Airless Gas Cylinder Shot Blasting Machine
The Airless Gas Cylinder Shot Blasting Machine manufactured by Finishree Equipment’s Pvt. Ltd. is an advanced, high-productivity surface treatment solution developed specifically for external cleaning, descaling, old paint stripping, and surface profiling of LPG cylinders, CNG cylinders, high-pressure industrial gas bottles (oxygen, nitrogen, hydrogen, argon), and fire extinguisher shells.
Equipped with high-efficiency airless blast wheels (turbines) firing high-grade cast steel shots and grit, the machine achieves comprehensive 360-degree surface coverage across the cylindrical body, top collar/dome, neck shoulder, and bottom foot ring without any manual repositioning. It delivers consistent surface cleanliness to SA 2.5 and SA 3.0 (ISO 8501-1) standards, creating an ideal anchor profile for electrostatic powder coating, zinc thermal spraying, or industrial liquid painting.
Working Principle & Conveying Mechanisms
Finishree manufactures two versatile automated conveying configurations tailored to production volumes and plant layouts:
1. Continuous Skew Roller / Diabolo Roller Conveyor Type:
Cylinders are fed onto motorized conical diabolo rollers that impart continuous
linear forward travel combined with axial rotation. As the rotating cylinders
pass through the blast chamber, strategically angled blast turbines target the
cylinder body, neck, and bottom rim, ensuring high-speed continuous output (up
to 120–180 cylinders/hour).
2. Overhead Continuous / Indexing Spinner Hanger Type:
Cylinders are suspended on dedicated hooks from a monorail or overhead conveyor
loop. Inside the blast enclosure, each hanger rotates independently at
controlled RPMs directly in front of the high-velocity blast streams, ensuring
thorough cleaning of complex neck collars, valve shrouds, and bottom foot rings.
3. Direct Blast Wheel Geometry & Armor Enclosure:
Heavy-duty bi-directional blast wheels with high-chrome alloy blades throw steel
shots/grit at 75–80 m/s. The blast cabinet is fortified with replaceable 11–14%
Manganese (Mn13) cast alloy plates. Entry and exit vestibules are fitted with
multiple layers of durable rubber curtains to eliminate shot leakage.
4. Automatic Media Recovery & Air-Wash Separation:
Spent abrasive, dislodged rust, and pulverized old paint fall through the floor
hopper into a longitudinal screw conveyor, followed by a vertical bucket
elevator and a high-efficiency rotary screen with an Air-Wash Separator. Dust
and fine broken media are segregated into the collector, while good steel shots
are recycled into the blast storage hopper.
5. Eco-Friendly Pulse-Jet Dust Extraction:
A continuous reverse pulse-jet dust collector maintains negative air pressure
across the blast cabinet, keeping dust emission levels below 10 mg/Nm³ in
compliance with environmental and pollution control norms.
Key Machine Features
