Ball Mills vs Rod Mills

When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force

Ball Mills - an overview ScienceDirect Topics

2.10.3 The Performance of Ball Mill Relative to Vertical Mills. Comminution in ball mills and vertical mills differs fundamentally. In a ball mill, size reduction takes place by impact and attrition. In a vertical mill the bed of material is subject to such a high pressure that individual particles within the bed are fractured, even though the particles are very much smaller than the

Ball Mill - an overview ScienceDirect Topics

The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in ...

What Is a Ball Mill? - Monroe Engineering

10/03/2020  Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, less-coarse medium.

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A section cut thru of ball mills. A ball mill consists of a hollow cylindrical shell rotating ...

Rod mills, how they function - Mine Engineer.Com

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of ...

The working principle of ball mill - Meetyou Carbide

22/05/2019  The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact and grind the material in the cylinder to grind ...

Comparing Used Ball Mills Vs Used Rod Mills

In a ball mill the actual balls in the machine need to cascade in order for the grinding to be accomplished. Because of this more energy is needed to power up a ball press as opposed to a rod press. Rod mills can be operated at lower peripheral speeds resulting in reduced energy costs. Though this difference in power can vary depending on the type of ore you are grinding the consensus is that ...

As can be seen the samplings campaigns revealed a higher k parameter for the vertical mill in comparison to the ball mills sampled. This parameter represents the slope of the grinding curve which means the higher k, the easier to grind the material (or better performance for a grinding . 8 circuit). Therefore, the vertical mill showed performance significant better than the ball mills
