However, the timing of heat treatment can vary when using a thread ground ball screw. This is because thread grinding allows the thread to be cut even after heat treating, it is preferred that heat treatment is performed prior to grinding, to ensure that the sizes and lead accuracy will not change due to the heat treatment.
temperatures Ac 1,Ac 3 and Ms were measured to be (719, 739 and 254) °C, respectively. Figure 1 shows the manu facturing of 125 mm grinding balls. Table 1 shows the heat treatment of the grinding balls. The surface temperature of a grinding ball was

Larger grinding media has a smaller grinding surface area, but offers a heavier weight that''s generally used to break larger ore. Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller. In some cases, we find ourselves adjusting the ball size by the millimeter to approach optimization.
The heat treatment of Forged Grinding Ball is the process of heat, keep warm, then cool down, cooled at different speeds. It can not be interrupted in this process. Heat treatment process is also one of the important factors to ensure the quality of Grinding Balls.
The casting defects will also have detrimental effects on both impact and abrasion resistance of the grinding ball. The impact fatigue resistance is very important and needs to be controlled by a proper heat treatment step. Or else the repeated impact of the grinding balls may cause one (or more) of the following to happen to the ball:
Heat treatment furnace for grinding balls: Heat treatment process is the last process for producing cast grinding media mill different chrome content in grinding balls,the heat treatment technology is different. Middle casting grinding media balls and low chrome casting grinding media balls .
