1. Product Overview

The LNG Through-Type Polishing Machine is an automatic surface finishing system designed for external polishing of LNG cylinder shells. Integrated seamlessly with a conveying line, the cylinders are automatically loaded into the machine, where horizontal spiral feed ensures continuous polishing. Equipped with constant-pressure polishing heads, motorized screw lift adjustments, and sealed dust-control enclosures, this system delivers high-speed, high-precision surface finishing for a wide range of cylinder diameters.

2. Key Features

• Fully Automated Pass-Through Operation: Cylinders are transported in spiral motion while being polished, ideal for mass production.

• Constant-Pressure Head: Pneumatically adjusted to ensure uniform surface polishing without overgrinding.

• Flexible Diameter Adjustment: Motor-driven lift for polishing head, manual follower wheel adjustment to suit different cylinder diameters.

• Versatile Polishing Media: Compatible with abrasive belts, flap wheels, wool wheels, nylon disks, cloth wheels.

• Enclosed Safety Housing: Full enclosure with transparent window and dust extraction ports to ensure safety and cleanliness.

• Electrical and Mechanical Safety: Top and bottom limit protections prevent overtravel and protect components.
