Ronning Interior Cleaning with lift

M177-000-002

A number of steel rods are placed in each cylinder. The machine turns them upside down while slowly rotating them.

Compared to blaster this is much cheaper and the entire cylinder will be cleaned (even bottom and shoulder). This method is gentle and there's no risk for damages on the internal surface. It works automatically and doesn't require personal supervision.

The machine is supplied with a protective grating covering 4 sides. Lift arrangement to enable safe removing of steel rods without removing the cylinders from the machine. One man can clean 8 cylinders per hour.

Operation:

  • The machine will run the preset time- Atomatic stop.
  • Atomatic tilt to emptying position
  • Access to rear to remove the steel rods
  • Steel rods are collected in two portable containers.
  • Press push button for automatic return to loading position

The cylinders are placed in the machine, which turns them upside down 22 times a minute while slowly rotating them. The cylinders are rotated to approx. 30° at the end position by this device. The rods move along the cylinder walls, when the peened ends of the rods scraping off the rust. At the end positions the rods strike the shoulder and bottom with considerable force, thereby loosening the rust. The sawdust, which always follows with the rods, absorbs the rust powder, and after a quarter of an hour even the most rusty cylinders are completely clean. The sawdust is removed by an ejector which operates with compressed air from a compressor or gas cylinder.The machine is of simple but robust construction.
