FIELD: crushing or grinding of various materials.

SUBSTANCE: invention relates to equipment for crushing and grinding various materials using electrohydraulic effect and can be used in mining and other industries. Electrohydraulic crusher comprises loading bin 1, housing with electrode 5, discharge chamber 2 combined with discharge grate and made cylindrical in form of assembled structure, consisting of a set of elements compressed by means of screw pins with nuts between the upper and lower flanges and forming horizontal slots for the entire height of discharge chamber 2, discharge chamber is equipped with a conical bottom and is placed inside the cylindrical discharge chamber, which is equipped with a bottom and a discharge branch pipe fixed in the centre of the bottom of discharge chamber 4. Set of elements of discharge chamber 2 includes annular disks of the same size with radial slots located horizontally one above the other in the cylindrical part of the discharge chamber, and solid annular discs arranged horizontally one above the other below the discs with radial slots and having the same outer diameter equal to the outer diameter of the discs with radial slots. Upper solid disc has inner diameter equal to inner diameter of discs with radial slots, and the disks located below have a gradually decreasing inner diameter and thus form the conical lower part of discharge chamber 2.

EFFECT: crusher is characterized by increased efficiency and durability of the device.
