The artificial graphite disperser is mainly used to uniformly disperse artificial graphite particles into liquid media, and is widely used in the production fields of battery materials, conductive coatings, etc. During the operation of the equipment, various problems are prone to occur due to factors such as material status, operation mode, and component loss. If not dealt with in a timely manner, it will affect the dispersion quality and production progress. The following are common problems and solutions:

The common problems and solutions during the operation of the artificial graphite disperser are as follows:

1. Uneven mixing

Performance: Uneven distribution of graphite particles and poor mixing effect.

Reason: Unreasonable design of the mixing blade, installation position deviation or severe wear, improper speed setting.

Solution:

　　•Replace or redesign the mixing blade to ensure it matches the material characteristics;

　　•Adjust the installation position to a reasonable height to avoid eccentricity;

　　•Optimize the rotational speed parameters based on graphite viscosity.

2. Excessive vibration of the equipment

Performance: Abnormal vibration and noticeable noise during operation.

Reason: Unstable foundation, worn transmission components (such as bearings and gears), or unbalanced mixing blades.

Solution:

　　•Re calibrate the equipment level and reinforce the foundation;

　　•Check and replace worn bearings and gears to ensure good lubrication;

　　•Conduct a dynamic balance test on the stirring blade.

3. Abnormal temperature control

Performance: The temperature of the motor or material is too high.

Reason: Cooling system malfunction, motor overload, or high material viscosity.

Solution:

　　•Clean the cooling water pipeline and check the heat dissipation device;

　　•Reduce the load or replace the high-power motor;

　　•Adjust the graphite slurry ratio to reduce viscosity.

4. Sealing leakage

Performance: Graphite slurry seeps out from the sealed area.

Reason: Aging of seals, improper installation, or long-term wear and tear of equipment.

Solution:

　　•Replace corrosion-resistant sealing materials (such as polytetrafluoroethylene);

　　•Reinstall the seal to ensure even clamping force;

　　•Regularly check the wear of the sealing surface.

5. Motor malfunction

Performance: Difficulty starting, overheating, or unstable speed.

Reason: Voltage fluctuations, bearing wear or insulation aging.

Solution:

　　•Check the stability of the power supply and install a voltage regulator;

　　•Replace motor bearings and regularly maintain lubrication;

　　•Check the insulation performance of the winding and repair it if necessary.

preventive measures

‌•Regular maintenance: check the transmission system, lubrication status, and seals;

‌•Operating standards: Avoid overloading operation and adjust parameters according to material characteristics;

‌•Accessory selection: Use wear-resistant and corrosion-resistant mixing blades and sealing materials.
