Rod Mill with Good Price for Mining ... - ball mills supplier

Overflow rod mill is the most common mining rod mill model. The product particle size is finer than the other two rod mills, generally used to grind the crushed products, and then provide it to the ball mill for further grinding. End peripheral ore discharge rod mill. The discharge end of this mining rod mill is located at the end of the barrel.

Differences And Similarities Between Rod Mills And Ball ...

The grinding fineness of the ball mill is finer, usually the output particle size is between 0.074-0.4mm, while the output fineness of the rod mill is between 0.833-0.147mm. 4.Classification is different. Ball mills can be divided into overflow-type and lattice-type ball mills, while rod mills are classified into overflow-type and open-type rod ...

Rod Mill - an overview | ScienceDirect Topics

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.

What is a Rod Mill? (with picture) - Info Bloom

Common examples are rod and ball mills, both of which are of the rotary drum type which rely on internal grinding agents to achieve their milling action. Unlike the ball mill which utilizes a large number of hardened steel balls to impart the grinding action, the rod mill uses steel rods lying within the drum and parallel to its axis.
