Impeller

Crystals Group is a manufacturer and supplier of Impellers for shot blasting machine applications. Also known as Accelerators or Dispensers, these components form part of the blast wheel assembly and help accelerate abrasive media onto the blade surface.

What is an Impeller?

An impeller is a component of the blast wheel assembly that accelerates abrasive media through the control cage opening and directs it onto the blade surface. It provides the initial acceleration or velocity to the abrasive before it reaches the blades.

The correct fitment and positioning of the impeller play an important role in the performance of the wheel assembly.

Why is Impeller Positioning Important?

The positioning of the impeller is important for maintaining a smooth flow of abrasive media onto the blade surface. Two key parameters should be considered when installing an impeller.

The leading edge of the impeller should always be positioned approximately one-third ahead of the blade surface. This positioning facilitates the smooth flow of abrasive media onto the blade.

The centre of the impeller should also be aligned with the centre of the control cage and barewheel. Incorrect alignment can result in uneven wear of the blade set.

Impeller for Shot Blasting Machines

Impellers work as part of the blast wheel assembly along with components such as the control cage, blades and barewheel. Their function is to provide initial acceleration to the abrasive media before it reaches the blade surface.

Proper fitment and alignment are therefore important considerations when installing an impeller in a shot blasting machine.

Manufacturing of Impellers

Crystals Group manufactures impellers using a specially developed alloy casting composition and Shell molding process. The components have a uniform finish and are manufactured for use in shot blasting wheel assemblies.
