                                          Production Process

1.Material Inspection
Custom the raw materials -- testing the chemical composition of raw materials -- Put the qualified steel material into workshop            


2. Forging or Hot rolling
Put the raw materials into the intermediate frequency furnace and heat them to a certain temperature -- Hammer forged or hot rolled process -- cooling -- Quenching -- Insulation -- tempering

3. Quality Inspection
Testing the impact value -- testing the surface hardness -- cutting the grinding ball by laser cutting machine --testing the core hardness -- Observe the metallographic structure -- testing the forging steel grinding ball fatigue life 

4. Packing and delivery
packing the qualified forging steel grinding ball--Storage--Delivery from factory



                                         Testing Equipment


We have a first-class laboratory and equipped with advanced testing equipment to ensure the quality:

Spectrometer--The wear resistance of forging steel grinding ball is mainly determined by its chemical composition.
Hardness tester-- Testing the surface hardness of grinding ball
Laser cutting machine-- Cuting the core of grinding ball
Impact tester-- Ball mill with a diameter more than 6m, the larger the impact value, the lower the breaking rate. 
Microscope-- Observe the density and structure of grinding ball 
Drop tester--Testing the service life of the grinding ball 



                                         Packing and Delivery

1. Transpotation 
Ocean shipping ( Or Customers designated transportation mode.)

2. Packing Way
