Frequency domain characterization of torque in

Ball mills have a low efficiency rate partially due to the lack of a proper method to monitor the mill filling level, which makes it difficult to control the grinding process. The purpose of this paper is to explore the possibilities that DEM offers to characterize the load torque of tumbling ball mills in the []

Extending the application of JKFBC for gravity induced ...

2017-2-1  Besides the feed, the energy input regime to the mill is a significant factor. The energy input depends on the number of revolution, applied load on the ball and rotational speed. Torque signal (from torque sensor) is the direct measurement related to the energy consumed by the mill. The mechanism of torque draw in JKFBC can be express in Eq.

But the rock also swells the charge, moving the center of the entire mass closer to the center of the mill, and thus decreasing the horizontal distance (d). The product of the new (larger) W times the new (smaller) d with the feed on is normally lower for mills operating with typical ball load levels. So the power falls when the feed comes on.

ETAP Motor Starting Study for 600kW Ball Mill -

The problem with ball mills vs a simulation like ETAP is that the mill initially is a torque load that is dependent on rotation angle until the charge start to tumble. ETAP only simulates the torque vs speed as a curve. Best bet would be to use a torque peak right off zero speed and then drop down to a more constant torque type of load curve.
