The conveyor belt 15 delivers the screened sand and ash to the interior of the mixing barrel 1. After the sand and ash enter the interior of the mixing barrel 1, the hydraulic press 7 is started. The hydraulic press 7 drives the hydraulic rod 8 to extend so that the hydraulic rod 8 drives the lifting plate 501 to move downward.
