BALL MILL METHOD FOR DETERMINING THE

2014-9-23  1.1 This method determines the resistance of aggregate in flexible base material to disintegration in the presence of water. The test provides a measure of the ability of the material to withstand degradation in the road base and detects soft aggregate that is subject to weathering. The result of this test is the Wet Ball Mill (WBM) value.

Testing method for ball mills - Outokumpu Technology Oyj

The testing steps are arranged so that the first step for the testing method is a semiautogenous test, which is followed by a ball mill test. Due to the fact the test is carried out in two steps, one can make accurate estimation for capacity and energy requirement for the two products in respective process steps, thus optimize the energy ...
