The different levels of cutter heads of garbage disposers determine the fineness of grinding food residues.

The grinding level of a garbage disposal plays a crucial role in its processing effect. The grinding level mainly determines the fineness to which food residue is ground. The finer the food residue is ground, the less likely it is to clog the drain, reducing the frequency and difficulty of maintenance and cleaning.

Common grinding levels include 3-stage grinding, 5 - stage grinding, 7 - stage grinding, etc.

• Level 3 Grinding: Commonly found on the market, the basic model uses a 360-degree rotating impact head on the cutter disc for preliminary grinding, and then performs secondary grinding on the edge of the cutter disc through centrifugal force and the pushing action of the cutter head.
• Level 5 Grinding: An auxiliary disc is embedded below the 3-stage cutter disc to further grind the food waste, making the waste more finely divided.
• Level 7 Grinding: On the basis of 5 - stage grinding, another flat - surface grinding cutter disc is added, so that the waste is directly processed into a solution state, which is more conducive to discharge and the dredging of sewers.
