Roller Rock Phosphate Grinding Mill Detail

Failure analysis of Roller Rock Phosphate Grinding Mill

The leakage of slurry in the seal of Roller Rock Phosphate Grinding Mill used in concentrator will cause a series of problems, such as inner wall corrosion and ceramic tile burning. Many users don’t know how to solve it after they encounter it. In fact, slurry leakage of Roller Rock Phosphate Grinding Mill is a very common problem, but it is not inevitable. The leakage is mainly caused by the daily maintenance of the equipment. In order to prevent the leakage of the Roller Rock Phosphate Grinding Mill during the construction process, we can prevent the leakage of the Roller Rock Phosphate Grinding Mill in advance through technical methods. Today, we sort out the common leakage problems of the Roller Rock Phosphate Grinding Mill, and summarize the prevention methods of each problem.

1. Leakage between Roller Rock Phosphate Grinding Mill feed pipe and feed Bush

In general, the sealing device of conventional Roller Rock Phosphate Grinding Mill equipment adopts packing sealing. During operation, the feed chute is in a static state, but when the Roller Rock Phosphate Grinding Mill barrel is located in the tank, the feed bushing is connected with the tank to rotate. When the liquid level is higher than the lower level of the feed inlet, the slurry will enter the connection between the feed chute and the feed sleeve, resulting in the leakage of the feed inlet.

In addition, the feed bushing is always rotating during use, and long-term rotation will cause packing wear. When the wear is serious, the sealing effect will be lost, resulting in slurry leakage.

In view of the above leakage problems, we can prevent leakage in advance through the following three steps:

2. Slurry between feed sleeve and Roller Rock Phosphate Grinding Mill end cover

There are two types of sealing bushes and end caps for Roller Rock Phosphate Grinding Mills:

One is a three plate packing seal, one end of which is located by the inlet sleeve and the end of the end cover, and the sleeve is in full contact with the flange on the end cover, and it is fastened by bolts, but the two have friction with each other, and the other end is sealed by redundant packing. During assembly and operation, if the position of the mouth is not good or the package is worn, the Roller Rock Phosphate Grinding Mill will leak.

The second is a tapered seal. The end of the seal is the same as the packing of the packing. It is positioned by the stop, and the other end is positioned and sealed by the extrusion of the conical gasket. However, unlike the packing seal, the feed bushing and the end cap are different. Flange connections require a gap of 3 to 4 mm so that there is no friction between the flange surfaces of the bushing and the end cap, which does not deform due to long-term rotation, causing the attachment bolts to move, resulting in leakage of the cone seal.

For the above leakage problems, the preventive measures are as follows:

The sealing method of three-way packing can improve the machining accuracy of the feed bushing and end cover flange surface by abrasive belt grinding. In addition, an O-ring can be installed on the flange surface of the paper feed end cover. The groove is provided with an O-type seal on the flange connection surface between the feed bushing and the feed end cover, which realizes double sealing, thus solving the problem of slurry leakage.

For the conical seal structure, we do not recommend using this type of seal, mainly because the connecting bolts of the seal feed Bush and the end cover are easy to break, and slurry leakage often occurs.
