VIBRATION CLASSIFIER Russian patent published in 2017 - IPC B07B1/40 

FIELD: machine building.

SUBSTANCE: invention relates to mechanisms of loose materials classification by coarseness. Vibration classifier comprises base capable to vibration motion, on which supporting sieves with vertical parallel surfaces are fixed, separating alternating inner and outer channels with possibility of raw material feed into inner channels and separate fractions discharge from inner and outer channels. Inner channels have width of not more than triple nominal size of particles supplied for raw materials classification. Next to output from inner channels there are vertical lateral barriers with height of not less than one-third of sieves height attached to said base.

EFFECT: increasing classification efficiency, as well as reducing sieves clogging degree.
