VIBRATORY MILL Russian patent published in 2013 - IPC B02C19/00 

FIELD: process engineering.

SUBSTANCE: invention relates to grinders to be used in construction, mining, food or chemical industry. Proposed mill comprises grinding tube 1 with grinding bodies 2 fitted with the help of resilient elements 3 at fixed bed 4 and equipped with two unbalanced vibration generators 5. Every generator 5 comprises drive shaft 6 with separate rotary drive to vary angular velocity and sign of rotation of shaft 6 and unbalances 8 fitted on drive shaft 6. Note here that said unbalanced vibration generators 5 are fitted diametrically opposite the sidewalls of grinding tube 1 in plane 9 of transverse symmetry of grinding tube 1. Rotational axes of unbalances 8 are located perpendicular to the plane of transverse symmetry of grinding tube 1.

EFFECT: higher grinding efficiency.
