The present invention provides a retinispora chip processing device having high workability and merchantability. A retinispora chip surface having a cubic shape used as a filler of a pillow is polished or an edge thereof is processed to be circular, and adhesion of retinispora powder on a chip is prevented. To this end, the retinispora chip processing device according to the present invention comprises: a table; a drum fixed and formed on the table, and filling a retinispora chip; a tray separated at a particular height from the table, constituting a lower side of the drum, and receiving electric power transferred from the outside to be rotated; a suctioning hole communicating with a lower space of a tray to suction the retinispora powder in the drum, and connected with a dust collector; and a guide plate formed on an inner wall of the drum to downwardly moving the retinispora chip ascending when the tray is rotated. Moreover, the tray has sandpaper adhered on an upper surface of the tray to polish the retinispora chip. The tray has hitting projections formed at regular intervals, so the retinispora powder adhered on the retinispora chip on an upper surface thereof is swept away and an edge part thereof can be processed to be circular.
