The structure of the belt and linkage wheel is prior art and will not be elaborated here. The first magnetic drive roller is driven to rotate by the first motor 336.

The feeding assembly 6 is located on both sides of the recycling conveyor belt 56. Therefore, the recycling drive cylinder 57 drives the recycling conveyor belt 56 to move back and forth between the two feeding assemblies 6. At the same time, the recycling drive mechanism drives the conveyor belt to rotate forward or reverse so as to evenly distribute the abrasive on the two different feeding assemblies 6.

The abrasive located in the hopper groove 621 is transported out from the feeding port 622 and poured into the eddy current grinding assembly 2, realizing the recycling of the abrasive.
