When the crushed stones or the small stones that cannot be crushed by the stone crushing roller 6 are on the rotating stone crushing impact column 602, the alloy impact head 603 is driven to rotate rapidly. Under the action of the gold impact head 603, it is pushed backward and enters the arc-shaped part of the leaking stone concentration net 801. The alloy impact head 603 passes through the gap of the leaking stone concentration net 801, pushes the stone backward and upward, and moves the stone upward.
