Good Wholesale Vendors Zirconia Grinding Media Beads, Yttrium Stabilized Zirconium Oxide Grinding Balls

Short Description:

Junda forged steel ball, relied on advanced equipment and production technology, our forged steel ball has the advantages of high hardness, good wear resistance, no fracture, uniform wear and so on. The forged steel ball Mainly used in various mines, cement plants, power stations, chemical industry and other industries. In order to ensure the excellent performance of grinding ball, we have established a perfect quality testing system, advanced quality control and testing equipment. We have also obtained ISO 9001:2008International quality system certification. Hoping for your cooperation.

Junda company produces φ 20 to φ 150 forged steel balls ,we select high quality round steel,low-carbon alloy,high manganese steel,high carbon and high manganese alloy steel as raw material produced by air hammer forging process. We select high-quality round steel as raw materials, and adopt advanced equipment, unique heat treatment process and strict quality control system to make sure the better performance of forged steel balls in the overall hardness. the surface hardness is up to 58-65HRC, volume hardness is up to 56-64HRC. The hardness distribution is uniform, the impact toughness value is 12J/cm², and the crushing rate is far less than 1%. Forged steel ball chemical composition: carbon content is 0.4-0.85, manganese content is 0.5-1.2, chromium content is 0.05-1.2, We can produce different size according to customer’s request. We have also obtained ISO 9001:2008International quality system certification.

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.

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
