Analysis of the situation of the falling of the separator of the Clinker Grinding Mill
The Clinker Grinding Mill is a mill type machine that requires a large crushing hardness. The higher the hardness of the raw material, the greater the damage to the machine. The long-term operation of the Clinker Grinding Mill will cause the fastener to loosen, which in turn causes some accessories to fall off, and the separator blade is dropped. So what should we do in the face of the separator blade drop? Let's look at the analysis given by the SBM machine engineer!
Clinker Grinding Mill separator blade drop reason
1. The common phenomenon is that the Clinker Grinding Mill has long-term operation and large vibrations. The vibration damage to the machine itself is very serious. Once the vibration of the machine body is obvious, it should be dealt with in time to prevent safety hazards and machine failure. . The main causes of machine vibration failure are unreasonable system parameters, equipment body damage, material properties, etc. It is necessary to find and quickly deal with the fault source in time to avoid the falling off of the Clinker Grinding Mill separator blades.
2. Another common reason is that the blades of the Clinker Grinding Mill separator are fixed on the vertical shaft of the separator by the lock nut. The motor of the separator drives the vertical shaft to rotate, and the vertical shaft drives the rotating body integral with the separator blade to rotate. In this case, periodically check the rotating body to see if the lock nut is loose. Once it is loose, it will be processed immediately. This detail is always neglected when it stops grinding, but the maintenance personnel must be careful and cannot ignore it.
How to judge the falling of the Clinker Grinding Mill separator blade
1. When the machine is being operated, how do you find out that the separator blades of the Clinker Grinding Mill have fallen?
When the vibration of the Clinker Grinding Mill is found to be more and more obvious, the temperature of the outlet material rises, and the pressure difference of the Clinker Grinding Mill is reduced. At this time, the inner layer of the Clinker Grinding Mill is thin, forcing the operator to add a large amount of material to ensure the movement. The crusher is stable. Indicates that the blade at this time may have fallen.
Typical case analysis of Clinker Grinding Mill separator blade drop:
Typical case one
The operation of the Clinker Grinding Mill before the blade falls: the feeding amount is 147 t/h, the inlet fan current is 340 A, the raw material vertical grinding system fineness is 16.8%, the circulating fan current is about 90 A, and the separator current It is 27 A and the current changes as the speed of the separator is adjusted.
The operation of the Clinker Grinding Mill after the blade falls: the feeding amount is up to 168 t/h, the inlet fan current is 389 A, the raw material fineness is 28.9%, and the circulating fan current is 112 A. The current of the separator becomes 23 A, and the current of the separator does not change when the speed of the separator is adjusted.
According to this phenomenon, it is indicated that the blades of the separator are no longer rotated with the rotation of the bearing, that is, no load is working. If we encounter this situation in the operation, we should stop grinding in time to prevent the raw material with coarser fineness from entering the raw material storage, which will affect the calcination of the ore rotary kiln.
Typical case two
The sound of the Clinker Grinding Mill is due to the impact of the blade and the rotating body when it falls on the triangular frame. It is seen that the vertical axis is still rotating outside the vertical mill, but the actual grinding inspection reveals that the rotor and the rotor on the circulating rotor have been separated from the vertical shaft and landed on the triangular frame in the Clinker Grinding Mill.
In summary, it is not difficult to find the bad situation of the Clinker Grinding Mill. It is difficult for us to carefully observe and discover. Only in this way can we find the problem in time, solve the problem, and kill the problem in the cradle to ensure Our Clinker Grinding Mill works fine!
