VIBRATORY CONE CRUSHER Russian patent published in 2020 - IPC B02C2/00 B02C19/16 

FIELD: crushing or grinding of various materials.

SUBSTANCE: invention relates to devices for crushing of solid materials, namely to inertial cone crushers with vertical axis, and can be widely used in mining, metallurgical and construction industries. Crusher comprises housing 1, cone 2 and platform 3. Working surfaces 4 of housing 1 and cone 2 form crushing chamber 5. Housing 1 is connected with cone disk 2 by springs of upper tier 6. Disk cone 2 is connected to platform 3 by springs of middle tier 7, and platform 3 is connected with support 8 by springs of lower tier 9. Shafts 10 of unbalance vibrators 11 are installed on peripheral part of platform 3 symmetrically relative to vertical axis of symmetry 12 of crusher with possibility of stable self-synchronization of unbalanced vibrators 11, at that, to ensure stable synchronous-antiphase mode of movement of housing 1 and cone 2, condition

is observed where m₁, m₂ are, respectively, weight of housing and cone, kg; is weight of platform taking into account masses of unbalanced dipoles, kg; b is the shortest distance between the shaft axis of the unbalanced dipole and the centre of mass of the platform along the horizontal line, m; d is shortest distance between shaft axis of unbalanced dipole and centre of mass of platform along vertical, m; a₃ is the shortest vertical distance between common centre of mass of crusher and centre of mass of platform in position of static balance of machine, m; I is equivalent central moment of inertia of crusher, kg⋅m².

EFFECT: crusher is characterized by high efficiency of crushing and reliability of operation.
