On the basis of analysing the operation parameters and the load-detecting features of tube type ball mill

and directing against the insufficiency of single load detecting method

a soft-sensing method for tube type ball mill based on information fusion technology of multiple sensers has been put forward.Through composite network

the noise

the inlet negative pressure

the differential pressure between outlet and inlet

the outlet temperature

and the motor current of the said mill have been fused

the load of ball mill and its varying rate being obtained.Providing with accurate information for realization of effective control of the tube type ball mill.Practical test shows that the said method can accurately reflect the ball mill's load

having comparatively high sensitivity.
