Carbide ball - carbide wear-resisting principle

When the Tungsten Carbide Balls T.C.Ball  mill ball loading with trace relative slide, ball mill parts contact surface temperature, oxidation was accelerated. By experiment, the energy released during the process of fretting wear, most consumed in the form of heat. Ball mill ball micromotion abrasion area often appear fatigue crack. But due to the contact stress produced in ball mill only on the surface of the steel ball wear play, these cracks are generally not expanding, just in the ball mill steel ball surface pitting or play a flake. Under overloading, or micro amplitude is high enough, the cracks may also be extended.


Under the fretting wear of steel Tungsten Carbide Ball Carbide Balls for ball mill is a kind of difficult to completely eliminate the phenomenon of wear. But take measures can reduce the degree of wear and tear. Reduce the micro contact area; Ball mill ball instead of the whole structure; Contact part of the table and hardening (increase the surface hardness and surface in the compressive stress state); 14 steel ball mill finish; Surface spraying hard metal; Steel boronization, chromizing, permeability vanadium, carburizing, nitriding; Increase the contact stress of the steel ball mill or increasing the friction between the contact surface; Join the high elastic strain limit between ball mill ball contact area of material to absorb micro amplitude, are measures to prevent of the fretting wear of steel ball mill.

Six Star Hardmetal are one of few real can produce Tungsten Carbide Balls  from 0.5mm to 72mm T.C.Ball  manufacturers in China.
