What are the common faults of flat die granulator?

Flat die granulator is a kind of equipment widely used in granule manufacturing, but some faults may be encountered during use. Understanding these faults will help timely repair and maintenance to ensure the smooth progress of production.

1. Uneven granulation

This is a common problem. It may be caused by uneven humidity of the raw materials. If the raw materials are partially too wet, it is difficult to form regular particles during the granulation process. In addition, large differences in the particle size of the raw materials or uneven mixing of the materials will also make the granulation effect uneven.

2. Mold wear

After a long period of operation, the flat die and the pressure roller of the flat die granulator are constantly squeezed and rubbed by the materials, and will gradually wear out. Once the mold is worn, it will cause irregular particle shape and reduced output.

3. Poor feeding

Poor feeding is also one of the common faults. It may be that the feed port is blocked, often because the material is mixed with large lumps or the viscosity of the material is too large. This will not only affect the continuity of granulation, but also cause the machine to run idle and waste energy.

4. Transmission component failure

The transmission components of the flat die granulator are also prone to failure. For example, if the bearing lacks regular lubrication, it will wear out more, resulting in abnormal noise and vibration. This vibration not only affects the stability of the equipment, but may also further cause other components to loosen or damage.

5. Electrical system failure

Electrical failures sometimes also trouble the normal operation of the flat die granulator. For example, motor failure may cause the equipment to fail to start or suddenly stop working. Short circuits or open circuits in the circuit will cause the control system of the equipment to fail and affect the normal operation of the equipment.

Through these measures, the occurrence of failures can be effectively reduced and the operating efficiency and product quality of the flat die granulator can be improved.
