DEVICE FOR SEPARATION OF MINERAL RAW MATERIAL Russian patent published in 2003 - IPC

FIELD: concentration of minerals; devices for radiometric separation of ores. SUBSTANCE: proposed device has bin, transporting mechanism, radiation source, air and mineral luminescence intensity measurement unit whose output is connected with first input of mineral luminescence signal measurement unit and input of air luminescence intensity measurement unit whose output is connected with second input of comparison unit and second input of mineral luminescence signal measurement unit whose output is connected with command generation unit which is connected with actuating mechanism. Air luminescence intensity measurement unit consists of minimum signal detector and follower; input of minimum signal detector and output of follower are respectively input and output of air luminescence intensity measurement unit. EFFECT: enhanced accuracy of measurement. 1 dwg
