening hole structure The embodiments relate to an aggregate sorting screen modular with an improved sorting hole structure, and more specifically, to an aggregate sorting screen modular with an improved sorting hole structure implemented so that, during the process of sorting aggregates by vibration, the sorting holes expand smoothly and the aggregates fall smoothly through the sorting holes to be sorted. Generally, a large amount of rubble is generated during the process of blasting stone quarries for road or tunnel construction, or for extracting stones from quarries. This rubble is often used to form the subbase layer of road surfaces. For example, rubble is widely used in the construction and building sectors, such as for asphalt paving and building foundations. Since there is a significant amount of rubble left over even when used for forming the subbase layer of road surfaces or building foundations, recently, rubble is crushed by a crusher, and the crushed rubble is separated into aggregates of different particle sizes by a separate aggregate sorting device for recycling. In aggregate sorting devices, a sorting screen through which aggregates pass is required to sort aggregates by size. An aggregate sorting screen equipped in an aggregate sorting device is installed at an angle to the aggregate input end, and aggregates are fed and passed over the sorting screen while simultaneously applying vibration to the sorting screen to sort the aggregates. That is, by operating the sorting screen to vibrate and allowing aggregates to be fed and passed over the sorting screen, aggregates of a predetermined particle size pass through a number of sorting holes formed in the sorting screen and fall, thereby enabling the sorting of aggregates. Meanwhile, a screening screen for separating aggregates is installed at an angle at the aggregate input point. By applying vibration to the screen arranged at an angle, the aggregates are supplied from the input end to the screening screen, flowing down along the angled screen and passing through multiple screening holes formed in the screen. This method of separating aggregates is widely adopted. At this time, a means is needed to ensure that aggregate sorting is carried out more smoothly by ensuring that aggregates do not get stuck in the sorting holes of the screen modular during aggregate sorting. In the past, when sorting aggregates by moving up and down adjacent hole forming pieces to multiple sorting holes, interference occurred such as one hole forming piece climbing on top of another hole forming piece, which prevented the aggregates from falling properly into the sorting holes and thus resulted in the aggregates not being sorted properly.
