What can cause the fluctuation on Cement separator speed while the mill is running? News Date:2015-09-14 14:18:47. To check drive would be the first choice. Also mechanical aspects: gear and shaft. Some frequency drives can lower the speed as function of the torque. Therefore, you should check if there has been an increase in power consumption.
grinding plant, separator speed and fresh feed are the main control parameters. The MPC controller frequently calculates new set points for the two parameters. The calculation is based on minimizing a so called "cost-function" meaning minimum deviation from production targets and minimum changes of separator speed and fresh feed.
Today's greatly increased demands on cement quality, particularly on its strength, induced Phoenix to equip cement grinding plant 1 with a new separator, a rotor separator with transversely inflowing separating air. It was decided to install a high-efficiency separator, the QDK 29-NZ from Christian Pfeiffer (Tables 1 and 2).
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
In the OK mill, parameters such as mill air flow, separator speed and grinding pressure can be easily adjusted during operation to control or adjust the PSD curve to a steeper or flatter profile that achieves. Get Price Or Chat Online. Fcb Cement Mill Separator.
Jan 07, 2015· Raw mills usually operate at 72-74% critical speed and cement mills at 74-76%. 3.2 Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2*3.14*(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm. 7.
Product quality is a function of cement particle size distribution (PSD) and the dehydration of the gypsum within the cement. In the OK mill, parameters, such as mill air flow, separator speed and grinding pressure, can be easily adjusted during operation to control or alter the PSD curve to a profile (steeper or flatter) that achieves the ...
The ball mill is the key equipment to crush the material after being crushed. This type of mill is equipped with a number of steel balls in its cylinder as grinding medium. It is widely used in cement, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal beneficiation and glass and ceramics industries.

a 4.4 m diameter x 15.25 m two-chamber ball mill that is now used mainly for the production of CEM II/A-LL 32,5 R cement. The cement is ground to finenesses correspond- ing to 3100 to 4800 cm2/g Blaine. The modernization of the separator, which took only a few weeks, achieved significant improvements in throughput and specific energy demand.
Athematical separator performance evaluation Cemen. Separators in the cement industry have the task of separating coarse from fine material, and it is worthwhile to fully understand the function of separators in raw and cement mills Consequent troubleshooting, the elimination of technical barriers and optimum processing will result in an increase in the final product of the mill
A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball mill/third-generation separator, CKP/ball mill/third-generation separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption.
In cement production, major economic gains are being made by optimising milling, both of the cement and of replacement materials, using at- and on-line instruments. Fig.2 shows a schematic of a typical finishing circuit used to reduce the particle size of the cement to .
