QL6910 vertical multi-functional continuous shot blasting machine This machine is a vertical multi-functional steel to the processing equipment, mainly used to remove H welded steel, steel plates, profiles, and rolling the metal oxide component, rust and foreign matter, so that access to clean metal surfaces. This model can optimize the use of welded H steel fabrication and steel surface condition, and increase corrosion resistance, improve and improve product quality and appearance within, greatly reducing the clean-up operations of the labor intensity and environmental pollution. This machine is grid steel, rolling stock, ship bridges, engineering machinery, metallurgical and chemical containers, boilers and other manufacturing best optimization models.
