Ball Mill Sudden Failure Solutions

Ball Mill For Ceramics Sudden Failure Solutions

In cement production industry, ball mill is a kind of very important grinding equipment. Besides, ball mill is also very important in beneficiation plants. But in the working process of ball mill, sometimes there will be sudden failures.

Knowing how to deal with these failures will greatly reduce the downtime and save production cost for investors. So in this article, we mainly talk about sudden failures of ball mill and their solutions.

Ball Mill Sudden Failure And Solutions

Sudden Heat Of Reducer

When the reducer of ball mill suddenly heat, it might because the cooling system works not so good. While grinding clinker, the high temperature clinker will lead to the increasing of temperature of the reducer. In the cooling process, the cooling water will form much incrustant piling up in the inwall of pipe. In this case, water through the pipe will reduce, so the temperature of reducer will increase. To solve this problem, operators need to clean the incrustant in the pipe firstly and then cut off the water and then filter it. After this, send the water to the reducer in order to decrease its temperature.

Loosen And Part Of Screws Connect The Quill Shaft And Shell

Generally, the connection of quill shaft and shell is that quill shaft connects the flange and the flange connects the shell. And they are connected by screw bolts. But in the operation process, because of deformation, thermal expansion, high temperature and corrosion, the screw bolts will loosen. After long term operation, the screw bolts will part. To solve this problem, we can replace half of the screw bolts with hinged pin.

Temperature Of Sleeve Bearing Increases Rapidly And Loud Sound In The Transmission Part

When the temperature of sleeve bearings increases rapidly and there is loud sound in the transmission part, this is because the grinding head sinks. In this case, the grinding mill moves forward and tilts. This will not only reduce the capacity but also produce friction. To solve this problem, operators should lengthen the weld of the foundation bolts and lift the bearing seat, making the shell keep balance.

Actually, in the working process, every machine may have some sudden failure or even accident. And some of these problems cannot be solved easily, so operators should take measures according to the local working condition and repair the broken parts as soon as possible.
