Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor. The paper will propose …
②Fine crushing equipment, such as ball mill, rod mill, etc.; ③Ultra-fine grinding equipment, such as centrifugal mill, stirring mill, jet mill, sand mill and Raymond mill, etc. According to whether the grinding medium is used or not, it can be divided into: ①There are media grinding equipment, such as ball mills and sand mills;
Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.
