process of ball milling
Ball milling, a shearforce dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO2) or steel balls), acting as grinding media and rotating shell to create centrifugal force

The ball milling speed is the speed of the stirring shaft of the ball mill Under the condition of low speed, medium speed, and high speed, the ball milling process can mix, compound, and crush the sample powders, respectively
The results of signaltonoise analysis obtained the optimum parameter values in a row are: 100 rpm for milling speed parameter, 15: 1 for BPR parameter and 120 minutes for timemiling parameter The powder size experiment verification of the ball mill process optimization parameter is
The ball milling process of 250−300 rpm ball milling speeds and 5−7 hours ball milling times are worth recommending based on α, which causes an increase by 95–100 % in σ yc and a decrease by 30–35 % in CTE compared with 2024Al alloy respectively
