Electric derusting machine is high-speed operation by mechanical devices to a certain size of steel by centrifugal force throws out of the shot and the members suddenly impact so as to make the steel casting method for removing surface corrosion, and the electric derusting machine its use is very convenient, and the operation is very the simple, efficiency is very high. The wire cutting ball on its electric rust remover is made of scrap wire rope. Its surface has sharp corners, its rust removal effect is relatively high, and it is also not easy to crush, it can effectively extend its service life. At the same time, the equipment can also effectively remove the rust, scratch, old paint oxidation layer and so on, which can not be removed by the general rust remover.
