Abrasive Blasting

Media

Blasting media comes in many different

grit sizes and sometimes also rated as

extra fine, fine, medium, coarse, and

extra coarse. The larger the grit

number, the smaller the particle size;

the smaller the grit number, the larger

the particle size. Glass media can come

in beads, crushed, or ground.

Aluminum oxide and silicon carbide can

come in several colors. It is common

today to find mixtures of glass and

aluminum oxide.

Available commercial abrasive blasting media

Abrasive media - not

recommended

Although available, some media are

not recommended for use because of

mechanical and/or personal hazards.

Silica sand, a common blast media, has

health risk concerns due to the silica

content. Restriction on its usage is

common in many states.

Beach sand (play sand) is a common

and inexpensive blast media. This

highly aggressive media can have

debris mixed in which will cause

clogging of equipment.

Steel grit produces ideal surface

preparation on new coating. This

media should only be used in a special

blast cabinet designed for this media.

Steel shot, a round, solid particle,

leaves a dimples in a surface after

blasting. It is a very dense media and

should only be used in a special blast

cabinet designed for this media.

Common abrasive

media

The more commonly available media

and their uses are listed below.

Walnut shell is one of the most

versatile organic media due to its

angular, durable shape. It is still

considered a soft media, but it is good

to use on delicate parts. Use as an

economical, bio-degradable alternative

for sensitive blasting that will not

scratch or damage surfaces.

Glass beads are the most popular all-

purpose media used today. Used for

honing, polishing, peening, blending,

finishing, removing light burrs, frosting

glass, and cleaning most light

materials. Common uses in the removal

of paint, rust, and surface residues.

Glass bead blasting generally will not

change the dimensions of the item

being blasted. Glass beads produce

brighter finish than angular abrasives.

Beads can be recycled and used many

times.

Crushed glass is very aggressive. Used

for economical, general clean-up.

Plastic is available in a variety of sizes

and materials (urea, acrylic, polyester,

and melamine). These materials are

ideal for application such as auto

restoration to deliver a high stripping

rate without damaging or warping the

substrate material.

Brown aluminum oxide is a widely used

abrasive media. This media produces a

textured surface, good for repairing

surfaces for recoating. It is excellent for

removing heavy foreign materials,

deburring, and etching glass and stone.

It is a fast-cutting media that can be

reused many times.

White aluminum oxide can be used in

the same applications as the brown

aluminum oxide, but white aluminum

oxide is considered to be a clean

media, used in high performance

processes where contamination of

metal oxide must be kept to a

minimum.

Aluminum / glass mixtures provides a

combination of glass bead finishing

and aluminum oxide cleaning. It

provides a brighter finish than single

abrasives, and it is good for removing

rust and machine marks on metal.

Silicon carbide is the hardest Abrasive

material available. It is fast cutting and

can be reused many times. It is high in

initial cost, but removes material

quickly to reduce blasting time.

Fonctionnement

Lea estas instrucciones de

funcionamiento antes de enviar aire al

tanque de la chorreadora. Siga estas

instrucciones después de haber

completado el ensamblaje de la unidad.

1. Coloque la válvula esférica de

mango azul y las dos válvulas

esféricas de mango rojo en la

posición completamente cerrada

(ver figuras 5, 6 y 7).

2. Ajuste la presión de aire deseada en

el regulador de la fuente de aire.

No supere los 125 psi.

3. Conecte la manguera de aire de la

fuente de aire a la válvula esférica

de mango azul.

4. Mientras hala el mango en T

(ver figura 8), abra por completo la

válvula esférica de mango azul (ver

figura 9). El aire comprimido llenará

el tanque y el filtro.

Nota: El modelo MXS21001 no tiene

el mango en T; en su lugar, tiene un

tornillo en la tapa metálica (ver

figura 10).

5. Abra la válvula de mango rojo en la

parte de atrás del tanque. Esto

permite que el aire comprimido

ingrese a la manguera del material

y a la pistola chorreadora (ver

figura 6).

6. Verifique que no hayan fugas.

Si encontrara fugas de aire, gire la

válvula esférica de mango azul en la

posición completamente cerrada y

deje que el aire purgue del tanque.

Una vez descargado el aire del

tanque, repare las fugas y vuelva a

colocar la válvula esférica de mango

rojo en la posición completamente

cerrada.

7. Después de reparar las fugas, hale

el mango en T y coloque la válvula

esférica de mango azul en la

posición completamente abierta.

8. Verifique otra vez que no haya

fugas; repita el procedimiento si

fuese necesario.

9. Verifique la válvula de seguridad

halando el anillo de la válvula de

seguridad (ver figura 11). La válvula

dejará salir un flujo de aire fuerte y

continuo. Observe el manómetro

del tanque: la presión de aire

debería disminuir. Si entra más aire

de la que sale por la válvula de

seguridad, la válvula de seguridad

está bloqueada y debe

reemplazarse. Cambie la válvula de

seguridad con un repuesto idéntico.
