The proven classical option for cement grinding. Whether employed as a two-compartment separator mill in an independent grinding system, or in combination with a high pressure grinding roll, the Ball Mill is a robust and reliable alternative for cement and granulated blast furnace slag grinding.
The particle shape of the materials from the roller press and the vertical roller mill is also different. The vertical mill grinds the material by two forces, the extrusion force and the shearing force between the roller and the grinding disc; the roller press grinds the material by only one force, the force between the two grinding rollers.

The speed of rotation of the mill. At low speeds of rotation, the balls simply roll over one another and little crushing action is obtained. At slightly higher speeds, the balls are projected short distances across the mill, and at still higher speeds they are thrown greater distances and considerable wear of the lining of the mill takes place.

Ball race mill (Peters-mill of the Claudius Peters Joint Stock Company, Hamburg, Germany). The cement industry employs the Peters-mill (pre viously called Fuller-Peters-mill) mostly for coal grinding. It is a few years now that the shockproof construction (shock resistance – 3.5 bar) of the Peters-mill was designed for coal grinding.
An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that.
According to different grinding systems, the often-used cement mills include ball mill, roller press, and vertical roller mill. In addition to the cement mill, other commonly used equipments in the cement grinding station include cement mill separators, bag filters and ESPs, cement silos, conveyors, bucket elevators, cement roto packers, etc.
In the cement industry, high-pressure grinding rolls have proven their worth - not least due to their low energy requirements - and have been used worldwide for decades for grinding cement raw material, cement clinker, and granulated blastfurnace slag.
