Answer (1 of 2): Mills are defined by the type of grinding media (balls, rods or the ore itself), their physical dimensions (length and diameter), and power input, not by the material that they are used to process. The selection of a particular mill for a particular purpose depends on the physi...
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency [5] Autogenous mill

"Milling" must be differentiated with "grinding" because it is different in the software. "Grinding" is what we are all used to: diamond burs grinding off material in planes to make the shape and ending with one sprue. "Milling" is using carbide burs to cut into the block with a punching motion.
Attrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.
Ball mill is a kind of grinding mill that uses steel balls or ceramic balls as grinding media to grind materials. Ball mill is widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, and glass ceramics. The ball mill is suitable for grinding various ores and other materials.
Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in …
Grinding mills are size reductions machines that often follow crushers in the processes where finer products are desired after crushing. 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.
Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
Ball mill and rod mill are suitable for different materials. 1. Selection by material's hardness. Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2.

The difference of Raymond Mill and Hige pressure grinding mill, Suspension Roller Grinding Mill, YGM grinding Mill . As the saying goes,"There is no harm without comparison." Raymond mill is a commonly used machine for milling equipment. After the improvement, Raymond mill, also called high pressure grinding mill and suspension roller grinding mill, which can grind high hardness materials.
Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.

Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes. Various kinds of mills are there with which different material processing takes place.
Grinding time is related to media diameter and agitator speed via: T = KD 2 /N 1/2. where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm. This equation shows that total grinding time is directly ...
