What is the mill?

The rod mill is grinding ore that uses a number of free steel bars in a rotating drum to ensure its wear or grinding. The red charge of the ore is added to the drum and as it turns, friction between the plastered rods breaks the ore down to finer particles. Although it is similar in operation, the rod mill is often more efficient than a ball mill, because to achieve the same results requires lower rotary and less steel speeds. However, it is limited to the maximum length of the rod and drum approximately 20 feet (6 meters) and is generally used only for wet grinding processes. The rod mill also tends to suffer from the accelerated insert of the drum and wear the jack due to the increased weight of the rods.

Mills of various types have been used for centuries to break solids or coarse particle materials for finer finished products. From modest mortar and thickness to animal, wind and water -powered mills to giant electrically driven versions common in modern Industurial applications, all share one common characteristic: Mechaniccut or grinding. All types of mills use the process of grinding one or the other description to gradually reduce the size of the initial material charge. For example, in older mills, this action was achieved by placing a rough material between two mills and turning one against the other to create a finer terminal product.

Modern rotary mills create the same principle by plastering free sanding elements around in a closed drum to which the material is charged. Common examples are rod and ball mills that are from the type of rotary drum that rely on internal abrasive agents to achieve their milling action. Unlike a spherical mill, which uses a large number of hardened steel balls to lend a cut effect, the mill uses the rod lying in the drum and parallel to its axis. When a drum rotoBeates, these rods roll around inside,thus crushed the feed material between them.

The

rod mill is generally more efficient than a ball mill due to its more effective cascading effect and a larger bearing surface of the offered rod. This means that it can work at lower speeds with smaller grinding substances and produce less undesirable by -product. However, during the operation, they require more attention to avoid tangling the rod and generally are generally ineffective in dry milling operations. They are also limited to a maximum rod length of approximately 20 feet (6 meters), which means they are generally smaller than spherical mills. Mills also shows more wear of the insert and jack than other types of mills due to the relatively high weight of the rods.
