The energy saving cone ball mill is a key grinding machine to grind the crushed materials and it is widely used in powder-making production line including cement, silicate, new-type building material, refractory, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and it can grind various ores and other materials with dry type and wet type. There are two kinds of energy saving cone ball mills: grate type and overfall type due to different discharging ways.
The ball mill, a grate one, is a horizontal cylinder rotating device driven by gears with two silos. The materials get into the first silo through the feeding quill shaft from the feeding device spirally and evenly. There are ladder lining board or corrugated lining board in the first silo loaded with steel balls of different sizes. The centrifugal force produced by the rotation of the cylinder raises the steel balls to a certain height which then fall down, thus making a thumping and abrading to the materials. After the coarse grinding in the first silo, the materials get into the second silo through the monolayer partition panel with flat lining board embedded with steel sections for further crushing. The powder of the materials will be discharged from the unloading board to finish the grinding work.
