Lab Report 1 and 2

Dec 28, 2013· Ball mill is a metal cylinder which rotates about its horizontal axis. The coarse sugar charged along with the metal balls breaks to fine powder by impact of metal balls. This angle is in the range 0°–90°. In this experiment, we were measuring the angle of repose of the sand with 355 micron, 500 micron, 850 micron and various sizes
