Most of the tonnage milled today is ground in one of the following types of equipment or a combination of two or more ball mills, tube mills, rod mills, and stamps. Chilean mills and Huntington mills are used only in a few isolated cases today.Get A Quote
All types of Ore Grinding Mills that consist essentially of rotating cylinders with flat or conical ends with balls, pebbles, or rods used as grinding media are included here.
The term ball mill is generally used to refer to a cylindrical mill whose length is less than, equal to, but not much greater than its diameter. It was initially developed for relatively coarse grinding, but by using it in closed circuit with a classifier its use has been extended for fine grinding.
Ball mills have shells of cast iron or steel plates and are carried on hollow trunnions. Ore is fed through a scoop, drum-type, or combination feeder at one end and is discharged from the opposite trunnion.
Ball mills are built in sies ranging from small laboratory mills to a present maximum of 12 ft. diameter by 12 ft. long, the latter requiring close to 1000 hp.Liners are usually of manganese steel, of chrome steel, or white iron, 3 to 6 in. thick. Corrugated and shiplap construction is commonly used to increase the grinding action.
The Hardinge mill see Fig. 16 differs from most ball mills in that conical ends are added to the cylindrical portion of the mill. The cone at the feed end has a larger open angle than that at theopposite end. Its makers state that the large balls concentrate near the feed end of the mill where the coarsest ore collects and the smaller balls act on the finer ore.

May 10, 2019nbsp018332The grinding efficiency is reflected in the processing capacity of the mill and the fineness of the grinding ore. Large diameter steel ball help reduces grinding time thus improves grinding efficiency, in addition, putting some small steel ball to control the particle fineness effectively.
The grinding efficiency is the most important parameter to evaluate machine performance. This article discussed the factors that influence grinding efficiency including article sie to mill machinemilling mediumslurry rheological propertiesunderflow ratiolinergrinding aid etc. The mill machine should be automatically controlled at a high level.
The grinding efficiency is reflected in the processing capacity of the mill and the fineness of the grinding ore. Large diameter steel ball help reduces grinding time thus improves grinding efficiency, in addition, putting some small steel ball to control the particle fineness effectively.In fact, the steel balls are continuously worn and the straight diameter is gradually smaller, so it is difficult to guarantee the ratio of the diameter of the steel ball to keep a stable level.
The liner plays the role of protecting the cylinder and end cover of the mill and lifting the grinding medium. The shape and material of liner have a great influence on the steel consumption of grinding. In addition to the traditional manganese steel liner, there are rubber liner and magnetic liner.
