1. Choose a cutting cutter head of a size suitable for the dredger. Size is the primary factor determining whether the cutting cutter head can be used.
2. Consider the parameters of the dredger's working parts to see if the cutting cutter head is compatible with the dredger's operation.
3. Consider the underwater working environment. Due to different underwater soil conditions, different cutting cutter heads are required. There are many types of cutting cutter teeth, and different environments call for different tooth types.
4. There are also various materials for the cutting cutter teeth. It is necessary to understand the underwater working environment to select cutting cutter teeth made of materials that meet the requirements for durability and toughness.
