WhatsApp: +86 18838072829The balls (Ø 20 mm) reduce the machining chips to a coarse powder. Then balls (Ø 6 mm) formed spherical morphology in the powders with particle sizes ranging from 38 μm to 150 μm (60 h). The ballmilled powder produced from machining chips has a 56% greater hardness than the gasatomized powder.

WhatsApp: +86 18838072829Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
