Material Guarantee Grinding Ball Manufacturer

Certificate of analysis

l Steel certificate must be delivered to HY with batches of steel

l The inspection department must confirm that the steel certificate and steel bar label are the same

lThe heating number in the material certificate is linked to the HY document in the file for customer tracking

Production Management System

Air hammer forged grinding balls Hot rolled grinding balls

Mechanical properties of grinding balls

*Steel: low carbon steel, high carbon manganese alloy steel, high manganese alloy steel.

* Consistent surface hardness and core hardness (58-65HRC)

*Grinding balls achieve high impact toughness of over 15J/cm2

*Minimum damage rate: 125mm grinding ball damage rate reaches "0" and all the damage rate is less than 0.5%

*Improved wear rate and toughness maximizes mining grinding efficiency and saves costs

Ball grinding quality control system

QC Teamwork: With over 10 years of experience in the industry, team workers will test each batch of grinding balls before production and inspection and before delivery (surface and core hardness tests, impact values, etc. will be recorded to different steel heating numbers for future tracking)

Ball mill ball

Packaging system

Bag: Grinding balls can be packaged in woven bags, each bag of 1000 kg. Efforts on pallets and loading

Steel barrel: The grinding balls should be installed in a steel barrel with an open top (with threads) and the barrel should be installed on a pallet made of heat-treated wood or plywood. Two drums per tray

HY's technical director has more than 30 years of experience in the grinding industry. All technical teams are professional workers in the forging industry, studying abrasive improvements and heat treatment technologies in different industries. In development, our abrasive ball quality is recognized in gold mines, Cooper Mining, cement plants and other related industries.
--------How to improve the wear resistance of grinding balls to help you reduce costs
>Customized Raw Materials - Purchase qualified raw materials from well-known and standard steel mills in China. The quality of the grinding steel ball is directly related to the raw materials. The matching of chemical components plays a key role in the performance of steel balls. Each batch of steel that leaves the factory will be inspected and comply with the steel mill certification. All qualified steel will be recorded and can be tracked through heating numbers within 5 years.
>The advanced hot rolling production line combined with traditional manual forging allows HY to provide all specifications of DIA20-150mm grinding balls, maintaining stable grinding efficiency.
>The unique heat treatment technology greatly affects the quality of the grinding balls. Improve surface and volume hardness, hardness uniformity and toughness
> A strict quality control system will be followed in every order during the production process and afterwards. Our Quality Control System allows nearly 95% of the balls to be inspected before loading on board, reducing the risk of buying.
