DEVICE FOR MONITORING CONTENT OF SLIME IN MAGNETIC SUSPENSION Russian patent published in 1994 - IPC

FIELD: concentration of useful minerals. SUBSTANCE: flow-type chamber of device with spaced in height pressure taps 2 accommodates induction coil 3. Pressure taps are connected by means of pulse tubes 4 with transducer 6 of magnetite content signal. Output of transducer 6 is connected with slime content unit 14. When fluid passes vertical section of chamber 1 pressure differential arises which is monitored by pressure tap 2. Pressure differential is taken up by density signal transducer 5. Signal from the latter comes to unit 14. When suspension passes through induction coil emf is induced which is proportional to magnetite content in suspension. Signal arrives at input of transducer 6 and, then, comes to unit 14. At output of unit 14, signal is formed. EFFECT: higher efficiency. 1 dwg
