Newly Arrival 6 Inch Steel Ball - Grinding ball – Junda Detail:

Producing process

After checking and testing the round alloy steel bar material,the production can be started according to the size of the steel ball . The steel forging is heated to a certain temperature by intermediating with frequency furnace to ensure the effective generation of variables in the forging;  The red-hot steel forging is sent into the air hammer and processed by skilled operators.  After forging the red hot steel ball immediately into JUNDA specially designed heat treatment equipment for quenching and tempering heat treatment, the high and uniform hardness value of the steel ball can be ensured.

Feature

1.High impact toughness

2.Compact organization

3.High wear resistance

4.Low breakage rate

5.Uniform hardness

6.No deformation

Remark

1.JD SG4-4 series is a special supporting device for JD pressure sandblasting machine.
2. Adjust the degree of tightness of outer joint can in a way adjust the spinning speed of spinning nozzle holder. And the speed should be controlled within 30~500r/min.
3.If spinning nozzle holder stops spinning or spinning too slowly, it may be because of under pressure, too tight outer joint, stuck bearings or jamed nozzle. Stop the machine, and then adjust and check.
4.Before working,pipeline in wall sandblaster should be put in the in wall from one side to another, and dry pressed air must be inlet. When working, blasting pipe should be pulled out slowly to make it get out at a constant speed. If the cleaning quality can’t meet the requirements, work again to get the satisfactory effect.
5.If the abrasives are blocked and can not be sprayed out, it should be closed down first and exhaust, then have a check. 6). Quick-wear parts should be checked regularly,they should be replaced timely if worn, or they would have a bad influence on the efficiency and the blasting quality,and maybe Exhaust bring accidents
