patent and started selling an improved version of this mill all over the world. For the cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding.  · How much steel fiber is added to a concrete mix depends on the objectives: cost savings, increased joint spacing, or structural improvement. Steel fiber dosages can be as light as 8 pounds to as much as 200 pounds per cubic yard. Increasing the percentage of fibers in a mix allows specifiers to increase the distance between joints.

CEMENT TREATMENT (ROAD-MIXED)

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
