In the process of long-term use, ultrafine pulverizer may encounter a series of common problems. These problems include, but are not limited to, the following:

1. Problems related to motors and bearings

Increased motor temperature: This may be caused by long-term continuous work, damage to the motor bearing, unbalanced rotating part of the motor, etc. Countermeasures include stopping work to cool the motor, replacing damaged bearings, adjusting equipment parameters to balance motor rotation, etc.

Bearing overheating: Bearing overheating is often associated with factors such as poor lubrication, damage, spindle bending, severe rotor imbalance, or overtight belts. Solutions include adding or replacing lubricating oil, replacing bearings or spindles, balancing the rotor, and adjusting belt tightness.

Second, the crushing effect and efficiency issues

Uneven crushing: This may be caused by damage to the blade, unstable motor speed, or asymmetry of the material inlet powder storage port. Solutions include replacing worn blades, adjusting motor speed, and ensuring symmetry between material inlet and powder storage.

Reduction of grinding efficiency: The decrease in grinding efficiency may be caused by high humidity of materials, strong viscosity of materials, tool wear, screen blockage, etc. Countermeasures include adjusting the moisture of the material, replacing worn knives, cleaning clogged screens, etc.

3. Mechanical and operational issues

Feed back-spray: This phenomenon may be caused by improper adjustment of the damper, blockage of the conveying pipe, blockage of the sieve hole, too short powder bag or poor air permeability. Solutions include adjusting the damper, removing blockages, replacing the powder bag, etc.

Strong vibration of the machine: Strong vibration may be related to factors such as the wrong arrangement of hammer installation, excessive weight deviation of the corresponding two sets of hammers, damage to the bearing or bending of the spindle, loose foot connection screws, etc. Solutions include rearranging the hammer blades, balancing the weight of the weights, replacing damaged bearings or spindles, tightening the foot connection screws, etc.

Abnormal noise of the machine: The abnormal noise may be caused by the damage or falling off of the parts in the crusher, or the entry of hard objects such as stones and iron into the machine. At this time, the machine should be stopped immediately for inspection, replacement of damaged parts or removal of hard objects.

4. Other frequently asked questions

Excessive noise: Excessive noise may be caused by abnormal motors, loose equipment parts, etc. The solution includes checking whether the parts of the equipment are loose, checking whether the motor and equipment parts are in good condition, etc.

Improper cleaning and maintenance: Long-term failure to clean and maintain equipment can lead to degraded equipment performance and frequent failures. Therefore, the external surface and internal grinding chamber of the ultrafine pulverizer should be cleaned regularly, the working site around the equipment should be cleaned, and the wear and tear of the electrical system and various components of the equipment should be checked.

To sum up, there are many problems that may be encountered during the use of ultrafine pulverizers. In order to maintain the good performance and stable operation of the equipment, it is necessary to carry out regular cleaning and maintenance work, and pay attention to the operation status of the equipment, and find and solve problems in time.
