Performance Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture.
The feed enters one end of the ball mill, and discharges out the other end. Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock ...

The rod mill is a grinding mill that utilizes steel rods as the grinding medium in the cylinder. It is commonly used in various industries such as ore dressing, machinery, and chemical industries to grind a variety of brittle materials and ores. The rod mill offers several advantages, including high yield and uniform discharging size, making it ...
Rod mill for sand making. A rod mill is a mill in which the grinding body loaded in the cylinder is a steel rod. Rod mills are generally of wet overflow type, which can be used as primary opencircuit grinding, and are widely used in primary grinding of artificial stone sand, mineral processing plants, and power departments of chemical plants.
The preflotation treatment generally begins at the rodmill. A cleaning agent such as sodium silicofluoride, trisodium phosphate, or sodium sulphide with sodium hydroxide is added with the fine crushed ore to the rod mill and grinding is accomplished with a dilute pulp (2535% solids).

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

The ball mill is a key equipment for grinding materials, widely used in powdermaking production line such as cement, silicate sand, newtype building material, refractory material, fertilizer, ore dressing of ferrous metal and nonferrous metal, glass ceramics, etc. Ball mill can grind various ores and materials with dry type or wet type.
The ore is ground into a fine powder by large rotating mills. The two types used in the Mission South Mill are called SAG (semiautogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well.
