Liquid mobile sandblasting machine is a surface treatment equipment that combines liquid sandblasting technology and mobile design. It is mainly used for surface treatment of metal and non-metal materials. Its working principle is to transport the abrasive liquid (a mixture of abrasive and water) to the spray gun through the abrasive liquid pump, and then accelerate the abrasive liquid through compressed air to spray it onto the surface of the workpiece to achieve the effect of cleaning, rust removal, deburring and beautification.
