Building material grinding device capable of reducing vibration and noise

The invention belongs to the technical field of building material processing, and relates to a shock-absorbing and noise-reducing building material polishing device which comprises a processing bin internally provided with a polishing assembly, and a sound insulation pad is detachably mounted on the inner wall of the processing bin; a damping base is arranged below the processing bin; the damping base comprises a first bearing plate and a second bearing plate which are sequentially arranged from top to bottom, cushioning pads are detachably installed on the opposite faces of the first bearing plate and the second bearing plate respectively, each cushioning pad comprises a cushioning base plate, and cushioning protrusions are arranged on the opposite faces of the two cushioning base plates. The processing bin serves as a building material polishing space, and a sound insulation pad in the processing bin is beneficial to reducing outward transmission of noise; the two cushioning base plates and the cushioning p
