LIJIANG Glass Automatic Vertical Glass Sandblasting Machine sucks the sandblasting medium from the sandblasting material box through compressed air, and then sprays it out through the sandblasting gun. When compressed air flows through the sandblasting gun, the air flow speed is accelerated by the shrinkage and expansion of the nozzle, forming a high-speed airflow. Under the action of air flow, the sandblasting medium is accelerated and ejected, impacting the surface of the workpiece for grinding and removing surface dirt. The sandblasting material box and sandblasting pipeline system of the sandblasting machine need to ensure the smoothness and stability of the sandblasting medium to ensure the sandblasting effect.
