Get Price And Support Online; The Processes of Matching the Proper Grinding Balls . The grinding ball is a material grinding media of ball mill and coal mill.

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency [5]

In addition, the surface area per unit volume of the steel bar medium is smaller than that of the steel ball medium, so the utilization coefficient of the rod mill is lower than that of the same simplified diameter ball mill, and it is not suitable for fine grinding equipment.

The principle of Grate Discharge grinding is nearly universally adapted in the cement grinding industry. Grate Discharge Ball Mills are the rule rather than the exception. Rod Mills for raw and finish grinding begin to enter the picture. Larger and larger diameter mills become common. Lengths tend to shorten.

Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill.

Dec 12, 2016· Open circuit grinding to a given surface area requires no more power than closed circuit grinding to the same surface area provided there is no objection to the natural top-size. Rod and ball

Cylpebs of equal diameter and length have 14.5% greater surface area than balls of the same mass, and 9% higher bulk density than steel balls, or 12% higher than cast balls. As a result, for a given charge volume, about 25% more grinding media surface area is available for size reduction when charged with Cylpebs, but the mill would also draw

Ball Mills, Pebble Mills, Material Processing Mills: For more than a century, Patterson has been the industry leading manufacturer of wet and dry grinding mills for size reduction or dispersal. Patterson’s ball, pebble and rod mills are built to last. We are still filling parts requests for mills sold over 60 years ago. Patterson mills are available in a wide variety of standard sizes and

Mar 20, 2017· Ball Mills: -The final stages of comminution are performed in tumbling mills using steel balls as the grinding medium and so designated "ball mills" Since balls have a greater surface area per unit weight than rods, they are better suited for fine finishing.
