FIELD: process engineering.
SUBSTANCE: invention relates to material crushers. Proposed device comprises hollow cylindrical housing with loading funnel and lengthwise grooves on housing inner side surface rotor shaft arranged aligned inside said housing and having lengthwise grooves on its outer side surface opposite those on the housing. Housing can revolve in opposite direction relative to rotor shaft and has shall ring of outer side surface to form constricting chamber together with the housing outer side surface. Heating elements representing HF electric charges and HV power sources provided with individual rotation and radial reciprocation drives, are arranged along the shell ring edges in its lower part.
EFFECT: simplified design.
