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.
