What are the reasons for the failure of the shot blasting machine?

First, the steel on the conveying roller table has crawling phenomenon:

     1) The roller chain is too loose

     2) The roller shafts are biased in the same direction

     3) The output chain of the roller table motor is loose

Second, the reasons why the shot blasting quality cannot be achieved:

     1) Fewer projectiles

     2) The workpiece is seriously corroded or stained

     3) The amount of shot blasting is not enough

     4) The particle size of the pellets is not suitable

     5) The projectile area is unreasonable

     6) The pellets are agglomerated or used for a long time

     7) The conveying speed of the roller conveyor is too fast

Third, the efficiency of dust removal and separation is low:

     1) The air volume is not enough

     2) The cloth bag sticks too much dust

     3) Broken bag

     4) The pellets are unevenly distributed during separation

Fourth, the bucket elevator does not operate:

     1) stuck

     2) Belt slipping

Fifth, the vertical and horizontal spirals do not work:

     1) Blockage of pellets

     2) The screw shaft is out of sync with the motor

     3) The spiral shaft is bent

     4) The welding seam of the spiral shaft head is broken

Sixth, the shot blaster has abnormal noise:

     1) The projectile does not meet the requirements

     2) There are larger granular materials in the pellets

     3) The guard plate of the shot blasting machine is loose

     4) The combination disc bolts are loose

Seventh, the vibration of the shot blasting machine is relatively large:

     1) The blades are severely worn and unbalanced

     2) The impeller body is seriously worn

     3) The bearing is burnt out

Eighth, the projectile fly out from the entrance or exit:

1) The sealing curtain is broken

2) The shot blasting angle is wrong

Ninth, there are too many steel shots on the surface of the workpiece:

1) The height of the cleaning device is not coordinated with the workpiece

2) The angle between the high-pressure blow nozzle and the workpiece is not coordinated
