The Dictionary Says:
Force of grit thrown at a high velocity to clean millscale from metal surfaces. b.
A machine (Wheelabrator) used to abrade metal surfaces. 2.
A strong velocity carrying sand/grit along. 3.
Mechanical or automated sandblasting
The Machine - Puget Sound Coatings can load

Wheelabrator, with brand new millscaled steel, at one end and it comes out the
other end clean and scale free. It also works to remove paint, rust and other types of
We specialize in running new full length (Standard 21' - 60') pipe as
well as raw steel through our wheelabrator in preparation for
Hot Dip Galvanizing.
The machine has capability of running longer length things that are as wide
a 6-feet and as tall as 16-inches. Rather it be Plate, I-Beam, H-Beam, Piling,
Angle, Pipe, Tube or Flat Bar all parts roll through the machine on rollers.
While the parts go through the middle of the machine there are four wheels,
heavy motor driven that look similar to a water wheel that are turning at a very
high rate of speed. The media drops onto the wheels paddles and is then
flung from the wheel at a very high velocity at the
part going through. This action cleans the surface right down to it's bare substrate
material to any of the common
grades of cleaning. The most common types of media we use for our wheelabrator is Steel Shot &
The Media Used In The Wheelabrator
is the same as gets used in the blasting booths. Listed next is the description
of those material types:
Steel Shot - A manufactured material from the steel industry where an
atomization process (Click
here for an interesting detail on how Steel Shot and Grit is made) to create
small droplets that in further process becomes silver in color and is available in a large variety of
sizes from the very small 200 to the very large number 8. Because of the ability
different levels of steel hardness it has a wide range on the Moh's Hardness chart of usually between
8 - 10. Most steel shot material is made at the harder
side which makes it nearly indestructible for the blasting industry and where we
can literally get hundreds of throws before it turns to dust. This material is
most commonly used because of the dimpled surface texture it leaves on the
Steel Grit - Similar to steel shot except in the angular grit form. The
color and the hardness is also similar to the the shot however the impact on the
item being blasted is much different. With shot you get a dimple effect where as
grit you get a divot. This material is greatly used to remove the mill-scale on
steel for coating preparations. It is a very aggressive blast media and cuts
Our technicians carefully choose which material needs to be added along with
what rate the part being cleaned should travel through the machinery as well as
the paddle wheel speeds to achieve the best finish possible for the customers
specific needs on each and every job we put through our facilities.
