The ball mill is a horizontal type and tubular running, has two warehouses. It runs along the outside gear. Materials spirally and evenly enter the first warehouse along the input hollow axis by input devices. In the ball mill' warehouse, there is a ladder scale board or ripple scale board. Steel balls of different specifications are installed in the scale board. When the barrel body rotates, centrifugal force is produced. At the same time, the steel balls are carried to some height and then fall to grind and strike the material. After being grinded coarsely in the first warehouse, the material then enters into the second warehouse for regrinding. In the end, the powder is discharges by output material
There are different types of ball mills; of course, iron ore mill prices vary due to their unique specifications and applications. Autogenous grinding uses coarse pieces of the ore itself as the grinding media in the mill. Semi-autogenous operations use metallic balls and/or rods to supplement the grinding action of the ore pieces. Autogenous grinding is best suited to weakly cemented ores containing some hard material (e.g., labrador specularite). The benefit of autogenous grinding is that it is less labor- and capital-intensive. Semi-autogenous grinding eliminates the need for a secondary crushing circuit. Rod and ball wear, the principal maintenance cost of traditional grinders, is also eliminated with this method.
This machine is a horizontal cylinder rotary device which can be installed on base ground once and forever. The main bearing with double roller bearings can save energy by 30%, improve fineness, and increase processing energy by 15-20%. Through material hollow shaft spiral the material is sent to the first mill chamber, in which there are ladder liners or corrugated linings, with steel balls of different specifications in it. When cylinder is rotating, centrifugal force will make steel ball fall down from a certain height, thus impacting and grinding the materials. After coarse grinding in the first chamber, materials enter into the second chamber through a single diaphragm. In this warehouse with flat lining board and steel balls in it, materials are further grinded.
