Blast machine is a kind of mechanical equipment, make the use of compressed air
as its power, spraying different kinds of abrasive
materials(metallic and nonmetallic) onvto the surface of workpiece
for impacting grinding, getting rid of foreign matters and dithered
color and oxide layer. At the same time, it can be used for
roughening of the surface and increasing of the superficial area.
Thus, the adhesion of the coating can be improved to produce the
strongest acid and alkaline resistance properties for upgrading
coating quality. Meanwhile, decreasing of residual stress on the
surface of the basic material and increasing the surface hardness
of the basic material.
According to the blasting way, blast machine can be subdivided into
pressure feed type and suction type. Because the pressure feed type
is mixing of compressed air and abrasives while blasting in the
same container, the compressed air can be utilized sufficiently and
both air flow and sand flow are easy to regulate.
It not only can apply to large area treatment, but also can blast
small components. At present KPB series and AC series produced by
SHLIANSHI ENTERPRISE belong to pressure feed type blast machine.
Its control mode can be subdivided into three series namely manual
control, pneumatic and electrical control, more than thirty models
In addition, the pressure feed type and suction type sand blast
cabinet applied to light industry and non-standard automatic blast
machine can be custom-built according to the user’s requirement.
Typical function：rust removal, cleaning mill scale; eliminate oil and residual
stress and increase of surface roughness (Ra0.5-150um) and
clealiness (Sa2.5 class) of the work piece, shot peening forming
Typically be applied to surface treatment of marble material:
instead of burning process; heighten efficiency; control pattern
Typically be applied to metallic roller: on line without stopping
machine, it will operate smoothly, conveniently and
Typically be applied to mould: thoroughly smoothly high efficient
cleaning and environmentally.
Typically be applied to clothes for post treatment: the dye layer
on the textile surface can be gotten rid of by utilizing the
sandblasting to wash and its efficiency is higher than any other
For detailed application chapter, each division of SHLIANSHI
ENTERPRISE has arranged and filed for your requisition.
Shot blast machine：
1. Shot blast classification: shot blast is divided into three
types according to the application rangecleaning shot blastng ②shot
blast strengthening ③shot blast formation. When browsing files or
technical files, the shot blast” word always shows, the strict
meaning is: adopt compressed air as drive source to peen out the
shots, which is called shot peening”; adopt rotating impeller blade
to blast the shots, which is called shot blasting”, no matter what
methods are adopted, the desired purchase is the same.
2. The difference between shot blast strengthening and cleaning
shot blasting: the former is under control of shot blasting
technique, the parameters of the latter are not changed except the
time; the purpose of the former is to increase the fatigue
strength, the purpose of the latter is to remove surface oxide
layer to improve the surface quality. The strengthening shot blast
is called "shot blast strengthening", "stress shot blasting".
3. shot blast strengthening: the shot blast strengthening is a very
traditional surface strengthening technique. The principle is: by
virtue of shot impacting on the surface of work piece at high
speed, to make it elastic plastic deformed, so as to produce good
changes of residual stress and work hardening, increase the bent/
twist fatigue strength and improve stress corrosion cracking
