Finally, while a ball mill will have a recirculation factor of 2 to 3, these increases between 6 to 20 for a vertical roller mill, depending on the pressure height, the grinding tools configuration, the grind ability of the material and the required product fineness. 4

Get Price29.5% in both the chambers. Both the chambers of the cement mill were charged with 80% of the designed charge, which works out to 86 t in Ist chamber and 172 t in the IInd chamber. The mill is utilised for production of OPC 33 grade, OPC 53 grade and PPC. The blaines for the cements of different grades are being maintained as given below:
Get PriceThe working principle is that cement is removed from the mill before over-grinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. Recirculation factor, that is, the ratio of mill throughput to fresh feed is up to three

Get PriceRe: Cement mill Residue. Dear Mr Jatin, You have not mentioned circuit of your mill.I assume that it might be a closed circuit cement mill. Best possible way to reduce residue on 45micron is by increasing circulation factor across the mill.The other way is to decrese cut size of your dynamic separator by increasing cage rotor speed
Get PriceFeb 21, 2015 Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70)

Get Priceutes. Individual cement particles will be ground from one to three times in a VRM before being offered to the classifier, whereas repeat grinding in a ball mill is virtually uncounta-ble because of the grinding mechanism. Finally, while a ball mill will have a recirculation factor of 2 to 3, this increases
