A steel coil shot blasting machine operates by mechanically propelling abrasive media, such as steel shots or grits, at high velocity towards the surface of steel coils. The impact of the abrasive material removes contaminants, rust, or old coatings, leaving the surface clean and prepared for subsequent processing。 The key component of this machine is the blast wheel, which converts electrical energy into kinetic energy to propel the abrasive media. The blast wheel consists of blades, an impeller, and a control cage. The control cage regulates the flow and direction of the abrasive media, ensuring it hits the steel coils at the correct angle and speed。
