Q1: For achieving maximum capacity of the ball mill, the ball charge should be equal to about __________ percent of the ball mill volume.

ANS:C - 50

For achieving maximum capacity of a ball mill, the ball charge should typically be around 50% of the mill volume. Here’s why:

• The ball charge refers to the grinding media (balls) that are loaded into the ball mill for grinding purposes.
• The optimal ball charge ensures that the mill is loaded with the correct amount of grinding media, which is essential for efficient operation and maximum grinding capacity.

While the exact percentage can vary depending on the type of mill and specific operating conditions, a ball charge of around 50% of the mill volume is a common guideline for achieving maximum capacity without overloading the mill or reducing grinding efficiency.
