FACILITY FOR MECHANIC ACTIVATION OF SULPHIDE CONTAINING MINERAL PRODUCTS Russian patent published in 2008 - IPC B03B1/00 B03D1/00 

FIELD: mining.

SUBSTANCE: facility for mechanical activation of sulphide containing mineral products consists of cylinder case with input and output sleeves, of mixer and vertical riffles arranged in case on one shaft. The facility is equipped with additional vertical riffles assembled on interior walls of the case. The riffles on the interior walls of the case and riffles on the shaft are arranged radially and correspondingly ones against the others. Width of the riffles arranged on the case is 0.15 of case diameter, while width of the riffles located on the shaft is 0.2 of case diameter. Width of the gap between the riffles assembled on the case and riffles assembled on the shaft is 0.1 of the diameter of the case. All riffles are arranged at one level at the distance of 0.1 of case diameter from the upper edge of the case, and at distance of 0.2 of case diameter from the bottom of the case.

EFFECT: upgraded efficiency of rubbing kish off mineral grains and restoration of flotability of mineral products; also reduced power consumption at mineral products mechanical activating.
