How does this Silent High Speed Coffee Grinder maintain a silent effect when grinding at high speed? Does it use special noise reduction technology?

The body of the Silent High Speed Coffee Grinder is made of heavy cast aluminum, which not only has excellent stability and durability, but also plays a key role in reducing vibration and noise transmission due to its high density and excellent sound absorption characteristics. The cast aluminum body is precisely processed and the internal structure is reasonably designed, which effectively avoids additional noise caused by loose or unreasonable structure.
The blade is a 74mm specially hardened flat blade imported from Ltay. Its hardening treatment not only significantly improves the durability and grinding efficiency of the blade, but also reduces friction and collision during grinding by optimizing the structure and shape of the blade, thereby reducing noise. The balance design of the blade is also carefully adjusted to ensure stability when rotating at high speed, further reducing vibration and noise caused by imbalance.
A variety of sound insulation materials are used inside the grinder, such as sound-absorbing cotton, sound insulation board, etc., which can effectively absorb and isolate the noise generated during the grinding process and prevent it from spreading outward. The internal structure is compact and well designed, which reduces the reflection and resonance of noise in the body, thereby reducing the overall noise level.
This grinder may use ACF metamaterial vibration reduction and noise reduction technology or other similar advanced noise reduction technologies. These technologies can withstand large forces and deformations through special materials and structural designs while maintaining stable performance, effectively reducing the noise level of the grinder. Some high-end models may also be equipped with an active noise reduction system, which can offset noise by emitting sound waves in the opposite phase of the noise to achieve more efficient noise reduction.
The motor and transmission system of the grinder are carefully designed and optimized to reduce vibration and noise during operation. The motor uses a high-performance silent motor, which runs smoothly and has low noise. The transmission system uses a precision gear and bearing design to ensure smooth power transmission and low noise.
The outer shell of the grinder may adopt a double-layer or multi-layer structure design, with sound insulation material filled in the middle to further isolate the noise. The base of the grinder may be equipped with shock-absorbing pads or shock-absorbing feet to reduce noise caused by ground vibration.
