QUALITY AND RELIABILITY RIGHT FROM THE START
BENEFITS FROM LOESCHE GRINDING PLANTS

The energy-efficient grinding principle and the reduced use of natural resources.
Advantages of Loesche mills important in the light of increasing plant size
and the obligation to make more careful use of primary energy.

Sohag – LOESCHE is involved in the new construction of a large cement plant in Egypt with three vertical roller mills. The end customer is the Egyptian Cement for Cement Projects Management S.A.E. The planned new plant is located nearly 500 km south of Cairo in Sohag.

The LOESCHE scope of delivery includes a raw material mill with a capacity of 540 t/h of cement raw meal, a cement mill with an output of 350 t/h of clinker as well as a coal mill with an output of 45 t/h.

CEMENT RAW MATERIALS - PLANT SIZES

The coordinates of the grinding table diameter and number of rollers can be read off from the table. The x-coordinate indicates which product throughputs can be generated using the respective mills. The width of the fields is a measurement of the output factor.

The dimensions H, A and D in turn describe the height of mills with classifier, the footprint diameters and the overall space required, taking a service area (for replacing grinding parts) into consideration.

Mill sizes are identified according to the outer effective diameter of the grinding track in decimetres [dm]. The identification is followed by a digit, separated by a full stop. This specifies the number of rollers operated in the mill.

The number and size of rollers is geared to the required product throughput in conjunction with the “Loesche performance factor” as well as the product which is influenced by factors of grindability, moisture and fineness. The required gas stream is decisive for the housing dimensioning of mill and classifier.
