The present invention maintain the efficiency of the easily by the production process of a mesh net constructed prevents the phenomenon of aggregate being screened is lost to the outside, as well as easily block the fugitive dust occurring during the screening process and the reject box is available and the internal selector is to, in a vibration sorter that is inside the mesh network is provided and enables screening by the desired size of the aggregate by vibration by driving the motor unit is configured to enable the height a, fixed to the upper portion of the body and the supply of the aggregate line which is connected with an inlet connected to a collecting line allows for fugitive dust generated during screening and home Jingu cover member is formed; Pressing the upper surface of the lid member positioned to enable fixing to an upper portion of the main body or separate fixing member which is formed to maintain a fixed state by a strong magnetic force; provides a vibration screening machine comprising a cover.
