0.5-1.5 m/min Processing Speed Q6910 H beam and Steel Plate Shot
Blasting Machine Roller Conveyor Abrator
1. Q6910 Shot blasting machine Application:
Q6910 shot blasting machine is a specially designed machine used in
the surface cleaning for various jobs. It can realize the shot
2. Q69 Shot blasting machine Components and function:
Q6910 shot blasting machine consists of roller conveyor system,
blasting system, abrasive circulation system (separator, bucket
elevator, screw conveyor), dust collection system, and electric
control system. The surface finish level is Sa2.5.
2.1 Conveyor system
It consists of loading and unloading rollers, chamber rollers,
● Rollers in the blasting cabinet are protected by special alloy
jacket with lifetime over 4,000 hours.
● Conveyor system is driven by motors with inverter. Rollers can be
controlled manually and automatically.
● Step-less speed is available. Roller conveyor could move in step
with the whole machine or move faster.
2.2 Shot blasting system
Shot blasting system consists of auxiliary chambers, blasting
chamber and shot blasting machine assembly. The abrasive media like
the steel shots, grits are applied on the metal surface driven by
the centrifugal force from the blades. Workpieces will be
de-rusted, cleaned and roughened in blasting system to reach
customer’s finishing level.
2.2.1 Auxiliary chamber
There are 5-7 layers of wear-resisting rubber curtain in it. The
suspension type makes the exchange and access easier. The seal
ability is excellent. No dust would be leaked out because of the
negative pressure formed by the dust collector fan.
2.2.2 Blasting chamber
In the blasting chamber, the wall is protected by SPMn13 material
liner and 65Mn protective liner, which has high wear resistant
performance. Chamber inside protection plate all adopt the high
strength nut fixed and pressure on the inner of blasting chamber,
easy tear open outfit replacement. Prolong service life, reduce the
cost and reduce maintenance frequency. The steel abrasive fall down
freely and collected by screw conveyor.
2.2.3 Shot blasting machine assembly
This machine has 10 sets of high speed & performance blast
wheels. Material of blades, control cage and distributor is Cr20S
high-chromium, which has long service life. The lifetime of blade
is over 500 hours, and lifetime of impeller and control cage is
over 2000 hours. All wear parts are the market most universal
national standard parts.
2.3 Abrasive circulation system
The system includes following parts: hopper, abrasive control
valves, screw conveyors, bucket elevator, separator.
2.3.1 Screw conveyor
Screw conveyor consists of cycloid needle wheel decelerator, screw
axis, conveyor shell, bearing, etc. It is a
standard conveying device and an important part of abrasive
circulating system. The screw blade is made of 16 Mn.
This unit is responsible for conveying the abrasive to the
elevator. Screw conveyor located at the bottom of shot blasting
chamber, the spiral blade welding in the drive shaft. Conveyor
motor drives screw conveyor to send abrasive to discharge outlet,
then the mixed abrasive will be conveyed to elevator bottom.
On both ends of the screw conveyor adopt triple seal protection.
the abrasive and dust will drop to the clearance between end plate
and bearing once leak out, will not enter the bearing. Screw
conveyor shaft with sensors detecting unit can detect the working
