VIBRATION GRINDER Russian patent published in 2016 - IPC B02C19/00 

FIELD: vibration equipment.

SUBSTANCE: invention relates to vibration equipment and can be used for lumps and loose materials grinding and milling. Vibration grinder comprises working member, means of resonant progressive circular oscillations communication to which is isotropic resilient suspension in form of cylindrical rods, by which it is connected to fixed base, and rotary pendulum exciter driven to rotation in vertical plane by drive shaft. Resonance tuning of resonant progressive circular oscillations communication devices is defined by resonance combination parametric relationship ω = λ₁+ λ₂, where ω is parametric excitation frequency (rotary pendulum exciter speed), λ₁ = vω is pendulums oscillations partial natural frequency, v - dimensionless parameter determining pendulums oscillations partial natural frequency in rotary coordinates system (0<v<1), $${\lambda }_2={\lambda }_{2x}={\lambda }_{2y}=\sqrt{C/M_0}$$ is working element partial natural frequency corresponding to vibrations circular shape, C = C_x = C_y is isotropic resilient rod suspension rigidity, M₀ is machine working member weight.

EFFECT: higher quality of raw material grinding.
