In general, the ATOX50 vertical mill mainframe is 3500kw, because the material grindability of our factory is poor, and when it becomes worse, the ability of the vertical mill will be reduced and can only be forced to reduce the material operation, otherwise it will cause the vibration of the vertical mill and cause the operation instability.
VIBRATION STUDIES OF CEMENT MILL Steps for vibration measurements Impact test was carried out at selected locations on the torsion bar to know its natural frequency Normal vibration signatures were recorded with motor speed being 994 rpm and pinion speed 122 rpm Vibration data was recorded on selected bearing locations of motor, gearbox and ...
Mar 01, 2016· re vibration vertical roller mill. There are a number of reasons for high vibrations in vertical roller mills, such as: 1. Failure of the grout or cement material under the steel beams embedded in the foundation top, which allows oil to penetrate, further degrading the concrete.
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

Our OK Mill grinding solution skilfully comminutes raw material, cement and slag. You can easily adjust it to grind any feed material and produce multiple cement types in the same mill. Due to its highly effective drying performance, the OK Mill is the natural choice for .
• cement industry: Nghi Son, Vietnam, 1998,Guangzhou, China, 2005. Loesche developed the 4-roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The develop-ment was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
In the present case study, the causes of the high vibrations on a double-drive cement mill is investigated by performing a series of vibration measurements on the cement mill pinion and the main ...
In this paper, vibration characteristics of a Vertical Roller Mill (VRM) are studied by using physical parameters of an operating VRM. The mathematical model is derived and simulated for a set of ...
Why cement grinding ball mill is floating towards the Gear box (MAAG) which has resulted the damage of the second stage of gear box. As we have replaced the gear box now but still we are unable to find out the solution how to control the mill which is continue its floating towards gear box.
