A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to extract metal. a rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action. an ore charge is added to the drum, and as it rotates, friction between the.
Different grinding machines are usually named as mills, for example rod mills, ball mills, and attrition mills. because of the name, verb milling is also been used as a synonym for grinding. milling, sometimes also known as fine grinding, pulverizing or comminution, is the process of reducing materials to a powder of fine or very fine size.
At the same time, grinding machines have also developed accordingly, and a ball mill with a wide range of uses appeared in the early 19th century. in 1870, on the basis of ball mill, rod mill with uniform discharge size was developed. in 1908, a.

Mill type overview. three types of mill design are common. the overflow discharge mill is best suited for fine grinding to 75 – 106 microns.; the diaphram or grate discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; the centerperiphery discharge mill has feed reporting from both ends and the product discharges.
Mills grinding. generally ball mills are more common than rod mills or sag mills, there are other types of mills available such as vertical mills but the last three mentioned are by far the most common. ball and mills use steel balls or ceramic balls as their grinding media. rods mills as the name suggest use rods as their grinding media.
The finesse of the material milled by the ball mill is 0.074mm0.4mm, only except for the two small ball mills that have a wider range of 0.0750.89mm. however, the rod mill fine grinding fineness is about 0.8330.147mm. in terms of the fineness.
