Centrifugal Wheel Blast

Wheel Blasting Equipment

Wheel Blasting Equipment

FEATURES

Centrifugal wheel blasting is an airless blasting process that utilizes a wheel mechanism and centrifugal force to propel abrasive particles against a batch of work pieces.
The blast wheel’s rapid spinning motion results in a highly efficient blasting process offering shorter time cycles.

Centrifugal blasting does not require a compressed air source required in an air blast type system.

Indsutries & Applications

Industries Served:

  • 3D Printed Parts
  • Automotive – OEM
  • Automotive – Reman
  • Die Casting
  • Defense
  • Construction
  • Fossil Fuel
  • Foundry
  • Mining
  • Plastics
  • Surface Prep
  • Shot Peening
  • Transportation

Advantages

Advantages:

  • Can run large batches of smaller parts all together.
  • No manual flipping or rotating.
  • Blasting on all sides if parts tumble properly.
  • Applications:
    • Batches of parts that can tumble on top of each other without causing damage to the parts.

Centrifugal wheel machines come in a variety of different configurations:

  • Tumble Blast Machines (Batch of parts tumble within the blast chamber on a rubber or steel flight type belt) Available in load capacities ranging from 1.5 cu. ft. to 24 cu. ft.
  • Spinner Hanger Blast Machines (Work piece is hung from a fixture within the blast chamber) Available in a variety of sizes.
  • Dual Chamber Spinner Hangers (System offers two indexing work chambers so unloading may occur while the second chamber is in the blasting process)
  • Table Blasters (Ideal for large heavy parts. Pieces are placed on a rotating work table for a versatile and efficient blasting process)
  • Hanger Table Blasters
  • Wire Mesh Belt Blasters

The Process

As opposed to an air blast process which employs compressed air to blast centrifugal wheel blasting propels a metallic type of abrasive (steel grit, steel shot, stainless shot or cut wire, zinc)
against the work piece to clean, etch, or peen. This versatile process is perfect for large and heavy parts or batches of small components requiring a consistent finish at very fast time cycles.
Commonly found in a variety of industrial settings it is perfect for high production high volume batches of parts.

In addition to equipment sales, remember that Finishing Systems is your source for the variety of abrasives used in these machines.

Remember, Finishing Systems’ job shop has a variety of centrifugal wheel blasting machines to service customers who have the demand for this type of finishing but do not want to invest in the equipment.

With the cylindrical movement of the mechanism, or the tumbling motion of a Tumble blast machine every side of your parts is exposed to the blast pattern for an even finish.
Other than the loading and off-loading there is no manual work required for this automated type of blasting process – making it highly efficient and cost-effective.

These are a few applications and industries ideally suited for centrifugal wheel blasting:

  • Heavy Industry
  • OEM Manufacturers
  • Steel Foundries
  • Steel Fabricators
  • Sand Casting Foundries
  • Construction
  • Surface Prep
  • Plastics Manufacturing Mold Cleaning

Types of Wheel Blasting

The machine uses centrifugal force to clean parts or give them a finish, but the movement alone cannot do that. There must be another force added to the machine to get the look you need. There are two types of wheel blasting — ones that use an abrasive and ones that use compressed air.

When you use an abrasive, like glass beads or aluminum oxide, the grains push up against the items inside to give them the desired finish. Different types of additives will give different final looks to the items. Motorized blast wheels move the abrasive around in the machine.

The other type of wheel blasting uses compressed air instead of an abrasive. The air moves at a high velocity to achieve the finished look. This type is typically used for items that are more fragile.
