2 Principles and Applications of Metal Rolling (ii) Shape of the rolled product- flat, sections or hollow sections rolling. (iii) Direction of rolling- lengthwise, transverse, and skew rolling. (iv) Mode of rolling mill operation- continuous (unidirectional), and reverse rolling, where direction of rotation of rolls are reversed. When two rolls of equal diameter and …

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

Rod mills need careful monitoring as the rods must remain nearly parallel to avoid tangling and reduced grinding efficiency. The maximum rod length typically reaches around 6.1 meters (20 feet), which limits the length, diameter, and capacity of rod mills. Additionally, larger rods can lead to increased wear on mill liners and loaders. Pebble Mills

The cylinder length to diameter ratio of rod mills is generally between 1.5 ~ 2.0, and the inner surface of the lining plate on the end cover is in a vertical plane state. 5. Different equipment performance Ball mill.

Vertical ball mills are not commonly used in industries due to their capacity limitation and specific structure. A vertical roller mill comes in the form of an erect cylinder rather than a horizontal type like a detachable drum. ... rod mills, and ball mills for the subsequent treatment. Over a period of many years of development, the fine ...

In such cases the open end low discharge principal is accomplished by means …

Ball Mills vs Rod Mills - 911 Metallurgist

The variation of a with ball diameter was found to be of the form a = k2/d1.5. Both k1 and k2 vary with mill diameter, and simple power laws have been assumed, k1 ∝ D0.1, k2 ∝ D0.6. If it is ...

Rolling is a metal forming process in which the deformation takes place under the application of Compressive forces between the rollers. In this article, we are going to discuss a detailed presentation on the Rolling Process with its Principle, Working, Types of Rolling Mills, Advantages, Disadvantages & Applications.

Rod Mills are similar with the Ball Mills xcept 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 ...
