Ore Milling Machinery

Ore milling machinery is used at different stages of mining to obtain it in different forms. To begin with it undergoes primary crushing that reduces the rock to pebble size. At this stage it is introduced to ball or rod mill where it is reduced to powder form. From here starts the action of the chemical milling that separates the metal from the ore.

Though this remains the general process, the type of machinery varies with mineral properties like hardness, brittleness, abrasive qualities, chemical stability, purity etc. Generally, the harder the material, the better the mill required is the rule.

Different types of ore milling machinery

Autogenous mills consists of a large diameter, short length cylinder with lifting bars. The product to be introduced needs to be coarse but be disintegrated to small sizes.

Rod Mills are loaded with steel rods placed axially in the mill and are free to move within the mill. They are used for very hard materials usually during the first stage of a milling process

Ball Mills are similar to the rod mill but have steel balls instead of rods. It is a versatile grinding mill and has a wide range of applications.

Roller Mills are of two types first is a series of rollers which rotate around a central axis within a drum and the second is where there are a series of fixed rollers and a rotating table. They are used for softer minerals.

Hammer mills have a set of hammers that rotate in a vertical or horizontal plane. They can be fixed or swinging types. They can convert the product to very fine powder.
