Our main product series are ball mill liners, wear parts forcrushers and grinding media. Boltless Ball Mill Liners decreasemaintenance of liners and save the cost of bolts. What???s more,our boltless-liner design can exert the maximum quenching hardnessof metal material while the bolted-liner design has to scarify thequenching hardness to get better toughness because each bolt holeis a source of thousands of crackings.
??Our foundry has complete melting, heat treatment and testequipments, such as mid-frequency induction??electrical furnaces,quenching and tempering furnaces, blast shot, spectrometer,Rockwell and Brinell Hardness tester, impactor, UT tester andmetallographic microscope. We achieved the certificate of qualitymanagement system ISO 9001:2000. We have been exporting castings tooversea markets, such as Brazil, Australia and South Africa.
