Company Profile
SHANGDONG SHENGYE GRINDING BALL CO.,LTD specializes in the production of grinding medial ball for ball mill. Staff are trained and selected by strict overseas technology . The quality of grinding meida ball is consistent and the specifications are complete. The annual output of diameter DIA 20MM-DIA 150MM grinding media ball is 100000 tons.
Due to the application of internationally advanced technology and manufacture experience ,our grinding media balls have the advantages of rubbing endurance, crashing tolerance and roundness persistence ,compared to other products in this field. We record the data for our grinding balls, follow up customers and drop in services at calling to solve customers' uncertainties.
Testing Equipment
We have a first-class laboratory and equipped with advanced testing equipment to ensure the quality:
Spectrometer--The wear resistance of grinding media ball is mainly determined by its chemical composition.
Hardness tester-- Testing the surface hardness of grinding media ball.
Laser cutting machine-- Cuting the core of grinding media 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 media ball.
Drop tester--Testing the service life of the grinding media ball.
