FIELD: equipment for grinding of bulk materials, preferably resilient materials.
SUBSTANCE: method involves feeding bulk material and grinding between movable and immovable cones; creating bulk material vibratory fluidization mode in converging annular gap between movable and immovable cones at vibration intensity γ=αω2/g>10, vibration amplitude α≤10-3 m of movable grinding cone; removing resulting ground product by means of adjustable air flow through particles delivered for grinding process.
EFFECT: provision for producing of fine powders of bulk materials in continuous operating mode, increased efficiency and reduced consumption of power.
