Our shot blasting machine is especially made for gas cylinder. Using the high speed shot to hit the surface of the cylinder, so that to clean the oxide-scale and make the cylinder surface silver gray and remove the inner stress of the cylinder, improve the surface adhesive force. Meanwhile, we will increase the compressive pre-stress through shot blasting to improve rigidity.
Efficiency: 250pcs/hour
Workpiece weight: <50kg
Workpiece size: 12.5kg/15kg
No of shot blasting machine: 4 sets
Machine total power: about 83.5KW
