Grinding in Ball Mills: Modeling and Process Control

The paper presents an overview of the current methodology and practice in modeling and control of the grinding process in industrial ball mills.

Comminution Circuits for Gold Ore Processing

Given that mills are charged to the target ball charge with reasonably sized media, and the feed to the ball-mill circuit is not so coarse as to cause constant scatting, the key to efficient ball-mill circuit operation is efficient classifier operation. The standard classifier for ball-mill circuits is the hydrocyclone.

Winning the Metal: Ore Mills of the West

Stamps were the most common way to crush ore for many decades, but by the first few decades of the 1900s the ball mill started replacing stamps. By the 1930s, many stamp mills were retrofitted with ball crushers, replacing the stamps that were originally used. ... In a 10 year period, the gigantic Consolidated ia Mill processed over ...
