impact stress in ball mill - walkingonwaterfl
Data from drop ball tests seem to be fairly well confirmed by in-mill tests with the hollow instrumented ball which, although heavier, is larger in diameter, less convex, softer steel, and strikes either the tumbling mass of ore and balls or descending mill liners. The ball was placed and recovered in the feed end of the mill where impact is ...

Assessing load in ball mill using instrumented grinding ...
Monitoring mill load is vital for the optimization and control of grinding process. This study proposed the use of an instrumented grinding media to assess solid loading inside a ball mill, with size and density of the instrumented ball comparable to that of the ordinary grinding media. The acceleration signal was captured by an embedded triaxial accelerometer.

Ball Milling | Material Milling, Jet Milling | AVEKA
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...

In the ball mill, the motion of charge is a complex system, especially under wet grinding. It is difficult to measure the charge physical quantities and hard to validate the correctness of charge motion simulation. To this end, an instrumented ball which is capable of measuring the charge physical quantities was designed.
