GRINDER Russian patent published in 2014 - IPC B02C13/00 

FIELD: process engineering.

SUBSTANCE: invention relates to grinders and can be used for grinding of carbon-bearing material, for example, TEG, soot, etc. Grinder comprises loading bin housing 1 connected with cylindrical grinding chamber housing 2. Loading bin 1 is composed of closed chamber accommodating vertical rotor 3 with grinding elements 4. Said elements 4 are composed of helical hinges with smooth surface and arranged to allow different-direction spinning relative to each other. Loader 5 composed of pipeline is brought to loading bin 1, said pipeline being equipped with piston 6. Grinding chamber 2 is arranged coaxially under loading bin 1. Rotor 7 is fitted on vertical shaft in grinding chamber 2. Grinding elements 8 are composed of multi row system of horizontal blades.

EFFECT: higher efficiency of grinding of low bulk density of materials.
