1 inch - 6 inch Steel Forged Grinding Steel Balls For Gold Mine Cooper Mine

Grinding Steel Balls supply 1-6"forged grinding balls for gold mine,cooper mine

Products introduction

Forged steel ball is divided into carbon grinding steel ball, manganese
grinding steel ball and special grinding steel ball. Forged steel ball is one
of our advantage products. Diameter 20-70mm and 80-150mm steel ball are
produced respectively by advanced automatic hot rolling and hot forging steel
ball production line. Huafu grinding balls with uniform hardness in a high
efficiency due to its advanced quenching technology. In advanced, these
grinding balls feature high accurate dimensions, rounded geometry shape, high
hardness and good mechanical properties, wear - resistance, no deformation, no
breakage.
