METHODS OF FILLING AND EMPTYING BALL MILL WITH MIXER BY MOVING AUXILIARY CRUSHING BODIES BY MEANS OF HYDRAULIC TRANSPORTING MEDIUM Russian patent published in 2016 - IPC B02C17/16 

FIELD: construction.

SUBSTANCE: invention relates to a grinding ball mill with mixer, specifically to methods for loading and removal of auxiliary crushing bodies. Crushing bodies are contained in storage hopper (14) together with hydraulic transport medium (16). Crushing bodies (12) are transported into a mill (10) in closed hydraulic loop through hydraulic transport medium. Transport medium is sucked by pump (20) via first conduit (22) and via second conduit (24) is pumped through grinding chamber (11) of mill. Crushing bodies together with transport medium is sucked or forced into grinding chamber. Crushing bodies remain in grinding chamber. Transport medium by means of pump is pumped from storage hopper through second conduit into grinding chamber. Crushing bodies with transport medium via first conduit are pumped from grinding chamber into storage hopper. Auxiliary crushing bodies remain in storage hopper. Transport medium is passed in loop until all crushing bodies are removed from grinding chamber.

EFFECT: invention improves loading and extraction of crushing bodies from mill.
