This machine is suitable synthetic resin, apparatus, chemicals and other materials in micro-grinding machines, shredders generally it is different not only using force of impact and shear force of a simple smash smash, also used the blade on the back of ultrasound generated numerous vortex, and the resulting high-frequency vibration stress the role of the material crushed, under certain conditions, with viscosity and elasticity can also be crushed. Local raw materials in the crushing operation in the temperature rose very little, so the heat-sensitive material can also be crushed.
