The main shaft of the spiral classifier is prone to breakage, which is likely caused by these reason

The spiral classifier is a commonly used ore processing equipment in the mining industry. For the spiral classifier, the machine mainly deals with hard materials such as stone, so the wear of the machine is also serious in the process of processing ore. Especially the wear of the spiral classifier's bearings. The problem of spiral classifier bearing fracture often occurs at the processing site. Qidong Zhuoya will tell you what are the reasons for the fracture of spiral classifier bearings.

1. The spiral classifier has too much rotation load

The rotation load of the spiral classifier is closely related to the amount of incoming materials. When the amount of incoming materials is too much or too coarse, the rotation load of the spiral classifier increases. Long-term high-load operation can easily fatigue the hollow shaft of the spiral classifier, leading to twisting and breaking. At the same time, when the slurry entering the classifier directly washes on the hollow shaft, the hollow shaft is easily impacted and worn, increasing the risk of hollow bearing breakage.

2. The small shaft of the lower support bearing of the spiral classifier is worn

When the small bearing shaft of the lower support is worn, it will cause abnormal vibration of the hollow shaft. If the situation is serious, the small bearing shaft of the lower support will break, and the hollow shaft of the spiral classifier will lack fixed support, which will lead to bending and breaking.

3. The coupling of the motor reducer of the spiral classifier is not correct

The misalignment of the motor reducer coupling can also be divided into misalignment of the horizontal shaft coupling, misalignment of the large and small bevel gears, and severe wear of the transmission support copper washers. These situations will cause abnormal vibration of the hollow shaft, and long-term existence will affect the service life of the hollow shaft.
