What do You Want to Know about Ore Rod Mill?

The so called rod mill is named because the grinding media inside the cylinder are steel bars. Generally speaking, MBS rod mill can be divided into wet type rod mill and dry type rod mill according to rod milling process, which is suitable for primary grinding in ore processing plant, chemical plant, electro powder department and so on.

Ore rod mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills. Ball mill machine is an efficient tool for grinding many materials into fine powder.




Rod mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the 'Critical Speed', and ball mills usually operate at 65% to 75% of the critical speed.

The ball grinding mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.
