CLOSED LOOP BLASTING EQUIPMENT

摘要

PURPOSE: A closed circuit blasting machine is provided to generally improve workability by deleting a separate grit collection work and reducing work time by the convenient and rapid collection of grit. CONSTITUTION: A closed circuit blasting machine comprises a housing(10), a sanding gun(20), a suction part(30), and a centrifuge(40). A housing covers a work surface to be shut tightly. A sanding gun is connected to the inside of a housing and jets grit with high pressure toward the work surface. A suction part is connected with one side of a housing and inhales grit jetted on the work surface. A centrifuge classifies grit inhaled in a suction part and supplies to a sanding gun again. A wheel for movement(11) is arranged in a housing. Wheels are arranged in the lower part of four corners of a housing respectively. A wheel is a magnet wheel attached on a corresponding work surface. A centrifuge is installed in a sloped state from the upper corner of a housing, and the lower part of the centrifuge faces a lower direction which is a gravity direction when a housing converts a direction to the side.
