<p>PURPOSE:To eliminate combustion oxidation consumption and to completely eliminate air pollution by cutting an aluminum layer in small pieces, impacting a shot ball to the surface thereof at high speed and removing a coating physically by the kinetic energy thereof. CONSTITUTION:A coated aluminum or aluminum alloy chip is cut in small pieces. Shot balls are collided by projecting at high speed by the impeller of a shot part 2 with the surface coating of the aluminum made in small pieces inside a pot type drum 1 or aluminum alloy chip and the coating is removed by peeling from the aluminum or aluminum alloy chip by the impact force and friction force thereof.</p> |
