Abstract

The application relates to the technical field of sand making machines, in particular to a high-efficiency low-noise sand making machine and a use method thereof, which comprises a box body, the surface of the box body is provided with a sound absorption assembly. The application has the advantages of noise reduction and multiple crushing modes. In the actual use process, the introduction of the noise reduction design greatly improves the noise reduction performance. The metal fiber layer one is combined with the nano sound absorption layer one and the nano sound absorption layer two to form a high-efficiency sound absorption structure, sound wave energy is effectively absorbed, the perforated aluminum plate and the graphene foam sound absorption layer further reduce noise, the pleated wall sandwich barrier significantly consumes sound wave energy through multiple reflection and scattering, and finally, the stainless steel skin effectively blocks external noise. This design significantly reduces noise propagation and reflection, provides excellent sound insulation effect for the box body, effectively reduces the noise level, and creates a more quiet and peaceful working environment for the operators.
